Cold/Hot Starting Challenges with Triumph 955i Tiger

 

https://www.triumphrat.net/threads/955i-daytona-speed-triple-difficult-cold-starting.974150/

look at the ‘warm-up’ table – just increase the enrichment factor at the lower temperatures – it makes a BIG difference

It looks similar to the Idle Table but the Idle controls Engine SPEED while the Warm-Up controls FUEL Enrichment

The position for the IACV is actually set while balancing – with an already warm engine, you balance the TB’s and check the IACV position – it should be operating in the range of 30-35 steps when controlling at warm idle; if outside this range, adjust all the screws until you achieve both balance and IACV in that range. This puts the stepper in the ideal range for fastest closed-loop response.

changing the position in ‘tests’ does nothing while it is under active control – I’ve seen this claimed by others that this value will affect how it performs on overrun with closed throttle – my view is that whatever you change it to, it will be over-ridden in active control and if you go back after some time the number will not be at where it was previously set.

The other thing – recognize all that IACV does is adjust the air volume through the bypass ports – which controls engine speed – it cannot effect the fuel because there is no change to the TPS (unlike a Keihin system where the actual throttles are opening) – so the enrichment is does via the warm-up table.

Valve Adjustment Tips
I’ve adjusted the valves on several C14’s now, and on just about every one, the valves on the right side, closest to the cam chain seem tighter than the rest. On other brand motorcycles they usually tell you to loosen the cam chain tensioner before checking the valve clearances, but I haven’t found any reference to do that in the manual for the C14. I decided to go ahead and loosen the cam chain tensioner and recheck the them. When I did, it made just enough of a difference that it allowed a .006 inch feeler gauge to slip under the camshaft for the #4 intake valve, when previously it wouldn’t fit (no-go). The reason this happens is because there is some clearance between the camshafts and the camshaft bearings that is normally filled with oil when the engine is running. When the engine is off and there is no oil pressure, the tensioner pulls on the cam chain, and thus draws the ends of the camshafts down by about a thousandth of an inch so that they contact the bearing, and this makes the clearance on the end valves appear to be tight. So my advice would be next time you do a valve check, remove the cam chain tensioner before you check the intake and exhaust valves on the #4 cylinder. Just be sure to reset the tensioner and reinstall it before you hand rotate the engine to do the other valves, so that the chain doesn’t slip on the lower sprocket when you turn the engine.


The first time you remove the plastic side panels to do any maintenance on your C14, I would highly suggest taking a few digital photos that clearly show the position and routing of all the wire harnesses around the engine bay and the side fairing stays and engine braces. While there are some reference drawings in the service manual that will help, good photos will be much more useful when it comes time to put everything back together. This is especially true when doing a valve adjustment, since you have to remove the right and left side fairing stays as well as move multiple wire harnesses and the rubber engine blanket out of your way to access the valve cover. Having photos that shows how it was all arranged (from several angles) before it was taken apart will be a big help. This will help insure you don’t later have problems with harness chaffing, and everything is back together the way it came from the factory.

Valve cover leaks / Exhaust Camshaft sensor O ring


Many owners have reported oil leaks around the left side of the valve cover when the bike is left parked overnight or longer on the side stand. The oil leak is usually not enough to be seen on the ground and is only noticed after the bike is started, when the heat from the headers causes any oil that got onto the pipes to smoke. Just a few drops of oil is all it takes to cause enough smoke to be noticed on startup. Normally once the bike warms up a bit, the smoke clears and the problem doesn’t return until the bike is parked again.

The cause of this small oil leak can come from a couple of sources. The first one is obvious, and the valve cover gasket itself can be to blame. However, getting to and replacing the valve cover on this bike is more than just a small undertaking, and sometimes the gasket itself is not the real cause of the leak. Also worth noting is that the valve cover design uses shouldered bolts that butt up against bosses in the head when tightened, thus the actual amount of pressure the bolts can put on the valve cover to squeeze the gasket is a fixed amount, and over tightening the bolt will only result in pulling the soft aluminum threads out of the head. The torque spec on the valve cover bolts is only 87 in/lbs or about 7.2 ft/lbs. Owners would be wise to resist the temptation to try to fix this leak by attempting to over-tighten the bolts. Closer inspection will reveal that there is a rubber washer, (covered with a metal hat) under the head of each valve cover bolt. The purpose of this washer is to insure that the amount of pressure put on valve cover gasket is uniform when the bolts are tightened, and it also serves to add pressure to the valve cover gasket by taking up space between the bolt head and valve cover, thus causing more downward pressure to be exerted on the gasket. Over time, these rubber washers can become deformed, and this will reduce the amount of pressure put on the gasket. Some owners have suggested putting small “shim” type washers under the heads of each bolt to increase the pressure, and while this may work, if the washer thickness is not very carefully selected, it may put too much pressure on the valve cover gasket and deform it and ruin it over time. A better solution would be to simply purchase new rubber washers at a cost of under $4 each (P/N 92055-0187 ). There are a total of 6 of these washers needed so total cost to replace them all would be around $25. A new valve cover is about $40, and this could also be replaced if desired, but unless the valve cover gasket is noticeably deformed or damaged, it should be reusable without issue.


Another source of oil leaks in the left forward side of the head is the exhaust cam position sensor. This sensor is installed in the front side of the head and secured with a 10mm bolt. The sensor has a small O ring installed on it that is intended to prevent oil from leaking out of the head. The problem is when the bike is shut off, oil pools in the front left corner of the head when on the side stand, so this sensor as well as the valve cover gasket in this area is totally submerged in oil for long periods of time. If there is even the tiniest fault or gap in either the valve cover gasket or cam position sensor, oil will find a way to migrate through it. What Kawasaki should have done is provide an oil drain back hole in the front side of the head so that oil wouldn’t pool in this location when the engine is shut off. The O ring on the exhaust cam sensor also appears to be a bit undersized, and doesn’t always provide a tight enough fit to prevent oil leaks. And since  this sensor is right under the left forward side of the valve cover gasket, it can sometimes make it hard to tell if the leak is coming from the gasket or the sensor. The best way to determine where a leak is coming from is to first clean the entire area, and then see if you can observe with a bright light where the leak returns from. Another old trick is to clean up any existing oil and then spray some talcum powder around the suspect area, and then look for traces of the leak in the powder.


Folks on the COG forum have discussed the cam sensor O ring topic at length, and after some measurements of the O ring were taken, a suitable substitute for it has been located that will provide a better fit than the original. I located a place on-line that sells this size O ring for 93 cents each. If you go to http://www.theoringstore.com and search for V2.40X016.3 it should bring up a page with an O ring in the proper size. The dimensions of the O ring are 2.4mm by 16.3mm and it is made of Viton which is good to about 400 degrees F. Another source located is through McMaster-Carr (http://www.mcmaster.comand their part number is 9263K686. The only downside to purchasing them from McMaster-Carr is you have to buy them in packs of 20 for $12, so you might want to share a few with any other owners you meet at COG rallies if you order a pack from them.

You will have to remove the right side plastic to access the bolt to remove the exhaust cam sensor, and access in this area is tight. Removing the radiator mounting bolts and pushing the radiator forward will give you better access. You might also want to tighten the exhaust header nuts while you are in there. When installing the sensor with this new

O ring on it, you will probably notice that it can be a bit difficult to get the sensor back in and this is due to compression required on the larger O ring. Be careful that you don’t cut or nick the O ring on the sharp machined surface of the head when installing it. You may need to lubricate the O ring some to get the sensor in, and a little persistence and force will probably be needed. Just be patient and persistent and you should be able to get it to fit, and once you do, it should no longer leak and you shouldn’t have to ever mess with it again for the life of the bike. It’s also worth mentioning that the intake cam position sensor uses this same O ring, but due to its top mounted position on the valve cover, it does not seem to have a problem with leaking.

Canadian School Library Association’s Treasure Mountain 8 Research Symposium

Cyber is complicated because it exists throughout digital technologies, yet very few people have any idea how any of it works.  Marshall McLuhan famously said, “the medium is the message” as way to recognize that how we transmit information changes the message itself.  




I made this graphic for my action research project with Canadian School Libraries. You can’t understand the medium if you’re oblivious to the message. I developed a multi-award winning program that produced some of the top digital skills in Canadian students. In thanks for that I’m told I should got back to teaching English if I return to the classroom, giving you an idea of how seriously Ontario is at meaningful cyber-education.

Dorks

 Madness, right? Let’s compare how we (don’t) teach cybersecurity skills in our schools to how we *do* offer first aid training.

Last week we were in Newfoundland doing digital skills outreach, cybersecurity and emerging technologies outreach with Skills Newfoundland and schools across the Avalon Peninsula. While out there the mighty Micaela, a teacher in her first years of practice at Waterford High School asked if we might try out the new Google dorking lesson I’d developed after taking The Canadian Centre for Open Source Intellence’s analyst course. (The Canadian OSINT Centre).


Dorking is an interesting case in point. It’s something anyone can do. You don’t even have to learn how these days because AI will create the dork commands for you. What it essentially does is use specific operators like file type or site type to enhance a search. You could just type in “Canada’s role in the War of 1812” in a Google search, but if you typed in: “war of 1812″ “Canada’s role” filetype:pdf OR filetype:ppt OR filetype:doc) (site:edu OR site:gov OR site:k12.* OR site:sch.* you return a search of only documents (PDF, PPT, DOC) from education sites (.edu, .gov, .k12) that include the text “war of 1812” and “Canada’s role”. Try both and see the shocking difference in results. I’m told we shouldn’t teach this because students might find nasty things on the internet. Better that they do that on their own, I suppose, because those nasty things are on the internet anyway.

I’ve been given various excuses over the years including that this sort of material might be upsetting to students or that teaching students these skills will make them dangerous. There are interesting parallels between first aid and cybersecurity education that I’d like to consider.

First aid training is inherently unsettling (you’re learning how to act in an emergency situation where your lack of action could lead to death – it’s intense!), but no one is about to say we’re cancelling first aid because some might find it upsetting. The value of having more people with these essential skills is obvious when the blood starts flowing.

Cyber injuries through crime and foreign attacks cost Canada in the vacinity of four billion dollars in 2024. For comparison, we spent 5.75 billion in total on national policing in the same year. These cyber loses have huge emotional and physical costs, but that doesn’t move the needle on public education’s engagement with cybersecurity skills development even with all that financial woe. We’ve also had a rash of cyber-attacks aimed *at* education but this doesn’t stop the ‘head in the sand’ approach to cyber everyone feels most comfortable with.

Learning first aid would also allow you to hurt people more effectively, but that’s hardly an excuse not to teach it. The skills themselves aren’t good or bad, it’s how they’re used which matters. A doctor could go all Hannibal Lector to great effect, but that’s hollywood. The vast majority learn medicine for good. How would learning cyber skills be any different?

A student asked me why I’d be teaching them to ‘hack’ at our first dorking session. My reply was, “I’m not teaching you how to hack, I’m showing you how technology works – this is literally how Google search is meant to work. There are bad people out there using your ignorance against you, I’m giving you some digital kung-fu to fight back with.”

I only wish more education, union and ministry officials felt the same way. If I see cyber-education at all it’s performative poster making during cyber month in October, but these are skills we can teach that not only defend our students, their familiies and communities, but also opens pathways to high-demand careers. Cyber-skills development isn’t someone else’s job. We languish as one of the least digitally skills developed countries because public education isn’t prioritizing this increasingly important skillset.

Signal Hill where Marconi received the first transatlantic radio signal in 1901. In the century and a quarter since communications technologies have radically changed the world. We need to keep up!

The peril involved in it is (and this might come to a shock to you) but there are many nasty things on the internet and this kind of advanced search skill might uncover them, but so could a game session on Roblox. Our preference in Canadian education is to ignore the problem and hope that someone else takes care of it. Imagine if we did that with first aid too. The reasons for this depend on which public education stake holder you talk to. Boards and ministries will play the funding card believing that it’s cheaper to ignore it. It isn’t. For  – though it isn’t.

A grey fox on a hike around Signal Hill – we need to start getting craftier like foxes with how we deliver digital skills development in Canadian education.



The peril involved in it is (and this might come to a shock to you) but there are many nasty things on the internet and this kind of advanced search skill might uncover them. But our preference in education is to hope that the digital ignornance we have so carefully nutured over the past two decades will protect students from that nastiness – I can tell you it isn’t working.
