.060 Over
Hi have a 2006 rocket 3 with around 22000 miles on it and thought I would inspect the cam chain tensioner as recently I could hear a little light ticking while the engine was running. I removed the centre bolt on the tensioner and noted the spring free length was 70mm and the drop in the tensioner was 25mm so almost on its limit. There was no spacer fitted as there should have been when the drop measures over 16mm
Looks like its time for a new cam chain. The rritating thing is that the bike was in the dealership 6 months ago with the engine out getting the TDSU bearings replaced as one had failed and having the detent spring and second gear assembly replaced with later updated parts. I had told them to go over the engine with a fine tooth comb while it was apart and if anything looked doubtful or worn to contact me and let me know so I could decide what to do. Guess they missed the tensioner being at nearly full extension.
Conveniently, I am currently waiting on the new engine cover and clutch parts coming from TTS as the clutch plates are due for replacement and I figured I could fit some of the parts from their supercharger kit while I have the front cover off to do the clutch.
So I ordered a new cam chain tensioner spring and next I need to order a replacement cam chain so I can do the work myself. I see that triumph sell a kit with a new cam chain and cam sprockets in it however I dont know if this includes the bottom sprocket too. Are there any other parts worth replacing while I am in there as I am unsure if my bike will have had the updated lower cam sprocket and cam guides in it.
I have heard that to replace the cam guides one must remove the head, is this true? Or will they even need replaced? I actually have a new set of APE adjustable cam sprockets that I got some time ago as they were a good price and I figured they may come in handy some time in the future so I could install those with the new chain providing that they arent too much of a nightmare to dial in and set timed at the stock position. I do own a degree wheel from when I used to mess around with 2 stroke tuning a few years back. I haven't had a look at the workshop manual yet so will any special tools be needed in the process and how much of a nightmare is it setting up the adjustable sprockets? Would I be better just putting a set of stanard ones on?
Thanks for your advice.
