Cam chain and Cam Chain tensioner.
Ok, whose had to get this done and at what mileage did you bother? My bike is at 36k and my mechanic told me I should replace both the cam chain and tensioner, and then when he opened up the bike he realized he could only replace the tensioner because you have to split the crank to get at the cam chain.
My friend told me his 03 gsxr is the same way, a very big job to replace the cam chain. I find it a bit aggravating that my friend whose a ford mechanic knew that my bike would require an engine removal while replacing the cam chain, when the mechanic im trusting to work on my bike and get my valves to spec tells me that its only an extra hour labor over a valve job.
So, on my bike... I have the tensioner replaced at 36k and am told to wait until 70k or so to replace the actual chain because its hard to get to. The mechanic actually told me to hold onto the $80 cam chain for another two years so we can replace it when i decide to open up the engine for pistons or whatever else at that higher mileage. I have no use to store this thing for two years, so we'll talk about that today when i pick up the bike.
My questions.... Did anybody actually have a cam chain replacement done their bike, or did you just replace the tensioner since its such a big job? At what mileage? Do all bikes require an engine removal to replace the cam chain? After some research, I see that the zx6r is the same way, and so is my friends gsxr... im just trying to figure out if there are any bikes where its a simple job so I can justify why my mechanic made me order a part that he probably knew I didn't need....just so he can tell me to hold onto it for two years and keep my parts deposit.
Also, my one friend told me that its not a good idea at all to replace the tensioner without the chain because it will wear the chain out faster....while someone else told me its common to do that since its a lot easier to get to than the chain itself. It's like the whole break in debate, or whether or not we really need 93 octane gas... hard to find any consistancy.
