Hi everyone!
As some of you know I'm rebuilding an 81 cb900. Ive read about issues with the cam chains failing on these bikes and I'm thinking of getting the curved guide that sorts out these issues
My question is, as someone who doesn't really push thier bike to redline and mainly cruises from a to b with the very occasional wringing of the throttle (but generlly not to silly kmh on the road) is it really recommended to spend the dosh for this item? I might like to take it on a track some day for some fun, but even then I cant see myself pushing it too hard.
Anyone have any thoughts/experience on how regularly these fail for slowpokes like me?
I like having a fast bike/car that runs well, but I'm not going to go racing or speed around town - I'm happy just doing the speed limit and cruising about.
with the carbs I want to be able to support more power if I decide to work the engine, because I like that. but I am unlikely to use all that power (hell, I'm unlikely to use even half of what it has now).
hope that clears up the confusion - I like fast cars/bikes but I don't ride fast personally. may take it for a track day, still wont be that fast.
I have the engine completely apart currently, just putting new seals and checking everything - but in terms of power right now only putting on an aftermarket exhaust.
I may in the future decide to bore it, put in a hot cam, and the respective top end supporting mods (new valves, better valve springs etc) but right now I am not.
Like I said above I like fast bikes but I don't ride fast - I also ride more than most (I ride every where, hail/snow would be the only conditions I wouldn't ride in - so all year round). so would conservative riding and the occasional "off the line" blat or rare track day be likely to cause cam chain failure is what I'm trying to determine.
Stock chain guide and tensioner are fine.
The problem is people don't adjust the rear tensioner properly. ( the one under the carbs)
The only way I've found to make sure everything is working right is to remove cam cover and watch the tensioners move (there are two tensioners)
Load reversal is ' A BAD THING' so keep motor spinning, 5~8,000 rpm is good for max engine and component life
