funny you should mention that after i have spent an hour killing myself over that today
with the wheel in the air it was shaking around like mad but when under pressure no problem at all
without a laser alignment tool its hard to be sure but them lines are the best we have - they are made in a pretty accurate JIG but as time passes we lose alignment through bearing wear etc
I usually measure the length of the stud protruding with a small steel rule after a visual line up with the swing arm markings, seems to work for me.
yeah i was cleaning the chain and decided to just start her up and let her spin the wheel on the paddock stand as i sprayed the hose at it to remove the cleaner and it was bouncing all over the place- turns out it was just riding the front sprocket a bit - its fine when its under load
It's the momentum of the wheel gaining speed but the chain won't let it go faster than the engine speed, which causes that shuddering effect.
Get quite a few people freaked out by it when it happens, but as you say just a very tiny bit of throttle levels it out.
lol, that's my method for applying grease to the chain, set it spinning (gentlly).
I've a theory that it's the exhaust resonating at 6k that causes the problem. I just need someone mad enough to go flying up the road with no exhaust to test the theory
done it - for some reason people kept looking at me
Lol I too like this theory, I've often wondered if it's anything to do with the camshaft rpms, it's about this range 5-6k that the powerband kicks in.
17 tooth sprocket arrived today, big bastered... as soon as it stops raining I'll attempt to fit it and let you all know my opinion.
Looking forward to your verdict fella
