Edited Date/Time:
Hey everyone, back again. For those that never saw the problems I've been having in my other fourm here is a quick run down:
- Motor replaced at 6 hours (3rd gear slipping and could never find the issue...5 weeks off the bike before Yamaha replaced the motor).
- Intake valves were completely out of spec and needed to be replaced (had no effect on 3rd gear).
- Starter clutch went at 4 hours on new motor.
- No warrenty/compensation from Yamaha.
- Just shimmed one intake valve that was so tight you couldn't get a 4 in it (roughly 12 hours).
I was just at a race this weekend and the bike completely bogged out before the landing off a jump (4th moto out of 5 for the day). I knew something wasn't right so I pulled off.
When I shut the bike off it wouldn't start again. I changed the filter, but nothing. When I pulled the choke out the bike would start. Without the choke it eventually began to start but backfire immediately.
The issue seems to happen when THE BIKE IS WARMED UP. Once it is warmed up it will not start without the choke/or start like a bastard.
THIS IS NOT AN ISSUE WITH THE STARTER CLUTCH. The bike starts fine after being warned up shortly with/without the choke. After it has been primed it is game over.
Has anyone had this problem yet?!
