mark3evo Posted Wednesday at 06:24 AM Share Posted Wednesday at 06:24 AM engine threw a valve keeper/collet max revs 140 mph - no compression on 1 cylinder dealer would not warrant as exhaust change and they know he rides bikes to race not catastrophic Quote Link to comment Share on other sites More sharing options...
JOHN-DYNOSTAR Posted Wednesday at 08:34 AM Share Posted Wednesday at 08:34 AM sorry after 2 minutes of listening. If he or any of his family "hit" the rev limiter . the engine would definitely be "toast" by the time they shut the throttle fast reactions NOT probably has really good 60' times at the drag race edit watched the vid and had to laugh at "factory defect" Quote Link to comment Share on other sites More sharing options...

It was quite hard listening to him explain, but i wanted to see the Gen3 valves and head. Valve cover was so tight, was there one screw still in place (?)

MikaS Posted Wednesday at 06:05 PM Share Posted Wednesday at 06:05 PM It is very usual there are shims around 1.80 thickness, as stock. If there was 1.58 and it should be 1.78 , there is 0.45mm clearance on cyl1 exhaust valves, too much loose on top of valve. I just wonder if there was ticking sound and he missed it.
