Exup or not to exup, that is the question.

The difference isnt that great, unless your a purist, take it out, and keep it knocked down a gear! 8)

I removed my exup valve on my previous thou and, apart from it being a little louder, didn't notice much difference in performance.
My current fazer has never had its valve looked at in 9 years and 43,000 miles and still works like new.

How do you know if you've never looked at it?   My bet is that the cables need adjustment and the bolts are probably seized, so when something does go wrong, you'll have a job on your hands to fix it.

Plough yer own furrow, folks, but 10 mins to strip and copper grease the EXUP at every minor service seems simple common sense to me.

I always thought Copper grease true application was for high temp threaded items like manifold studs etc, not for moving parts in high temps surely Yamaha could have fitted Graphite impregnated type bearings within the collector box. Still a shit conception though. (Exup that is.) :evil
