I've heard many stories of EXUP valves sticking or breaking on Yamaha. How do I know that my new purchase is OK in this depertment? It seems to go quite well but, compared to my previous bike (a Honda 400 SuperFour) the Yam could have square wheels and be a better performer! Because I've made such a big leap, I thought this bike would scare the pants off me. Is it OK or do I just need to take it above the 6500 revs that I've subjected myself to so far?

Hopefully I will get used to my new bike soon and I won't feel the need to ask any more silly questions.

Thanks again.

As said in your other post, if the Exup valve is seized/not working, you will find under 4000 rpm it will feel gutless.

The YZF750 will rev out at 13,500, so you got plenty to go yet.

You have to work these motors to get the benefit. :D
