What should the compression on a 99 Yamaha vmax 500 be? The sled has lost a lot of its pep and was going to check this first. If it not that I have no idea where to go next. Carbs?

what do you get on compression tests?
post both cylinders PSI's.
I would hope you get a lot more than 100 PSI. Our 97 600 twin gets like 125 per cylinder, and thats with 6k on it.
how many miles does it have? and does it take a while to get started? like a lot of pulls?
