My brother's Yamaha Waverunner is running way compared to normal
1200 cc two stroke

Where would be a good place to take it?

thanks

What year/model is it?

You'd think I'd know the year and model, but I will have to ask. I wax it in the spring, and fog/remove battery in the fall. I road it once last year.

2000 Yamaha Millenium GP1200R
2 stroke triple

I have that same boat. Is it actually going slower or is the gauge reading low?

Monto Reno is close to you I think...Art Jr. Is an excellent tech. Check the plugs first...but they did have an issue with dropping powervalves into the motor.

Monto Reno is reasonable. We are on Cooch, it's on the way home for either of my brothers, and they are the ones with trailer hitches:)

The non Waverunner owner pulled the plugs last weekend. Mostly OK, #2 was a bit wet. New plugs are on the agenda for Sunday. I can put my SS2000 in and see how much slower the Waverunner really is compared to before. My Ally speedo is bang on GPS up to 60

thanks

New plugs apparently fixed it. The thing hardly gets used, but I guess all the storage fog I spray into it is hard on plugs.
