I can top my 350 out at 50...Does that seem right? I have a gytr full exaust and a gytr filter if that matters...I dont know if its been rejetted but im going to buy jets...Are Yamaha's good the GYTR?

Thanks!

50 mph

have you undone the screw on the thumb throttle so you win it out so you get full throttle ,as in the uk they are screwed in so you dont get full throttle .

You have a freer flowing exhaust and intake. I'd deff have the jetting checked out. Coudl being running a tad lean.

As for the 350 doing 90mp/h. 90km/h would come out to 56mp/h. Which sounds more reasonable. I've never seen a 350 with a factory speedo either. Must be something they have to install for people in the UK...

I had a '05 350 with 13 and 14 tooth, big gun rev box, FMF Powerbomb, HMF Slip-on, p&p head, stage 1 cam, Proflow with k&n and jetted and it only got to about 62-64. Now if I ran it for another 4 minutes and down hill I may have got 68 out of it. LOL

yeah your 50 mph sounds close.... I have always heard about these 80-90mph 350's but never any real proof. I call B.S.

wheel size is not what is important, overall tire size is.
