I have a Viva 110 that I bought my son last year. The quality of the bike is nothing compared to the new JM 110. The Viva has smaller tires and just flat out moves for what it is. The JM runs great but is really under powered due to the large rear tires. My questions are, is there a smaller front sprocket that will make 3rd gear useable? Smaller rear tires that will help offset the sprocket? I raced hime last night with my 180 lbs on the Viva and his 80 lbs on the JM and I flat out killed him. He wants his bike as fast or faster than is old one. HELP ME PLEASE!

Now with the JM 150. It runs great! I was really impressed with the power that it has. WOW it will move for an auto. But, it seems like the CVT is slipping. What it is doing is, under full throttle going down the road it bucks. The motor is not sputtering, it feels like the clutch is coming in and out. It that bucking normal? I have never owned an auto before so these are new to me.

I don't believe the 150 is CVT, if you got them from Raceway, call them and someone will help you pronto.
Smaller front, and/or bigger rear sprockets will be FAR cheaper than changing wheels and tires. John could probably help you with this too.

The 150 is CVT and should be smooth as could be, I know I have 2 of them! Not sure what is causing your problem, can't imagine the belt slipping new like that but who knows. Call John at Raceway!

 

wow. I didn't know the 150 is CVT. That is pretty freaking sweet.

Welcome to the forum Shelbyluvv! [img]i/expressions/face-icon-small-smile.gif[/img]

Im not sure about the availabilty of a smaller front sprocket. I would call Raceway and ask.

There is something wrong with your 150's CVT. Something is probubly loose or not assembled correctly. Has it been like this since the first ride?

 

I got the 150 fixed. I had to adjust the linkage between the shifter and the clutch. It runs like a dream. I really the 150. It sounds awesome too. It is a very smooth riding and running bike.

 

Glad to hear you got it figured out Shelbyluvv! [img]i/expressions/face-icon-small-smile.gif[/img]
