I am getting a growl or vibration at cruise. It is a hunting vibe. I think it is in the CVT. Also a bouncing feel in the front like a head shake. 150 Roketa. Any ideas?

i would take the cvt cover off and inspect all the parts to make sure everything is in good order, could be a weight has a flat spot or is out of place, is it the front wheel that feels like it is bouncing? if it is i would inspect the tire and make sure it is inflated and no bulges and nothing loose, also inspect the break caliper and axle bolt is tight and not bent

howdy, about the head shake, let me make a suggestion. if your scoot has a center stand, put i up there and get the front tire off the ground. then take a hammer that will stand on its head and sit it close to the tire and spin the tire slowly , noting the relative distance from the tire to the hammer handle. if there is significent difference at any point, you have your culprit the reason i'm conscious of this is that the mechanic at my dealer puts the scoot on the motercycle lift and only secures it by tightening the clamp onto the front tire. when he was installing my tail trunk he was reefing on the wrenches higher than the top of the tires and it has wobbled since. i believe he bent the front wheel at that time which introduced the head shake which it never had before that.
lotsa miles and smiles to ya

Tires could be bad . I had a knot in my TaoTaos front tire and took it back less than a 1/4 of a mile to have it replaced .
I had my wheels balanced on my Echarm since they did not come balanced and it removed so much shimmy and vibrations . When rollers develop flat spots then tend to rattle which sounds sort of like a bad bearing noise . A worn belt could be stretched so it is not as tight as when new .
I have seen where a variator weight fell out making noise and hurting performance .
How many miles on it ? How does it run ?

Just rebuilt it with a 61mm. 65 mph @ 8k rpm. Runs great. 2K miles. Dropped 30lbs. I thought the head shake was just a scooter thing. When I roll it forward w/engine off I feel a drag at one point. Clutch bell? That should be locked up @ cruise. 1500 clutch springs, 1500 T spring, new belt, really woke it up, ported, 125mj and 38 pilot. If it was smoother it would be a dynamite scoot. Oh, and I added airfoil to intake.
