This is my first belt driven bike/road bike. I have had a yamaha R6 and a ZZR 1200. With that being said I'm not sure if the problem I'm having with my Stryker is just a normal occurrence or an actual problem...

When the bike is in gear (any gear) and you accelerate or decelerate I'm getting am initial bucking every time both ways. Just as an example, while in 3 gear at about 40 miles per hour, if I roll off the throttle I get a slight buck as if there was slack in the drivetrain or clutch. The same with accelerating from 40 mph at a coast when I roll on the throttle I get a slight buck. It is not only at this speed/gear. More like every speed/gear unless I'm in 4th or 5 th at a higher speed, and then it isn't really noticeable. Thoughts?????



Thanks!

I got the same thing for the 1st 600 miles. It went away after the dealer did what ever adjustments they do on the 600 mile check

you can get belt tension gauges to keep an eye on
proper tension. Belt may loosen as it breaks in.

I found my belt quite loose at 400 miles. I had to adjust anyway when I changed rear tire. And it is much better now. I think most of it is in transmission though, but not likely anything to be concerned over.

Mine has the same feeling. If you have slack in the drive belt that would definately cause it. I think what you may be noticing is the engine braking and torque of the v-twin. The bikes you said you had before were inline 4's, right? They are much smoother on the throttle, and don't have that thud when you chop. I noticed mine seems worse when I lug it, shift down a gear and see if it goes away.

Does anyone live close to St louis where i could compare it with another bike?

You pay my gas and I'll be happy to come over from Texas! LOL!

I hope you can find someone to put your mind at ease. Most probably it is the belt. I've ridden lots of different kinds of engines and V-Twins are notoriously hard slammers when chopping the throttle. Lots of torque from the big cylinders both for accelerating and decelerating. You add a slightly lose belt and you get that feeling amplified.

It also depends of the dealer and how they do final assembly. You could roll into your local dealer and have the tech check the belt. If it's a little lose, thank him then go home and fix it. Or have them do it.
