My buddy just picked up an 08 king quad 750 and we've noticed a few things that don't seem right.

Does anyone else have a pretty wicked shaking at about 1/8th throttle? His does so hard you can see the rear fenders flapping. My brute force is a twin and doesn't shake anywhere near as much.

Also we were in the rain and all 3 headlights fogged up on the inside about an inch from the bottom. Now 1, ok a little seal issue but all 3? Thats a bit much.

Does anyone elses do this? We would just take it in but we got a big ride planned for this weekend and don't want the quad stuck at the dealer.

 

On the slightly above idle shake.my 450 has same issue,as I was slowly decendind hill,so much shake I thought I had brake issues,till I figured it out.A slight increase in throttle&it would go away.Any large one lungger has a lotta vibration.even some twins.It has a counter balancer that takes out about all the shake at higher normal engine rpm`s.Their is a "spot" in the rpm range that it will still show(shake) thru,and is at slightly above idle on the KQ.My Honda 300 didn`t have this issue,buw was a little buzzy all the time,not bad though.
Just my idea,but sure it`s correct.
No ideas on lights,just check seals.
