well i have had some trouble i nthe past with my ds650 and found many thing wrong with it one was my 13yo son could woop my tail with a kfx400 i built for him. well anyway i have a warped head bad valves put all of that on and he could still get me easy. installed a ron woods exhaust and dyno jet kit and found a hole in my diaphram and man this punk was still looking back at me.... well i tell you one thing i bought a $69.00 srp high rev cdi box and now im looking back at him smiling i can wait for him andhit it again and still smoke him............and i was looking back on time to many and got to close to my privacy fence in my back field and woiped out head first thru the fence not a good sight.. any way i bought a vapor trail tech unit and was wondering if any of ya'll use one? hey if you do not have one of these cdi boxes GET U 1. well worth it.

 

I had one of those Vapor techs, but the first time I used it it was raining and very mudding. Then never work again. I just went out and bought a GPS, it is one of the best things i bought for the quad in a lond time. It tells you your speed, how long you ride, how long you take a break, plus how many miles you put on.

 

Ive never had a problem with my Vapor Trail tech and used iyt all winter and now in some rain and mud and works great
