Hi, I'm new to this forum and a new Kawie owner. I purchased a 2005 Brute Force 750 the other day with 2000 miles and about 500 hours on the engine. The thing seems to be in pretty good shape overall. My issue is when I put it in drive or reverse there is hesitation between when I push the throttle and when it seems to engage, and when it does engage it seems to lurch violently before it feels like it catches and drives. This doesn't seem to be an issue going above 5 mph though. I also would say that I don't believe this thing is putting all of its power to the ground, the power is a bit disappointing and it doesn't seem to have a lot of power at the top end. It runs smoothly and idles perfectly. I had it in the shop and they replaced my spark plugs. Asked them about the lurching and they said it's just old. I feel like that is the lazy answer and there is always a reason something isn't working correctly.
