Most of the issues are with the Raptor 660.
I picked up a non-loved 2005 raptor 660 a couple of months ago and I've spent the past month reviving the thing - swapped out all the bushings/bearings/seals, etc. I've now moved on to getting the thing running.
So here's the deal - when I picked it up, I only heard it idle - the rear axle bearing were bad, so I didn't ride it. Now, it starts fine, but wont go off idle with out back firing and dying. Here's what I can tell you....
1) The parking brake was seized at the caliper, so I removed it - including the cable and the lever, cable, caliper mechanism - I installed a block off.
2) Just below the shift shaft, there's an electrical connection that has no wires coming out of it. I'm guessing this is either for reverse - the reverse light is always on - but the neutral light seems to work.
3) The carbs were nasty - Ive cleaned them, but have not rebuilt them. After reinstalling the carbs, it seemed a little smoother, but it'll still backfire and die.
4) if I pull the clutch lever, it seems to run better - it'll still backfire, but not as bad - or, I can get a little more gas on before the badness happens.
I've had some folks tell me that the parking brake has a switch that will hit the rev limiter - and I did find a thread that said reverse also hits it. I guess the bottom line is that I don't know whether it's that or wadded up carbs. I'm new to this Raptor thing and ATV, but I'm an avid dirt biker - so let me know if you have any tips.
Thanks in advance
