    Newbie there - got lots of issues

    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

    if the reverse light is on then the reverse rev limiter is on also. there is a green/white wire that used to be hooked above the shifter, you need to find this wire and ground it, this will disable the reverse rev limiter and allow the bike to run. if you bypassed the pb you need to bypass the wiring at the bars also.

    Great thanks - that helps a lot. So it it good enough to loop the wires at the clutch so that they complete the circuit? Will the PB also kick in the rev limiter?

    1-sounds fine but you need to plug the wire back in to itself
    2-yes that's the reverse sensor. that's why the light is on all the time. if it's solid. try grounding out the green/white wire. Should get rid of the light and the reverse rev limiter.
    3-Lean or very rich jetting, out of spec valve lash, improper fitment of the carbs onto the boots, a boot tear/cut/leak, or bad diaphrams can cause this.

    If it is the reverse or parking brake limiter it will run fine when in neutral or with the clutch pulled in, though I'm not sure what the effect of the completely missing reverse switch has. You need to plug the parking brake electrical lead back into itself and ground out the reverse wire (if you still have one) and then try from there IMO.

    Thanks MD - I found the green/white wire and grounded it - it looks like there's no PB rev limiter on the '05's - I cleaned the carbs I had, but they were in sorry shape - I bought a second set on Ebay and got it running. I still need to dial it in, but no issues with hitting the rev limiter.

    I did see the reverse like start flashing though.... so, I've gotten a lot closer.

    Again, thanks for responding to my post.

    Found the answer to that as well - seems that if the idle is too high, it'll blink. I don't have my cables run to the throttle yet, I was testing it an holding. I was confused as to why it'd blink in the R - but after thinking about it it makes sense. The Rev Limiter kicks in so you don't go 30 mph backwards.... so if you defeat that or if the engine is running fast, if you dumped the clutch you'd take off backwards, more or less out of control - so they're telling you "hey, dip, be caseful in reverse!!"
