01 Raptor 660R Pops once in a while reving with out a load.
Hi, I just picked up a 01 from my friend who has had it sitting in his garage for a bout 10 years, The quad has a lot of bolt on extras and very low hrs . I am going to give it to my son and yes I am aware of the possible 01 issues.
The I cleaned the carbs for him about 6 years ago and had it running and then it went right back in the garage, I took the carbs apart and the one side was really bad so I cleaned them up and replaced the O rings and also the needle valve and seat. Set the floats to 13MM and did the clear tube check. Pilot screw is 2 1/4 out on one and 3 1/4 out on the other ( That is where they were ) and the jetting is stock along with exhaust and intake and has a uni foam filter )
Oil and plug is new.
The quad seems to run fine under load doesn't bog or sputter but if I rev it in the shop it will pop and maybe cut out for a split second if I do it to quickly , It is not the rev limiter pop/backfire but just a random one if I bring revs up slow it is not a issue.
Is this normal for this motor or do I need to re clean the carbs or adjust the fuel/pilot screw? If I need to adjust the screw would I turn it out more ? Maybe a 1/4 turn? Thanks
PS I did intentionally make the PB Safety limiter kit in to check and it def is not that.
Also I am glad it seems to run good while riding and I don't need to rev it like crazy in Neutral I was just wondering if it was pointing to a slight lean condition that I should address.
