Hello all, finally decided to get on the forums since I've had so many questions answered before!
Here is my specs, I have a 2005 450r with Hrc cam, hrc lid, moose foam filter, hrc jet kit 185 Main 48 pilot, needle 3rd position. The guy i bought it from earlier had a full White bros pipe that he took off for some reason before I bought it ( I know sounds shady) but he put the stock pipe back on with the hrc tip, which I was running with out the baffle it because it made an awful vibration sound at high rpm like a loose skid plate. I'm in the process of getting a slip on so it will be done right.
Ok so here's my problem. The quad was running awesome when the first week I had it, besides a few decel pops I'm guessing that were amplified from no baffle, it ran good, no bogs at all except it would very rarely die when letting the clutch out in second which I heard could be normal for these high strung motors. It all came to crap when at a friends house I decided to race him and I was idling for about 3 mins, the idle was a bit high and my friend ran over pointing at my orange exhaust by the head pipe, being that this is my first truly high peformance sport quad I thought that it was the end of the world, only to find out that it's normal lol only at night at least and it was pitch black out, anyway i suspected it was running lean so I screwed with the fuel screw and cleaned out just the pilot, the main and the bowl, the rest looked very clean. When I put it back on the quad would not start at all! Literally 100 kicks and not even an attempt, I had to resort to giving throttle while kicking (I know this is really bad) and it fired right up, revved fine, smooth and quick. Taking off in first it felt like the idle was too low kinda like chugging along and then it takes off. The bog occurs at lower rpms I'm gonna guess maybe 3-4K ( very rough estimate) it doesn't die but sounds like a fuel cut and then once it gets out of that dead zone it runs like a top and accerlartes all the way to the rev limiter without any hesitation. I noticed it does it worse when going uphill and at a lower rpm, when going downhill it's barely noticeable but it's there. If I try to do a first gear wheelie after just taking off it also does it. Seems like it cuts out under load but only at lower engine speeds and doesn't make the quad stall just temporarily stutters.
I'm guessing it's maybe something to do with the stock pipe? But I wanted to hear from more educated people on this site
Forgot to add I tunrned the fuel screw all the way in and turned it out 2.5 turns. Does that sound about right? Thanks guys any help is appreciated
