Hey guys wondering if I can get some advice here on properly selecting the best needle height. I recently swapped out the cobra slip ons that came with the bike when I bought it with Dales complete exhuast. The bike had a dyno jet stage one kit on it with stock filter and dj 170 mains. I swapped out the mains with minuki 155's and added the K&N and removed the Y on the air box. Pilot screws are 2.75 out. I live in NJ in case that helps with altitude..
The needles were originally set at the third clip from the blun end so I left them there when I put on the holeshots and drove it for a little while like that...Seemed to have a stumblle at around 6-6500 rpms, but not sure how fair that is considering that I since found I had a small exhaust leak because I didnt tighten things down enough.
Anyhow I moved the clip to the 2nd from the blunt end and it seemed to run good, didnt notice any stumble. Didnt seem to notice any change in performance as she warmed up.
I then wondered what it would perform like if I richened it her up a little so I moved the clip down to the 4th from the blunt end. Also runs good, so stumble , and its smooth. No noticable change in performance as she warms up
Am I missing something. Seems to run good in both the 2nd and 4th clip posistion. Never re tried the 3rd position after I fixed the exhaust leak. Can anyone help me understand the best way to figure out what I should be looking for when comparing different clip positions.. She definately runs 100% stronger now vs when I had the cobra slips ons on her. Any advice would be greatly appreciated. Thank you
