Noaly125 Posted September 12, 2019 Report Share Posted September 12, 2019 Last week I found out that one of my carburetors was junk so I ordered two new keihin carburetors 35 mm put them on and now I have no low in power I can feather it through decoder half throttle and it comes alive the tighter the air screw the better it does it has 160 and 55 jets in it Quote Link to comment Share on other sites More sharing options...

Noaly125 Posted September 12, 2019 Author Report Share Posted September 12, 2019 I've only had the four-wheeler for a week and a half and I'm trying to figure this out it wasn't running off of one cylinder because of the carburetor and I swept carburetor sides and it went to the other side so that is why I ordered new cards and now it will idle find and top in is fine but it's just a low end take off Quote Link to comment Share on other sites More sharing options...

Keno Posted September 12, 2019 Report Share Posted September 12, 2019 Drop the pilot jet to a 45. See if it helps. If your carbs jet like airstrykers you'll end up around a 35.Also read this. https://www.duncanracing.com/s/KeihinCarbJetting-2015.pdf Once you get idle and the pilot set, then start working on the main Quote Link to comment Share on other sites More sharing options...
Noaly125 Posted September 12, 2019 Author Report Share Posted September 12, 2019 170 main and an 65 pilot is what it took at the motorcycle shop today Quote Link to comment Share on other sites More sharing options...
