scatman Posted February 5, 2012 Report Share Posted February 5, 2012 Advice needed please; I have a 97 jtx200 which starts fine but about a minute after the choke is knocked off it starts to run rough on low throttle opening. I have had the carb off and cleaned it several times as well as the fuel tap, fuel line etc. The pilot jet is a 33 and I have been advised to fit a 35 or 36 to clean up the bottom end. I only purchased the bike about 2 months ago and changed to PJ1 silverfire oil so I am wondering if I should go to a bigger pilot? The airscrew is set at 3.5 turns out and I live at about 100m above sea level. Cheers in anticipation Quote Link to comment Share on other sites More sharing options...
bob_m Posted February 5, 2012 Report Share Posted February 5, 2012 My bike was hunting for steady idle. I have a 1996 JTR 270 & used a #36 idle jet and it idles nice and steady now. Check the gasgas web site tech area for specific carb jetting info on your bike. Bob Quote Link to comment Share on other sites More sharing options...
