Gas Gas Jtr200 Jetting

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

    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.
