TTR 230 jetting

Recommended Posts

Altitude=5,500 feet.

Airbox and exhaust mod done

PJ: Moved up to 38

MJ: Came with 128, currently running 130.

Fuel Screw: 1.5 turns


Bottom end is fine. No bog from idle. When in 4 and 5 gear, in full throttle the big bogs down from mid to full.

Two questions: Should I go up to a 132 or 135.

Where do I find a TK jet? I called my dealer and they had not idea. All they could get is a 125.

There are others, but I stopped here.
