Test/tune

Post by Ridea200 »

With the snow gone, and a race coming up the family, and I have been knocking the rust off. The other day I figured swapping the stock needle for the one (oem# n2ej) from when the bike was a 125 was a good idea...Ran pretty good other than a burble mid throttle. I had just read slicknick talking about running on the 2nd clip on his setup, so I tried it. Was on the 3rd. Burble was still there, but better. Today, I figured I'd pull the carb, and at least drop the float to 18mm from 16. Ended up doing that, pulling the jet block/gasket sinching the seal, upping the pilot, and lowering the main.
Runs pretty good now.
