Put about 75 mi on the Derbi this weekend. Finally running good. I had to purchase a new jet needle, needle jet, and main to get it right. Still plan to go leaner on the pilot jet, as the adjustment is almost max lean. Overall the carb was very rich, and now after leaning it out it will pull clean from idle to redline. Much easier to ride, and not really that slow if you keep it in the 8000 and over range - which isn't that difficult.

Here are a few photos from this weekend's cycle get together in Pine Bluff, WI -

My son rode the Derbi, I rode my buddy's '65 Bultaco Metralla, and he rode his new KTM RC390. I rode the RC390 on the way back.

Almost everything and anything shows-up.
