[QUOTE="SilverSurfer, post: 1039521, member: 68283"] Ok, I purchased a used and in need of a lot of TLC 93 CR250R. I have completely rebuilt the bike to the tune of the following: 1. Rebuilt entire motor. (Wiseco piston/Hot Rods crank) 2. Replaced COIL 3. Replaced STATOR 4. Rebuilt carb (stock jets/needle) 5. New air filter/spark plug 6. Rebuilt suspension. 7. New chain/sprockets 8. New bars/ASV levers. 9. New kill switch 10. All bearings/seals replaced. 11. All new plastics 12. FMF Fatty/Spark arrestor pipe. Basically it's almost like a new bike. Except for one problem. The bike starts fine after a few kicks. On the low end it runs perfectly. It will yank the front wheel right up. However, once I hit midrange or beyond it just runs flat. It's accellerating but not like a normal 250 does. It's just not pulling hard at all. It's pulling more like a cr80 than a 250. I just can't figure it out. The jetting is spot on where FMF says it should be. It's not smoking too much and I don't think it's running lean at all. My question is WHY is it doing this? It's not sputtering from midrange and up. It's just not pulling like it should. It's pulling like it's way way too rich. Any idea why it's running like this? [/QUOTE]
