Hey Guys, My CRF250R FINALLY ARRIVED!!! I LOVE my New Bike, my wife said I'd marry it if I could... ...I couldn't argue with her on that one! Here's my 'dumb' question, what the heck is this: It came with the bike, but I'm not sure what it is I have gotten a LOT OF GOOD TIPS reading this forum, as a result I am planning on doing the following: 1. Liberal application of Throttle when breaking-in. 2. HP4M oil for Motor (after break-in) 3. HP4 oil for Tranny 4. Remove air-filter screen and use Twin-Air backfire 5. Check Valves after break-in 6. Check Spokes often. I'm not much on Jetting... I'm at sea-level in CA & have seen reports that the stock bike is a little rich. So, I am hoping that removing the air-filter screen will make it run just right. I'll wait 'till after break-in though. Any cautionary words? I'm waiting for a magazine shootout on aftermarket pipes. Side-by-side comparison seems the only way to tell the difference between pipes. Thanks Guys! See you on the Track!!!
