Bad day of riding.

[hondaracer_34]

Just thought id share my 3rd day of riding with you guys.
My buddy just rebuilt his 08' CRF250 and it dropped a valve the first 5 minutes of riding at the track. Sucks but me having a Kawi i made fun of him for his Honda, just messing around.
Anyways, we kept riding the track and about 3 hours later i go over a tripple and go into a corner and the engine dies and i here a CLUNK! noise. Turns out my sprocket bent and broke in two, my sprocket hub has broken bolts stuck in it and is bent, and my chain is stretched. What a day, eh?

think of it this way. atleast your isnt major.. and yours was probably because a rock got jammed in there. he's did because honda crf's areknown for dropping valves :devil:

[hondaracer_34]

Yeah they are. The bike did it before and he rebuilt it, road it for 10 minutes and it locked up again, busted the cases, it was a mess. He pretty much put another motor in it and it just messed up again.
Does anyone know a good Chain/sprocket combo to go with? Any suggestions are welcome. Thanks. Oh, and whats the best sprocket hub?

[Sprks450r04]

honestly, your stock sprocket hub is prob the strongest but i would go with a set of sunstar sprockets

[hondaracer_34]

I would stick with my stock sprocket hub but it bent and the bolts snapped inside of the threads. Ill probably go with sunstar since ive heard good things about them, i wanted Sidewinder but their prices are crazy. Thanks

drill out the stock hub to accept honda 450r 400ex sprocket bolts and use the honda sunstar sprocket two years running on mine no probs.
