Besides killing my brother what should I do? My brother took my bike for a spin today(XB12R) He took it all the way to redline and then missed the shift to 2nd. Over rev while in neutral and in the panic he slammed it into first. Engine made all sorts of funny noises, sputtering and stuff. I rode it home and I'm not sure if I'm just panicking but I think I can hear the lifters when I couldn't before... Should I be worried? How can I tell if he damaged it? | ||

He just hit the rev limiter. It did what it's supposed to do, and the noises are what happens when you hit the limiter. The bike will be fine, just don't let him ride it anymore.  And don't make a habit of over-revving the engine. Mike. | ||

Ouch! Bet you bent a valve or at least a pushrod or 4. | ||

The story gets even better. He was in second and instead of shifting up to third he shifted down to first. His riding days are over, at least on anything I own...... Greg, if I did either of those would the bike still run normal? Like I said I did ride home. besides the noises, which may be in my head, the bike seemed fine. | ||

You can overrev the motor even with the governor in place by downshifting while the rpms are way up. The spark will be killed, but the motor will be forced to rev higher simply by the rear wheel & tranny. If you are hearing noises, they may be in your head, or there may be a bent pushrod. Get someone you trust to either listen to it, or check it out. | ||

I should have read the first post more carefully. Hopefully, once he realized he slammed it into first by mistake, he settled down and got it into the proper gear or just stopped the bike. These bikes make lots of noises and I can't say I would know by listening if anything like a bent valve or pushrod happened to mine. To be safe, you probably should see your dealer. Mike. | ||

I pulled a similar trick on my Cyclone during a race once. I once was distracted by a thoughtful track marshal who was puttering along on his XR100 near the edge of the track. Kinda freaked me out for a second, got me out of my groove so to speak and I forgot for a moment that I had GP shifting. At 80-85 mph I went to 2nd instead of 4th gear. I thought for sure I had destroyed the engine. I pulled in the clutch as soon as I noticed the goof and shifted up into 4th, let it back out slowly, thinking to myself, please-please-please... it seemed to be fine, so I wicked it back up and chased down another victim. Finished that race, ran another that day and have since put on thousands of street miles. No problems. If the bike is running fine, I wouldn't worry about it. As to the noises you perceive... Check your primary chain tension? If you are really concerned though, you can drain the oil, remove and dissect your oil filter. If you find any unusual quantities or bits of metal inteh filter or oil, you might want to have your engine looked at by a competent professional. The thing is under warranty though, right?

I've had a number of bikers at the office and a Harley Mechanic (by no means a Buell expert, but a good buddy of mine) listen and ride the bike. (I'm sure some just took advantage that I was offering.) We also started another XB12R in the showroom. The consensus is that the bike is OK. As far as my brother, Let's just say the bruising should go away in a couple of weeks and he will not be asking to take the bike again. OK so he is 18, he may ask but he will not get……………… | ||

Don’t try this at home, but……..I ride up to the rev limiter every time I go out. For some corners it not worth hooking up the next gear only to go straight down a few feet later, so in the normal course of riding, hitting the limiter has been fine – that’s why its there. This year I converted to GP shift (1 up 4 down). In the process of teaching myself to change gear the other way round, there have been several mistakes and some serious over revs (not to mention some underwear cleaning moments). All without any apparent harm to the motor. IMHO, I would say if the bike is running fine (like up it spins up to the limiter like it used to), then its OK. Mark. | ||

You'll know if you did decent damage. I've heard bikes that have been over revved and they don't hold back. Very noisey and run like crap if at all and are extremely lacking in power. |
