Is the XB12s engine good for active driving in 5-6000 rpm for longer periods? | ||
| Elff |
It sure smoothes out at 4k | ||

Do you really need to go 100-120mph for an extended period of time?  | ||

Elff: It sure smoothes out at 4k Yes I know, but does the engine handle 5-6000 rpm over longer periods? | ||

Pwnzor: Do you really need to go 100-120mph for an extended period of time? It does happens that I race against my buddies once in a while... | ||

Sorry, I should have answered your question. Last year I rode from Long Beach, Ca to San Francisco, Ca on Old Highway One, 465 miles in under six hours. That includes stopping to eat and get fuel. Bike never complained about it once. Of course I changed my oil before the trip and again when I returned home, so only about 1200 miles on that oil change. So I guess my recommendation is this: the harder you ride, the more you should change your oil. (Message edited by pwnzor on August 29, 2006) | ||

unfortunately I really dont know A good gauge might be how well they hold up for the racers. They run in that range for the entire race | ||

I ride mine all day between 5 and 6 revs in all gears, no prob. | ||

same here... no problems yet. | ||

same here... my engine blew at 12,000 miles with a ton of track use. be sure to view this alert: http://www.badweatherbikers.com/buell/messages/32777/155801.jpg if i only knew then what i know now.  | ||

When you say your engine "blew" what do you mean? Can you describe the failure for us? | ||
| Dago |
the generally accepted theory (blake's) is that the compensator nut came loose, freeing the oil pump drive gear to be ground thus releasing metal shavings through my system that then compounded the problem to total destruction in a very short amount of time. the bottom line is that it all most likely could have been avoided if the nut had been tightened to the new torque spec. | ||

Ahh, I see... bummer. What was the outcome, was it under warranty? | ||
| Dago |
it was fully covered by BMC and back into my garage within about 10 days! | ||

One thing I've noticed about Buell engines... if you keep 'em in the normal rev range (around 3,500-4,500 rpm) they run as well as anything I've ever owned. Keep 'em up near redline and you better keep an eye on your oil level!! Several years ago I did Reg Pridmore's C.L.A.S.S. at Pocono Raceway. I checked my oil before I left my house and the level was fine. I rode 120 miles to my friend's house in the Poconos and rechecked the oil. The level hadn't changed. After one day of C.L.A.S.S. (Pridmore is big on running in lower gears in higher RPM's for easier throttle management) I found I had to add a full quart of oil to bring it back up to an acceptable level! After riding home that night (another 120 miles) I once again checked the oil and there was no change from when I added it earlier in the day. Fast forward to this past May. I rode my XB12Ss the 120 miles to the Poconos; again no change in the oil level. Halfway through the day with California Superbike School (Level III) I found I had to add about a half a quart of oil to get the level back where it belonged. At the end of the day I had to add yet another half quart. When I got home that night, the oil level had not changed from the last time I'd added any. Buell (Harley) engines seem to consume a LOT of oil if you run them constantly at high rpm. This was never an issue with either my K100 (flying brick) or R100RT (airhead), both of which were used on the track in the same manner. | ||

That's what I wanted to hear Dago! | ||

i run my up to the limiter almost on a daily basis. I use mine as my primary means of transportation and check all my levels all the time. It has not left me stranded yet and runs great. | ||

Last October, ran from Pinehurst,NC to St. Louis. Normally a lengthy trip, I made in a very low time, bike ran purrrrfect all day long. Stopped long enough to fill up and shove a Snickers bar in. I also did what PWNZOR did, changed my oil before trip, had to top it off up there, maybe 3-4 ounces, and changed the oil after I got back. So I would also say that running it hard will not be a problem,personally I think these bikes like to be flogged instead of baby'd,just make sure you check your oil levels more often! |
