Just a question with regards to stand up Wheelies,When the bike is say up or riding at an incline just wonder does it not starve for OIL even for a few seconds or whatever..,as the location of oil lines and tank seem it would just curious thats all??? | ||

Don't know about Buell's and the short duration you will have the wheel in the air, but the old choppers with the raked and extended forks that held the engine at an angle to the ground rather than horizontal killed many engines from oil starvation. Tis the reason why choppers for the last 20+ years keep the engine level. | ||

Chris, I've often wondered the same thing. Even just aggressive acceleration and braking would seem to pose a similar challenge, so I suspect that the oil tank geometry may be designed to provide a wet pump line feed for even extreme conditions like the ones you mention. Basically, leave little air space compared to oil volume in the tank, position the supply port strategically, then no matter which way it pitches from extreme wheelie to extreme stoppie, the pump always has a supply of oil instead of air. I saw Craig Jones at Laguna Seca stand his Buell stunt bikes straight up and rev them to the limit while he roasted the rear tire, one time in 3rd gear. | ||

As I recall the XB's pump oil into AND out of the crank case yes? | ||

Into the engine and out of the crankcase. If you have a service manual it will show the oiling system flow paths. | ||

I think that dry sump engines are much better for wheelies than wet sump. I have a friend who bought a Suzuki sv650. It had bad main bearings because the previous owner rode a lot of wheelies. The dealer suggested keeping the oil topped off as high as possible to help with this but I am still not sure if that is enough. |
