Long wheelies engine lubrication and fuel loss

9 posts in this topic

Does anyone know any issues about engine lubrication on long wheelies?

Another question is how to make the carb not losing so much fuel out of the vents on wheelies?

if your on streetbike doing long wheelies oil is stuck at back of motor[but for a damaged to be done it would have to be a seriously long wheelie.its not a problem yz and wr's since oil is in frame and as it enters motor its distibuted to several different parts of motor.doing a long wheelie is no different then going up a real steep hill.have you ever heard anyone say "if you climb that hill your oil will flow to back of motor and the lack of lubrication will cause engine damage"if you have or ever do give him a good slap!

This is way off topic. Just got me thinking.

Used to fly a Citabria, a cloth covered piper cub looking fore and aft two seat high wing plane that was cerified as an aerobatic plane (flew other aerobatic planes also but they were better equipped).

Anyway, this plane did not have an inverted oil system. But it didn't matter much because it didn't have inverted fuel either. You could fly upside down as long as you could glide upside down. No longer.

Luckily, most aerobatics are completed under positive G anyway. Even if you're upside down, as long as you don't push, its still feeding fuel and oil normally. The Citabria sure is a pretty plane. I'm trying to talk my wife into an ultralight, mostly for low maintenence costs and cheap hanger space. Haven't decided which is more dangerous. My money is on the WR, as I have crashed it almost every time I've ridden, and I've yet to crash an airplane (knock on wood).

Reposition the vent lines higher and maybe a bit forward. That should keep the fuel from coming out of the vents when doing wheelies. I don't think lubrication is a problem. Honda is the one that puts pickups forward on several wet-sump streetbikes. Never been a problem on Yamahas.
