Do wheelies cause engines to starve from lack of oil?
I found this comment from Bill in an older thread (below). I know Bill knows his stuff and all, but I'm just wondering if there is more to this. I know two people that claim to have had their engines rebuilt due to wheelieing (and possibly reving the engine hard while doing so). One of them rides a Kawi 1000cc sportbike (not sure which model), and he said he had to have a different type of oil pan put in to fix the problem (???). He said the oil flowed to the back of the engine, but the oil pump was in the front, which caused a bearing to seize or get worn out, blah blah.
So my question is, which bikes don't have this problem, and what exactly can a guy do to avoid this problem? If there's a thread on this, please let me know cause I couldn't find it.
Ok now you can start flipping me birds and flaming me.
Just set the front end down using power you won't get any tank slappers. You only air down the tire for slow speed stuff . If you really want to learn control start leaning back to many people ride against the tank . The farther you lean back the slower you can go . If anyone tells you an engine will oil starve pulling long wheelies is a complete idiot. That started a while ago so dealers wouldn't have to warrenty used bikes exploding engines. It's a cop out and a lame excuse for selling crappy used engines and bikes.
My friend had a gsxr 600 and the dealer told him the same thing. That bouncing your bike off the rev limiter while doing wheelies starves the bike of oil. he went through two motors.
I think it's a combination of things , It's not entirely oil starvation that's impossible. Most mechanics don't know how to pull a wheelie so they just use it as a simple obvious excuse.. I hate that when a shop says you were abusing it "Sorry no warrenty".
If you think about it how long are you in a wheelie for ? the average at 80 to 120 km/h wheelie only about 5 to 30 seconds. that's not enough time to completely remove all the oil from the head of your bike. Besides that there's an average of 3 to 4 litres of oil going to the back of the engine where the gears are. On average 10 to 12 gears spinning like a turbo charged egg beater. Have you ever taken a egg beater out of the bowl what happens ? The engine has enough moving parts to keep oil flying around inside it.
Besides that I had a bike that I used for doing bike shows that had no fluids in it . Just before a photo shoot I thought I'd actually start to ride it . I put some gas in it and a battery . I went back in the house to get something and the photographer fired up the bike. I remember being on the phone thinking " theres a bike running outside " Then I realized it was mine ( never heard it run before it was a trailer queen) . It ran for 5 minutes with only a bit of assembly grease on the bearings and rings. I raped that bike for another 45000 km with no problems. Pulling long wheelies all the time.
I had another customer ( Amsoil rep ) lose a drain plug at 90 mph across a sand flat on a KTM 400 exc . He's put another 2000 km on it with no problems.
The moral of the story , who gives a fuck . The bikes going to wear out no matter what you do . If you want it to last forever then don't ride it. From personal experience it's a whole lot more fun making your bike pull wheelies from corner to corner having fun with it than being worried about what might happen.
WHEELIES IZ FUN
this what ya get to solve that problem
i roll atleast 3 mile wheelies like i'm goin to church never had the oil light come on .when i do slow 12's and what not sure it comes on but i never hear the valves chatter unless i ride it on the bar for awile then i just set it down let pump back up,oil has perservitives and lots of other big words in it that protect under xtremeriderz conditions ,the average joe's wheelies never get there bike high enough anyway or ride it long enough to have oil starvation.and another lil piece o info,bikes have enormous torque in case you did'nt notice there made for speed and what happens when you take off on a bike ,ya start pullin g's and all the fluids get forced to the back of the bike anyway so i;m sure the manufacture thought of this when they made these wonderfull toy's .ok i'm done just my 2 pennies worth
Is that an oil baffel plate or something?
Thanks for the tips guys.
