wheelies and oil

[The Artist]

Ok I was just wondering, say you were doing a wheelie on a 4t bike.

Are the engines more prone to seizing (IL4's) because the cylinders are located towards the front and oil would head to the rear of the engine.

I saw a vid with someone doing a wheelie for miles and just wondering if this could harm it anyway.

Do newer bikes have systems to overcome this?

Half-lyfe, end of.

It depends on the bike - generally twins seem to be more prone to it. The issue is not with cylinders, but where the oil pickup is located.
On some bikes there are standard mods you can do to move the oil pickup towards the back of the sump and lower down to ensure it keeps squirting oil around the head etc even when it's at a high attitude.

Age bike is fairly irrelevant - sadly I don't think many bikes are designed with long wheelies specifically in mind.

Oh right.

So is it easy to move the pick up tube or is it a complete bottom end strip down as I imagin it is right in the middle of the engine.

Luke, don't suppose you wanna sell your r6 for £1800?

Still baffles me that a lot of bike manufacturers don't seem to have taken wheelies into account at all when designing their sports bikes.

How would a FMX650 (Domi single, dry sump) handle wheelies?

I guess i should know.

Engines only start to suffer when you're talking properly long ones; when you can hold it up indefinitely, basically.

Never seen a problem with engine oil-pickups placed 'wrongly' (generally at the front) doing 'learner' wheelies. The engine gets oil again fairly quickly.
(Of course, there can be other issues, such as people holding it on the rev-limiter, etc.)
While those with them placed 'well' for wheelies should be fine to carry on for ever, of course.

Wheelies are still common as muck though, read any magazine test of a sportsbike and you're guaranteed to find a wheelie picture or two in there. IMO opinion wheelies are one of the fundamental aspects of hooligan riding so I would've thought manufacturers would at least briefly take them into account. I.E not designing an engine that will chew itself up in minutes if the bike is ridden on it's back wheel.

Just my opinion.
