    Hokey dokey.
    As some of you know, 12oclock wheelies are a cunt, due to the bike stalling by lack of fuel.

    So i need to raise my carb up to a 45 degree angle When it's flat.
    So it's at almost a flat angle, when the bike is parked at 12oclock.

    I've heard the malossi straight inlet, only fits the 25mm carbs?

    I need some help as to what to buy.
    Thank's in advance.

    malossi/polini straights take anything from 21 to 30 if you do it right.. theres 2 sizes. best way is make up an angled spacer for between the manifold and reedblock. take a traching of the reedblock, make an 8mm copy of it in flat ali then angle cut it/lap/machine it down to 1mm on one side. plenty angle there.

    the next prob your gonna have is the fuel tap/pump but theres an easy fix..

    minor knows look :p crash bung is possible but involves either drilling or welding your frame to make it worth while do not know how paky has done his ?

    Paky's gone quiet one me.

    I'm more than willing to butcher my frame for the sport though =)
    Have you got paky's pics?

    Thanks minor.
    Sounds like a lot of effort, but i'm sure i could give it a go.

    stupid as it sounds, wouldnt you be better with the carb 90 degreese to the bike then no matter what angle your wheelie is at, the carb stays level, although going round corners may be entertaining.

    If the carbs at 90 it's not going to work when the bike is flat on the ground is it?

    Oddly enough i do ride with both wheels down occasionally.


    Shiny, i live 2-3 miles from crazy eyes mate.
    Looking forward to the spacer, still need to order me an inlet when i get paid.

    I had a straight manifold on the stock runner carb, the mhr stubby one and it fit fine so you shouldnt have any problems.
