Bike carb angles
DIY Si - 29/7/07 at 02:04 PM

Right, given the issues I'm having with the injectors on my X11, I'm looking at converting the engine to carbs. However, the injection head has the inlets at a near vertical angle, whilst the carbs are much nearer 45 degrees, if not less. Anyone know if the blackbird carbs are capable of running at a much greater angle? Or what the greatest angle they will run at is? I could always remove a bit of the tract to lower the angle if I must. Although that would require a head removal.

I would have thought that the carb floats would be effected by being mounted at such an angle.....

I agree entirely, hence the question. But I have seen a bogg bros set up with the carbs near vertical, so although not optimum, any idea what the limit would be?

on a bike a wheelie isnt a problem ?

Well yes, that's what I thought.... When you crank a bike onto an edge the carbs keep on running okay..... but then why adjust the float float valve relative to horizontal and not just a handy reference point on the carb??..... Then again, the float valve adjusts for the petrol level in the float tank, but I expect there are limits to how far it can adjust....

Confusing.....

Mmmmm, I might just whack them on and see what happens!

I spoke to Boggs about float angle. They basically said it hardly makes any difference. So like you say just stick them on and see what happens.
