has anybody actually done these? alot of ppl have said they wanted to try them

 

I bought a set and will eventually try using them on a single cam motor, they seem to be too small for use on a b series but they should work great on a single cam. The best part about them is that they are cheap and the tps is plug and play not to mention they have all the vaccum lines all ready for map sensor and brakes.

 

I was looking into doing these but the maths doesn't work out for a B series. I'm now looking at BMW motor bike TB's, I'll let you know if I go ahead with it...

 

look into the suzuki hayabusa it has some pretty reasonably sized itbs

 

Try the TB's from a Honda RC51 SP2. 62mm inlet tapering to a 56.5mm plate. Don't know how easy they'd be to integrate, but they're the appropriate size for a high output engine with 500 cc cylinders.

CAT what size pistons are in that bike? Iam just trying to figure on how close the port spacing is. I figure if it has a piston size close to a b series motor then the port spacing should be pretty close.

 

Its a V-twin, so you'll have to buy sets and then fabricate the mounting system. Pistons are 500cc with about a 100mm bore. Not the easiest way, but they're among the biggest production ITBs out there. The 50mm stuff available from TWM is just too small for a really high output engine (say above 250-260 hp)

Hey cat,where can we find these ITB's your talking about?
