KZ750 4-1 exhaust size??

14 Mar 2013 02:32

I am planning on building my own exhaust for my 750. I just want to know what the 4-1 collector output size is? I'm thinking it is around 2". I only have the stock exhaust and would like to know what Kerker, VH, or anyone else used as exhaust size so I can keep it the same for back pressure reasons.

Thanks!

Multiply circumference by .3183

I always found it easier to multiply than divide, but then again I come from an era of slide rules!

To the OP I can answer your question tomorrow. I have the Kerker but it is about a half hour away!

You guys are KILLING me! If you had a tape measure, why wouldn't you just measure the ID/OD of the collector! :laugh: :woohoo: :laugh: :silly:

the problem is where the pipes collide it is very small and hard to find a y-pipe to fit.

Depends entirely on kind of pie,I generally have found in the case of peach/cherry or pumpkin pie that the 1 pie to 1 fork generally fits into my plans rather well! :woohoo:

I can put my handle bar in the exhaust pipe and jiggle it around a bit where I cut it off so yes a 7/8" handlebar plus jiggle x (pie x 0) equals about 1 inch x 2 = about 2 inches then the baffles for restrictionary purposes = pumpkin pecan

Chicken pot pie would involve an entirely different calculus, sort of like pie in the sky, and sometimes pizza pie (if triangular slices and NOT rectangles).

Suggest consultation with the APC:
