1986 XC400-XC500 Exhaust question

Hello,

Are the expansion pipes on the above the same, the exhaust manifold is the same dia.

Thanks

You can check the parts numbers, I don't think they are. Dynoport shows the same part number for the aftermarket pipes though. The exhaust flange is going to be a few mm higher above the cases for the 500. It is my opinion you can't really wrap enough length of pipe for the stroke of a 500 cc two stroke onto a motorcycle. The best effort involves having a loop which goes to the rear on the opposite side of the silencer. You can look at cr 500 honda kx 500 kawasaki pipes and then look at some of the pipes on 500 single quads and see what I mean. Or a ktm 380.

Hello Fran

l couldn't find part #s for the LC bikes, i looked through other (earlier) years and the 430-500cc bikes have different part #s fot the expansion chambers( tailpipes are mostly the same it seems) l mocked up the 400 cc pipe and it fits, but its real tight up against the tank as the exhaust outlet is approx 3/5" higher on the 500cc, it would melt the tank if used.

Thanks for your input,

I'm 99.9% sure they are different part numbers. I'll go check my manual.

Yep, different part numbers, anyways. Seems likely that certain brand pipes might, due to variation of design, still fit.
