Engine switch

[Big Jets]

Anyway here,s my quandry,Ive got a r100r lying in the corner which is not 100%( long story),and my wee st which is the apple of my eye at the mo ,anyway cut to the chase ,the st,s gearbox is on its way out I think, so Im considering a engine and box swap, Are there any problems with the switch ,the r100r exhaust are fatter so will the st pipes fit or do I need different header pipes ,and does the para gearbox fit easily into a mono ,cant afford any expend on this so its got to take place with what I got ,any advice would be much appreciated .Cheers

They should both have 38mm downpipes so the exhaust shouldn't be a problem. The gearboxes are a straight swap but the output seal on the paralever box is different it's only designed to stop oil coming from one direction you will need to swap it for the earlier seal.
