I know how to do it but will it effect engine performance?
The exhaust in question is already a ‘straight through’ jobby so I don’t think cutting it down would lead to a loss in back pressure?
Perhaps low revs would be affected…? hmmmm…
The bike has carbs not FI…
Basically, Will make it **** pulling away…It will bog down and be noisey aswell
Yep. Unless you remap. Which you can’t on a carbed bike. So…you’d have to shim the needles and various other black arts.
Well that’s put paid to that idea… Rejetting carbs is a stupidly dark art…
Will leave off the can for now!
If it is purely for cosmetic reasons you can cut down the can … While the end is off fit an aftermarket baffle to give the pressure back and Robert is your fathers brother .http://www.ebay.co.uk/itm/MOTORCYCLE-EXHAUST-BAFFLE-SILENCER-48mm-CAN-BAFFLE-NEW-/350276156751?pt=UK_Motorcycle_Parts&hash=item518e15fd4f something like that but right size etc for your can .
