Hey guys,
I’m close to installing a new exhaust system. Stainless silencers with a baffle in each. I have a hi flo filter too.
Now, can I just adjust the carbs to run well or will I need to re-jet? If I need to re-jet, what kit should I buy and where can I find it?
Also, if I re-jet, will the petcock allow enough fuel through to keep up with the higher fuel demand from the engine?
Thanks!!

no matter what you do to the bike you will get all the fuel you need from the tank tap if the filter is clean .re jetting the carbs is a guessing game .try the bike as is if running lean go up a size if still go up more its all trial and error

Thanks mark.
I may need an extension pipe between the downpipes and the new silencers. Perhaps 200mm. Where can I get something like that? I’ve searched and searched

I’ve seen loads of those myself. Unfortunately straight lengths of pipe aren’t very common it seems.

Amazing! Thank you. Can you tell me the diameter of the downpipes for the CB250N? Those pipes are 35mm

Everyone here has been unbelievable helpful. I’m finally getting the bike into shape and a lot of advice from this forum has allowed me to do that. Thanks so much everyone.
