Carb settings for a 4 into 1 exhaust.

<< < (2/2)

simonster:
To be honest I'm not sure what make the pipes is. The I bought the bike as an engine in a frame with wheels and all the other components came in a box and that included the exhaust. It has been shortened I would estimate by 4-5 inch. I couldn't see any markings to identify the make or even be sure it has been run on the bike and the pipes have now been fully wrapped, premature I know! The bike looks like it has been raced in the past so I had assumed the carb settings would have been altered to suit that purpose. However, the jets are standard but not sure abt the needle. I have attached a pic in case anyone recognises the make of the pipes, long shot i guess.

early Harris?

just about all of this style of pipe tend to have a hole mid range with perhaps some more at the top- just down to lack of volume and pipe lengths paying more attention to style than performance

a standard full throttle plug check  (flat out hit the kill switch and coast to a stop ) will at least check that the mains are not lean enough to damage anything  (unlikely)

you may just have to live with mid range- especially if you are not planning an air box- just describe it as "character"!

simonster:
Cheers Motad, that advice does help and reassures me to stick with these settings and only alter things if problems are evident.
