You're doing it the wrong way round. If you stick a new can on it it will most likely upset the fuelling (not as much as a full system but it will still have an effect). So if you tinker with the carbs now, then change the can, you could be back to square 1. Put the can on, stick it on a dyno again, THEN adjust the needles if required. Always do a dyno run AFTER you've modded any part of the inlet / exhaust combo.banner001 wrote:, ill get him to drop the main jets slightly, that should richen it up a bit.

Have you been in the engine to check valve clearances? Have the carbs been balanced? Even with a worn chain 54bhp is pretty dire and suggests it could do with a damn good service.
