How about the 81 srx 440 with 44 and why did bender put 44 on his 540 s if there was no power gain. I am looking for a base line set up for a 81 440 with 40mm carbs and there specs for a Polaris wide belt overdrive setup Richards perfomance sold back in day I trying to set a 81 srx for speed runs on...

Does any one have there old clutch spec or 44 Carb set up they use to sell it would be nice to have all the testing they did 30years ago before its lost forever.

Does any one know if the 8r9 updated cdi have a rev limter at 9000 rpm
