So whats the standard jetting for a gk76a?


What jetting would you recommend for a tuned gk76a with full system and k&n (big ring)?


Dyno center dont want to touch mine without a base setting...

Is the bike running? im surprised they wont run it as the dyno will show the fueling straight off and you can alter the jetting from the findings.
If it runs and revs clean at the moment it will be close, the last bike i worked on that had a k&n needed the needle lifting one place but did not run any more air at the top end so main jet was as stock.
