levy1 Posted October 18, 2005 OK, following all your instructions I am adding a 13 tooth front sprocket, cut out the screen in the exhaust pipe, removed the stock air box and added a pod filter. Where do I start with the jetting. Stock is 62. All I could order from the dealer is a 65 main. Will this be enough? Do I need to change the pilot? If needed where can I buy bigger jets?

filthyboatguy Posted October 18, 2005 Stock is 62, it is fine. Put the clip on the needle in the middle. Enjoy. Share this post Link to post Share on other sites
indy16 Posted October 18, 2005 I did the same mods on my sons 70 and just moved the clip and turned the fuel/air screw 1/4 turn. No jets changed. Share this post Link to post Share on other sites
