dirtynidge Posted March 31, 2010 You would normally have to re-jet to get the most from them, try it first and see how it feels. May need to go one or two main jets sizes leaner and a maybe leaner needle. Use the jetting thread in FAQ at the top of the page if you are unsure. Share this post Link to post Share on other sites
