OS 2060 is THE way to go on the speed. I think it runs best with the 8mm venturi. Just rebuilt mine and put a eb modded head button and back plate. Ed says i should run the 9mm venturi but winter set in here in pa so i haven't had a chance to try. These motors have great power everywhere and rev better and pull harder than anything i've seen. JX ninja pretty identical. Get the right pipe on it. You can still get a eb mods 2041 on ebay if you find the 2060 too salty. Work with your clutch. You may have to stagger the spring tension. Look into answer-rcusa clutch set. Comes with shoes and 3 sets of springs, 0.9, 1.0 and 1.1 for 19 bucks.
