Sandfrk33 Posted October 6, 2009 Report Posted October 6, 2009 What compression is it running? Do you use race fuel or pump gas? Quote
GNR101 Posted October 6, 2009 Report Posted October 6, 2009 totaly off subject... how do u like ur cpi pipes and.. the more timing u add the less ur bike will rev out. so adding timing will loose topend but lower the powerhit in the powerband.... Quote

stroking Posted October 7, 2009 Report Posted October 7, 2009 (edited) well i know someone that runs +14 on a cub with over 200psi and it runs 6.20's all day long he even tried lowering the comp. and the bike ran 6.40's so i'd say that timing and compression is one of thos secrets builder won't tell you,or lie about telling you too much will hurt your topend,and thats just not true. hers is what you do,take your bike to a drag strip and try +5 +7 +10 and see how it runs if it does not get faster with more timing i'll send you a $100 Edited October 7, 2009 by stroking Quote
