well my motor has a cam, which one i dont know, but i know i have vthunder adjustable pushrods, and a S&S Super E carb plus vance and hines longshots. motor has enough power just figured if i had to to a re-ring and hone it would be the time to just go with a cylinder piston kit.

 

Can you ask last owner what he knows about the changes ? If you want any hp to show change exhaust, Khrome Werks system, D&D, Thunderheader, Supertrapp. The longshots are not even a good exhaust for hp and tq.This alone would make up more than the BIG BORE kit. Check your compression and bleed down ,Stock should be around 125LBS and 12% bleed with good cylinders. Try to do a couple dyno runs for W.O.T. and part throttle with A/F mix on both in 4th gear. Try to be between 13.4 and 13.8a/f. Look at night riders site and cyclerama's site for dyno runs and parts used . That my help guess what's in there. Would i spend 1000 bucks for a BB NOT till the exhaust was atleast changed Any thing more than a ev27 or woods 6 will start to need springs and head work with more comp. You could look in your intake and exhaust ports to see if it looks like head work has been done,flowed guides changed to bronze. If the ignition is stock it has not had much done to it.

 

well i found out that i got some bad gas, made it smoke white when i rapped on the acceleration at idle a couple times. filled it up with good gas and its fine. didnt really want to to anything to it and seems now i dont have to.
