didnt lonnie or brian put a 58 TB on his stock bike and it didnt make 1 hp difference?
why would you want to do this to a stock bike?
The pipe alone,tuned, would of shown the increase.ktap46 said:so i got the tbs on my bike and the D&D 2-1 and i have 114.78 rwh and 75.52 torque now. i went from stock v-modded exhaust topless race tuner. at 107.04 rwh and 73.29 torque
Of course they do,this was discussed long ago enjoy.http://1130cc.com/forums/showthread.php?t=12378&highlight=58mm+throttle+bodysJackflash said:Zippers claims a 5+ HP gain with the 58mm TB, which seems consistent with his gains. I doubt if its the pipe alone.
Did you modify your boots and stacks?ktap46 said:yeah i put the pipe on and noticed an increase. then a week later i installed the throttlebody's. and didnt notice much more. but i didnt tune it until i installed thetb's. i installed the tb's because i had them so i figured why not. cant hurt. its kinda a long story how i ended up with the tb's
Be very careful if your stacks are rubbing your air filter. If the filter has a wire mesh on the inside the stacks will wear through it and it will be inhaled by the engine.ktap46 said:no everything fit fine other than the air filter was a little harder to get on because of the larger diameter stacks.
What I had to do was bend and move the wiremesh so it wasn't touching the stack.o2man98 said:Use smaller diameter (stock) stacks bored to 58mm. Most of the aluminum stacks were meant for racing so they were not always concerned with fitting with the filter since most run without at the track.
That would work as well. I would cringe chopping on my new stacks.Vinny said:What I had to do was bend and move the wiremesh so it wasn't touching the stack.
With the billet stacks out there I have seen them modded where they would hit the filter.They just cut part of the bell off that interferred w/ the filter.This was on Badrod I.
