My bike is in the shop and i have gone as far as a stage 3. I'm not out to be a drag bike but i want umpf, speed and acceleration. I think I have that with a stage .

What more would I get if I went to a Stage 4

from what I see Stage 4 from Stage 3 is only the throttle body.

What type of improvement would I see? I think it would only really be bottom end.

 

lots of stages.....i dont know what the hxll stages are. There is fast, faster and bad fast. haha

What are you having done to the bike. Please dont use the word stage.

 

The stages are according to the screaming eagle kits.

THIS IS NOT A SCREAMING EAGLE KIT BELOW. not yelling at you just making a point before someone says "that's not screaming eagle stuff...

Thinking stg 4 is adding a Blower to a stg3, which is BB kit, Hi lift Cams, Head porting, throttle body, crank welding, HD clutch and Comp.

For me ain't no way on a street bike..

Tim the Tool man wouldn't even do that.
Even a stg 3 bike if not put together and build right can be a bad choice for good road bike...

 

To really wake up a bike one needs port work done to the heads by a professional. Add in some matching cams that the head porter recommends, good fuel delivery, timing and exhaust to go with. Ask this question in the engine forum. Hillside cycle and prodrag will give you good ideas
