Exhaust and minor mods versus cylinder head change out?

[IMFASTTOO]

From what I've seen posted on here you should be able to get to the 150 - 160 HP range with a good exhaust (Reband or Carpenter type system), an upgraded intake, and a good dyno tune. Don't know that I've seen anyone go to 170 HP without some engine mods

weve seen 175 + hp with just a pipe no head work

maybe but I do not need all that and my cost is way lower so far that is enough for me plus carp is on the other side of the continent not too practical .

whats the cost and what do you have ?

 

[IMFASTTOO]

Thanks Steel. Impressive numbers. Do any of these dyno runs show power readings starting as low as 1500 or 2000 rpm ?

THATS cruising range and bob tunes that area for smoooothness and gas mileage LOL 40+MPG

Sounds like the SJ2 kit

YES the SJ2 kit

POST the dyno chart for your bike to compare

i wish I could get a dyno for mine but no one in my vicinity so far. I think probably what I'm looking for is more low end grunt or torque. Does any one have a dyno chart for a stock roadster to compare it too?

what the stock engine has all you can use so then leave it stock and save your money If you want to beat other rockets or anything else then you can modify the engine to produce HP where you need it to improve performance and win races

thanks, that's helpful. So the dyno doesn't really start indicating until around 3,500rpm anyway. I didn't realize that.
