Hey nekro, been a long time!
Good to see you're still around.
I ran across a thread in a different forum that was showing 45HP dyno runs for a stock ported 250 with similar bolt on mods to yours (boyeson reeds, FMF).
Can't find the dyno chart, but 44.9HP was the max HP.
Suzuki - Does anybody have any LT250r / quadracer dyno charts!!! - I am trying to tune my motor and I want to see at what RPM
