looking to increase power.

ok, since i have went from my 250 to my 300 top end, i cant really decide if i have gained or lost power. i thought that it would pull the tire off the ground no problem hitting third, but now it seems reluctant (cant really remember, i get used to power fast)
the most noticable thing that changed with the 300 kit was the powerband. before, it was a very smooth, VERY wide powerband. before, it never really HIT the powerband as it seemsed to always be in the powerband. now it seems narrower and it seems to HIT.

i tried to do a compression check, and i got about 150 lbs, but i dont think i had the hose tight on the plug hole.

what is the highest compression range i can run on pump gas? i thought it was around 190, but im not sure. i dont want it right on the edge, but about 7 to 10 psi below the race gas threshold.
if i have this done, i will probably have the jug ported for aggressive trail/dune riding as well.
just wondering if i should have it ported by PR racing (local shop) or send the jugout to someone? any suggestions? anyone dealt with that FLOTEK company run through E2S site? i want a good port job without breaking the bank.

Race gas(even blended)is cheap insurance... Cranking pressure is not a very good indicator of fuel requirement... There is too many variables involved for it to be accurate...

hmmm...my 300 was always powerfull...what kind of pipe do you have? a pipe is the biggest factor on a 2 stroke if you have a dg, forget about it being smooth.. If you luck out get a old custom sectional, I have a jemco and mine ripped like there was no tomorow, also what kind of reeds are you running?? and are you running that big carb? with that big carb you will loose some bottom end, dont go and start milling things to gain compresion, these motors run stupid hot as it is, dont ened to increase that, port work would help but you need a place that is flamialar with these old engines as well to beniefiet from it.

its a DG, and yes, before the 300, the powerband was essentially everywhere. it never hit, and ittook off like a bat outta hell.i cant really compare because its been so long since i rode it with the 250 top end.

yes, i am running a 38mm keihin. yes, it is fast as crap, dont get me wrong. I just adjust to things way too easily, been riding anything i can get on since i was 4.

i might get it ported next year sometime, but il just going to leave it for now. tired of not riding it due to work lol.
