[RagunCajun]

Drag poring imo blows cept for drag racing only. NO low and mid but nuts on topend. I rode a shee with a drag ported little cub, it sucked to play around with.

with the 350 air cooled engine your building, how are you going that big? the biggest air cooled 250r big bore I have heard of is a 330. are you going with a stroker crank or a custom sleeve? That thing ought to rip once denny ports it. Keep us posted i'd like to see another one of his drag bikes run, cause he's probably getting my new drag motor.

how do the air cooled 250's handle?

The 350r is actually only going to be around 330cc's and it will be based off a 250r bottom end with a 4mm stroker crank modified to accept an odyssey 350 rod then I'll have the cases bored to accept a bigger sleeve diameter because I'll be running a 350 odyssey cylinder, head and piston as well. heres a pic of the cylinder.

I also have a straight fined head to go on it.

What cylinder is that on the left? They both look slightly ported. The Odyssey top end bolt on or case moddifications needed? That 350 bike should be really bad ass. What kind of pipe are you getting for it. IMO when it comes to custom pipes Shearer would be the best.

The cylinder on the left looks to be a air cooled 250r cylinder.
those odyssey's where fast machines back in the day.

yea I figured it was a 250r air cooled but I wasnt sure if it was his 300r kit or not. because his 300r kit is not ported as far as I know. that one is clearly touched up in the port area.

With 18" rear's they handle great.

The cylinder on the left is a 300r kit I picked up on ebay for cheap it's the one I'm going to run next season and have Denny port it, my current 300r kit I bought N.O.S so I don't want to modify it. Also the odyssey cylinder is unported.
