250 enticer upgrades

[Shaggie]

My last 250 enticer was a 77, I added a handle bar gauge pod, and took WAY too much off the head.
I pulled about 63mph.
This "new" one I'd like to gain about 10mph over stock and not lose any of the bottom end grunt.
has anyone built a pipe for it?
will a mikuni be an improvment?
has anyone done anything to the ports?
a thinner base gasket?
yes, I know to gain speed I should go on a diet, that is a last resort.
if anyone has any ideas please let me know.
Thanks, Shaggie

P.S.
The speedometer gos up to 100mph. HA! That might be too much work.

man did you regear and reclutch to go 63 mph would love to make my brother inlaws et 250 go that fast also how much is to much to tke off the head?

I think all I did was have the head shaved.
and lubed everything, ran the track just a little looser than a larger machine.

well i do not know the difference in gearing but our 1979 with a powerblock clutch passes 340's on the lake. it is a dog off of the line but it moves pretty good once rolling. i did cheat though and put the track on backwards. boy does it hook up now.
