MOPED ARMY

i've got a really good one but no scanner. High 40's with great torque on 15 bing, probably would be doing 50 on a bigger carb.

i'll upload the photos in a second here.

Go find Jamie Leslie, I built 2 metra 65s for him before I left, he may have one apart you can look at.

haha, thats actually the exact same port map i have, i think... mine is measured from the top edge for calculating it in degrees....

Thanks strongar!

16-45 on that setup. 12000 rpm.

god damn. maybe i'll try that map on my trashed cylinder and have somebody re-bore it

Anyone raise and lower the ports on this shit?

proma circuit pipe 3 inches chopped of end before silencer

19mm phbg 40 idle 104 main jet

gearing 17 - 36

murrey swing-arm 2.50 back tire

stock clutch - tension about half way screwed out

3 shoe ran about the same

piston even with bottom of exhaust port (you have to add one more small gasket

case matched - treats race crank bearing seals..

slight bog if you full throttle from start

no bog if you give it a second or two and be easy from start

takes a minute to get going (gearing ?)

low mid 50's

any suggestions on how to make this take of with out bogging and rip from the start?

i figure if i change gearing it would bring the low end back some but the slight bog at first gets me, i have been checking for leaks and all that. i have built a few bikes and gone through most of the normal obvious first issues

i have the needle on down from top

that main is big i have a 65 mrtra with a 21 on it ported to hell and i am only running a 86 main and a 36 ideal so you might have an air leek or it is real real cold where you ride

lower your idal speed tell it just barely runs on the stand have the e50 hot then start spraying with carb cleaner i know you think you dont have an air leek but i have had like 10 peds come over with the same problem to big of a main jet and a bogy top end and still a slightly lean plug and it ends up being some small air leek

Not saying this is the method you used or anything... This was sold on here a couple months ago and i found it intriguing.

And the piston is skirted differently to allow for the last little bit of exhaust or intake duration to leave or enter the cylinder, depending on which side of the piston it is on.

The extra metal spacer raises the kit to sit where I wanted it.

And the piston was trimmed up for longer intake duration for mach ten speed.
