Hey my name is Steve Madison. I have been on the board forever but only lurk
now and then. I started a this project about 4 months ago to race at Barber's Ducstock event and Daytona following weekend.

My plan for the future is to race next year in Ahrma again
Barber was so fun and the bike to ride is so killer.

I hope you enjoy
I will do my best to post things in order and to show the process.

Thanks for looking

PICS WILL UPLOAD SOON
Steve

I will start with the motor. It was a 350 widecase from a scrambler.

I spared nothing when it came to the motor.

I put a Borgo hemi piston
We milled the head to fit the Mega cycle cam
Drilled & polished gearing.
Drilled Lightened clutch.
Polished inside and out.

Here is the motor in the frame and the motor back together

Also a pic of the custom plumbing we needed to do in order for oil to flow fast enough. When you build a 12 to 1 motor you need for oil to move. The original set up starves the motor of oil as it can't get thru the small banjo fittings that are OEM. Thus oil gets trapped in the valve covers trying to get thru.

If you are running the drains into the breather, how are you venting the crankcase?

Eldert · Nov 13th, 2011, 8:28 am

the drains are routed to the alternator outlet .
the crankcase vent is behind the top motormount

why did you leave that heavy kickstart shaft in there ?

Very nice work! Btw...how did you get the engine so clean, and the covers polished? My question is related to another running thread on engine polishing.

Thanks!

I thought alot about that and can still take it out if needed. Nice if it needs to
be kicked over as a last alternative to get it going. I use rollers at the track for the most part LOL.

The old tried and true way. Polishing wheel and compounds and time and more time. The best results however would be sending the parts to a professional polisher with massive wheels. For around $175 bucks and a week or so turn around you will have killer results. You can do it of course in a garage with a basic wheel but its dirty and time consuming. Some love it some hate it.

Here is a pic of the wheels. Polished and new spokes..Fitted with AM26 race compound rubber from Avon.

Here is the first time the shocks went on. They are 418 progressive springs that have the spring rate set for me and the bike.

Bad pic but very good looking shocks.
