Tomahawk Cup race bike

Don’t know what the Tomahawk Cup is? read this! – http://www.mopedarmy.com/forums/read.php?1,3527560,page=1

These are the classes as they were hashed out and as they currently stand –

Stockish Class
=============
– No custom frames
– Pedals or Kickstart
– Stock Cylinder ONLY
– 15 mm carb limit
– Aftermarket pipe allowed
– Variated bikes allowed with no launch lever
– Any factory chassis or engine parts can be swapped to build a stock frankenbike.

Non-Variated Class
==========
– < 75cc Kits air cooled
– No carb limit
– 1 and 2 speeds
– Moped H20 < 50cc kits

Variated Class
==========
– < 75cc kits air cooled
– Bo carb limit
– Moped H20 < 50cc kits

Unlimited Class
===========
– < 99cc kits

While I have a billion projects, a few of which might be fun in some of those classes, I decided to do a Puch E50 build for the non-variated class. I have already done the crazy, complicated, weirdo concept super race bike thing for the Polini Cup all those years ago and was totally burned when no one showed up to race and the series got canceled, so I decided I would build something simple, easy and, most importantly, CHEAP to go racing with. Worst case scenario – this race circuit bombs like the Polini Cup and I have a super rad Maxi to rip around on that didn’t cost a bunch of money and end up too much a headache to put on the street (ala VX4).

Chris Paz hooked me up with a frame. Well, most of a frame. It’s going to need some stuff welded back on, namely some shock mounts, but it’s free and a rad platform to build on!

I may take his work further and cut the seatpost part of the frame off and just build something out of tube steel to sit on, I’m not sure yet.

Other parts I already have laying around are a set of E50 cases, a 17″ disk brake front wheel, a couple different french bike pipes to choose from (Doppler and Doppler clones, I think? Not much of a choice really.), and this thingy-

KTM 50 CDI, same setup I’ve been running on ciaociao for yeeeears. Mr. Naz up in Seattle built this for someone forever ago and I ended up with it.

It’ll be perfect!

My plan for the engine build is going to be a heavily ported Gila on that 77 stuffy crank with the 77 Super Clutch. I’m going to use a pull start, so I’ll ditch the stock starting bits and cut the starting plate off the clutch to lighten it up some. I’ve also got some clutch bell mods in store, as well as lightening the main gear. I’m going to balance all those bits too while I’m at it.
I’ll probably run one of the 24mm carbs I have laying around.

The new Garage will be out soon and I’ll be documenting the build over there, but I’ll link it up over here too when ever I have updates.

This should be a fun build! I can’t wait to get back on the track!
