You let me know when that happens. I'm in Nj, and I want to see that.

prox site lists dimensions of everything but i dont know if the sizes listed are dead nuts on. they say 26mm for one of my pins but it measures alittle less with digital caliper. caliper could be off alittle and i dont have time to dig out the micrometer. if at all possible your probly better off getting a rod kit to get exact measurements

Sure will. I'll post video on youtube..... that thing should be a beast! Hoping for 90 HP with a 421 (top end depends on the deal I get.

Since you're in the Navy and I pay your salary, I expect to have some of these parts sent to me.. You know, out of the materials I am paying for that you're going to use.

If you pay his salary, then you most Definately pay my salary. In my 17 years, I have yet to see my military paycheck excluded from taxes unless in a deployed combat zone.

 

The marine corps is so damn broke that we don't even have a fucking wood shop let alone a mill.

I work on Submarines in guam. I have to tell them I can't do a job to get tooling replaced.

The light weight rotating assembly sounds good and and all, but that would be the same as running no flywheel mass. The crank weight doesn't hurt anything especially on a twin. The energy stored from the weight of one rod/crank wheel going up is put back into the rotating assembly when going down. It doesn't sound right I know, but I can provide a link to information on this from experimentation on the old RD 350s.

I've run both the small and big wheel 18mm crank and prefer the heavier big wheel.

 

There is a definite difference in how the bike comes out of the hole between the two.

 

I can't see how an extremely lightweight crank assembly would benefit anything.

bigger weight is gunna hold that torque, anybody ever add a bit of flywheel weight to thier motor? might work well on a big motor trail machine...some enduro riders used to add weight to mx bikes

I think you would be better off using AutoCAD to actually draw a new designed rod. Current rods available have weak points.

Talked with my machinist about doing more weight on the twister set up I'm starting for ice racing.

[Deadbeat]

that could be a killer set up for ice, how many cc is the twister gunna be?

[Jereme6655]

Dardy, 10mil 75mm small block....

Hoping to have Andy from Grand River Racing do the pipes since it'll be in a 450 chassis.

Been wanting to do this for 2 years but have been balls deep in remodeling my own place.

 

Jereme, most of out practice is on a private lake in Waterford or we go out on White Lake. There should be 2 races on white lake this year but the rest of the actual AMA d14 stuff is up in the air. Such piss poor planing. I might just run a couple

Races in Wisconsin and Ohio this year in stead though.

This is some old information, but a pretty good read. I can't believe I hadn't ran into that site before.
