Check out Kenny Cummings leading into the 1st turn with the JS Lightweight pistons & longer rods.

The event was at the New Hampshire Motor Speedway for the Vintage Celebration, with USCRA as the race org. The class was Eurocup

- it's a catchall of European/Brit bikes up to 1000cc. Kenny won the class by about 20 seconds, in front of Triumph #600

Kenny says that the bike is smoother and reves more quickly with the lightweight pistons.

Couldn't have had anything to do with the virtually standard Fullauto Technologies head ya think? I must say though Jim, that I really crave a set of your rods and pistons.

I'm sure he'd take a head in swap...
 
Yesterday I received a box from Jim Schmidt, steel rods, forged pistions and "gapless" rings. Today they go with the rotating parts to be balanced and clearanced at Lindskog, the cases are on their way to CNW for the breather mod, new cam bushes and cleaning. I'm very excited by the prospect of spending time in the uppoer end of the tach without worring about grenading. I promise to share this build with the forum, sorry I missed the transmission, but SwooshDave has already given us the difinitive pictorial on that.

Thanks Jim,

Yes, I took the new motor out to Loudon (NHMS) for a shakedown weekend before the big upcoming AHRMA rounds, and got the win in Eurocup.
The motor felt smooth as can be. The new JS rod/piston combo really made it run sweet. I'm balanced at 78% for my Seeley, which is a little higher than Jim suggested, but I have to say I never once thought about buzzing. I was able to reel in all the other bikes with no problem.

I'm doing some dyno runs to try some different things with the new Fullauto head to see what we can squeeze out of it, but it already feels like a winner. Wait... it already *IS* a winner.
 
Kenny, just for grins, what would you say the ballpark price for a drop-in race engine similar to yours would end up being?

Also, I'm sure I read it if you posted it, but what were the dyno HP numbers up to, and have you done anything else to it since your last dyno run?

I don't think there's an easy way I can answer that question. I've had a lot of stuff that I've accumulated over time in this new motor, as well as support from Jim Schmidt, Fullauto, Colorado Norton Works/Jim Comstock, and certainly Ken Canaga. The time alone that goes into working up a motor must be added into the total. If you are serious about tuning, compression, squish, valve angles, etc, there really is no off-the-shelf price for it all.

I don't advertise numbers - there are rival eyes watching this board.
 
No worries.

I'm just wild guessing that to have a bike that could beat you (don't even get started on the rider), one would probably have to dump $20K into it, and it better pump out significantly higher than 70 HP...
 
Naw, $20K wouldn't get you 1/2 way to what Kenny wins on.
To actually race their machine, costs a few more bikes worth.

To best their extreme machines with another Commando like bike
requires double that in time and money plus cheating completely
on any limiting race class rules
and leaving anything really Norton at home.

Costs even more to travel to the darned races when you live 1,200 miles from the nearest track!
