Sure thing shorty! Lol. Progress the B plate number the other day was the metal one. The B friction also not available but I have sources......

Yep, that's me. Always short a dollar or a much needed part. Just rub it in my friend. Lol. I'll make something happen with the project bike before 2017 is over. It'll be good to move into 2018 with something to work from versus starting from scratch. I'm going to stay fairly local in 2018. Make as many Commerce races as possible so my brother can compete in the bike class.  The rest of the time I'll spend racing my drag car in nearby bracket races. I'll run a very limited Man Cup schedule. Likely just the first, and last race of 2018.😶

Back up bike coming along.

So fresh and so clean. Lol. Nice work Bill. Hope you won't have to race the back up and will be on the primary instead. I'm still accessing my status on racing my SOHC but I will enter a bike in street ET regardless. Either the old KZ or the ZX10 will be in the trailer.

November 2018 the lay down turbo should be ready.....at least I hope so. Billet block engine waiting on primary drive rt now....but I'm busy with the back up and primary ride. Installed Dyna S and EK DRZ2 530 drive chain today. 17/48 gearing,  might not need 5th, we'll see. Keeping it so I can back all original one day. Has some improvements like ignition, coils, drive chain and sprockets, SS allen heads etc.Even if primary bike ready I'll probably ride this in S ET.  We'll see how TestnTune goes. My new pitbike...Yamaha 1961 YDT-1, 250cc 2 stroke 1 carb, Y manifold. Elec start, the Patina Queen Rat Bike!

Looks like you're wrapping this one up. Good job. I rolled mine out of the trailer so I could get the top gas bike out because it was strapped down in the rear. I then pushed it back in the trailer. I'd better get busy. 2 days left :(

Roll on brother. Seems as if we're always trying to get something ready to race. Time is on your side right now. You could even be ready for some post season testing and maybe even make a few early season races prior to the Cup kickoff.

I'm going to do the best I can to drag myself in the shop tomorrow to start back working on the project F model. An old guy told me once that if you have a project, try to do at least one thing a day even when you don't feel like working. Eventually, it'll all get done.

Keep moving!!!

Yep,  going pull top end today,  check these out..... bottom one Cappallini,  the best I've seen so far, definitely will free up  some hp ,spins so freely top and bottom. Yes, it's pricey,  $270.00 for what you see, but I like it. Bill
The new one above it I'll let go, it's been assembled,  kmb69 was kind enough to help me out...$135.00 shipped 48 states

 Bill is that a collapsed O ring to left of cam roller.
When I wrecked my cam   I had a sticking guide..? When I pulled it apart both those brings had shrunk up, like 2 flat sides.. strange.
 I think good O rings stay soft  but I pulled a set off the oil jets recently, that were hard as ever , can't bend they break.

OK, an automatic can handle that? Turbine mod allowing higher rpm before take off too, right?
I have looked forward to see others using JMR Billet block, the result with various setups, cams etc.

Yes....there are others. I will dyno mine this spring. I really don't like the cam in it but that is a conversation for another time.
