Okay. But I guess I now have to admit I've been doing this wrong in my F model for over 20 years now.My logic was just the opposite of what you described above. Same chains, same orientation, hundreds of hard launches, 1/8th and 1/4 mile passes. I'd probably be wise to replace the chains when I tear it down this time and stagger them like everyone else.

If you had been making the kind of power brother Bear makes, you probably would have figured it out!

Need to bump that engine up a bit, Frank!

Your nitrous ought to do the trick!

Yes you can.... I fell asleep....but here's the countershaft assembly with new big gears, damn, they much more dense, 5th counter, dog gear 30 grams more, 2nd , 50 grams more! Engagement on all 4 dogs is perfect both ways, on to the mainshaft and primary. I like it! K.

Yep, the stock gears are castings or forgings and are not as "dense" as the billet gears. Plus the extra dog on 5th and the engagement slots don't go all the way through on 2nd. They appear to be pretty heavy duty!

OK, I'll spill the beans. Bear (Brian) was kind enough to send a set of his heavy duty gears to me a while back so we could reverse engineer them. BIG KUDOS AND THANKS TO BRIAN! Brian and the guys down under had to develop and use these HD gear sets for some time because their motors are pumping some serious ponies!

However, prior to us having our gear cutting skills online, Yamiya750 started offering these sets off the shelf. They are not cheap but they are very high quality billet gear sets made in Japan. Yamiya750 has usually been keeping 1 set of these in stock for immediate shipment. Don't despair if they show to be out of stock because they usually restock in about 2 weeks.

Bill will be the first one I know to put them to the test under drag racing conditions. I have inspected these gear sets closely and I am very confident they will perform.

Holy smokes those are sweet. If I beat my gears to death road racing, these will go in next time around.

I'm hoping one day to make a bit more power on the red F model, but not as much as Bear or with nitrous. I do intend to get help from the bottle on the new project F model though. I'll be testing the Cycle Ex rods to the limit on this one.

Yeah, those are sweet and not for the faint of wallet $640.

Keith do you know how these would work in a F tranny?

1. Yep, but a lot cheaper than a busted tranny at the event you're counting on winning!

2. After giving Billie a false alarm last night regarding same, and looking closer at my set, pretty sure they can be used in a F trans. You may have to put an extra thrust washer behind the 2nd gear but I will have to confirm that.

I wasn't sure about the tooth count/ratio thing?? It mentioned K but didn't mention teeth.

$640 can be REAL cheap in time AND money.

PeWe · « **Reply #182 on:** February 27, 2018, 09:55:16 PM »

It can cost a lot more if not order a set.

Bill/BentON Racing · « **Reply #183 on:** February 27, 2018, 10:16:05 PM »

I agree, they should work on a F model also. F's with bushings in the gears have the 25mm thrust washers built on the bushing. So you'd have to add the washer, usallly requires a little filing/dressing of inside of washer to slide easily on the F shaft, at least that's what I encountered on the last F I put undercut trans gears in. Yippee Kai Yeah, lookee here Murphy...really time for billet block now! This BE is stout! Man it spins so easily....Im getting excited about this one! Lol, Bill

Why you no got protectors on those rods while you spinnin stuff around?

Bill/BentON Racing · « **Reply #185 on:** February 28, 2018, 07:43:12 AM »

It was another test y all passed.

Didn't turn the motor over. Just grabbed clutch basket to see how easy it turned.

Next time you will see the rod protectors,laying next to motor out of sight

Jerry Rxman Griffin aka MuthaF'er · « **Reply #186 on:** February 28, 2018, 10:42:49 AM »

Well hell Bill, you forgot part of the starter too

Not a S-ET bike?

Now paint the cylinders silver, black head and chrome cover. I like your color choice so far

Billy needs to polish out that whole billet JMR cylinder😳. Then painted head, then polished cam cover. Go big Mr. Bling👍. Blind us with shiny stuff😁

The JMR cylinder look really good as it is from Mike. Same finish on the rest of the engine will shine fine!
I could not resist to add some photos of JMR billet block. Well worth to admire.

kmb69 · « **Reply #189 on:** February 28, 2018, 03:08:56 PM »

Definitely ARTWORK!

gschuld · « **Reply #190 on:** February 28, 2018, 03:14:09 PM »

Never get tired of admiring that cylinder...

dragracer · « **Reply #191 on:** February 28, 2018, 04:30:48 PM »

Looks good Bill. Keep it going. A little over 30 days and counting down.

Thanks, pulled the Chapman engine down, a real big disappointment. This one however pretty nice. It's the one from Tennessee a couple years back. It's cool. The Chapman engine, well more on it later, I got taken on that one! One in pics measured 72.75, had CR31s, ported head, big intakes, RC Golden rods piston's machine like later Cobra motors, not drilled skirts! Regrind cam, looks like a 327. More later.

RC block?

BPellerine · « **Reply #194 on:** March 09, 2018, 07:06:32 AM »

ko cam cover!

Bill/BentON Racing · « **Reply #195 on:** March 09, 2018, 07:00:03 PM »

Yes RC block and waffle cam cover with cam tower supports

T1m32sh1n3 · « **Reply #196 on:** March 10, 2018, 07:31:49 AM »

What makes it a waffle cam cover?

gschuld · « **Reply #197 on:** March 10, 2018, 09:17:31 AM »

Breakfast time and some maple syrup😁

George

Bill/BentON Racing · « **Reply #198 on:** March 10, 2018, 09:39:37 AM »
