Jerry Wins...............According to the BMST records listing, we DID SET 4 RECORDS this year. Somehow I was able to get a tenth of a MPH ahead of the 2017 M-CG record set by the Triumph Trident at 136.62-mph

Motor Report:

Complete tear down shows the very beginning of wear on #2 Rod Bearing (about .001") Because the motor is at very close tolerances, we see piston to head RUBS at the edges of the chambers but no damage to the piston edges. The early editions of the Cycle-X cam and primary-chain tensioners show some wear with resultant 'chaff' in the oil sump and filter. The OEM primary chains are worn and will be replaced. The rods may have stretched a few thou so will be replaced along with new bearings. The .042 Copper head gasket now measures .040 so will be replaced along with new 0-rings. One cylinder-sleeve has a curious horizontal 'groove' about at the position of the top-ring at the bottom of the stroke. Otherwise, no other noticeable wear or damage was noticed. The bottoms of the pistons look like new. Parts will be sourced and the motor will be assembled next June for another trip to Bonneville in 2019

I haven't been able to follow this thread in detail, but suffice it to say, it is super cool. Keep on!

Thanks, Ron...............New Millennium bore of another set of jugs is already waiting for assembly.........Ken at Cycle X is getting the rest of the needed parts together for assembly next May-June when I return to Wisconsin. Any suggestions?

Me? Thanks but I'm so far out of the loop, I just look at the pretty pictures.

Stopped at the Mikuni booth while visiting the Barber Vintage Motorcycle Festival..........2 techs gave me SUDCO access for half-sizes of jets AND asked me why I did not add a bottle of NOS when they heard about my ram-air system. They claim I could simply spray with one nozzle into my air-chamber immediately after the filter........mixture would be uniform to each carb. Advice was to use jets at the upper-end of suitable size.

I could try the NOS in the Fuel Classes only...........tempting..........any advice???

Yeah .....get 2 barrels and piston sets ready..
Pm me an address, got pics for you from Miller in 09, the year you got hooked on Salt..
I sent them to (Dennis W , roaming the country in a motorhome..)..?.but they came back..

Jerry Rxman Griffin aka MuthaF'er · « **Reply #507 on:** October 08, 2018, 09:16:23 am »

Advice?? Me??

If NOS you'll totally blow away the Trident BUT maybe your rods too. That should be an expensive upgrade but hey, they will be lighter if you go Carrillos……. Will a bottle last the entire measured mile? That'd be 24 seconds at 150 or 20 seconds at 175

Save the bottle for the last runs after you set all the other records...…..

Already have one set of barrels and pistons as spares............was advised to use a single nozzle for modest amount of intermittent spray beginning about 2 seconds before hitting the measured mile and ending about midway through unless I don't plan on making another run

Off subject, but what’s the deal with these tires? They look to be either small dragster front runners shaved with a healthy flat area or are old LSR motorcycle tires.

Any idea?

More like new Micky Thompson Front Runners on 17-inch Astro-Lites?...........I think they are speed-rated at 200-mph or higher. I've been looking at them for my bike......especially on the front to get lower.

I think you are right👍 👏

Finally down-sized a few pics of some of the chassis alteration work.........

The extended swingarm.........

Old Scrambler · « **Reply #514 on:** October 17, 2018, 07:12:50 pm »

The new seat-tail section............those are SS rivets.........and that's Dave Murre at the English Wheel

Talk to dragracer, Frank, as he runs NOS in the 1/4 mile and he could give you insight on things to not do so you are not blowing up the motor in one pass.

Good luck with all that fun work you have underway!

A few more 'book-keeping' pics of bike; salt-flats pit-row; and crew..........

Old Scrambler · « **Reply #518 on:** October 20, 2018, 11:24:03 am »

Searched through my camera and found a few more pics related to the 2018 Bonneville experience..........

gschuld · « **Reply #519 on:** October 20, 2018, 02:18:29 pm »

Thx for the pics.

So you drove down in that van and pulled that trailer with the bike on it or do you only use that trailer on the salt?

George

Old Scrambler · « **Reply #520 on:** October 20, 2018, 04:47:10 pm »

The little trailer is only used on the salt and travels inside of my enclosed trailer with a lot of gear packed on it.

gschuld · « **Reply #521 on:** October 21, 2018, 06:20:17 am »

I figured as much. No worries about that trailer on the salt.😉

Old Scrambler · « **Reply #522 on:** October 21, 2018, 07:01:22 am »

It's borrowed from Dave Murre who insists I carry a spare wheel

..........otherwise it sits outdoors at his salvage yard and sleeps under the snow or tall grass.

gschuld · « **Reply #523 on:** October 21, 2018, 07:57:32 am »

Nice... I’m curious, is there a speed limit for support vehicles out there? Or just in the pits?

I understand it is 55mph on the access road at Speed Week anyway. Same for BMST?

Shhhhhh George! You'll get me busted
