When will the final decision be made if the bike runs this year?

This is so monumental, I would drive across the continent to be there. The pyramid of humanity and work that supports this project is off the scale. As long as a mans dreams are alive, he really hasn't left us.

BTW, Jim has a soul mate that supports his dreams. That allows the rest of us to share in his.

I has been decided -as of this morning.
The event has been cancelled for this year due to poor salt conditions. What a downer.
I guess we will be ready for next year. Jim

Great work non the less Jim. That engine sounds so great.
Cheers,

The salt didn't want to give up the goods this year. Great work on the engine though! It sounds angry and ready to open up a can!!
 
Well we got 10,000 rpm, now to find a few more ponies.

I had an incredible time at Jims shop. We had our ups and downs but kept to the task of getting the bike ready for Bonneville.
The bummer of the entire trip was awaking the morning of the 17th to an email saying that the BMST was canceled due to salt conditions.
We continued on with hopes that we may be able to hit one of the other sanctioned events and got the bike on the dyno with the first run with long pipes pulling around 37hp and the power curve falling off around 7800 rpm.

Jim went to work programing the ignition and cutting the pipes down a few inches and got a run over 40hp. We called it a night and slept on it and came back the next morning fresh and ready to go.
The next day we were able to get about 44hp out of it but still have the power curve dropping off around 7,800 rpm.
We decided that it was time to go to the pipe length and size and ended up increase the diameter of the pipe and shortening it to a length that we all thought was ridiculous and what do you know. Power curve changed and we were once again going in the right direction.

We ran the bike up once again and this time we were able to gain a couple more HP...

Lets try one more thing, another increase in HP with the power curve running up to 9200 rpm. :)

I can say that we had a great time tuning the bike and every time we made a change we were able to see the increase and the HP on the dyno going in the right direction. Its not about the number on a dyno due to the fact that all dyno's record HP in their own way but the end result is to see gains when you are tuning on the same dyno and know that you are going the right direction.
I could not have done this without Jim and his expertise on building high horse power reliable Norton motors.
Cheers to you!

Impressive. That's a little over 94 hp/liter, which is pretty good for an old 2-valve pushrod twin. I'm sure you can find a bit more, but you're getting close to that point where its a lot of work for the small gains. Those pipes still look long to me for the rpm you're running at. I would have expected you to be somewhere around 20" - 22" if you're looking for a horsepower peak around 9500 rpm. No criticism intended. The real answer comes on the dyno, where you are, not from the armchair, where I am.

Those were the long small pipes we were breaking it in with. We are now at 1 5/8 X 18 inches.

I need to do some oil systems mods before I look for more power up high. jim

That should be interesting, given that the oil system is already pretty far from original. It's a whole different world making a Norton twin work at those rpm, isn't it? Didn't you develop a 750 that you buzzed up to around 9,000 rpm on your race bike, back in the day? Or is my memory failing me again?

I had a long stroke 750 that I turned to 9000. I learned how excess piston speed eats power and creates lots of heat. :lol:
 
Just saw the SCTA posting that they have also cancelled the World Finals event at Bonneville this year. That leaves the USFRA event in mid-September as the only remaining possibility. USFRA has said they will decide by this Saturday whether to run the event.

I made it out to Jim's last week to finish up tuning on Sir Eddy's Rocket and once again had the time of my life working towards the goal of getting the bike to Bonneville. Attached is a video of our final couple of days on the dyno searching for horses as Jim would say...

Thank you Jim!

Thinking of my father this weekend and looking forward to riding with him again this year at the Salt.
Jim and I have plans to make it out to the Bonneville Motorcycle Speed Trials on August 24th (my Birthday) to push the record up once again.

Jim has been working on the new motor and we are getting very anxious to get it back int he bike and back on the Dyno.

Happy Father's Day to all and a special Happy Father's Day to my Dad, looking forward to riding with you again in August Pops!

Anyone wanting to come out we can always use a hand around the pits, being part of the process and riding along in the truck is a bucket list that you will never forget. Watch out you may get hooked and have to return every year, I did...


 
I'm still planning to be there too, Paul. I'll see if I can't find a bottle of Stranahan's to bring along.

This is a great Happy Father’s Day tribute to your dad. I know how much that must have meant to you. My dad and I were on the Salt 1959-1961, when I was a youngster, and we raced together —bikes and cars—pretty much all the time up to when he passed in 1987, a short 32 years ago. I ended up racing 50 years, just quit a year or so ago, and I never forgot all the great times we had, and I just hope my 3 sons have half the memories he gave me! Happy Father’s Day to you!

Thank you! Always a day that brings back great memories, looking forward to running again, always brings my father to me every time I work on the bike.
 
Is it permitted to use methanol as fuel in Commandos at Bonneville ? That might mitigate the heat build-up problem which robs power and stuffs engines. It is the main reason I use it when racing. Plus you get a mild supercharging effect.
