A shovel is an acceptable excuse. M/G 500 records are pretty stiff but if you have a look at the M/BG and MPS/BG records are very attainable. Hope to see it out some time in the near future.

my plan is to go M/P or G the first year, get my feel for it...long term i want to build a MPS/BG or BF 500...read a lot but not sure if the gs500 would be a wise choice powerplant wise for that endeavor...and if im bike shopping to build MPS/BG i might go a different size ro something but yea the MPS/BG record looks very do-able...i've talked about it in the past with my pops (aerospace engineer) and he said he'd be game to help me with the streamlining part

Oh how I love you speed demons....you guys build the most functional stuff out of thin air. Outrageous craftsmanship.

Unlike me who is a hack and a caveman.

Good luck next week and too bad bonnie don't have a black line anymore...keep it between the cones!

We plan to run ECTA at Ohio Mile the beginning of June,then there's the LSR in Maine. Both are paved.
I built the engine more for durability than ultimate power.
How about you? What going on inside that Pre Unit? I know race guys don't want to reveal any secrets

Good luck at Bonneville, maybe i'll see you.
I just finished the bike, we will be at the lake bed later today to go through inspection. So far i do not think i have any secrets, just some experimental mods. Not quite sure yet if they will turn into secrets, will let you know

We had a great weekend, The freshly build pre unit iron head motor achieved a official speed of 124mph.
There are a few things i need to change but overall it's fine and it seems like the engine still has some more juice in it. We will see by the next race in june.

And my new alloy clutch set-up worked extremely well, (Thanks Druff from Franz & Grubb Engine). If you're building any high perf triumph stuff give this guy a call fagengine.com

Congrats Alp!!! A great number for the first time out. And nothing broke. A bonus!! Sorry I didn't make it but I am still waiting for the OK on the sidecar wheel. No point in hauling and be told you can't run. June isn't that far away.

Thank you Bill, I was trying to get a fourth run when you saw us.

I am more than happy about the the 126.78mph @ 5462ft da this bike achieved, but there are some issues i need to take care of. When this bike came out on to the market in 1950 it had less than 30hp on the rear wheel, and now with the 63 year old original frame I do not feel very comfortable. But this is why the modified vintage class records are so tough. Especially when you're competing against 1000cc indian and harleys in the 650cc class!

Eric Vaughn's 1000 cc Indian was a particularly fast one. but look at it this way. Your second or third time out (can't remember) and you are only 7 mph short of the record. IIRC he set that record with a pretty good tailwind. Oct or Nov. meets sometimes have really good tailwinds that can be worth 10-12 mph.

I was doing patrol about a third of the way up the course. Your engine sounded strong the whole way. A little help from Mother Nature and a strong engine can work wonders.

If you run the std frame, why the modified class?

Alp has done a series of mods to the rest of the bike that puts him in modified. But at El Mirage there is no modified class so he has to run in A which is special construction. A bit of a handicap but that's the way it is. Alp is a very skilled buildere and I have no doubt he will eventually find the extra bit of speed needed. It only took ten years to get my first record there LOL! My Norton runs a bone stock featherbed frame and is in special construction.
