     '69 was before the change from AMA to SCTA classes and records.  No separate pushrod classes then so without digging for some old books I might or might not still have I'll bet it was a 2 stroke.

Ok, I get it. In fact the two smoke I was riding was legal per AMA and the guy who took me out with a fractional MPH more was not. We'd gone home, he changed classes. I wasn't worried because he had told me he had 6 gears still in the x-6 transmission. Unfortunately at tech, they didn't shift him through the gears as AMA only allowed 5.

I know in my heart that I legally jacked the record 10 mph, but it kinda stings, in my old age, that in never got in the books.

Thanks for the info,
I was thinking probably Suzuki X6, but then you never really said if that was what you were riding or not.  There was also the Kawasaki A1R 250 twin rotary valve 2 stroke that was fast. Still, a fantastic speed for a 250.  Maybe when I'm done with the BSA, I'll transplant something into with a little more power!

2-1/2 days before I leave Colorado for Bonneville and nothing left to do? I must have forgotten something.  Last year I didn't even get the motor started until Sunday at noon.  I added a front fender -- just something I had on the shelf that was made for a larger front wheel.  I don't think it will help my speed, but should keep some of the salt off the electrics and front of motor.  I also fabricated this belly pan, again to help keep the motor clean.  I have no idea if it's legal in open bike.  I can always claim that I need it to catch the inevitable oil leaks - - after all, it's British!  Side view shows extent of belly pan.  Last picture is as it sits to be presented to tech.  I'm quite sure they won't let me run that tailpiece in open bike class, but I have smaller side panels to replace it.  I'll let them tell me what is legal.

The bike looks good. I don't think the belly pan will be a problem. The zip ties holding it on might be though. I don't think the tail piece will fly either. I don't remember the exact wording.

Good luck at BUB.  Looking forward to tales of speed and records.

Thanks for the heads up!  I'll slot 4 of the holes and use hose clamps.  It will give the techs something to complain about, in any case.

OK,
So I changed the main jet and drained the gas out of the tank.  Then because I had the time, I went to Lowe's and bought 4 feet of 1-1/4" angle and a piece of 1/8" x 3" flat, and made some brackets to attach the starting rollers to a $20 hand truck.  Now my pit crew (of one) doesn't have to take the battery off and load them separately into the trailer every time I go for a run.  Sorry about the camera strap in front of the lens, but I think you can see the concept.

If I was really good, I could make a front fairing tomorrow to run in APS class, but it wouldn't be very pretty.

PEGGED!

I'm looking forward to the salt flats to cool off!  I took the following photos here in Lafayette, Colorado at 2:30 this afternoon.  The small one was reading 100 in the shade, until I moved it to the south side of my house.  I hope my speedometer looks like this at Bonneville.

We had a fantastic meet.  Record in 500 APG of 117.7, and with the tailpiece in APS-PG of 118.7 or so!  Here's photo of the happy camper with friends Russell, Ed, C.R., Sue, and Doug.  Noises  in motor today and slower, so will have to do tear-down to investigate.  I am at Miller raceway in Tooele for a few days.

Congrats on a successful meet KK.  What do think is making the hopefully not expensive noises?
