Mark Weixeldorfer's Holiday Honda/Nicholson Racing Products Barker machine built/Keith Lynas maintained methanol burning 90/180. Actually, this bike had a 62mm piston fit before its last race in 1980 at Speedway 117, so its larger than 180. This bike has been sitting on its grab bar since 1980, until 2 weeks ago.

I am the current caretaker and will be future owner of this machine. This bike will be on display at the CALVMX 3 wheeler race this weekend.

Quick rundown of known mods:
-Hurst Airheart front disk brake setup
-custom front hub
-gold mitchell 3 bolt wheels
-custom forks built by a gent in National City, Ca. the name escapes me at the moment - Iron Horse i think
-chromoly Nicholson racing frame. extended w/lowered motor
-Barker machine built 61mm stroker motor with hi/lo cutout, clutch conversion.
-custom intake mated to single carb from set of 4 off of a honda 4 cylinder. set up for methanol. size unknown.
-custom exhaust. large diameter straight pipe
-Renthal bars
-twist throttle

i apologize for not being able to recall who made some of the custom stuff. The people who made these items were not big name companies and when Mark told me their names, i didnt recognize most of them. They were machinists and engineers working out of their shops and garages. This bike truly is a tribute to the dedication and innovation that happened in those days.

Awesome!-Whats the thingy on the underside of the motor where the exhaust valve/rocker cap is? Some type of heat sink/oil cooler or what?

Paul truly a great find! That is definitely where it all started. Most people don't know or appreciate how trick those bikes are. They were one off fire breathing beast full of innovative parts. Not to mention a blast to race. The carb is from a CB750. 26 or 28mm. That is what most ran especially set up for methanol. I like the lower valve cover cap. Looks to serve as an oil cooler. I'm Diggin' he raced with the Grab-Ons. Great Piece of ATC Racing History! Thanks for Posting. :drool:

Ever since I saw this post this morning I couldn't stop thinkin about it. Can't wait for more pics! You have something very special there. Glad to see it came into someone's possession that will appreciate it for what it actually is! In my opinion this is the absolute best peice of early race history that I have ever came across and seen to date.

The throttle is only being 'blipped.' I was warned by mark that the motor is never to be really revved unloaded as it's extremely easy to over rev this motor

Manbearpig, you must be a collector or someone very sharp! Great to hear you'll grab this and maybe just some light maintenance and slight restoration and your good. Amazing the 90's they built back then.

That IS The history we would all love to study!!

Great for you bud!

Mark is a lanky guy and makes that trike look small. He was also a great rider. I think he was already 27-28 when he was in the prime times of three wheel racing.
