Wow, I'm impressed.  He learns quick for a guy that brags (in his online name) that he's an old guy.  Looks like a fun project, too.

like the build-also glad to see i,m not alone in the 'fill the workshop up to the roof' school of thought. grin

when we were kids,one of the local racers used  cub motors-we saw just about every trick he knew,and learned a few things.one that stuck with us was his pushrods-he used the stock ends and a very thin wall aluminium tube,before he assembled them he inserted timber dowels down the tubes to give rigidty-we,d never seen wood in such a high revving engine.sounds whacky but he won lots of club races.
all that work saved maybe 4 grams of weight,ANY advantage he had over the pack was a winning move as far as he was concerned.
best of luck with your bike,like all the one off stuff.

Its been a while and I've been away including a van trip to Yellowstone Park to visit our daughter in Idaho...........Dave Murre has been building the Cub in between customers and Al from the Advanced Landspeed shop has been helping by sponsoring parts at cost.  Anyhow...............IT RUNS........The motor was started on July 22nd and has only a minor oil leak...........I was away at a tractor show with one of my brothers........but Dave & Al phoned to let me know it was a success.

So.......we plan to make it to BUB and see how much fun can be had by going fast...slowly![/img]

Oil leak on a Triumph. Unheard of. Next thing you will say is that there is an electrical problem.

Day by day things progress...........lots of welding has now allowed the bike to roll off the bench for some testing.........Dave Murre, my all-around bike builder, thought that passing a 'can you lift it' test should be 1st on the list...........

I'll let Dave do the talking / showing about the electrics at BUB...........The 12V dry-cell battery is beneath the seat. The oil tank is an altered A-C bottle........the catch-tank was a formula bottle..........and the 21-inch wheels are from XL185 and XL350 Hondas but only the rear brake is active.  We are using the front speedo drive for early testing. The handgrips have Kevlar compound and the foot-shifter is now a rear-set on the left. The only secret is the source of the front fender........yet to be mounted.  The electric tach has a separate battery for memory.....and I still have to lose a few more pounds to squeeze into the borrowed leathers!

The first test ride went GREAT!..........A little fine tuning and shift-linkage to work on, but the Cub rolls straight and easily gets up to moderate speed.  Now for more time on the motor to set the rings and a couple of oil changes. Now if only I can find the decals I've been collecting for some decor.............Huh

old scrambler,

nice build.

what diameter and wall thickness aluminum tubing are you using
for the fuel tanks ? length ?

also curious as to the volume of 1 of them. looks like a gallon and a half or more per side.

need to do a tank for the new kneedragger. I'm done with in frame tanks.

Thanks for the nod...........The tank holds just under 2 gallons. It was made from a 5-inch diameter 'pipe' taken from an intake-stack off of a tractor-truck.  It was halved and expanded with a 2-inch flat-strap. The ends are 1/4-inch stock for strength because the tank is part of the frame geometry forming the upper head-stock brace. The size of the carburetor access tube was not known at first, but we needed to be sure the tank held 5-liters when finished. Dave Murre did the welding and fitment.......the cap is from Johnny Rocker in the UK.
