...yes indeed. It's the very type that sat on one of  "Burt Munro's" bikes in the "Worlds Fastest Indian" movie.
One nifty feature is a tiny LED lamp on the trigger take-up ( the small square aluminum box)
that lights up at the point of ignition. Makes adjusting the timing so much easier.

Yep; the sound of me going "AAAAAUUURGH",
after I found a tiny crack in the oil-tank.
Will weld it up tonight and later seal the tank with a two-pack sealer, just to be safe.

Rocky: how's going with the liner Huh
Is the engine ready ?

Lars,
   I got the new moly rings for engine, still need to sort out some extra Bonneville valve springs for the valves, the heads are being machined , I need to check with Ed, the machinist as his wife is in hospital at the same time. The Lakeview fellows are geared up to reproduce the factory Daytona heads I have with a smaller valve chamber as a billet head if I can create the drawing in 3-D CAD solid works.. Engine is apart and ready to check cam timing of 4 lobes as I suspect I have the front cam jumped one tooth advanced. I will be out of town working this week, but should be ready to start assembling when I return over the weekend. The liner engine will be ready, if something comes up I have a back up plan that will involne an engine size change for BUB.

Hi !...I'm still here.

Busy fighting the demons that keep popping out of the machine.

It's like a crazy dance where you take one step forward and two steps back and one one step forward and two steps back .....etc.etc.etc.





Rocky ! Glad to hear you're making progress !

..nope ( not that I know of, anyway ).

Just a load of things that are acting up:
a starter that won't work, a carb that gives me grief, some other stuff...blahblah......the clock is ticking !

I'm working on it.

Lars, did you seal your tanks yet? Over the years I've tried several brands, but I recommend this one 200%, it's superb and sets like rock overnight, as do any leftovers in the can sad
I always do both my fuel tank and oil tank on eveything I make. Mask off any threads! It's called POR15 and is single pack, you can get it from Frost Products http://www.frost.co.uk/item_detail.asp?productID=8232&frostProductName=Fuel+Tank+Sealer+(US+Quart%2C+946ml)++&frostCat=&frostSubCat=&CatID=28&SubCatID=

Thanks Chris for the tip !
I already bought a somewhat similar single-pack product for the fuel-tank , but haven't 'done' it yet.
Methanol will eat most things two-pack , but for the oil-tank I'm going for
a two-pack product , mostly because several friends has used it successfully ( forgot the brand name )

I,m glad the clock is ticking cause that means I am still on the right side of the green grass and I am in  control.

Ha ha , I guess you're right !!!



Now back to work....the clock is spinning

Lars, will your oil have some methanol contamination in it and it will eat away an oil tank liner that is not methanol resistant?  I just thought about this after reading your last post and I do not know if it is a problem.  Maybe an expert will know.

Wobbly !... I'm listening ! Have reconsidered the choice of sealer.

CK: thank you for your kind words.

Short update, as I'm busybusybusy. I can feel the dark clouds of time's-running-out decending on me.

The nifty little designer-starter I made ?...no good. Big mistake.
I have something up my sleeve in that department . More later.

The beautiful old SU carb: big mistake. Keeps giving me grief of all sorts and parts hard to come by.

Opted for a Keihin CV carb that is off a Harley.
HD used them extensively on several models, but folks tended to replace them with
big shiny bling-bling SS carbs and others, so there's plenty on the marked for very little money.
Got this one dirt cheap at the local HD repair/parts shop.
Looks brand new in- and outside



Great carb. It's a CV...good for blown application.
Easy to tune. Has a acceleration pump. Parts are readily available.

Just to be safe I got a rebuild kit and to tune it for my application
I installed a Dyno-Jet tune up kit. Comes with a variety of jets , a different vacuum piston spring and
other useful stuff.
LOADS of INDIAN riders use this carb and this modification, so all I had to do was
jet it "up" to 50/50 % gas/methanol



Fabbed a new intake manifold using my new-found alu welding semi-skills



...and fabbed a new carb-to-air-filter manifold.
Because I needed the space for the mounting bolts....



 ...I had to weld INside the tube,
which for this here still-wet-behind-his-ears "weldor" was quite challenging



...and had to cut a piece off a thin-walled pipe



...bore holes through the intake and attach the pipe-bit
to make provision for the air passing through the flange--into---carb---up to vent the area
over the vacuum piston.



NOT pretty, but it works
and taking into account that this is the 4th. real functional part I have ever fabbed in aluminum
I'm not too ashamed about it.



Later added a flange that attaches to the seat-"cowling", so keep thing from falling off.





This engine is looking ...erh....weird
