Got in the garage yesterday.
as usual, nothing that you buy new actually fits together. even when 2 pieces are new.
Like the axle and the axle sleeve.. clearly they don't account for the chrome, so clearance is non existent. took me ages to sand down by hand the damn axle.

Ended up not having much time.
Tried out this narrow long front I have had for ages, mainly because I was curious to see how it would look. Love the skinny look.
Not going to use it though as I want to run a front brake and it's too narrow.
for now I'll just put a wide glide, left drum brake and go with that.
A front end is something easy to swap at a later date.

anyway... some photos.

I've always liked the look of a speedmaster on a 21" with a wide glide. Course then I like a 16" at the back too. For the 18" rear matches better with the narrow front.

thrown a bit more at her today in between wrapping presents..

Gearbox, oil, brake linkages and forward controls.
added a split clamp and cut a set of handlebars I had made ages ago just to make her look like a motorcycle... they seem a bit too high.
but then again, in my opinion 3 things compliment eachother and can change the whole look of a bike... it's the handlebars, tank, sissy bar combo. a change on those 3 make a hell of a difference.

anyway, enough rambling.. photos!






and ended up the day putting an old sissy bar I had made years ago, just to see where we are.
My plan is to build a new out of stainless, likely with a diamond top.

got back in the garage today after the festive season and should be back in there all day tomorrow....

Not much progress...
Dropped the engine in, but have massive gaps that need shimming. On the other frame this engine was there was only shims on the front right mount.
But when I dropped the engine on this one I felt it rocking in the middle of rear mount... thought was strange.
So tighten up the rear bolt on the belt side and have massive gaps.... rear and front.
Engine is matching cases, not sure if they ever been apart.
Dont think the rear was shimmed on the old frame.. but maybe it was, I just didnt noticed when I pulled engine out.
Also, frame quality is good, it's a VG frame.... Going to pull the engine out tomorrow and see if there's any dirt under the mount.

If there's a burr or something, should be alright to just flap disc it? then shim accordingly?

Sissy bar is temporary.
Will need other rear fender too.. this one doesn't match the 18" curve as well as I initially thought...








Also.... stupidly I forgot to take my tranny plate off the old frame when I sold it... and the only one I have is off a later box. Meaning now I have the box sitting on top of it as it won't fall into the middle slots... trying to get one fast so i can crack on with lining things up.. get the belt on, chain on.. check where rear wheel is going to end up so i can then make fender mounts and all that.

When you pull it you can straight edge the engine and frame and see what you got. Does look like something is under the mounts.

yeh I done that this morning.
It's a rear mount that is thiner on one side...



it's all nice and flat on the engine side though, I checked that.

So, the next thing was to see which side would be better to bolt and which side to shim
What I done was bolt down the rear belt side and measure gaps everywhere else - noticed that with this side bolted, then I'd have a sloping gap on the right side

It seems that after all my measurements, the best way to go is to bolt the kicker side down and shim the rest, it seems to have the less gaps and less inconsistency, plus the top motor mount also sits flush on the frame mount on top.
Took a photo of my results to send to a friend, in case you here are interested.



Then came the moral dilema of cutting the rear tank tabs off. Beautiful frame but to keep them would have meant a load of fabrication on the tank, to make a box inside, and to be honest is a lot quicker to weld tabs back on... if by any miracle they will ever be needed again.

I'm liking how she sits.
stuck with the gearbox though.. can't find anyone over here with a Pan transmission plate.... dammit

Looking good so far.

Question, are you having a conflict with the sift linkage connection to the transmission ratchet hitting the oil tank?

It looks like you have an FX ratchet top, they had the linkage attach to the top of the ratchet, the FLs and all older than early 70s had the linkage attach to the bottom of the ratchet. Not positive, but the shift drum may be reversed because of that, if simply flipped on the ratchet attachment the shift pattern would be reversed.

I'd check parallel axle angle to engine mount, and trans mount angles with a digital angle level. While your at it won't hurt to check neck is perpendicular, too. A little time spent with a file will get the mounts flat and parallel.

I would send it back, I would expect better of VG. You paid good money for that frame and you deserve better, after all it's not a VTwin frame. Even the best can make a mistake, let them correct it. It may save them grief down the road.

Yes, FX ratchet.
won't be any conflict, I had this setup working when this drive train was on the 70's frame.
But I'll be going jockey shift, which is the ideal ratchet for this as it will be 1st gear forward on the stick and all other bang,bang,bang to the back.

let me see if I get it what you are explaining..
digital angle gauge (got one) mounted on top of the rear axle. check angle
then gauge on the motor mounts and see if they match the same angle?

got that right?

I did think about sending it back, but as richbob says it would be a right pain, more time waiting, etc,etc.....
Not ideal, but I did weighed that option, plus the fact they might come back and say "it's within tolerance"... so I thought hard about it and then cut the rear fuel tank mounts off... now there's no going back on the frame.



I need to find a rear fender that works well with an 18"... the one I have although is perfect in design, the curvature doesn't match the 18 perfectly as I would like. any ideas on something that would fit an 18 nicely?

I saw that how to on lowbrow website about using 2x4 wood planks and open up the edges so the radius open... so I'll give that a go first this weekend, but I'll have a look at those guys too, i'm not far form Bournemouth
