1955 A7SS racer ...possibly

[Rocket Racer]

If all goes to plan I hope to have the frame back repaired, source the petrol tank, a CR box and a suitable barrel this sunday. may then be able to start offering bits together into a preliminary mock up.

Hi RR,
I posted some pictures of the TD fork bushes , I think in my post about the dampers?
An issue with fitting the TD top yoke is that it moves the stanchions down so where the bottom yoke clamps can have moved to the non parallel part of the leg
Some time ago Autocycle Eng. Had stanchions that are parallel all the way at the top end, which also helps with fixing clip on bars

John,
yes thats been on my mind and something I havent sourced yet. the sliders I have are mid sixties A65 half sided type so should have damper rods which I dont have. So do need to start progressing pulling together the missing front end bits. I'll investigate autocycle eng.
appreciate that. While I have what resembles a complete front end, in practice the stanchions, bushes and damping are all still required.
Thanks
Tim

I've emailed them

Interestingly had a contact back from the stanchion supplier John put me onto, they typically recommend shortening the stanchions so they stay the same height.

However more news and it had me recounting monty python; "ye seek the graile" as I have now sourced the biggest missing part I wanted as well as some petrol tanks and some new CR gears for a box.

I have in my possession now a slightly battered (needs a fin and resleeving) genuine small  fin Daytona barrel  , it makes my thick flange a10 barrel look quite flimsy.
Just shows what BSA were up to in the states to do what they did! Will include pictures showing side by side with stock A7 barrel

Yes BSA made small fin super thick flange a7 barrels! (5/8")

G'day RR.
You found the pot of gold there mate.
Wish I had those barrels on my racer, and tank too.
Cheers

Nice one RR, those A7 barrels look to be well bored out though, mine were @ 80 thou over.

Mine would count as 80 thou over... on an a10 
Looks like it got taken out as far as possible, also has several helicoils so hardly mint. Does need TLC.
Certainly some way off looking as pristine as yours and too big to take an a7 std cylinder sleeve. I hadnt realised how common they are, every other forum members got one 
But I think I can do something with it. The answers usually money .

The brand new 1st and 2nd gears I've got will convert a STD box to the ratio's 1.932, 1.46,1.1 & 1 which gives me a 50+ mph first once I actually fix all my knackered bits (on the bike) and build it

This is the one you want, A10 version as used by Gene Theisen

Hi RR,
I just saw these TD  long fork bushes on ebay (nothing to do with me)

Thanks John, I'm going to get some hard chromed gold star type stanchions and shorten the tops and recut the threads given the stanchions will be visible having clip ons fitted.

I seem to have a sufficient decent pile of largely shagged parts now to claim there might be a motorcycle, so will start cleaning them up and getting them repaired.

[Rocket Racer]

frames still being retubed, waiting on some parts to consider, forks are also with engineer. Hoping to have enough bits to at least start mocking up and get excited about. I think realistically this bikes going to take a little while to figure out my options. 

I did recently source a good 2nd hand a65 cam and some followers to add to the options list
the combination timing side bearings turned up.

[Rocket Racer]

rearset footrests... are these std or homemade?

G'day RR.
At first glance they look like plunger type but the mounting hole looks much smaller. Have the holes been sleeved?
Cheers
