1950? 500cc BSA project

[wayne z]

They ARE BIG, very BIG!!!! I think it will help a long way with getting "the look".

They arent chromed, they are alloy, so all ill need to do is sand and paint. But this bike is going to take a long time to build so i wont be painting them just yet, and i havent decided whether i want an old barn find look or nice and shiny.

Now i have my wheels and when i get my tyres i can start to get my frame happening, i havent been able to find another gearbox yet so i may just end up using the one i have even though it may not be the best. So i have the parts needed for frame dimensions. I just need to find a rear hub and have it laced into one of the wheels, then i need to decide whether i want to use the original front drum brake or find a brakeless front hub which in my opinion would look a lot better.

I would go with the front brakes. They look REAL good when they stop fast enough to avoid an accident.

I had a toddler run across my path once,he was chasing after some older kids that just crossed the road, when I was tooling along about 45 on a Yamaha 650. Next thing I knew was The bike was stalled dead stop in 5th, and I missed tht kid by 1 foot, and he never even saw me, all because of a pretty good front brake..
I guess though, if you have very wide open spaces, you could use caution and get away with less brakes.

If I were intending road use I'd definitely go with a front brake, but this bike will just be for my man room, shows and depending on its performance maybe a little flat track.

I think it will look a hundred times better without a front brake but not sure yet whether I wanna pay the extra for a hub and re spoking the wheel.

CONGRATULATIONS!!!!!!!!!
Are you going to build her a bike too? Dah!! probably, worlds first! pink Boardie
I'm going to start one for my grand daughter soon, she gets so excited and giggly just sitting on mine (she's 3) and tells every body "Babe gots bikes!"
Have fun with her, you got your work cut out for you and post a pic of the future Board Tracker

 

[harry76]

Thanks Truckd, i hope she likes bikes as much as i do. Ill definitely want to build her a bike when shes ready.

 

[Ibedayank]

Congrats Harry


It belongs to the Boss We do have a sidecar frame that will fit it so stay tuned....
Your going to want to make sure your decompression lever is hooked up to start that beast.....

 

[fasteddy]

Wonderful Harry. All the best to you, your girl friend and your daughter.
If you find yourself getting up in the night just to look at her sleeping that's normal. At least it was for me.

Steve.

Congratulations Harry!

Little girls are a lot of fun! Very special little people.

...You will still be able to continue on your projects... just not quite as much as you have been able to. There will be a balance in things.

Hope Mom is doing well.
Best

Wow,

Congratulations Dad!

If you lived close by I’d buy you a beer!

I wonder if a Kiddy's safety seat would fit in a side car?

Hi.... Harry..Any updates.....or it the new arrival keeping you busy.........

 

[DareDevil]

Hi Harry.....Looking forward to you getting back to this build.......DD

 

[harry76]

Me too DD, but im sick and tired of spending more time looking for my tools then i do on my projects. I dont have much space to work in so i am in the process of extending my garage for a little workshop..... Im accumulating a few more tools...... hopefully i can make progress soon.

 

[DareDevil]

Hi Harry...Just thought I let you in on this little beauty....its a methonal setup J.A.P 500..but its only a piston change and a petrol carby from being a bike motor....this is the motor I want for my next build....there not cheap but OOOH WEEEE!!!!!!..this is my type of ride..... its on ebay under motor cycle engines item #230847829472 ....DD

 

[harry76]

Yeah i saw that beauty, out of my price range though, but it would make for a beautiful ride

 

[DareDevil]

Hi Harry...Pity you missed the twin port Villers ... that was a good looking motor and would have good performance...DD

 

[rustycase]

john a. prestwich sure did make great looking engines! always liked the look of them...

probably would not need to buy new piston for the nitro-burner... run a stroker plate under the cylinder base to lower compression, re-jet carby much leaner for gasoline, then adjust ignition timing suitably...

fun stuff!

A point to remember is that the speedway engines were total loss lubrication. You therefore have to consider how much oil tank space you need, and where all the used oil is going.

 

[DareDevil]

Hi Ludwig 11....I use to race them in midgets on the speed way..a long time ago .. 1950's...building a replica BTR would be right up the ally of a total loss lubrication..not the mention the lovely oil pool under the bike when parked...
Hi Rustycase....I was always impressed by them to.........DD
