Yamaha prebug frame up resto/mod

[yambw’s]

This has been a long time coming for me both in finding the bike as they are super rare in the U.K. and getting the build of the ground 

[yambw’s]

Wheels and fram have been powder coated Managed to get the exhaust cleaned up to a ok standard it was pretty bad

[yambw’s]

Started to get the cases cleaned up and also managed to find a new set front forks that fit the drum brake I have a new set of panels waiting to go in at a later date

[yambw’s]

Clocks offered up

Few engine goodies! Only a mild engine build to start with

Nice build.
The Polini sport is a great kit for these engines. I really liked mine.
Those forks look good. Are they welded to the tree?
Ever time I took the BWS wheels off. I couldn't believe how heavy they were.

Thank you aeroxbud

Yeah I was really lucky to come across the forks! The old ones were just to far gone and I think these are better they seem stiffer and a bit more beefy.. what do you mean by tree?

Glad to hear about the Polini engine as it was cheap And the ports were super sharp when it arrived so needed some attention

Got this too to complement the front shocks

[Zino]

nice work
i have used that shock it was a good upgrade.
The polini is a great upgrade you are going to have a easy time popping a wheelie

I have heard that being a very light bike they are rear wheel happy

[yambw’s]

Started doing a few cosmetic bits and bobs.. going to do a satin black I think along with the rear grab luggage handle ,colour close to factory as possible

[yambw’s]

Excuse the pics round the wrong way after and before there

[yambw’s]

Got rid of the old style block light (on the tank) and got that slightly newer style, I think they were released with this light a few years after the first generation bws

I was referring to how you mounted the forks to the steering stem.I
My old BWS now has aerox forks. The early ones fit straight on.


I did find I had to space the cylinder up a bit on my vertical engine with the Polini kit. The piston was sitting above the transfer ports.

I do have a set of Aerox forks and wheels but I really wanted to keep the originality with the drum brakes and steel wheels etc...I do like the look of the Aerox forks tho...

So did you just double up on the base gasketS? what did you do about the squish ? The shop that sold me the kit said it’s ready to run out the box regarding squish ect ect it’s not a problem if not tho how did you get round it?
