Got a basket case bike that I have as my winter project.
Was one almost complete bike and a couple of engines and a frame when I got it.
This is what I started with:
Tore it down and got the frame cleaned up, welded a few cracks and painted:
Rebuild began, all bearings etc replaced.
Öhlins shock rebuilt
Spokes etc replated
Wheels rebuilt
Some photos of the process:
Engine getting new bearings, and overhaul of the crank.
Transmission was good
Doing some porting to the cylinder after reading Eric Gorr's book
The bike as it sits now.
It will be a Broc Glover "replica"
Since it's near impossible to get any parts, exhaust etc to do a proper replica, I will build it to look like Glover's 86 bike.

The rear spokes are Z-spokes, and a first time dealing with that for me.
Front spokes are more like standard spokes
Sweet, nice to know that Eric's advice works that good.
The Shop
I had both the 250 and 125 brand new that year...I loved those bikes..
I loved mine, that was me on the 250 at the Mildura supercross in 1986
Awesome photo of you from the Mildura Supercross!
I ended up buying a white perforated tank decal from Evo-mx.
I can understand the hesitation to bring it out into the dirt, have the same dilemma with my build...:-)
Got the bottom finished, now waiting for the cylinder to get back from the machine shop. (Boring out to .50 oversize)
Some finishing touches and she is ready.
Have to weld up a new exhaust , install radiator hoses and some other stuff, but she is getting there
Pit Row
Been a fun project
Hope you enjoy:
Yeah, I did do a cleaning and used the best parts i had from two carburetors, but look like I have to rebuild once more.
(Not sure what happened to my post where I wrote about the flooding of the carb..?)
Anyhow, the bike fired up and ran absolutely great, and had a strong midrange as I hoped it would have after the Eric Gorr mod I did to the cylinder, with the Boyesen Reeds.
Will install a complete FMF exhaust, and I think that will help as well.
Thanks for the tip on the carb, will look into something like that if I can't get the one I have to work.
I bought a set of Super Stock pegs from Parts Europe P/N 277311 (Parts Unlimited)
They are wider than stock, and looks almost stock.
My favourite color on Yamaha's too!
Not too keen on the chrome looks of it, but it will have to do for now. Looking to get a "works" looking exhaust built for it.
Happy with the engine response. It has a really good bottom end with a serious mid range as well
Here is a short little video of the bike idling after the first start with the carb issues fixed.
