Detour
Published on 2012-04-15 04:08:00
Lined up part of the next project - spotted a cheap Yamaha RD250 engine for sale online and bought it for €55.00. Its a 1975 twin model and needs a lot of work as you can see from the pics below. It came with the original 28mm Mikuni carbs and 2 ignition coils which seem to have been butchered at some point.I am thinking along two different directions for this project, [1] transplant the engine into a Yamaha FZR250/400 chassis and [2] cafe racer.

This evening I fitted the expansion chamber after spraying it black yesterday with heat resistant paint. A few weeks ago I did a bit of a de-coke on it along with the end-can. I heated it up to apply the paint and it was still smoking but nothing to the way it was before the de-coke.

In an effort to complete the assembly of the right hand hanger I made a master cylinder plunger/piston from a plain bolt. I cut the head off and used a dremel to round the top. I applied red rubber grease to the contact point on the master cylinder. This is a stop gap until I happen across the original plunger.

Usually 1 but sometimes 2

was planning on getting a lot done today, rear wheel fitted with brake system and realised the wheel bearings I got are the the wrong size. But I cannot tap the originals out so I started with removing the rear wheel sprocket carrier and of course the bolts were seized and not 1 but 2 broke off. With them removed I cannot remove this part of the wheel ?

After fitting the left hand hanger and gear change mechanism I moved on to the right hand hanger to start assembling and realised I misplaced the master cylinder plunger. I remember cleaning it and painting it and I vaguely remember putting it "somewhere safe" so that i'll "find it when I need it". Spent about 45 minutes searching for it.I also need to find a home for two alternator earth cables, in the workshop manual it says to bolt them to the engine and shows a small image of the location bu [..]

Adding on
Published on 2012-03-28 17:19:00
Got a good bit done over the last few days adding on the bits and bobs. Got the handle bars, switch gear and lever housings on. Got the rad and battery box subframe in and at the back end the rear light and splash guards along with the oil tank. I then attached the electronics and rear part of the wiring loom. Its coming together a bit more but looking messy too!

. . . meaning there's 1 wheel! Forks and front wheel fitted. All stainless steel bolts fitted and new bearings in the front wheel. I refitted the original brake disc as its within the service limit. The rear subframe has 3 coats of black paint on too to try and keep the rust at bay. The wheels have also been painted the original black by an auto body repair shop.Here is a link to the before post >

Spent a while this evening cleaning and tidying the working space to start the bike rebuild. I got the engine mounted into the frame, swingarm and rear suspension - all the mounting bolts have yet to be tightened and the originals have been replaced with stainless steel where possible.
