RD350 Cafe Racer / Brat Project

Hi Guys,

I am UK based and this is my first build, I managed to pick up a Yamaha RD350 from ebay that was badly advertised, it was just described as 'yamaha rd350' with one picture:

From the original picture it seemed it may need a lot of work but also looked like it could be a promising basis for a great two stroke cafe project, i decided to place a few bids and won the bike for £600, the next day my dad and i set off with a rental van to go and pick it up. We got there and to our surprise the bike was in very good condition for its age, it was obvious to us that it needed some work however it was in a much better state than we anticipated, and the reason for the sale was that the previous owner bought it thinking it was a 350lc.

We got it home and into the garage where it sat for a few weeks until we started to strip it down.

Incredibly everything went very smoothly (not to jinx the rest of the build or anything) but parts came off like butter. It was apparent that somewhere down the line someone had previously started this build and had either run out of money to fund the project or had encountered some serious engine problems.

A week later pretty much the whole bike was stripped down, we decided to crack open the engine and to our surprise it had been converted from a 350 to a 250, we are guessing this, as the gearbox is 6 speed but the top end is a 250. So the plan is to re-instate it back to its original 350cc engine.

Aesthetically i am wanting to go down the brat route, one because i think the style looks awesome, and two because this style is very rare on a rd350, is there a reason for this? For example rear tyre clearance?

So plans are as follows (I am open to all kinds of suggestions from you guys).

Convert engine back to 350cc
Electronic ignition
Remove oil tank and run on premix for slicker look
Expansion pipes (possibly DG, maybe handmade depending on money)
Rear sets (these are hard to find in the UK and I don't want to import due to costs, so suggestions would be great, i also wear a size UK11 shoe so i need plenty of room)
Cutting the rear frame and installing a rear loop (not sure on rear tyre clearance for this?)
Removing frame seat tabs and other tabs i will no longer need
Powder coat frame black
Powder coat wheels fully black
Brat style seat, brown leather
Get the forks re chromed
Clip on bars with brown leather grips
single tachometer (possibly just rev tachometer for a sleeker look)
New front headlight
Rear light (small round type)
New rear shocks (simple black style)
Need new air filters
Front brake calliper and braided hose
New tyres possibly bridgestone (wanting to go as wide as possible on these but retaining the best possible ride and performance.)
Tank repainted either cream white or matte blue

This thread will be updated with more images throughout the build.

Thanks for your interest and any help / advice you may give.

She's gunna be a mean machine once you've finished her, for hand made exhausts speak to Ben at Rayson's crackin lad and top notch job he's just done a twin set of open mega's for a Sealy Norton we are building (see pic), if your anywhere near manchester and need chrome, powder coat, zinc, bead blast, vapour or anything give us a call speak to me (dave) and ill sort you a good discount.

sounds good mate, can you re chrome forks? mine are badly pitted? Where do you work?
 
The reason you don't see any brat rd's is that an rd is essentially a street legal race bike.
Brat bikes are for cruising, rd's aren't.
But I say go with what you like, I'll watch.

Good looking bike already

Yeah that was my thought, i am concerned about the clearance though as there doesn't seem like there would be much room between the rear tyre and a loop if i was to weld one on. Aesthetically i want this bike to be stunning, i do want the performance to be good but its not my main priority. Its my first bike, so i'm not looking for a rocket ship. thanks for your reply!
 
before you weld a loop on you need to settle on what shocks and tires you are upgrading to
then remove the springs from the shocks and bottom the suspension and leave an inch of clearance to any loop/fender,this is not rocket science



i did not know that the mental retardation that is the hideous style of brat bikes had invaded britain

Thanks for the advice on shocks. However if you dont like the 'mental retardation' of brats each to their own, i personaly like the style, and fancy the challenge.
 
Welcome to DTT. I'm a fan of the RDs in all their glory. Looking forward to seeing what you come up with.

We are based in Ashton-Under-Lyne Manchester take a look at our website for more info www.noisychrome.tk We dont do forks (engineers chrome) in house we only do decrotive chrome (fork bottoms, mug guards, exhausts, tank ect) but we can send them off for you, we are a bit of a one stop shop for restorations :)
 
This is a very quick mockup, ignore the pipes, i didn't have time to photoshop anything in place, and also the wheels are spoked, i will be keeping the alloy ones currently on the bike:

im currently restomodding a 250.nice to have a fellow builder around.

BTW:
in which condition are the 250 cylinders and pistons?
is this a 1 a 2 model? im looking for these parts for my project.

you may get a contact or two for parts on the above forum, but stay on here as well, I love RD's and wanna see what comes of this one
 
another RD owner checking in.

you will find these bikes are plenty fast, especially to the standards of 70's tech limitations.
