CB250Rs Rebuild

<< < (3/7) > >>

MCTID:
Same with my 1970 Triumph. I had that bike since 2007 and had stripped all the paint off it by hand and repainted it using spray can primer and finish coat. Had it for years and one day I stuck the swing arm back on and the rear wheel only to find that the wheel was about an inch out (25mm for the youngsters on here). Never thought about the frame being bent....never entered my head. I had it put on a jig and straightened - £150 as it was so bad !

Good advice on here from Laverda Dave.

MRA464:
Thanks for the reply guys, frame alignment was not something I had thought about.
Once the frame is sand blasted I will carry out an inspection for welds and then get the frame checked.
I might even get it to work and build myself an alignment frame to check it against.

The strip down continues.
More rust and debris, but not too many major issues. Front headlight rusty bezel and outside of reflector.

Full Harness removed along with clocks and all the bracketry. Not sure if this is correct but one wire not connected, may be someone could advice.

Forks show pitting and chrome damage, we will look at the damage once cleaned.

As I said before the general idea was to get everything off the bike ready for a top end engine inspection. Parts are set aside ready for inspection and reworks at a later stage.
The only major issue was whilst removing the Carb the inlet boot fell apart -oopps. Apparently these are impossible to get so I will be looking at a repair of some kind.

The bike had a seized front brake, so after removing the caliper and  brake line it was obvious that the master cylinder was at fault. It looks like it has a seized piston, so another job for the list.

After several hours work and a pile of parts, I got it down to just the frame and engine.
So this will be the next post, as this did not go as planned, my first real issue.
More to follow

Bryanj:
The extra wire is an earth for 3 terminal flasher can, as for intake perhaps modify something like 400 four

Bryanj:
There have been a couple of the inlet manifolds new on ebay but sold expensive put the part number, 16211471000, into a search and save it

Laverda Dave:
The extra wire is correct, the flasher unit on the RSA only has two terminals. You can get the headlight from DSS and a few others, they were used on a few models.
I gave up trying to repair the master cylinder on mine despite buying a repair kit. I found it impossible to separate the fluid reservoir from the main body to allow access to the piston assembly. I bought a new pattern part in the end and it was actually cheaper than the repair kit!
You can get a stainless brake piston, seals, boots and bleed nipple from Powerhouse, they will overhaul your existing caliper and repaint it if you want them to.
Renew the balance chain whilst the engine is apart, it works hard and is prone to stretching. Don't buy a genuine replacement at £250+, a DID gold heavy duty go-kart drive chain is better quality once you cut a few links out.
