Hi guys

Can anyone identify what year this frame is from?

Frame number :  1a1 310169

Hi guys
So, considering picking up a box of parts, Its a yamaha r5 frame with rd400 front end, swingarm and engine.
Engine is not in the frame

Its a project He is selling

So my question are
Can i fit the rd400 engine in that frame? Pipes as well?
What about fitting a later Rd350 aircooled seat to the frame?

Any info would be Very kind
Thank you :)

Hi guys

So iam looking at diagram the Best i can but Cant seem to see where i have done wrong.

Can anyone tell me Which colour wiring the 2 wires from the rear brake sensor, goes in to?
As well as tail light

Because i can get rear light to work and the front brake light but not the rear brake ( only made rear brake light work by trial and error and then the tail light did not work)

Would be Very nice to have this done as Its the only thing not working

Yes so my brand new horn.. Hardly says anything on a fully charges battery.

Why? 🤔

Yes so i was testning wiring in the back on the rear brake light.

Everything works Besides that and now All the sudden i Cant hear the relay switch when tuning the key over and No light. Its dead.

Battery is fully charges and it seems All fuses are intact.

What the??

Hi guys
So my ignition, where i put the key, is old and worn on the sticker so not sure what position does what.
And because iam figuring out my wiring harness, can anyone tell me what click with the key does turn what on?
I believe you can turn the key 3 times to the right.

Yes so, took it for a spin and the clutch was Very Hard to pull so had the clutch adjust cover off and went up Till 3 gear i think, it had a Hard time shifting.
Then the screw came off  the clutch adjuster and No more shifting. Ive fixed the adjuster but the damn bike wont get into neutral or Any other gear Its stuck in 1? I think

What can i do and Any suggestions to what happended?
Total restored bike

So, got these 2 set of cylinders measured. Fresh bore but can i get pistons to fit?

1 set measures 64,90 mm
1 set measures 66,10 mm

Anyone?
Or do I need to rebore and hone 🤷‍♂️

hi guys
is there any problem in doing so? its because i have a old stock rd250 frame, but mainly 400 engine parts. thinking about maybe making a 400 out of a 250 frame, is there any issues with that?
mount rd400 triple tree and 400 fork legs and basically make it a 400?

those are the only 2 differences or? engine capasity and fork legs

Hi guys
So, had a crank rebuild, it came with smooth bearings, mening they did not have the pin on Them that sits in the engine cases.

Is this a problem?
Tips, recommend?

Hi guys
So iam gonna attack the dreaded wiring. I have it up and running and basically only need wiring done.
So gonna remove tank and get started, but one question in particular

Ive tried to use the instruktion Chuck made in his thread Which is awsome, but the red wire that goes from the rectifier in this ignition kit, when i mount that on plus(positive) on battery it start
To almost spool up in the rectifier and if buzzes in the entire frame. 🤷‍♂️
Not sure what i have connected wrong here but Any tips, help is appreciated :)

Red wire on this picture is my make shift from the rectifier

Hi guys
So, this damn caliper ( front for now) is giving me a really Hard time.
Setup :

Brembo master with braided line for single disc
Refurb calipers wirh new ss pistons and fresh rubber.
I just Cant get it to garden up on the master. I can always squeese it in to the handlebar
Allthough the brakes are biting somewhat to the disc, Its crap.

What do I do from here?

I have already taken the caliper apart, Nothing seems to be of Any issue.
Also tried to check if the membran in the master is working, it squirts fluid up when i pump but it just never gets better.

Help

And yes ive tried with vacuum and bleeding from cylinder to master as well, no luck

Hi guys
So hopefully i can make sense of this

I got the silver rd up and running.
Its brand new rebuild engine and k/n filter y boot,  spec 2 pipes and main jet 210.

So just did a test wire hook up to get it running, and if i understood Chucks guide correctly, the red wire of the regulater/ rectifier goes to + positive on the battery?

Its just did that today and a humming from it just sounded constantly so removed it offcourse.
Also the Black wire going from the relay ( that comes with the vape kit) i just connectee with a Brown wire from the ignition ( one in a connecter on the wiring harness) not sure if this is right but turns on when i turn the key

Anyone? 🤷‍♂️

Hi guys
So first start of my rebuild bike. Complete rebuild engine

Also starting dripping at one point from the pipe? With fuel

Does the carb throttle slide? Sit a bit low?

Found a litium 12v 2 AH battery that fits nicely in my stock battery box
Is this to small power wise or would be allright?
