Project: GB400 Cafe Racer re-rebuild

**durp** · 7th February 2012, 11:34

So after i got my hands on this, i had been building it up a little bit and was pretty content with how it was looking. But then the motor blew on saturday after the vintage bike races in pukekohe (only watching, wasn't racing). So I'm starting a full rebuild project.

Trying to get my hands on an XR600 motor, so if you know anybody...

Heres how it was looking as of saturday:

So sunday i decided to get started stripping it apart. Gotten it pretty much down to nothing now. Pulled motor, removed just about everything.

Began grinding off mounts that wont be needed now from the frame and smoothing them out.

Bugger about your motor

Try contacting Eelracing on here,I brought a GB500 motor of him about a year ago and he had a XR650 motor sitting there..... wether or not he still has it,is anyone guess but worth a try,

How much damage too the GB motor and if your planning on wreaking it I am looking for some parts well the cam chain adjuster

Smoothed off some brackets from the frame that wont be needed any more.

Ready to send off for sandblast and powder coating.

Would it not be better to wait to see whick motor your going to use before painting the frame?

**durp** · 8th February 2012, 11:27

nah

Just getting it black again. Just needs refreshed.

Im not going to go with a motor that wont bolt right in.

So what blew on the motor? You cant just fix it? they are simple motors.

Look for a NX650 domnator motor they bolt in and the gear box is round the right way the XR motor will have the gears upside down

also if you are doing the XR motor avoid the twin carb models (85-87) I think hard to get running really well

Thanks for that. Keeping my eyes open.

I haven't had a chance to crack the motor open yet. But from the sounds of it, thrown a rod or something. The cams turning but nothing happens.
