Two more, you guys are quick, welcome aboard.  So...I'm thinking I should try and fire up the 750 parts bike just to see what I get before I tear into it.  I'll need to do a quick clean on the carbs and a bypass of the ignition switch but otherwise it looks like it's all there.  I'd like to know if the low mile 750 motor is good to go just in case..

That's a killer deal you got there and piles of spares.  41s a are just a touch on the large side for a 1000 and huge on a 750, so that means big bore kit is needed and hot cams and....     oops.  There I go again.  And I told my therapist I had that under control.  Ah well.

Stock carbs are 38mm CV (I think) which is about the same as a 34 slide carb.

From memory the Thunderace had the same frame as the 750 (they slightly modified it at the rear), so the engine swap is fairly easy.


If those tanks have fuel in them and they have been sitting then the fuel pumps are probably stuffed (they sit in the bottom of the tanks). You can easily adapt an external low pressure pump though.


Nice score - my brother in law still has his 750 after many years and he still loves it  8)

That's what I was thinking, big.  I don't know if anyone's been inside the 1000 motor but reasonably certain the 750 hasn't been modified.  Also why I should try and start the parts bike motor first.  The FCR's are a little crusty but will clean up really well.  No airbox or stacks for them either.

Thanks Hillsy.



Yes, both tanks I have are crap inside and missing the pump and lower covers.  I think the black tank (relatively undamaged) should clean up.  I was starting to read about the fuel pump options too.  I'll need to figure that out.
