After about 40 yrs she is finally roaring again  ;D
Used the battery out of the boat to start it. Initially she would not start, there was spark but the plugs were dry  >:(.
All the info I had said the floats should sit parallel to the bowl seat. When I rebuilt the carbies the floats looked wrong, so I adjusted them. Initially there were a few pops but she would not fire. So I adjusted the floats back to where they were, she immediately started - yoohoo!!! ;D.
There are a couple of issues. There is an oil leak where the oil cleaner housing meets the squash plate. The o-ring that was supplied with the filter appears too small for the groove in the oil cleaner housing. The squish plate to the engine is oil tight, as I machined that groove for the O ring! Might try to get a 4mm section O ring for the factory oil cleaner housing.
Also the starter solenoid has died after the demand of trying to start it with the wrong float height.
But she is going  ;D and the carbies appear to be working well without any obvious need to rejet  ;D  ;D  ;D
Video of her first start in 40 years

Good work!

(I think you need a couple of ockies to restrain your fuel tank.)

Would it be possibly that you post some pics how you dealt with the electrics on the bike (ignition box, relays etc.) thank you!

The best thing I have done is clean up the loom using proper automotive connectors with 6.3mm spade terminals. Photos of the main electrical items are attached. The fuse box is not really hidden as you do need access, and I did not want to have to remove the seat if I blew a fuse. Battery (now ordered) is under the starter solenoid.

Spent some time today fitting the Modern Motor Cycle Company lithium battery today - at this stage it appears to work very well. Starts the bike easily.
The bike starts very easily with either electric or physical leg.  ;D
Now for the bad.
  • There are oil leaks at the gear shift, and crank- not a big deal to fix
  • The F&@k#*g thing is not charging. My pet hate! >:(
Nanno - I love that sound also. That's why I have bought 2  ;D ;D ;D
