Looks like you have quite a bit to do there, I had a 77 Bonnie and had to do a main bearing replacement, found the bike to be fairly simple to work on with just the Haynes manual to go by.
There are plenty of parts around so that should not be an issue. I had to do a bit with the wiring as the tiny connectors that are standard had all corroded so a new wiring loom would be a good idea, both the master cylinders and lines on mine were shot too, so replaced them with new parts (easier and probably cheaper than rebuilding). I sold mine as I just couldn't come to terms with the riding position and my Trident was more fun to ride.

The brake resevoirs and cylinders were plugged tried to clean up but ordering new, got new wiring harness and most rubber (grommets,etc) my friend Chris had ordered many new parts back in 98
I rebuilt Front forks, stripped and painted frame. Had to weld coil platform. had friend paint tank. Trying to rewire, don't have picks of underside of rear fender. Have just ordered Enthusiasts renovation book. Seat isn't original but I like it. had seep test done on engine suprisingly no leaks. Thanks for your intrest.new rear.jpgnew rear.jpgframe.jpgframe.jpg

So sorry to hear about your friend and his wife, never easy to lose a friend.

I know you'll do him proud, as you've already shown great progress.

I'm back. But more confused than ever. I'd asked about left right in manuals. You and Grandpaul both said as the rider would see it. The Trimuph workshop manual for Bonneville 750 says the wider spacers for mounting engine are on the right. but the parts manual picture shows wider spacers are on left. help please. Sitting on the bike are the wide spacers on the right? thanks

Fit up everything else snug but not tight. Set the bike up on the centerstand. Get down under there and have a look, the answer will be obvious.

Thanks, that's what I did. Just got worried that it didn't match manual, afraid chain and rear stroked wouldn't line up
So happy I found this site

I can't find oil feed lines. Is there an alternate line I can use like gas line? I've got the breather lines but can't find a supplier for the supply/feed lines. Thanks

All you need is petro-resistant hose. Most auto parts suppliers carry it in bulk.

MAKE SURE you don't cross-connect the connections at the engine!

A very valid warning TUP TUP This is easy to do and not realize it.
