After my first engine rebuild ever, and the bike previously having sat for 12 years, I got it started tonight ! I haven't run it up road yet, but I'm happy as a pig in s. Many thanks to all who helped, it really made a difference. I'm sure I'll encounter problems once on the road, but for now I'm having a celebratory cup of tea and a scone.

That's good news. In the end, what was the problem?

I had originally kicked it over with no plugs to get oil moving through, and I could see piston going up and down. I also did compression test, all good, but one cylinder had no plug or tester. Once both plugs were back in, it seems the extra resistance ( compression) caused the clutch to slip very slightly. It felt as if engine was turning over, but it was only clutch drag plus a litlle engine rotation. It really fooled me until clutch bit, and then kicking felt and sounded completely different. The clutch seemed better tonight, so instead of checking carbs, I gave it a few hard kicks and it started up. An odd one I must admit, but it's a lesson learned.

The motor not turning over because the clutch was slipping explains why the spark plugs were dry when you first tried to start it.

And this DOES fall under the "Compression, Ignition, Fuel" order of troubleshooting! Even though compression had been checked earlier, NOW the clutch was slipping and a compression tester would have read 0 when kicking over. Although, come to think of it, a compression gauge would not have shown the problem unless you left the opposite plug IN, which you would not normally do. So good on yer for figuring out it was a slipping clutch.

One case where a compression gauge might do the job and a Leakdown tester would NOT! A Leakdown test would have shown that everything was OK in the cylinder sealing department ... the compression gauge would have shown the failure to turn over (plug in one cylinder and gauge in the other).

But it's like a golf scorecard - all you have to write down is your score for the hole, NOT draw a picture showing that the ball bounced off a tree, a rock, and onto the green. It's running and that's what counts .....

I stopped believing for a little while this morning. Journey is really going to be upset.

Nice !!! Years ago @ Daytona at the track watched a guy kick his ballsoff on a Wetback Tri-Twin, mow-si'd over, new brit bike guy, His crew chief buddy dumped a can of STP in with his oil change for bikeweek. He was fuk'd!! talk about non running clutch slip would'nt even push start!
I know you know to grab the clutch lever & kick through when cold start to free the plates. I don't even mess with that I just stick the trans in 1st and rock the bike back & forth to bust them loose. Got 2 Beeza's with a wet clutch An A-65 & B-44VS over the years Ford Type "F" or Primary oil for a HD. works good, minimum sticking. Barnett fibers in both helps also. Glad it got going!!! Need them Bezza's out there zoom'n about good job.
