Insanely jealous of you. Especially for that 750...I've been searching and searching for a Duc twin and just haven't found one! Nice to see you got it running so fast!

Thanks,
well, I'm jealous of that 72 SL 350 you got, My first bike was a 71 and I've a 70 and 71 in the shop ready to start work on.
I'm trying to end up with a 71 out of the two. Maybe we'll meet up on the trail sometime I'd like to see that SL of yours.

Rocking,

You might run into that bike sooner than you think....but I'll not likely be the rider. I'm taking it to Raleigh on Tuesday after work to link up with the to-be-new owner's wife. They are from Deal's Gap, NC....right over there by the tail of the dragon.

The SL350 is an awesome bike but I need to pare down my projects and I really want to get my Ducati 450 Desmo professionally rebuilt!

Know anyone looking for a '74 Trident? lol

I'd give that 450 a try yourself. Their not to bad to rebuild, really.

So today, I put the valves in and put the head on. Then started setting up the rocker box and realized the pushrods just where not going to work unless I stretched them. Looked at the spares list and low and behold I was missing the push rod "Loose ends". Yep, they were on the loose. Looked through the bolt box 47 times and figured they'd must have fallen out on the trip east, probably somewhere around the Delta. But then I found one on the shelf where the engine bits had been and continued to rummage and found the other in a box of Ducati parts.

At least I hope I found the right push rod loose ends. I won't know for sure till some of the Velocette folks tell me on the Velocette group. I've never seen a Velocette push rod loose end before in my life. But they do fit the ends of the push rods.

I'll be honest, it's not so much that the 450 scares me, I just want to focus on the rest of the rebuild and not have to worry about the engine. Plus it'll come back all shiny and purty

Looks like you found the right extenders for those push rods...I've never ridden a Velocette before...are they supposed to be super torquey and quick? Sticking it into a featherbed frame sure leads me to believe it'll be a spirited little bike.

That 450 ought to be a great bike!

I know nothing about the ride of a Velocette. This will be my first one.
I have a letter from '84'. The fellow who built a racer out of it and ran it in the 60's to early 80's. Then cousin Mart got it, and started some mods, I'm hoping to finish it up what he started and hopefully ride it one day.

Right now the Ducati is continuing to give me fits. I've just rebuilt the carbs but still having trouble getting it to idle correctly. Rain tomorrow so
perhaps I'll tinker on it some more. I'm looking forward to have only one carb to tackle on the Velo.

The carbs are all clean at least...

Decided to jump on the Ducati this week since we were rained out a couple of days. Finally. Here's the story...

Update on the GT saga.

I've tried the Mikunis, gave up when the floats hung in them. That's my best guess. I didn't look. I decided to get the complete kits for the Dellortos.

So, had the Dells ultrasonic cleaned again...I ultrasounded them about 4 times each in my little cleaner. Then took them to a big one. Put the kits in. Couldn't get it to fire up. Flooding out. When I first got the bike I realized the vertical cylinder plug was about to strip out. And after 97 plug changes it did. So nothing to do but pull the head. Decided to check the rings since I had the head off and all looked good. Pulled the horizontal head while I was at it. Cleaned the carbon out of both.

Today I put it back together and then reinstalled the pipes etc...
In the meantime I'd put these small clear filters on. The bike was getting a small amount of gas to the front carb and virtually none to the rear.
I discovered this after a kicking marathon. Jerked the damn filters out and
she fired in short order. Then took to setting the carbs and syncing.
So, finally she seems to be running like she should. A nice PLAT PLAT sound coming from the exhaust instead of the putt putt. The vacuum gauges
reading equal at idle and 2500rpm. I think I'm on to something...

So were the air filters just completely restricting the flow? Did you heli-coil the head or just retap?

ah ha, they were small fuel filters restricting the flow of the gas.

Timeserts or the equivalent by the same folks that make helicoils.
It's a solid insert. I've never been a fan of the heli-coil treads fix.

Oh fuel filters...that makes much more sense...I dumb

I've never heard of time-serts before but I like the design a lot!

tinkered a bit this afternoon,

here's the engine case mount up with brackets for the Norton Featherbed frame.
Perhaps I should have called this a Velomanx.



Engine final assembly and snazzy engine stand (cherry plank cut off and Fiat bumper mounts bolted to rear tranny to frame mounts.

setting up the timing on the cams, I've found that the only scribed mark I could find on the crank gear was not at TDC, so I set the piston at TDC and made a mark (I hope I'm on the right track). There were several extra marks on the cam so I've got to set it to open and close per specs.

Set the cam timing, and then set the mag timing after the picture. I've set the running valve lash tonight and no hang ups when I turn the motor around.

Came in this evening and decided I had to see this thing in the frame.

Mart sure did some great designing to fit this up. Note clearance on rocker box cover for valve adjustment. I've heard others doing this had a problem getting the engine down low enough for that. Mart had no problem.





Crank side. I've got the front belt drive conversion hub sitting on the crank end.
Mart had fixed it up for a crank seal and o-rings in the hub so that oil can flow out to the engagement mechanism. I'll have to post pictures of that.
It's like a slip cam with a big spring which takes some of the pulse out of the
thump on the drive line I think. Might not be necessary with a belt drive but we'll keep it all if it works.
