Got the timing chest and oil sump casting painted.

And now stripping the engine case. The inside looks brand new. But the outside looks like elephant skin.

Here is the "horror" of stripping the crinkle paint. It's like some gruesome crime drama - with plastic sheeting and duct tape... But the way, the duct tape held up against the paint stripper. I used it as a barrier to be sure I didn't get crud in sensitive places.

how do i upload pictures

And here's the "after" picture. Hoping to get this bike running in time for Arizona not-a-rally.

Looks good.

Keep it up Scud! It's looking great

Scud · « **Reply #274 on:** April 02, 2017, 06:19:41 PM »

A little more progress...

Got the engine in:

And repainted the heads and cylinders:

Oh my, that is going together nicely! Can't wait for the formal portrait...

Coming along very nicely!!!!!

Makin' some more progress...

Looking great! I hope one day you get a chance to share these pics with the folks at the Guzzi factory! You'd be an "honorary" employee of Guzzi for all of this amazing work!!

Roper plate is in... oil is in... and I'm away on business for a week starting today. Hoping to get her running before the end of this month.

There will be some cheering from Germany!

Well, she's taken her first breath after several years and the oil light went out almost instantly, but she's got a nasty knock.

As a reminder, this is the engine from a crashed bike that I got a while back (not Joe's original engine). I started it briefly before I dismantled the wreck and don't recall this knock.

Here's a video - does anybody recognize this sound? I asked over on V11LeMans too.

Check your valve lash? check push rods for straightness, rotate them between finger and thumb while watching them? DonG

Scud · « **Reply #284 on:** May 18, 2017, 10:24:21 AM »

I had the valves at .008" In and .010" Ex. I took it all off again and reset to a bit tighter - .006" and .008"

Here's a video starting on the left, which seems quieter, and moving to the right, which seems noisier.

I don't know how much oil is supposed to flow here, but it's hard to see since the oil is still golden-clear. Still, it's less oil flow than I expected (but I have no experience to compare against). It's about the same on both sides though. There was an equal amount of oil on the floor on both sides and my phone got splattered just from taking this short video.

Anyway... the metallic noise keeps pace with the RPMs so I do think it's something mechanical.

I'll probably pull the rockers off the RH side tonight for another inspection. Any other ideas appreciated.

Don G · « **Reply #285 on:** May 19, 2017, 02:32:37 PM »

Sounds like the clatter is crank speed? Wrist pin bush loose? Rotor on the crank loose? DonG

Huzo · « **Reply #286 on:** May 19, 2017, 05:46:45 PM »

I thought it sounded too long in between clicks to be crank speed, 1000 rpm @ idle is 16 clicks per second and that's what you'd hear if it was at crank speed. Also it sounded off beat in it's rhythm so I'm thinking it's tapped related. Not deep enough for a crank issue. Are you sure there's not exhaust gas escaping somewhere?

Scud · « **Reply #287 on:** May 19, 2017, 09:50:52 PM »

I don't think it's an exhaust leak, I installed new exhaust gaskets. I can feel the vibration with the sound when I hold my palm over the valve cover.

I took it apart again and found this wear on the rocker. Chuck suggested (on the V11 site) that I replace or resurface that rocker arm. Yet the question remains why it was worn that way.

Huzo · « **Reply #288 on:** May 20, 2017, 01:27:26 AM »

Notwithstanding that issue. That bike is too good for words, no bullshit you are another Old Jock. It is just gorgeous and I can only hope my Mk 2 comes out half as good. You blokes are a breed, a bit like guys who build their own aircraft. Just special, good luck on your quest to cure the rattle.

Tom · « **Reply #289 on:** May 20, 2017, 02:35:49 PM »

Definitely top end noise? and high pitch?

Scud · « **Reply #290 on:** May 20, 2017, 04:24:14 PM »

Thanks guys. I'm not saying anything is "definite" or ruling anything out - that kind of thinking has got me in trouble before. I might open it up one more time this weekend.

I actually rode it down the block and back. First time it's moved under its own power for a few years. It was good to feel the transmission shifting correctly after the mess I found in it.

Here's an evening *spy-shot* of the not-quite-done bike after her big *adventure* down the block.

Thanks again guys... yeah she's turning into a "looker." But I'm having a little trouble also turning her into a "runner." I've tried all sorts of adjustments and have not been able to get rid of the noise. I'm gonna focus on some other stuff for a little while and I may have to pull the camshaft to see what's going on and if I can find the source of the noise. Further bulletins as events warrant...

Don G · « **Reply #294 on:** May 25, 2017, 12:43:45 PM »

Here is an idea, pull the plug wire off on the noisy side when running, see if the note changes, will eliminate the guessing a bit. DonG

Top notch build Scud! Hope you'll figure out where the noise is coming from

Scud · « **Reply #296 on:** June 07, 2017, 12:01:23 AM »

Thanks Rick. Sadly, I'm "on hold" with this project for a little while. Getting caught up on deferred maintenance with other vehicles and house - and pretty busy with work - and riding other bikes.

Chuck in Indiana · « **Reply #297 on:** June 26, 2017, 01:19:20 PM »

Just a note of caution. I've read that pulling a plug lead off of a running computer motor is not a good idea..

Mayor_of_BBQ · « **Reply #298 on:** December 27, 2019, 07:54:56 AM »

Yo Scud, any action on this beauty?

Scud · « **Reply #299 on:** December 30, 2019, 09:26:58 PM »

I kept the thread going in more detail over at V11LeMans.com. The unfortunate ending is that I decided I was throwing good money after bad. So I stripped it and sold off a bunch of parts. I'm holding the Candy-Red bits for a potential future project.
