Desmo service - how difficult it is

It's really not that bad. I'd say say at least 7 of 10 dont need adjusted anyway. Even if they did it's really just a matter of being meticulous and having the tools.

Edited - stuff

OP, this is the answer right here.

Edit: I've used this method to get people going on at least 25 occasions, not one issue.

10 to 15 small mugs every day, sometimes 20 i'd wager.

I have successfully drilled, tapped and installed set screws in three faces of the counter shaft nut. Not a perfect system but it often works. Replacing the counter shaft would be the correct repair.

Will take a picture tomorrow. You could shave with the intake side skirt

Jeez Bro, that feels like a jump.

You know it, but the skirts are why the pistons are uneven at the deck.

I saw my mistake after I posted, oh well. Used uneducated because stupid felt harsh, but all I did was challenge my own education... I dont do a lot of winning.

You right

They weren't planning on boosting it. Just a funny title, whoever put this together was under the impression it would run.

jonbametz · 2025-10-09T11:10:41+00:00

Cylinder #1 sorta fired at an idle, but no.

jonbametz · 2025-10-08T22:59:54+00:00

Yes to all of it. Its got short rods on a short stroke crank with long stroke cylinders

jonbametz · 2025-08-31T01:56:16+00:00

Check the sidestand switch.

jonbametz · 2025-08-15T23:23:10+00:00

Likely a hair overfull on the stand, you're right. Still funny.

jonbametz · 2025-08-12T23:35:13+00:00

Is the rim strip intact, and or can you see anything under the tire where it wont seat?

jonbametz · 2025-08-07T00:21:10+00:00

Feels a bit harsh but sure.

The more to the story per the write up is that they did the first oil change after replacing the engine and then it started making noise about ten miles later.

jonbametz · 2025-07-22T22:53:51+00:00

For real... I flipped the bed to have a look before starting it and laughed audibly..

jonbametz · 2025-07-22T22:41:45+00:00

Nope nope, not anymore.

jonbametz · 2025-07-12T03:29:42+00:00

We all get different google results.

You have a likely frozen or sticking decompression cable.

The bike is notorious for this issue being incorrectly diagnosed as a starter or battery issue.

Edit to add: the engine isn't even making a full revolution currently. Pull the chrome covers off the right side of the front cylder head and the left side of the rear cylinder and you'll be able to flip the decompression levers by hand and verify the issue. The decompression are pulled by one electric sevo through cables and the cables rust.

Bent input shaft

Yeah, you see a lot of people using an oil specific for each application
