Motor sitting for 3 years

[Morgs Motors]

Hi all!
This is my first post after years of reading.
Firstly, thank you for all the people on here that have made this site an absolutely invaluable source of information, and inspiration. Sincerely, thank you all.

I do however have a question that can't find an answer to in the archives!

I have a motor that I stripped and rebuilt 3 years ago. At that time, the fram wasn't ready for the motor, and with moving countries (again), new job, etc, the build timeline got side tracked.

Do you guys think it would be okay to flush the case out to get rid of any dust etc and get on the starting it up? Any other ideas? Any concerns?

Many thanks in advance!

Put some oil down the cylinders, and put some on the cam and rockers. Fresh oil and then turn it over until it has oil pressure with the plugs out. Then get it running.

Thanks Ratranger! I'm feeling more confident about it. New VM43's are en route so shouldn't be long now.

Hello Morgs and welcome form Virginia. Do let us know how it turns out; and pictures too.

I like two stroke oil in the cylinders because it's meant to burn. Probably anything would work though.

Hi Boog!
Thank you. Will do! I have to mentally prepare myself for working outside in the heat here. Just waiting on delivery of the new barbs before I get stuck in!

Stay tuned

Do it in the shade and stay hydrated.

Ratranger,
How much do you suggest pouring down each cylinder, and on the rockers?
TIA

Just enough to coat the cylinder walls, like a spoonful at most.

Morgs Motors, in your original posting you mentioned dust. Were you concerned because dust/fine sand had gotten into the engine, or were you just concerned about starting a motor that had sat for a while?

2-Stoke Oil: As bikefreakjon pointed out. I have used both 2-stroke and motor oil. Motor oil took at least 20 miles of riding to burn off whereas 2-Stroke is burnt off after about 1 mile. Motor oil smokes a lot and the 2-stroke only smoked a little at startup.

Hi Paul!
I was worries about both actually....
I've noticed a little surface rust on the top side of the valves. Not bad. But wondering if it will 'burn off'?
Also to dust etc..... I've blown out all the orifices with a bit of compressed air but will that be enough?

Thanks in advance!

Thanks bikefreakjon!
Appreciate it!

a little rust isn't going to hurt anything once it is running coated with oil it will stop rusting and usually they're pretty disgusting with carbon buildup so some surface rust is no big deal.

Blow it out, vacuum it out and fire it up!

Thank everyone. I'm just a few weeks away from having all my parts arrive here in Oman from the US. Fingers crossed for an August rumble!
I'll post a link to the video!
