I bought an '84 Aspencade mostly disassembled that has been sitting up for a few years. I am in the process of trying to put the bike back together, but have run into a snag. I tried to get the engine to turn over, but it seems to be locked up. Any Ideas ???:confused:

could be a little rust around the rings pour a little desiel into spark plug holes and let set for a few days then try to turn over it somtimes works

Thanks Radar, Someone else told me that too, so there must be something to it.

You can pour a little Seafoam in each cyn and let it set for awhile also. Wonderful stuff that Seafoam.

Never heard of it. What is it and where do ya get it ???

It's been around for a long time. I buy mine at Walmart. It saved the carbs on my Yamaha. It can be used as a fuel additive and crankcase cleaner. It comes in a red and white can. Read the can for instructions.

I'll have to give it a try, thanks for the info.

Oldsters.....(wait a minute, I AM one now) swear by Marvel Mystery oil for unsticking rings and curing oil burning. Let it soak for a long time. I did it once on a 750 and I hoisted the fork so cylinders were vertical, so MMO penetrated. Oil burning was then intermittent, not constant. Tough to do on a GW. I had not heard of Sea Foam until I saw it recommended on this forum, and I did find it.
I am also screwing with an old GW that was left sitting, see my new post. Good luck with yours.

Sounds like good advice given, I was going to say use "Moovit" to free up the engine which is what the mechanics use but seafoam and diesel works just as well too.
I've also squirted WD-40 into the spark plug holes if the heads were on.The trick is to let it sit for a day or two to work its magic.Heat helps too but carefully,the metal expands loosening the rings because they get a set to them against the cylinder walls from sitting so long.

I myself use PB BLASTER, Its has a great wicking ability. I am about to go down in my garage and add a little bit of motor oil to the Pb that's been soaking for 2 days then later tonight I'll turn the motor over.
I've been a motorcycle mechanic since 1969, A little heat is also beneficial. I will never force it hard just give it enough time for every thing to do its job how ever long it takes. A tip I got from my gunsmith/farmer decades ago for stuck rings when the motor smokes is to let it soak with Hoppes #9 gun barrel cleaner to dissolve carbon in the rings and piston lands after a motor has sat for a while. I've had success in the past doing this.
Patients is a verchue. That some of my 2 cents but I'm sure it's not the only way. Head

All Good Advice Guys, I did add the WD-40 to the cylinders through the spark plug holes, and I am letting it sit for a week or two, then add more.
Thanks for all of the advice.

Let us know how it goes .:)
