New to me '75 GL1000

Post by JimJones117 » Tue Feb 19, 2019 10:11 am



Hello! As it says in the title I picked up a 75 GL1000 yesterday. Farm fresh in Candy Red. 20k on the clock. Going to be a long term project as she has been sitting for 4-5 years in a dirt floor barn, and I am not the most mechanical person. Attached a few pics so you can see what kind of shape she is in.

Any suggestions appreciated.

Jim

Very first thing...Pull all 4 spark plugs and HAND crank the engine..Don't even attempt to start it yet...
I always suggest to see if the engine is runable before doing anything else.

Thanks!

Would you MMO it before trying to turn it over?

MMO? Marvel Mystery Oil? Where would I pour it?

Thanks!

Remove timing belt covers and you can probably turn it over by hand, but it is risky to try and start it without new belts. $25-$30 from Napa or wherever.

Take out the spark plugs (make sure you have a good bite on them - you don't want to strip those out!), And pour about a teaspoon through each sparkplug hole.

You will have to change the timing belts, and you can rotate the engine from the front or back.

Pick up or download a factory service manual, you're gonna need one.

Thank you for the information. I have ordered timing belt so it should be here soon, I also ordered a Clymer manual and a 75-79 Honda GL1000 Service manual. Going to try to rotate the engine this weekend!

Rotate it from the stator bolt NOT from either timing belt pulley.

what happened?..........i hope you are a patient person! these are marvelous old bikes, but looks like you're gonna need to spend a LOT of time with that old girl.

my '78 took an untold amount of hours, but it rides/runs beautifully and is my main ride. almost every time i stop to gas up, someone walks up to talk about it. makes it kinda slow going somewhere, but nice to see that they are still appreciated and are conversation starter uppers.

good luck with your new project. if it turns, you're on your way!

Sooo, I wasn't able to work on it at all on Saturday and only a short time on Sunday and some today. It would appear that she, Henrietta from here on out, was neglected and not treated well. So much rust. Below are pics of what I have been discovering. When I took the plug wires off there was a green crystalized substance on the right side and less on the left side. I was able to remove the spark plugs without any issues and add some MMO. However, the MMO on the right side ended up coming out a hole in the exhaust. I could not get the exhaust off on Sunday, so I sprayed the bolts with Liquid Wrench and left it until this afternoon. I was able to get 7 of the 8 bolts out. The 8th has a rounded bolt and is going to take time I didn't have today. The exhaust is probably not usable. The bolts used in the exhaust can't be Honda. As I have been looking around at some other bolts on Henrietta, it appears to be mix and match.
