1975 GL1000

#1

Post by cfairweather »

I just stated a new project, a 1975 GL1000, and started disassembling the engine today. I figured this engine would be a good one because I bought it from a man that had it stored in his garage. Obviously, it had been outside...

What a pity. I wonder what the bores would clean up like.

I love your optimism but the rust is very severe and not repairable. The good news is, there are lots of good parts on this engine and I have another spare. I am interested in seeing the crankshaft.

That sucks! I pulled the heads on a 1100 that has been outside for 5 years and it wasn’t that bad. But this is west Texas. Probably had more sand in it than rust.

I finished disassembling the entire engine this morning and it was in excellent condition. All of the bearings were in great shape and even the pistons were nice. I also got the heads off of Engine #2 and there was some rust in the cylinders; however, this engine is usable. Engine #2 had a broken belt and a cracked/bent pully wheel. The valves were very rusty so it looks like the belt broke and the owner parked it and let it collect moisture for years. I will use parts from both engines to make a good one.

I'm with Liam, clean up the cylinders, a good honing and maybe a nice surprise? New rings? Canuckxxxx used rings from an early model Chevy Tracker - purchased from Rock Auto, standard size set in his 1100 rebuild. He did mention he would use the one size larger if he did it again. As long as the ring will float nicely in the ring groove, can adjust the diameter to suit.
Another fellow mentioned that Hasting rings can be used as well. There is a post on one of the threads about this. Good luck.

The rings you purchase should be the same size as/fit the bore that you have. Going bigger would distort the ring and it would not seal correctly.

Thanks Robin and I agree. I will probably order rings from Saber Cycle because I like their design. These rings have a thin wire in the middle of the oil ring and it prevents the ends from overlapping. I used these on a 1975 GL1000 that I restored a few months ago and was very happy with the results.

I just finished opening the cases on engine #2 and it is in amazing condition. I typically replace the primary chain when I go to the trouble of opening the cases, but I am not replacing this one because it is almost like new. I am going to add a primary chain tensioner from a 78 or later. Not sure why Honda decided not to put a tensioner on the early years.

one question, I see that you all know how to handle the engine as if it were a simple thing and with incredible results. but where did you learn? do they teach it at school? I am amazed every time at how good you are! Do these jobs, even total restorations, with disarming ease and simplicity! In Italy I don't know of any private person who is capable of disassembling, repairing and closing a GL engine.

Paola- Thank you very much for the complement and let me first say I am not a professional mechanic or painter. I do this as a hobby and consider myself as a "Jack of all Trades - Master of None." I am 65 years old and I started riding motorcycles when I was 8 years old. I also started tinkering with bikes, cars, TVs and other things at an early age. In the beginning, I was great at taking something apart, but not so good at getting it back together :). My dad was unafraid to try anything, even if he knew nothing about it, so I learned a lot from him. He built our home and many other things. He also owned a TV shop and I worked there as a teenager. This was a great experience and I learned a lot about electronics at an early age. My parents let us grow up without the fear of failure and encouraged us to try anything. When I was in high school, I had an auto mechanics class and I was able to rebuild an engine. While I was in the Air Force, I taught myself computers, networking and programming. This allowed me to have a great career in IT for many years. I am now retired, but I still have a church software ministry and a web site where people can download my software ( www.ChurchWare.com ). To be successful at anything, you have to be a good problem solver, have high standards and be tenacious. Try doing something you don't know anything about and remember that failure is part of the learning process. Thank you again for your kind words.
Cedric
