I rebuilt my 1990 FZR600 from 2021-2023 and found so many issues. Lots of electrical issues that needed a ton of research. It runs now and is nearly ready for the road again come spring. Enjoy your journey!
We did the same with an 81 Suzuki GS650gl but eventually ended up selling it. Liked that bike so much that we got a 77 GS750. Turns out there's two of us, so in came another GS750. Needless to say, we've got enough project bikes sitting around, so we're leaning towards actually selling this one as a running project.
Nice. This one has just been sitting as the Suzuki GS750 restoration has been the main focus. But with that last video out, maybe we'll think about doing something with this again.
On something that has not run in a long time be cautious - beside checking there's oil, you should always check the airbox, besides visitors the air filter foam crumbles and will get ingested. Also squirt some oil into the horribly dry cylinders before cranking, lube is always your friend.
Good tips and advice, I did peek in the air box before cranking it over to make sure it's empty. Eventually I did spray the cylinders and let it sit for a while to work it's magic
Dan and David, Did Dad pass you the suggestions from our friend on your side of the country, Forrest Kerns? He has a lot of experience with these 600s.
Yes he did. We will be sure to reach out and ask him questions as we dive deeper into this bike. Thanks a lot for watching and for all the comments and help.
Check the pilot jets aren't clogged and that the carb idle adjuster screw isn't set high - but, as you say, there may be a vacuum leak, split rubbers or something - thank you - good stuff. Bet those psi readings have come up !
Thanks! I definitely should have checked compression after running it, I'm sure it freed up the rings. I took a closer look at those boots and they definitely need to be replaced
Bike didn't come with a title, but since I live in New Hampshire I don't need it for anything from 1999 or older, I can just use the bill of sale from the auction.
Change the oil and filter. Check fuel tank for any rust so you don't have rust going into the fresh carbs. Wouldn't hurt to let some oil sit in the cylinders and turn it by hand since it's super dry and can help loosen piston rings. Unless there's anything else wrong with it that's probably good enough
