    1978 gs550 Timing plate max out rotation

    Having the same problem with my '79 750 with a picture here - this is what you're encountering too, right? Totally at a loss as well. I have had the head off to hone the cylinder and lap the valves so valve timing is confirmed to be correct, but don't the points run directly on the crankshaft...

    Question on Points Ignition - maxxed out?

    Yeah it'll be the same price for the knock off as new points+condensers so I'm thinking I'll skip the headache of messing with points.

    Question on Points Ignition - maxxed out?

    Jeez a twisted crank sounds like it could drive someone insane checking valve timing... Waiting on some more shims to be shipped to confirm, but it seems like .15mm+ of valve opening would sure cause some loss of compression. I saw some knock off Dyna Ss on ebay for ~$30 - might be worth it...

    Question on Points Ignition - maxxed out?

    Valve timing is good. I set it when I did the cylinder and valve lapping. Wouldn't that effect all cylinders anyway?

    Question on Points Ignition - maxxed out?

    Hey y'all I've never worked on a points ignition system before and tried to set the timing on my '79 750. I think the timing is maxxed out and I just wanna confirm. Some quick background on the engine: The bike had been sitting for at least 5 years before I got it. I saw it running very, very...

    Brake Caliper Piston Wear

    Ok the pistons look quite a bit better after cleaning up. The pitting on the inner one is still there but I'll run them for now and see how they do. I talked to a couple of spots in town and it sounds like it'll cost me as much to get the rubber crimped lines locally as it will for me to build...

    Brake Caliper Piston Wear

    Woah thanks for that awesome write up I'm gonna be reading the rest of those "popular technical info" posts over the next few days. I might go that route - seems like a piece of cake compared to the bending/flaring/routing nightmare that I've gone through for automotive brake lines. It's gonna...

    Brake Caliper Piston Wear

    That's pretty eye opening. I'll have to find some replacements/learn how to make em. That totally makes sense. I always wondered where the gunk in brake lines came from and I knew it was hygroscopic, but I didn't realize that's what caused it to gunk up.

    Brake Caliper Piston Wear

    Definitely gonna replace the seals. This bike has been sitting for quite a while and the boots are totally blown out. Looking more into the seal groves on the caliper, there's quite a bit of hardened crud in there. Sorta looks like somebody tried to seal it up with something that reacted poorly...

    Brake Caliper Piston Wear

    Thanks for the tip! It's hard to find pictures online of "acceptable" wear - all my searches only brought up comparisons between brand new and very badly work.

    Brake Caliper Piston Wear

    I'm getting around to the brakes in my 79 GS750 and honestly they didn't seem as bad as I expected. Not much rust on em even though the boots were mangled. The pads were down to the last mm and the rotor is well below spec. That's all stuff that's pretty straight forward for me to diagnose...
