My GS500 Story

[Bucko]

Wow, that's a nasty case of goats my GS had it last year and it wasn't half as bad as that, flushing the engine through was a nightmare as well, just as you start to think it clearing, it shits a load more bits of shredded magnet! Not a hard fix tho as you found out, I used the exact same method to pull the fly wheel, beats buying an un-needed and expensive fly wheel puller.

I see the flywheel mice have been at it again :d

Is it not part of the service schedule or your own schedule when you have an older bike?

Yeah i can imagine it's going to take a while to get it all out! I have purchased a magnetic sump plug which should help me out!

Yeah the hungry little buggers! Hopefully they don't need feeding ever again

Yeah it appears that way Bill, i've added it to my maintenance schedule now haha.

So finally got started with putting her back together, hopefully get it finished this evening.

Replacement flywheel


Replacement magneto and gasket surface cleaned up


Cleaned the cylinder head mating surface, shes been running really lean even though i'm running massive jets (can't remember what sizes, think 62.5 and 145 mains but not sure on the 3rd jet) so going to raise the needle and see if that helps. Should have checked the plugs before as it backfires off throttle a lot.


New head gasket on


I've torqued the head up to 40nm, and the cam caps to 10nm, then timed her up but there doesnt feel like theres enough compression so maybe a tooth out from cams to crank?

Also my chain tensioner is shot, it wont compress and theres no slot for a screw driver to back it off as its fubard!!

Seems like my year old motobatt is knackered, but i put her back together yesterday and she runs

Missed the sound of her, although i expect my neighbours haven't! need to MOT it after Christmas and go for a ride
