Mine's running actually
Doing a bit more after work... got an exhaust pipe that was meant for the ZXR but never made it on.
Cut the stock pipe off and weld the new flange to the link pipe. Problem is, the outer skin of the link pipe is stainless, with a smaller steel pipe inside, which is very thin. Rather than weld from the outside, I will try from the inside first.
The stainless will weld fine to the mild steel, you just need to paint the welded area so it won't rust.
Finished off the welding on the exhaust pipe today - the inner mild steel section was broken inside so the pipe was loose in the stainless outer... welded the stainless to the adapter plate supplied with the pipe and now it doesn't leak. Probably need a new gasket for the link pipe but not going to bother... I had other running issues to find.
Went in and balanced the carbs, found a dodgy repair on #4 vacuum plug, so it was leaking. Replaced with a spare from work... as for the balance... I'll let the picture do the talking
Have to do some fine tuning of the mixture screws again (too hard when the bike is hot). At least now I know the radiator fan works, I'd never heard it run and saw it running - it is actually working, just quiet.
Still waiting on the rear shock... like riding a pogo stick!
Rear shock arrived and fitted. Pulled apart the knuckle and serviced it. Bearings ok except for one which was a bit dry and stuck. Managed to free it up and get it full of grease, it kept jamming... I had to keep cleaning, regreasing and rotating it until it finally freed up enough to be serviceable. It was that or leave the bike and catch the bus home.
Shock arrived pre-configured and after a ride home I don't think it needs any adjustment for solo riding. For 2-up I will need to add some preload adjusters or something to the forks. Sag feels nice and even.
what are the details of the rear shock?
I'll be after one for my son's GSF250 in the not to distant future..
Provided that is, that the replacement engine we bought works out ok once we get it installed.
I bought it from wemoto.com.au
No wrecker in Sydney had a standard seat. Found one on buyee for $50 so I bought it. Naturally postage from Japan was outrageously expensive at $115, but it's worth it to not have a sore bum all the time. And it's still cheaper than a new OEM seat.
New seat arrived yesterday. Put in and took it for a ride. Immediately binned the old one. What a difference! Can't believe I put up with that thing for so long.
