There's a different part number for the J1/2 and J3 stanchions and brakes. The early ones have an A after the number, the J3 and R2 part numbers are the same with no A.

Do a search for brakes using the search facility above and you'll find other threads discussing this. You need narrow calipers to work with the standard front end as Pigford said Pretech, Billet are thin enough too, and some of the H****a Nissin ones are narrow at the back as well. Your average four...

There's more than a fighting chance you'll find it in the sump if that's where it's gone.

Okay so it might be off something else and be the same size.

Garn - further to what Colin said there's no way the arm would bend through heavy braking something else would give first. It's differently finished as well it looks like a much better casting - maybe it's some kind of pre-production one because it's not really likely to be off something else with t...

The first thing is the main is way too big. Try and get hold of 115 mains and then see what's happening. My brother's bike has 26mm Z1000 carbs on it and he thinks there's 115's in it with filters and a Yoshi pipe. The 750 engine was just a bored 650 but you'll have more compression with the Wiseco ...

Yeah you're right you need to go up on the pilots it's too much air you'll get low down not too much gas. The Ledar corrector screws blocked off part of the pilot air passage to compensate for the increased flow through the filters. That would be 17.5 to richen it up based on a 15. If you've still g...

To be honest the last time I changed my A1's fork oil they were completely apart. It's easier to measure the level with the leg off the bike anyway because it's easier to get it vertical and the bars aren't in the way, and I think you can get pretty much all the old oil out if you leave them to drai...

30 years old or not it will help to have the correct amount of oil in it. A well set-up zed900/1000 handles surprisingly well as long as you don't get over-excited.

The factory manual says that 426mm is the measurement from the top for an A4 okay, but it should need 170-178cc per leg. You measure with the spring in okay, but are you sure you had the front of the bike jacked up enough to be sure that the forks were fully extended? 375cc was a bit too much but 28...

If the set-up's the same as the other Zeds the best way to do the float levels is to get a tool made up like the one in the manual with a tube that screws into the bottom of the float bowls. You can then measure off a point on the carb.

Main jet sounds very big based on what you say is standard and a Marshall wouldn't flow that much extra gas. It's very hard to get a bike with individual filters to run properly low down without Ledar air corrector screws which no longer exist, and I'm assuming they aren't already there. The Dynojet...

It was the local VJMC that organised the Ballymena show you were at Davy.
