I Know Shocks Arent Made To Come Apart...But How Can I Get These Spring PrOtectors Off. Its Like Trying To Get V! Panties Off So Far. Can I Do It With Stock Kz400 Shocks?

Hi guys, this is on the 74 KZ400 that I've gotten a ton of help on from everybody, and wouldn't have had such a blast riding this weekend if it wasn't for the help I've gotten here. Can't say thanks enough for the patience and help! Hopefully I'll be able to pass on some of the knowledge I've...

So after going through a dozen plugs while tuning the KZ400, when or when shouldn't you bother cleaning the soot off of them. If after one hard sooting are they garbage? I read you can soak them in toilet bowl cleaner...I've just been spraying them with wd40, good hard scrubbing with a wire...

Hi guys, I'm getting a bit frustrated so any ideas would be appreciated. It take 10 days to get different jets and things so if I can get a good idea on what to try next that'd be great. So I have VM30s on the kz400, k&n air pods, and new mufflers, and it's still super rich at all throttle...

Don't laugh please... ;D I got a new set of 24" megaphones for the kz400. It came with 3 reducers, and I'm going to be using the middle one(1.5"), so do I put in the largest one(1 5/8"), and the middle one(1.5") or do I just put the middle one over the pipe and clamp down on the muffler to make...

I have a 74 KZ400D, 5500 miles, has been sitting since 1978, same old fuel and oil was in it....So I've still been fouling plugs and the carbs are set so lean I'm thinking something else is going on. Ignition timing is spot on, so I take a look at the valve clearances. In the workshop manual I...

So after getting spark back, thanks hillsy and Sonreir, I need to start getting the idle under control. The thing I noticed when running it today, besides the crazy high idle was the left pipe got super hot, and it had white exhaust coming out, not a crazy amount but enough. So when tuning the...

So Ive Lost Spark On The Kz400. Finally Checked Resistance On The Coil, Thats Good But Havent Checked For Short From Redyellow To Coil Core, I Dont Know Wahat Is Meant By Coil Core. So I Cheked Points, Nice Little Crackle There And Know Arcing From Condenser. Pulled The Plug And Was Checking For...

Do you guys know if I can use this meter to check if my coil has resistance. I can't pick up any ohms on any of the setting using it, so I'm wondering if my coil is shot or if I need to buy a tester? My brother had this one. I don't pick anything up on the connecting wires or the spark plug...

First ride is in the books! 74 KZ400, mikuni carbs, pod filters...It was sputtering and popping like crazy though. I think it's getting too much fuel, didn't have a chance to check the plugs though, and the mufflers are rusted through, so that could be part of it. It was also revving unsteady...

So my electric start works great but the kickstart doesn't feel like it's catching as much as it should. Clutch out in neutral and it catches some but not enough to fire at all. Clutch in it doesn't catch at all. Clutch in and in gear it pushes forward. Clutch out and in gear and it pushes...

Well I got the new intake boots and mikuni vm 30s on this morning, no throttle cable, and it started and idles awesome, 35 years of sitting and it fricking started! I bought a 2 into 1 throttle cable and once again I'm in over my head. So, I'm thinking the two cables need to be cut and soldered...

Making some progress on the KZ. I haven't cut one thing from the bike so far, being a newbie I don't want to make anything permanent until I spend some time riding it and find out what I like. BUT, I need to cut up the front fender. I'm going to use most of it for the rear tire and a 10-12"...

So I've been waiting for my mikuni carbs to show up, I thought I'd clean up the tail end a little bit. The KZ400 came with the factory tail light and two cool rear running lights. I thought I'd dump the tailight and just use the running lights for the summer. So I disconnected the tailight, and...

Hi everyone, obviously new to the site, and am a little over my head, but was referred here by Brian from Dime City to tap into the knowledge. I found a 74 KZ400D, 5500 miles, and it hasn't been ran since 1978, it's in perfect shape though. So we got the carbs apart and they're destroyed so...
