Yvon DuHamel whips what's supposed to be a standard Z1 (apart from the fairing and tail) around the Daytona oval in 1973 at 160.113mph. Awesome. No sound unfortunately :sad: 3 Z1's broke 52 speed records in 3 days. http://www.youtube.com/watch?v=dl8v-0VqKSw

HI, I have a 1980 kz250 that I put a K&n air filter on.(one that bolts right to the carb) They disco-ed the orig. air cleaner. I am thinking that It doesn't neccaserly need rejetting, but I'm almost sure it needs some adjusting, it is hesistating and back firing a little. I have read that on...

For those of you who aren't familiar with the situation. My 81' KZ650 CSR is giving me rpm troubles. When i'm in high gear or any gear, except maybe first, the engine accelerates like the clutch is bad. I just replace the clutch discs last weekend and the old disc's looked fine but I did it anyway,...

I just bought a 1980 KZ750 as a project, and After it warms up, and you take the choke all the way down, the engine studders when trying to start up from a stop. It will simply not accelrate with any briskness until it gets above 2500 rpms, at which point it takes off. I can ride it with the choke...

Could anyone give me detailed instructions on how to adjust the carbs on a 1980 KZ650? I know its running rich cause it has been fowling out the plugs. (left side inner plug espesialy)

Hi all, I just bought myself a 1980 KZ1000E. I love the bike so far, runs great and is really quick. I noticed when I took the bike out for a test drive that there is a spot just off centre when you are turning left where it seems to stick. It doesn't affecct the steering and there is nothing...

Hello, I recently "rescued" a 1980 LTD 750t . I am in need of a sevice manual. So far i have tried the links in the sticky at top of forum, sent numerous e-mails, no luck so far. I have found manuals for the 4 cylinder series,(Clymer M450), however i am new to engines, and the differences...

After exhaustive tinkering, I've given up and declared the bike driveway decoration for now. It turns over, has compression, has spark, ran fine when on, timing is set, gets gas, new plugs, new battery.... no ignition. So i'm thinking something is wrong with the pilot circuit in the carb, or the...

Anyone know if those bikes share the same frame. I'm looking to purchase a sissybar for the 650, but the 550 sissy bar is the only one I could find one for and want to know if the frames are the same before I buy.

Have the most amazingly basic question, as I have never owned nor ridden a bike before. I bought an LTD and a Spectre, both 82 750's as winter projects. When I turn key on, lights go on, and when I press starter button on handlebar I hear solenoid clicking. However, starter doesn't turn over. I...

I see the word tomcat pop up from time to time when people are talking about parts they have for a tomcat which is a 89 zx-10. I see it also on web sites were there are pics of 89 zx-10's. I own one so would like to now what the phrase stands for???? IF ANYONE WOULD KNOW, LET ME KNOW...

My brother has a 1989 ZX-10 and it is having a problem. The symptoms are: - The clutch lever is very hard to pull in. Almost like the clutch will not disengage. - The bike will not roll in gear with the clutch lever pulled it. - The engine will not turn over. The starter tries to turn the...

eek!

KZs are notorious for snapped clutch cables, usually at the handlebar clutch lever. Repeated clutching wears the cable, right at the slug where it attaches to the cable. The good news is that that cable will usually start to fray before it snaps, so you get a chance to fix it before it leaves you...

i have had this particular machine since jan 1987 and have kept it in decent conditon since then i have not driven it in two years since it would not start, I have found that the ballast resistor is defective. i am not awre of what the stock ohm values are for the primary circuit and as the...

Has anyone used JC Whitney for parts, etc? I am considering ordering a new set of sprockets, front and rear, from them for use on my KZ650H3 CSR 1983. They seem to have the right parts, etc. I'm just curious if they are worth saving myself money. My local dealer can order the sprockets, but...
