kz750 twin questions

I have been looking for a project bike and came across a 1980 kz750(T) 2 cylinder in running condition. Its supposed to run well. I have seen it and it looks old. Probably a good restoration project. needs new speedo, tires, chain/sprockets, paint, etc.

Are the parts on the twin models interchangable with the kz650 and 750 4's?(like speedometer and frame parts) Are parts for this model going to be difficult to find?

The owner is also selling his 80 kz1000. Same kinda thing, supposed to run well but pretty rough looking. He is asking $800 for the twin and $1000 for the 1000. I am looking at the twin because i'm only going to use it for transportation on a small island(i have an 86 zx900 for the long hauls) and i have never rebuilt a motor, figure 2 might be easier than 4 when she blows. Should i consider the 1000, is it that much better, and are parts alot more available?

I talked him to $650 on the phone for the kz750twin. Does that sound like a good price? It needs work but if its running that sure makes it easier.

Any advise for someone starting their first restoration?

I've also been keeping an eye out for a KZ650 or KZ750 twin to buy, so as to keep the miles low on my vintage bike. Would like any input from the forum!

Depending on condition, I'd try for the 1000. Parts availability is much greater. I believe the '80 is the mkII version, and that engine just went out of production this year in the KZ1000P.
The aftermarket offers virtually nothing for the 750 twin. The 750/2's aren't bad motorcycles, but they were never very popular. Also, there never was a 650 twin. KZ650 and 750/4 swap a lot of parts.

Having a 750 twin, I know about the only performance thing offered for them on the aftermarket is a couple different pipes and the generic carb mounted filters and stuff - and that's it. Regular wear parts are readily available from generic retailers and you can get the wierd stuff from kawasaki. The great thing about these old bikes is that you don't necessarily HAVE to replace the parts with OE parts. the only original exterior parts on my bike are the headlight, side panels and tank. turn sigs, stop lights, seat, fairing, and electricals are all new.

But speaking from my own experience they are reliable and fairly quick and you get a lot of looks and thumbs when you rebuild it right. I went with the vintage 750 because it's my first bike and I didn't want to kill myself on a liter bike and I wanted decent (50 ish) fuel economy

The 1000 is a better bargain... far better.

The KZ1000 is a sought after bike - the engine is incredibly rugged and the bike produces excellent power. It is easy to work on and you can get just about everything you'll ever need for it. There were thousands of them sold, so used parts are plentiful. You can get performance parts as well - even punch the motor out to 1500cc if you want to spend some serious money. A marginal running kz1000 will fetch a minimum of $1000 and as much as $1500 depending on the year/model. A nice running decent looking 1000 will fetch $1800-$3000 depending on how nice.

The 750 twin is really a stepchild of the range - many of the engine parts are unique, some of them are difficult to impossible to get. For example the intake manifolds for some of the years are unobtainable. Market value for a good 750 twin is only $700-$1000 for a good running one.

The manuals come up on ebay from time-to-time. You need to be patient.

With ebay you can enter a search, then add it to favorites. When you add it to favorites you have the option of having ebay email you when an item matching that search criteria is listed. This saves you going out there every week and looking.

Ive got an 80 750 twin with 2500 miles on it. Ive also got a KZ650 1978. The points are the same ( only one set for the 750 ( though) most things are different. It looks like a different frame, too. The 750 is closer to my 1100, same tire sizes, The carbs are the same. Im cutting down on bikes so, if anyone wants the 650 or 750 let me know! I will keep the spectre and the others in my collection. I would go with the 1000, though. I like the extra ummph.
