Hi guys, new to the site. I have hopefully stuck on some pictures of my Kawasaki Z250 as I bought it and as it is currently. It is getting the usual list of mods inclucing cut off rear frame, replica Ducati tail section, smoothed frame, pod filters, loud exhaust, tingate clip ons, etc. I have never heard this thing go, it hasn't been ridden in ten years. Next is to mount some rearsets, get it running to make sure everything is right then the big strip to paint and rebuild everything. I can't find much evidence of kwaka cafe jobs, is there a reason for this? I'd be interested in any comments or sudgestions.

Already looks about 2000% better!

All the lines work nicely. Have always loved the SS tailpiece.
What you going to do about the battery?
Glad you've gone for clip-ons too.

Nice one :)

the work you've done has worked wonders, i cringed at sight of the first photo. let me be the first to say, if you haven't heard it run yet how do you know you're not investing time and money in what may serve better as an anchor than as transport. some here will agree that you'd be better off waiting on the rearsets and what not and make the damn thing run. for one i find it helped to see and hear my bike run right in it's stock form so when i started making changes i could tell that my mods were the source of the problem. right now you are adding more variables that you may have to sort through on a bike that you are unfamiliar with. just some food for thought...cheers

Wobbles- Thanks for the compliment. At this stage engine will be black or gunmetal. I'd like to polish the side covers but need a new right side as it has been damaged and repaired...badly. Wheels will most likely match engine, black frame and kwaka green for the body work. Clip ons were the only way to fly, a bit hard to find the right size but they look way better and avoid the imminent ridicule of clubmans. My battery will either be twin six volt units in the tail or a single twelve volt unit under the swing arm just behind the gearbox.
Snorkelfork- I take on board what you have said. The bikes history is known thru a friend so I shouldn't be in for any huge suprises mechanically. Rearsets are my only mod before I get it running only because I want to check riding position so it is actually rideable. I'm anticipating carby problems due to lack of use, lack of mufflers and podfilters. I'm lucky enough to work with a fella who is a tuning guru that can help get it sorted.

OK guys, time for an update of my slow but steady progress. Below is a shot or what is left of the rear part of the frame. You can see where tabs have been removed, still more to go tho.

Relocated horn.

I got bored one arvo and polished the switchgear. This is what can happen when you wait too long for parts from ebay.

Billet rearsets mounted up. These will be polished rather than machine finish when its all done. Gear linkage is from an RZ350.

My "mufflers" are made from a 90 degree stainless bend that is cut, blended and polished. I hope that this style of muffler will reduce noise output by half a decibel or so.

Steering damper mounted to lower triple. No bracket on the frame yet as my mig went on a holiday...

Engine is nearly ready to fire. Waiting on carb diaphragms from japan, then just have to mount the battery, refit wiring and go for a test ride!

looks good, any shots of how you hooked up your brakes to the rearsets?

Zman, no shots of the rear brake setup as it hasn't happened yet. I have made the bracket for the master cylinder but still have no welder to fit it to the frame. The master I am using is from a zzr600 and it fits forward of the rearset in the triangle part of the frame, I didn't have enough room to mount direct to the rearset which would have been neater.

Another update on my progress. I have some time off work and a welder again so things are getting done. The rear brake master detail and steering damper can be seen and if you look carefully the ingnition switch is under the tank. I've also fitted a rear hugger type guard to the swingarm, it's a bit streetfighter esque but i'm keen to keep the bike as uncluttered as posible. Only fab work left now is two seat mounts, exhaust mounts, and battery cradle under the swingarm, should get to ride it by friday! I got hold of some spray cans and tried out the paint scheme too. Let the opinions fly.

You stole my rear fender plan. I 've had the fender for 2 weeks, just haven't had a chance to stick it on the bike. Looks good. I too, like the color.

Front fender is original but has been remounted around three inches further back around the tyre. The rear hugger is from the front of another kawasaki, a larger KZ of some description. It has a matching profile to the front guard but is wider.

Man that is looking sweet.

Although a prefer the look of drum brakes it's kinda neat that such a little bike like that has a disc brake on the rear no less!

Is that a Ducati two piece style seat? I like how they have a separate seat pan.

That thing is going to be LOUD!
Have you given any thought of putting cone/Dunstall type mufflers on it? J.C. Whitney sells the shorty ones(18" long) pretty reasonably($43.00 ea).
They are the Shorty Seamless Megaphone (cone tip)Muffler Part# CBG017567

The extra long Dunstall type Reverse cone 27 1/2" long are quite a bit higher at $70.00 ea. but come with a mechanical metal baffle core which IMO is a lot better than one you have to keep repacking.

Really your bike looks so much better than the first pics the transformation is simply amazing. In the first pic that could be a bike I could just pass right up if I saw it for sell somewhere,but after your work/mods I would definitely have to check how much they wanted for it and see if I had enough uh..Allowance money to get it.<img src=icon_smile_big.gif border=0 align=middle>

I think that is basically the same bike as the GPZ305, which was sold here in the states for a couple of years. Kind of a slightly mor modern CB350. I see them on e-bay occasionally.

I had a bit of a scout around on the net and found the GPz305 was a descendant of what I have a KZ250A. The later bikes having belt drive, monoshock rear and integrated bodywork. Should be a good source for an engine upgrade as they are reported to do over 100mph in standard form. I might take my bike to the speed trials to see how fast it goes on the salt as I only live just down the road from where they are held.

The tail piece on my bike is in one bit, not two and is a replica of a mid seventies Ducati 750SS "green frame". As for mufflers I will have to do something if it is too loud or just sounds crap as it is.

Nice job so far,Hoop. Is that a Bron-Moto ducati seat? Wish I could weld like that.. I got my cb250 frame powder coated before grinding the lumps & bracket remains off and now have highlighted my poor prep.( pics coming soon, Wobbles).
Looking foward to see your rear brake setup as well.
