My ZXR250A Project Log

!!!! Wooot
We have success. I replaced all of the spark plug leads with new lead and she fired up all four like a beauty.
Still a little down on power something isn't quite right but it's a good start.

What is strange though is this temperature situation. Once I warm it up and let it sit for a few minutes the temp gauge goes up to a bit under half. However as soon as I start moving the gauge drops rather quickly down to the top one of the two lines on the bottom of the gauge.

I had a similar problem with a old 4x4 years ago where the thermostat was stuck open and the engine couldn't heat up properly. It caused extra fuel usage and lower power in the 4x4.

Anyone had such a problem with a bike before???

 

Thanks for the that. Hmmmm I have not pulled it off yet but I'm expecting something along those lines.
I hope it can be cleaned out well and the mechanism isn't too faulty. New thermostats are basically non-existent for the bike.

Home stretch list:
Check Thermostat
Fix backfires
Fix power/responsiveness (hopefully just a carb balance)
Fix charging issues (regulator/alternator stuff)
Fix front forks (Leaking)
Re-tap fairings
New Chain
New Sprockets
New Tyre(s)
Safety certificate
Good to go.

Hopefully.
Then I'll need another project bike for my open licence when I'm bothered to go get it

 

So been quite a while since I have updated the thread
So I bought the bike originally intending to fix it up and use it as basic bike till I saved up later on for a new higher CC bike
Unfortunately there is so much more broken/old/dead things on this bike than expected (The rear shock being the latest thing to go)
Unfortunately the bike is just too cool for me to get rid of
So I've decided to screw it and just go ahead pulling the entire thing apart and rebuilding it from the ground up

One positive side is the bike is almost entirely original and gives a good base to go from.
It's gonna take a few months and a few more dollars and a lot more swearing. But fortunately I have plenty of time and the internet so why not.
But hopefully in the end it will turn out to be a mean machine

 

So now I have a little spare time tonight I should get round to adding some pics of stuff I've been doing over the past month or so.

Details:
Carbies (Pre clean obviously)
The rust in the bucket is what came out of the tank after I used a stripping product for the tank resealing (Ewww)
The rear master cylinder I had to pull off and completely recondition (finished shiny product on the bike)
The front sprocket, you can see the guides around the outside appear to have been shattered at some stage
The Muffler on and off (Far too tempted to chrome them)

More photo's to come as I find them/get into the rebuild more.

 

Have had an interesting few days pulling down the bike and finding all sorts of interesting stuff. Got some pics below as well.

So basically were're up to here. Engine is at mechanics, getting valve clearances done, cam chain if there's no tension left and going further in if the valves don't bring compression back up properly. Also getting clutch done while it's there.

I was under the impression that the stater wasn't working hence why is wasn't charging properly until I found this

I'm no electrician but from what I could tell from it's one of the connectors that bring power from one of the three phase's of the stator into the regulator. So I'm gonna need a new regulator and plug. (Chris??)

Next step is to drop off the recently removed front and rear suspension for reconditioning ($$$$) and to find yet more problems.

On another note a question for those out there with more time doing this than I. The VIN on the bike is a compliance VIN. However there's no compliance plate?? Anyone know why this is? Was compliance done before the introduction of plates?? I don't know?
