Some parts have arrived! Work is underway. :-D[img]
-
where did you get the subframe will?
-
are you rich :-o
-
How the hell did you get your mits on all that "unobtanium" ??? :-o
-
are you rich :-o
:lol:
Might be if it wasn't for bloody motorcycles! Hubs are made by a local company to me, Talon Engineering. Tank made by GMX, who are also making the radiators.
Subframe is AC.
Really lucky with the Shock, came from a local ex rider who had it in his shed since 1990!

I thought I was going to read another "Destry Abbot ex-race bike barn find" !!!

so my comment should have been 'were you rich before you bought that lot' lol. that is some very nice stuff, green with envy, excuse the pun. cant wait to see this build progress, its looks like its gona be good. is the bike to be riden/raced or a show piece?

Its being built to be raced, hope to race at the Vets des nations at Farliegh Castle in Sept. Spend most of my time on Tarmac, Roadracing these days but looking forward to getting out on this!
Not sure how far to go with the Motor, all sound, usual 3rd gear wear so will renew those, bore looks good, no play in big end. Tempted to just renew the worn gears, new piston, new mains and seals, and maybe a con rod. Going to leave the motor pretty standard but have a procircuit exhaust to fit.
Is there anything else I should be looking at Motor wise?
-
i dont have major experence with kx500 (i am rebuilding 1 now) from what i can gather the the big problem is the con rods snaping, so defo renew it with some thing good, not wiesico (made in china now). kips mod on here looks easy and worth doing, pm kawrider hes got some speicial bolts. i am having my crank dynamicley balanced by criss applebee engineering, i think vibrations are the big killer with big bore 2 strokes so that should help, also using oem gudeon pin as it is lighter than a wiesico pin but still using the wiesico piston as it lighter that oem and with the window mod its lighter still. i am hoping that by reducing vibration, and mass from the piston end of the conrod it should reduce the load on the con rod. all the above is found from this site, just though i would save you some time and let you know what to look for
all the best

Thanks John, that helps, didn't know about the rods breaking, looks like the original in mine. I think Hot-Rods make a kit, are they any good?
Hard to believe wiseco are having stuff made in China!? Surely they must knoew better.

i have had mixed messages about rods. some say theres no problem others say there is, about 50/50. i currently have a bent rod. i was full bore in 4th or 5th when i felt a little hesitation/weakness in the engine so in with the clutch and kill switch, quick sticks. stripped it to find the conrod bent so i am thinking there is some truth in this weak conrod thing. i am going to air on the side of caution as my motor will have cost a ?1000 + when done so i am gone do everything i can. hot rods are not good so i hear (never used 1 in anything). prox were the 1s to use but there not making them now (my still find one on the shelf). i purchase an oem from corby kwak and will be having it fitted and balanced by chris applebee's. i am going to ask if he can do the piston port for me if your interested in doing that, i think it has some good benifits, ie better top end cooling and lighter piston. my aim is to have a reliable motor with good usable power for mx not the fastest 500 in the world. i dont think thay need any more power for general mx use, i think thats where you want to be too?

Some progress!
-
stunning!!! is a word that springs to mind :-o
-
That looks gorgeous! Looking forward to watching the progress. Keep up the good work.
-
MORE PROGRESS :x :x :x :x :x :x
-
Not Yet! I have the engine cases back but am waiting for some new gears. There is something VERY special being fabricated as we speak. Dont worry as soon as it takes shape I'll post it up!
-
what can be VERY special? i cant wait to see it :-D :-D :
-
nice project, can't wait to see the finished product.
-
I am new to this site, but not to the 1989 KX. I had a 89 KX250 years ago and recently picked up a 89 KX500 that has been well used. Looking forward to your writeup. Great job!!
-
Hi Guys,
To anyone thats looking for progress, there aint none! :?
Still waiting for the new gears to arrive. Also when I stripped the 46mm right side up forks one leg was beyond repair. Replacements have arrived and the rest of the motor is all ready to assemble. Theres also been a delay on the new swingarm. I'm hoping to get everything complete before Roadrace season starts in March as I wont have any time at all then.
-
nice project.....
-
How are we doing on this? Very interested!! :-D
-
That tank is awesome. Show your special bits :-D
-
Just a few pics of the forks and Radiators before I head off to Spain testing the Road bikes.
-
I spy a Leo Vince :-D
-
Im digging those radiators...

Hi Guys,
I've been away for a while. Sadly I highsided my Fireblade at Cadwell park race cicuit and sustained a shattered pelvis and hip back in June. Hospitalised for over 3 Months. Docs said I wouldnt be walking for at least six months but thankfully now way ahead of schedule with the recovery. More importantly I can now continue with this project! Watch this space! :-D

Will, sorry to hear about the spill at the road races, i hope your on the mend. ( I wondered why i didnt see the bike at Farleigh). The bike looks great, its come a long way since i sold it to you! I am also building 2 kx500 `89s that will probably look very similar to yours in terms of trick parts,... except for 3 things. I am putting an alloy subframe on "with an integrated airbox" to give it added strength. Also, i found some brand new / never used WP 4054 multi adjust forks that i want to put on them. Lastly, i found a local engineering shop that builds 2 stroke cone pipes, they reckon they can build a couple for mine. ( has anyone tried to buy a brand new "works type" Procircuit pipe lately??.....impossible)
Once i have some decent pics/progress i will post em up.
Jon.

Jon.
ive heard that people have bought the plated pipes then stipped the plating off then burned the pipe with a welder , and that makes it look like a works pipe

Hey Jon,
Good to hear from you.
Sounds good, I never did like those WP forks tho.
Send some pics when you can.

Good Grief Man! :-o
Very sorry to hear about your accident. I had my right hip replaced a while back and have to do the left side also...
I know it was pretty bad the first week after sugury, and my pelvis wasn't fractured...
I'll put a good word in for your complete recovery.
Keep the faith and keep us informed on the restoration of yourself and your Bike! :-D

I think your right, the WP forks are probably not as good as the 46mm KYB conventionals. But i have yet to find an alternative, Ohlins didnt produce forks for the kx5 back then(or at least i havnt seen any) i am trying to do something a little different.
-
Well worth the wait!
-
:-o Thats cool.
i want a coke bottle swingarm for my 88 cr250 , but the problem is that it costs $1200
unless i win the lottery in the mean time....
