I just acquired a K0 with an early dual disc upgrade. Happy to sell the complete wheel and any parts you may need to complete the project.

Great find. Reasonably early sandcast and numbers are close enough to be a match. Nevertheless, there is a lot of work and expense sitting in that trailer. All the best  :)

Just found this bike yesterday. The owner passed away and the family was going to scrap the bike so I took it not knowing what I just fell into. Saying it's rough is an understatement but I'm hopeful. I have attached pics of the bike as it sits and of the frame and engine numbers.

Tips on Board Functions / Re: Oil filter housing

Hello,i am fairly new to the group. I am searching for the most accurate sand cast oil filter housing available. Who makes it and where do i get it ?
So looking for mirrors. Are the Yamiya copy of both item accurate ?
Any help appreciated

Welcome to the group.  i haven't participated much the past few years and my knowledge of most accurate repro parts available isn't up to date, but to my knowledge and experience no one then was making an accurate reproduction of the housing.  i know Yamiya was offering these filter covers but the last i saw of them they were a rough cast finish which was not the factory finish that was not highly polished.  Attached you can note the filter cover that came with my F232 bike.  Finding an original cover will probably take a lot of searching.  You could always look for the early finned version without web reinforcements on the inside, or any finned cover and knock off the fins and finish the final turning in a lathe which i've done a number of times or do the same to a Yamiya cover assuming they still have a rough cast finish.

Please do follow up on the forum for the benefit of others with what you finally settled with.

Welcome. You will have a better time sourcing correct parts, given the higher VIN, than if was an early bike. My only advice is don't fall into the trap of using repop parts. There are still plenty of correct parts out there you just need to persevere in finding them.
The site is a bit dead these years but the information here is as good as it gets KP

Review of VIN'S For Directory / Re: Frame & Engine Number Spread

Well just an update on the bike Ive been offered - there was a digit missing from the VIn - shazzam, it was a 9 missing from the front of the numbers, so its a diecast bike. Damn.....

hi ya'all,
So I was in New Zealand recently and a local seller of some [apparent] renown was selling a sandcast for $80,000 NZD. The frame number and engine number were 6000 numbers [give or take] apart and I suggested that he should make a note on his ad that the engine wasnt the original engine. Well all hell broke loose and he accused me of calling him a  liar, cheat and crimnal and eventually he blocked me from Trade Me [the local sales site]. Subsequently he changed the ad to make comment that the guy he bought the bike off [a renowned US restorer who he wouldnt name] had gotten a Certificate of Authenticity from the 'official' Sandcast Authority' certifying it was genuine.
While I didnt claim nor infer it wasnt genuine, all I had done was suggest [so that he couldnt ever be accused of misrepresentation] that the engine likely wasnt the original. Its currently for sale for $60,000 NZD without NZ registration or much else for documentation.
In one respect I hope he gets his $60,000  as its increases the value of my collection through the roof, but at the same time I could see a few years down the road a disgruntled investor being mad as hell when he cant get his money back because the engine isnt the original one. Yes it may be a 'genuine' sandcast but where does one draw the line as to its true value. I guess the market will tell us the answer to that!

I had a look at the listing and also asked the question about frame and engine number. Lots of waffle and not so helpful info provided by this guy. The bike, IMHO, isn't worth anywhere near that amount although I don't know the NZ market so it may be bang on the money. To be honest I think the restoration isn't that good, lot's of incorrect parts fitted. The fact he hasn't started the bike is a worry, but then he may have treated the internals so they don't gum up over time. Anyway, good read and love his responses. KP
