again, great information, thank you. As you stated, the frame and engine numbers confirm the bike is R2J and in fact the carbs are what they should be:
FRAME: MC181004427
ENGINE: MC16E1035537
CARBS: TA20AA

It's a great relief that I was wrong in thinking that the original engine had been replaced with an older version, like you and the website Frame and Number Reference Chart itself shows- all motors start with 16E. Phew.
Also using the information on this site I was able to confirm that this bike has not been de-restricted which I think is great and interesting that someone would put on some performance pipes yet not de-restrict it...but then again perhaps it was simply a law abiding previous owner in Japan. The auction I got this bike from was selling a collection of a deceased Florida resident, a multi-millionaire who had 200+ bikes and I think he imported this and never got round to doing anything with it.

Blue/black wire still in place.

I appreciate and support the advice on sticking to OEM parts- if they can be found- which I am sure they can-I just don't know where to start. I need to start collecting the basics such as carb, brake caliper rebuild kits, fork seals etc- I would be grateful if anyone could point me in the right direction as the only creditable supplier of parts I've found is Tyga, they have a lot, but not sure they have everything.
MUCH appreciate pointing me in the right direction for the Manual. It's fantastic.
Relatively low mileage on the clock.....11,335km

Yet worn out peg rubbers.....hmmm.

New case needed
