By the time you are here in TO, it will be 5700 CAD ..... the shipping, handling etc. will kill any deal. It's terribly ineffective to ship one bike from overseas. It starts making sense from 3 up, container obviously being the bang for the buck.
Anyways, in GTA Nuak is your only choice really. He was in Japan weeks before the disaster hit. A person I know finally reached him as he was looking for a bike himself. Whether his spring container will arrive or not in time is hard to tell as many things have been effected by the disaster as you can imagine.
I personally have bought two bikes from him in the last 3 years, both time in fall and both time the price was right. Everytime I buy a bike from him (or any other importer for that matter) I assume it can be a lemon. I carefully go over it and base my negotiations on what I see. One unknown is always the internals of the engine, but that is part of "rolling the dice". It's given that you will have to take carbs apart, replace chain, sprockets, tires, rebuild brakes and replace fork seals. In most cases, the tank will have to be coated with a liner due to years of rusting. Both bikes I have bought from him were in very good condition, except for wear/tear parts I have listed.
I cannot speak for the others who have had a bad experience with him and posted here. But by reading, everytime it sounds to me that their expectations were not realistic. Secondly, most of the people were really not into wrenching or they bought the bikes as their first bike .... not good on both counts, you don't buy 250cc or 400cc I-4 20 year old bike if you fall into one of the two categories.
Don't bother with his website, he doesn't keep it updated at all. Head over to his kijiji "store". Once he gets new bikes for sale, you can check it here

Good luck.
