Hi Ujeni,
first, I didnīt mean my previous comment any badly. As I said, your restoration is very high level.
About engine, I just mean, that engine is incorrect for this frame number, because originally on the bill of sale would be this frame with any other engine. And this is very important for collectors. Same with Yamiya parts. NO trully collector and bike lover will pay so much money for replica parts. Yamia parts are very high level, but still not original one. At this moment I donīt mean original part which should be in original colour (it is ofcourse the best way), but original part, even painted, or refinished. Every replica and not matching engine-frame numbers will put the value down, because the bike is missing original story. Also your frame was modified little bit I think, which is also very important for collectors. I have some friends and they have some friends collecting exiting bikes and are prepared to pay high price, but bike should have original parts, not replica.
This was just only my explanation, why Iīm not surprised the bike didnīt sell for higher price, even it was restored very well with all your love you put in it.
Also with the tire. My recommend is to be very exact in the describtion, because this F11 tire could make some buyer wondering you are telling true or not.
regards,
John
