Would have expected a spare powerband amongst those quality spares.

She is a one of a kind, hold onto her for another 5 years and she will be worth 10K

Wow! Stop squabbling you lot, I think finders keepers in this case unless he wants to give dibs to the next in line.

The highlight for me is the shot of the bike easily jumping over that flatbed without even needing a human on board! Must be the bike equivalent of Herbie.

was gonna say "the fins must've fallen off if bored to 250" [forgetting it's water cooled ha]. Special thinner water makes them go faster too?--must get some.

Iain,
Just sent him a long winded reply and gave it to the tosser, to correct every bit of his advertisement. Imbecile, shits me when sellers bullshit about an item.
Waiting for his reply? Won't hold my breath.

I always like it when they answer that I know nothing about their bike and how would I know that what they have done is impossible , eg one seller in the US was selling pistons for DT and RT Yamahas when I asked how the same piston fitted both a 250 and a 360 I was told to mind my own business  . just plain stupid I guess , but some newby will fall for this garbage and get burned .

Dacca rode it after it was bored out.

He was just too fast for the 125 class :)

Just think of this for a minute though. Back to basics lads!
if it has a 2.0mm oversize piston in it, could that not mean in someones calculations...
125cc's x 2.0 = 250cc's

put a 2.0 mm o/s in and you can drop it straight into a 1000 cc roady and kill them on power to weight ;D :D

I just did some quick calculations it only needed to be bored out to about 80mm thats 24mm os no wonder it goes so well.

its bored out so much the piston is now air cooled "flapping in the breeze due to no cylinder left"

You Honda boys just can't grasp BRUTAL Yamaha power. All Yammy 125's are waaaaaaay more powerful than the competitions 250's. face the facts and move on ;D

That air cooled piston thing got me thinking about the low friction environment due to minimizing cylinder wall contact that this visionary has perfected, or could this be some secret works bike exposed ?

my 'briggs' lawn mower motor has an 'alloy bore' [so i discovered]. OH GOD!! maybe he's having the last laugh 'on us' & just kept boring it till it fitted. Damn. Probably used one of them yamy 250 pistons on ebay that suits 'both' yz250 & 360--maybe not.

I still reckon the classic part is the wind deflector on the front guard. It was either running way too cold or it is an attempt to keep the front wheel down.
