the 4dl belgarda tzr 125 shares the same deltabox frame as some of the 250 tzrs and the szr660 so yess i believe you can fit a 250tzr engine fairly easy into one. however finding a tzr 250cc engine would be hard to as they are getting more rare by the day . and the 250 fetches more money than the 125 .
Under the seat there is the tank for the oil, with a cap on saying Motor Oil
200litres
There is no TZR 125 being in production now, but if it was a 2 stroke I calculated it would go an easy 145-50Km/h. If it was a 4 stroke it would get up to about 130 and 110 cruising speed. If you mean the old TZR 125 then that bike got 110 4 strokes and 140 2 strokes top end.

TZR's are available for purchase from motorcycle retail stores. It is important that the store includes Yamaha motorized vehicles, otherwise one cannot find a TZR at that establishment.
You can usually contact the manufacturer and receive a diagram. You can also call auto places in your town like Advanced or NAPA.
No but a 150 should, and you cannot stick a 250 engine in the 125 frame without major welding etc sorry, i tried this too :)
your compression should be around 125-135 psi. for a 250cc polaris trailboss or trailblazer.
No because the cylinder is twice the size of the old one if u put a 250 head on. Then the bolts wouldn't line up and it u had 250cc 2 stroke power on the 125 trannie you would be screwed
Yes any motor over about 250cc can be turbocharged.
