Getting rid of my spare motors to make some room, heres what I can tell you about this one
It is a stroker (not a 87-89 long rod a real stroker) I am pretty sure it is 1.5mm to 2.0mm stroke over the 87-89 long rod.
The crank is custom built and ballanced
has a happy face and the # 5782 and then 250r engraved in the lobes (it is almost new condition).
The cylinder is a stock 1989 jug sleeved to 72.45 mm bore then support braces where welded to it to allow for more porting and has a full MX port.
The sleeve extends out of the cylinder in to the head about 2.0mm that is where it take the extra stroke it also runs a standard spacer plate on the bottom, Has a matching LRD cool head uses O rings for head gasket on the cylinder side and LRD port #s 22770602 on the inside of the intake, it has PSI 4216 stamped on the underside of the cylinder. the cases are good and have been trenched to accomidate the stroker crank.
the exhaust flange has a choke in it classic arlan from LRD and it has 19mm reed spacer (thats twice as thick as a normal one)
I have pics of the engine appart to show condition it has new bearings gaskets and seals as well as a new clutch.
all other engine components are low hour from a 1987 gears shafts ect.
ballancer is a fresh rebuilt unit
I would like to get $1000 plus shipping
I put in some pics
