FIRE sale gotta move this , need money for other parts so its going CHEAP
Got this complete Duncan Racing 340 Big bore Power Valve engine. I did not buy it new , It came in a 89 250R I picked up from someone I have known a long time . He said it has approx 3-4 tanks run through it .
I have the slip for the top end that is $2600 alone

Cases were blasted and all bearings replaced , there was very small hairline crack on bottom motor mount that was fixed and the case saver mts were welded so they could never break off

Duncan 340 PV top end 19cc dome
Duncan Pyrimid Reed valve
Duncan 39mm PWK carb
Duncan race pipe with Fatboy silencer
Hinson clutch

clutch and stator cover are chromed but is peeling
Really a stought engine Loren says 58-60 hp
I will sell it complete turn key for $2000 plus shipping
Full electrical, kicker, shifter, case saver etc etc

Or bare engine no accesories for $1600 plus shipping
This is super cheap for an engine of this caliber
I got it on ebay for more $ but wanted to offer it up to my 250R buds

Would this be a good xc, trails motor or more of a dune/drag motor?
Thanks, Sam
