Here you are bidding on a 63 Reg Yamasaki YM50-2D ; Bike is in excelent condition and has only done 350 miles since the upgraded engine was put it. Engine has been upgraded from a 50cc to 155cc (Now 18BHP Super Fast). I still have the original 50cc motor which is included in this sale !The engine runs perfectly once started but the kick starter needs looking at ; for some reason the kick starter seems to be faulty because it needs some amount of pressure to kick start it ; the local garage told me that i just needed to get a new kick starter (Stainless Steel) a bigger size because the kick starter comes into contact with the footbrake ; or maybe it just needs the compression on the kick starter needs sorting. Also the wiring needs looking at because the mph dials work but the revs and the petrol level gauge doesn't show (the local garage couldn't sort the wiring because he didn't know how).  I purchased the bike for ??1200 and then spent ??460 on the z155 racing engine itself without including the costs to fit the engine and a brand new footbrake (just needs to be fitted). Here is the link of where i purchased the engine ;- http://www. ebay. co. uk/itm/Stomp-pit-bike-z155cc-WPB-Race-ENGINE-KIT-18-hp-Zongshen-Demon-X-/351082271254?pt=UK_Motorcycle_Parts_13&hash=item51be225216Reason for sale : passed my driving test and now looking to buy a car so need the funds.  Yamasaki are a long establish motorcycle manufacture. who sell bikes all over the world. as you may guess from the name they are a Japanese company but like most produce there bikes in China to keep the costs down.
