Working 4 stroke 9cc replica of a Harley Davidson Panhead engine. Bought this to build a working model of a Morgan 3 wheeler but not going to get around it. Comes with the optional Stirlingkit.com aluminium base, kickstart kit, fuel tank, cdi unit, ignition lights and switch. Lots of information on the Internet. These are beautifully engineering working replica engines. Run on Zippo lighter fuel with 2 stroke oil. Rear exhaust needs to be remade to clear the fuel tank, one of the fuel tank upstands needs a fettle on the mounting hole . All in immaculate condition. You won't be disappointed, very impressive bit of kit. Heavy! Will be carefully packaged. Anything else you want to know please let me know. Thanks.
