Killer Bee...or not..049 but 051...

I bought this new from the UK distributors ( Amerang at the time ) when i had a model shop in Liverpool , bought in 1999, in a black and red cox box marked Killer Bee 049

Has slit double exhaust ports , both are the same size, has 2 wide transfer ports that look cut in one go with no extra side boost ones,

Piston has one groove at the bottom, doesnt go into an 049 cylinder from any 049 but fits into a 1988 Teedee 051 perfectly, at TDC the engine has no SPI at all, piston groove is much deeper on the TD 051 than this engine

Piston is slightly shorter than the black widow 049s or the 051 teedee...still no SPI

Has standard type crankshaft, KB starter spring but a hex prop driver, yellow needle valve and High comp head and killer bee back plate with wide screen free venturi

So.....not a real Killer bee... just a load of assorted parts, not even a 049, its an 051....with single piston groove and no SPI
