A customer bought me the engine out of his bike and old GSX1100 fearing that because it was burning oil the end was nigh for his bike, So I had to call him today to give him good and bad news... Good news the burning oil is only valve stem oil seals and because I've got the motor apart already for investigation work its not gonna take a lot to fix.
The bad news .... He doesn't actually own a GSX1100, what hes actually got it a stonking great race tuned 1270cc Wiseco engine. When I told him he said "I always thought the bike was a bit quick, but had no idea!"
I wondered why the head gasket wouldn't fit!
