Hillclimber I am very interested in your project even if it does have too many wheels ,this year I rode a 280cc Honda two stroke in the 350cc class and despite having a double lung transplant august 10th 2014 and being diagnosed with lymphoma cancer this june have won the NHCA 350 championship .I would like to know what meetings you do and meet up .back in the 70`s Rudi Kurth & Dane Rowe used crescent or monark outboard engines in a roadracing outfit and Kim Newcombe used one in a solo bike might be worth a google . Don't think you will get oil lubrication problems but I am no expert . good luck and keep in touch please , I can be contacted easily on
