Big motor? NOW you have my attention That lower end is nice with a TB 57mm jug & slug and a ported Lifan head, for a couple hundred bucks. Add a VM26 and you're almost doubling the horsepower. Tak decomp cam will let the electric leg work. 20 years of 500cc MX has my knees trashed, so I'm a big fan of thumbies.
Thanks for the suggestion, but I think I will stick with the hybrid motors 65.5mm bore.
