Now is the time to convince me a 4 stroke is better then a 2 stroke for my next build. Not a thread about which is better, more what are the advantages of the 4. I have never used the 4 stroke but have built a few 2. What do you guys think? The build will be on the Grubee GT2 bicycle, Ill average a 10 mile (round trip) commute 4 days a week, 30mile commute one day a week. Combo of early morning, day, and late evening driving. Mostly flat roads, southern cali.
