Stock carbs is Ok with 836, ported head, larger inlet valves, hotter cam (AF SS-1=. I'll finally put my Mikuni VM29 on again with new OEM inlet boots. Last year was 84.
Problem with Mikuni inlet boots made me to use stock with bigger main jets (140-145), needles one step up. Worked really fine.
My new CX7 cam will most likely prefer my old VM29's that look like new.
836, ported head + cam + 4-1 + KN type filters (pods) will make a difference. Carbs after these goodies is my experience.
