    more torque?

    This one's for the guys who have experience building V60's. I'm hoping Micah will chime in here. The question is, would it be possible to get a Futura to make torque numbers in the 80's? If so, what would it take? Big bore, big valve heads? Sure would be fun.....

    1060cc, stock ported heads, cam timing 102/105, stock throttle bodies, stock intake stacks, H-Pipe or equivalent to replace breadbox underneath and some time mapping on dyno. I was able to get 74 ft/lbs on my last Tuono with similar mods on stock 97mm pistons.

    Thanks guys! If I could only have one bike it would be a super Futura. This thing does everything well. With more power it would be even better!

    So...if power is what makes you smile combined with a Futura, I might suggest a bit different route. 1060cc pistons, squish at .9-1.0mm, cams 106/109, Gen2 late model big valve heads, gen2 57mm throttle bodies, RSVR intake stacks in stock RST airbox (easy mod) with 440cc injectors.

    A turbocharged RST is another option but, trust me this rabbit hole has a very deep bottom. I'd use an Aerocharger VNT type turbine, no more than 8-10 psi boost, single throttle body with common plain manifold and air to water charge cooler. If you feel a reduction in compression ratio is required use stock Capo Piston, provided you do not go crazy with the boost and detonate it...saves a a grand on your build. Fueling can be managed by PCV type power commander with manifold pressure reference added for blended alpha/n tuning. I rode an FJR1300 set up this way...HUGE smiles!

    I really like the naturally aspirated route. Is there still a source for H pipes?

    Not that I know of. Saw one go for $500 the other day on eBay...holy shit. I still have my original prototype...just in case I ever need it for myself

    So if you did go with a single throttle body, what size would be equivalent flow compared to our 57's?
    If you wanted a really really deep rabbit hole, would you go larger valves on both in/out sides and would you go billet cams with longer duration?

    51-57mm is plenty big for 200 bhp if turbocharging a V990. Pre or post turbocharger compressor. For best response and tuning it seems to me the way to go. Simplification when adding complexity is good too.
