06-25-2014, 03:18 AMI didn't change chains , I drive a different model , with diff chain
and I think y the higher attainable speed , is simply because no one else has DARED/or botherd to gear for 90, and accepted just the 35 tooth rear as max , which is 60ish with motor screaming , like wants to explode (might varv wih your larger tire)
u need a additional 10-20% (front sprocket) depending on lbs. , im 165

06-25-2014, 03:30 AMeven barnones 45 to 30 swap (right?) was/is only a 30% boost to stock
mine has been faster than 60 , since 8 days after it arrived and I maxed front sprocket
yes up an incline or stiff headwind and nothing to draft 60 still my max ,,, in 4TH gear
IMO , you cannot possibly attain that which u have already givin up be4 u started , by gearing so low
if you've geared for 75 even down hill you will never pass that speed as valve float will actually engine brake u preventing more speed EVER from being attainable
gearing really high has drawback being really hard on valve train

Barnone used a 2.30769231 ratio and I believe went back to 2.69 for the same lack of power reason I just posted.
Dan, I'm going to give you the benefit of the doubt on both the higher ratio and smaller chain...
But do u realize you are claiming such a massive amount of better performance than absolutely everyone else gets that it is just hard to believe.
Really I'm not looking into getting into a pissing match about this but that GARDO creep spread allot of bull shit about this bike that helped influance me to buy it. I may not have otherwise...
and I just think the true potential should be clear, not subliminal wishes...

06-25-2014, 03:53 AMI agree axa a fat man buying this isn't gunna race the highways at 70 , I am 165 and its not usual to get perfect circumstances , but 60 attainable and sustainable , with bursts +15 depending on heavy driver and conditions
same carb , engine , tranny , electronics , brakes = neck angle , diff chain and sprockets the only real diff
