Ok...make that 82-83mph (just checked my gearbox/rpm charts).
But if feels like 90 as I blow by all those stock cb350's.
Good advice in turn one...strangely enough I've found myself edging toward that very thing... last race I noticed I had put a finger on the brake coming into 1 and was back on the gas by the apex. I tend to take a highish, deep entry into 1 and try to straight line it to 1a...sorta...I've found I have a hard time getting around the 1a rumble strip if I take a low tight line..bike kinda pushes the front over to the right just as I need to be going left a bit for 1a. In other words I like to get a good start turning on the tail end of the straight cause if I don't, I lose too much speed having to wrestle it around 1a.
I think all production racers will be four stroke within five years. I'm guessing most of your experience with four strokes on track has been with vintage bikes? Modern water cooled four strokes are very forgiving of jetting, much less prone to detonation caused by hot-spots...mainly due to flat top pistons. Dual overhead cams allows very small valve angles and short, small combustion chamber, so the pistons don't have to be domed to make compression. So they end up with good even gas flow, no protruding edges on the pistons to get hot. Nice even flame propagation.
In short the four strokes will probably be considerably less trouble to tune, and less maintainence intensive. However...considerably more expensive to fix should they break. Another plus for the four strokes is you will probably see some fuel injection, all very programable, lots 'o' fun.
Don't think thumper, think kinda of a two stroke behaving four stroke, they will be high revving, kind of pipey, short stroke with little engine braking. In other words...the best of both worlds..except when you blow them up. Probably easier to ride as the powerband will be somewhat broader. Should be in the area of 40-42hp but with increased torque.
How does that brake work on the 350 Duc? Probably no real indication but following you a while in practice at Frontier I had no problem staying with you on the brakes...looked like I might have a bit more brake in fact. I've got a worked t-500 brake, what most people would call too much brake for a 175...call me a freak...but I don't believe you can have too much brake. I can do stoppies with it anyway
What's the Duc weigh?
Yeah...we gotta get you on a 175 so a group of us can follow you around the track. I'd be real curious what lines, etc you end up using.
