Big R., I know it. 
Im okay with it though - just gonna build an ejoyable little scoot. Im scheming on a certain cafe inspired modern bike, so Ill worry about going 100+ on that thing and not the little guy.

You;ll need a pushstart (ill tow you to speed), and 100mph shall be yours.
i got another idea: i'll get some stable tires (2.75 and 3.00 isn't confidence inspiring) and you can just tow me up to the ton
man screw the ton... on my enfield when i am doing 80 that sucker is SCREAMING for mercy, yet you put me on some fast twisties, i can rock those suckers in knee dragging turns like no other... anyone can make a bike go fast strait, to me, a cafe is a cafe for its handling not just doing the ton. I took an off ramp at 80mph last weekend with a few buddies on thier rockets and their jaws nearly hit the floor when we got off the HWY. they said i was almost draggin my knee and could not belive i could turn like that on my cafe (TX500) I told them that is how i built the bike, rebuilt the front forks with blended oil (10w/15w) fork brace, lowered it jsut a bit, tucked the pipes in tight, progressive rear shocks, good tires, ram air and oil cooler so i can keep it in that low gear with high RPM's and power though turns...
and it is true... the bike will never be a screamer in the strait aways... the trick is to make it so that they have to play catch up in the twisties with you... pick your battles and prepare wisely for them. I learned this lesson on my first cafe XJ750... my buddy had an apprillia 50r race scooter... he SPANKED ME in college on this twisty ass road... after that, i fell in love with turning!

Split personality, I fake being smart
Unless you have a LOT of power, wider tyres will only slow you down.
There is nothing wrong with 2.75/3.00 combination.
It should be pretty simple to 'Do the Ton' although acceleration will only be something to dream of.
If you had a twostroke (RD125, RG125, never did the Honda or Kawasaki)) it would be too easy as you could just port it close to MX spec, they were good for about 120mph on a slight downgrade.
The XL125 Honda would do a genuine 75mph (almost 90 downhill) with 'dual sport' tyres and wide bars after I 'modified' it a bit

regarding the wider tyre thing, i meant if i was going to get towed up to 100mph, i'd want them for the stability. wouldn't consider them for any other reason
i'll need to pick your brain about that sooner or later pj, i've got 1 working cb125 motor, 1 almost complete cb125 motor, and a possibly seized xl125 i picked up for the 6-speed transmission...
i've gone so far as to pick up a 63mm piston and a liner to suit, though i need to have some machining done to get them into the motor. i've come across a chinese copy crank with (i think) a 59mm stroke (versus 49.5) that needs it's spindle shortened to fit (due to electric start i'm guessing). might do that, or might work out an offset crank pin to hopefully get another 3mm stroke or so.
it's funny how with small motors, every millimetre represents a large percentage volume gain. heh :/
getting odd parts in australia is a bitch, finding complete motors to scavenge for a respectable price is a whore, and having machining done is disproportionately expensive to the work done.
i'm a tightarse, and i like doing things myself, so handing money over knowing what's involved doesn't rest well.
sorry for the hijack!
