Looking at the pics from lidest I think this could be done on the cheap..
He seems to be running a 180-190mm disk with the stock grimeca caliper and a simple adapter plate. The stock caliper is good I think just needs more leverage (bigger disk)
I'm going to order a 180mm disk when I can and see what can be done but my car needs a pile of stuff (at repair shop now) so scooter funds are toast both for modding or a second 4t scoot.
Did get my jetting better though. Lowered the needle a notch and went down to a 98 main. Much better throttle response and extra 500rpm max but sounds lean off throttle again not sure this can be cured.
Also looking for a softer contra spring. The red one is too stiff to shift up all the way so I might try a yellow one. The scooter budget can handle a contra spring I think.
Here's some interesting pictures...
My old front brake pads
So that explained the lack of front braking power. The stock caliper is a 2 piston and takes big 40mm wide pads. It's adequate with the new pads but could use more leverage.
Here's the "TurboMax" variator it had when I bought it.
It's an interesting design but I didn't care for it. You can see the bushings get worn in the middle the same as regular rollers flat spot. There seem to be no teeth in the backing plate...not sure how that's supposed to work.
This is a shock riser that I bought but doesn't really fit the short case. I'd sell it for $20 plus shipping. Same as I paid for it.
I also switched from ProHonda 2t (cheap stuff) to Amsoil HP synthetic. I like the big neck on the bottle...think I could carry an extra 2 or 3 quarts of gas under the seat in Amsoil bottles.
