I also have the Polini 23/64 gearbox.
And Jack, I only made the mods recommended by Malossi. The transfer gap was machined 20mm wider, what this is in degrees, I don't know.
And I must say, when we go up a mountain pass and I am in 3rd, no 200 can keep up with me. (Or even when we are on level roads.) I just came back from a ride, and I measured my speed with my GPS: 110km/h on a level road.
So speed and revs I have enough, I just need some more torque when going uphill.
I think your geared higher than a factory P200, meaning more over drive or less rpm at a given speed. From my experience, I bet if you are on a small hill you slow down, driving into a strong wind you slow down, a windy day on a flat road you slow down, on calm day on a flat road you are fine. I tried a 23/68 on my 177 and it was to much and I went back down to a 22/68.
My Pinasco P225 with a 36 tooth 4th gear and 24/65 clutch gear goes 105.51 kph at 6000 rpm.
Your 166 motor with a 35 tooth 4th gear and 23/64 clutch gears goes 105.28 kph.
If you have a 36 tooth you can go 102.85 kph.
My point being you have a Malossi 166 geared the same as my Pinasco P225. I bet you are having a hard time with any hill. You are also geared higher than my previous reed valve 177 motor that didn't like a 23 tooth cog. If it were mine I would try 21 or 22 tooth, clutch cog. I was told not to gear it any higher and I had to try and I ended up with a gutless scooter that couldn't climb a hill with any speed. I did like it better around town.
