Like I said, the ped is my new toy, I got it specifically so that I can play with it and the 70cc kit. I've always wanted to get a ped or a scooter (ped prefferably).
Knowing that I was going to put the kit on and that it might ruin the engine ( you see I do pay attention to the posts here ), it seemed silly to go through the time
to break the original engine in, only to have to do the same with the upgrade.
Plus, I would rather break the whole thing in at once, rather than having the trans "used" to the smaller engine, and then adding the newer one.
After riding the ped for a little while, I decided that I really wanted to get more into this, and got out of my last project (anybody want to buy a 54 Chrysler). I can buy
a new motor for the Tomos for what some "parts" cost on the car.
The ped isn't going to see a whole lot of use either, mostly my wife using it to drive a couple of miles to and from work on nice days, and then whatever abuse I can squeeze in on the weekends. Now that she has gotten used to the bike though, I probably will be buying another soon, and just changing the carb and adding a biturbo.
I tried the 27 tooth before I put the kit in and it gave me about 4mph on the top end, letting me get comfortably to 35, but no faster. It's worth the 27 bucks and 15 minutes it took to put in place.
