We had a day on the dyno and did a few miles on 3 GT200's my GT230 and a GT186 yesterday.
Im sure my helmet camera doesn't like the kit because every time I use the camera while on that scooter I have camera problems lol. the problem yesterday was an electrical power problem with the battery. I did get some footage on the way to the dyno though.

the yellow GP is Miks bridge port GT200 with no mods, the camera scooter is my GT230 and the LI with us is a GT186. Miks had just had new bearings , drive side and mag side along with a new crank and had done no miles before this footage so he was running the bearings in.

Not going mad but gives an idea of how they run.

You will have to wait for the article in scootering for the dyno results and Sticky's view on the kits. should be interesting.



this is the speed graph, the part in the video is from time line 8:37 to 8:51

they looked rapid,for only a 200 the yellow gp shot off and left you standing,the 186 was keeping up to some point,
they do look a good kit,are you going to try it at the 240/240cc.
what sort of speeds were you doing as I couldn't read the speedo this time

look at the huge speed graph I posted under the video for speeds! the graph is GPS speed not imaginary lambretta speedo speeds

The yellow gp shot off in 3rd, I was in 4th to show how the kit pulls in top.

ok im blind as a bat lol,it looks happy enough to sit at 60 to 70 no probs and still plenty of poke left,i know its not at full chatter yet or the yellow one.
how do you rate the kit against ts1 225/230 or is it really early days

[eden]

You will have to wait for scooting to come out as I wont be posting any graphs till after then!

But yes imo the GT200 is better than a ts225/230 by some way, out of the box its better than many road tuned TS225/230's.

but then it depends on what you think is good.

For now I wont be saying anymore.

What's the graph for the speed mate , is it an App for phone?

[slangen]

Eden, could you please share what gearing and exhaust Miks yellow bridge port GP/GT200 is using?

Im sure you mentioned your setup somewhere too but please share.

Very tempted to get a kit but I am running out of engine cases to put it in...
