Hello from Estonia

[Extinction]

Hi, I'm Kristjan, I live in Estonia and I'm currently building a bike with Yamaha DT125R chassis and Qingqi QM200GY engine. It will be used on both motocross and enduro tracks in future...
Everything started when a friend went for a ride with my Yamaha and seized the engine. He had the QM200 in his KX125 frame before, because the original Qingqi chassis wasnt very good, the rear wheel broke apart and ruined everything.

Iv'e previously had some Riga mopeds, three 350cc IZH Planetas, Motorhispania Furia with full MK Pro Race 70 engine, 2 Yamaha TZR125R italian models, a Honda MTX80 which was always broken, Aprilia AF1 125 Futura, Gilera MX-1 125 (I regret selling it, could have been a nice project bike), Suzuki AY-50 Katana scooter, three Kawasaki AR125-s (I love those, really cool bikes if u ask me), Yamaha YZ80, some kind of Qingqi 50cc moped...

Besides the Yamaha DT I also have a Honda Dio scooter.

I found this forum when I was searching Google, trying to find out if anyone has made his QM200GY go faster and what was done to make it happen. :D So, any advice is welcome! :) I'm more familiar to two strokes than fours.
