Hello. My name is Martins, 31 years old from Latvia. Decaded to share my scoot with you. This is a yamaha BWS 1991y, bought it last year in the middle of June.
1st day photo. It had malossi sport 70cc cylinder, malossi rhq crankshaft, stage6 pro replica exhaust, 19mm china carb, malossi e13 air filter and malossi multivar variator, stage6 mk2 clutch. Everything else in the engine was stock. First drive and I was very surprised that for 70cc it was so slow, it maxed out at 55km/h at wot, but acceleration was not so bad.
After that, i put on front fork from yamaha aerox and wheels from sr50 2gen aprilia for better looks "my opinion" =] + converted drum to disc brakes. Wanted it a little bit faster so for a good deal I got mxs racing 70cc cylinder. After that it was different story, perfect power for daily driving and riding on rear wheel
Max speed with draggy was 90km/h and 1/8 it could do in 11.25sec not bad.
After that i drove all season and enyoyomg it. Then winter came and I decided to upgrade the engine more. So I found for a good deal minarelli horizontal engine cases + 2fast crank + 2fast 100cc cylinder for a good deal and could not miss that. After that bought r/t 100cc exhaust, r/t inner rotor ignition, PWK 34mm carb, malossi LA furia overrange set and put all that together. I dont have a lot of pics on that process because i was documenting all that progress in my youtube channel so it is wat it is.
custom intake manifold
1st test, without overrange transmision.
More vids, racing i3
Testing grip to race 650cc bike
Race
And some POV driving , still stock gearing, need upgrade to longer ones.

so i decaided to not take part of the race. But end of the drag i went to race guy who was taken 1st place to see if i could beat him and then clutch did not slip, but i used 70% throttle on launch.
