HAHAHA, Thats the most insane little thing i've ever seen.. I can imagine tricking my mates ahaha, saying its a 50cc then they get on rev it a little bit in first and flip the bike 10 times.
Ummmm guys in case u didnt notice it aint got no exhaust, where is the expansion chamber gunna fit?. If you did get it started I bet I could hear it from here 2000kms away.
OMG!!!!! the only bad thing about this bike..... is the TS400 engine parts are a very dying breed & are basicly not available anymore unless you find some old Genuine suzuki dealer that has old stock around but them you would be looking at a price of like 15 to 20 times more than the bike...
the best way would be to convert the rod & piston to something more modern when she blows up..
