Should I get a biturbo and clinder kit? It's cheap, And my engine still makes the noise. It doesn't seem to be hurting anything, given that it's unchanged after over 200 miles. I will get the biturbo probaby and only get the cylinder if I blow somethingg. Also, mine is a 2hp. If I order a standard maxi clyinder, will it be 1.5? Or is it the cylinder head and carb that delivers the horsepower. Any feed abck ould be appreciated. I still wish that buzzing noise ould go away. Maybe with the biturbo the exhaust noise will mask it :)
