Absolute Cheapest 66cc and 49cc Engines I Could Find!

Is the mid range power good? lol I swear my engine runs better than my other ported eBay kit :|

Is it the catalytic converter? Idk about those I do remember reading something about someone said they wouldn't use it though... IIRC!

 

[Frankfort MB's]

I'm using the same exhaust lol

 

[FurryOnTheInside]

Damn. I hope it turns out to be a simple thing and fixable.

 

[Hello Moto!]

I'd have to say that mid range is where it performs best. I'm not sure what the deal is.

Have you ported before? If low end power is what you want lower the exhaust port

 

[Hello Moto!]

I have never done that before. I wouldn't know where to begin lol

Do you have a Dremel tool or dental drill? If not how about a air compressor? I use a die grinder with a carbide bit and it works pretty good (nothing that a peice of good sandpaper can't fix)

 

[Hello Moto!]

Do you guys know how big of a rear sprocket I could go to get good low end. How big is too big? I mean I don't want to drive around 15mph top speed lol.

I'm just thinking of trying a bigger sprocket. I don't really wanna tear the motor apart and attempt to modify it.
