Well it runs s rides 10 mph up hill .20 moh on flat but god its gutless 11t front 48t rear
Change gearing or bigger engine as shes only 27cc

How long did that 6 tooth sprocket take to make?
What rpm's does that motor top out at?
Gutless is 11 to 48 teeth on 26" wheels which is 106 mph at 6000 rpm
a 6 tooth changes this to 58 mph

6 to 88 teeth on 26" wheels is 31 mph at 6000 rpm

Thanks for the reply .the bikes on 700 wheels currently 6 t to 48 t rear
sprocket took 2 hours to make with hand tools and a drill
My next option is a Jack shaft bottom bracket so 6t to 48t to 6t back to a 48t or invest in a 54t or 60t
But I'm currently looking for a bigger cc chainsaw motor as an option

Then you need a Husqvarna 61 or 272. The 272 is actually 70.2 cc.

I'm changing base bike to retro fit the engine as a friend needs a large framed bike for work engine in middle jack shaft and better gearing
