Sir, i have a question? I have yamaha Ray Zr 113cc, i would like to change 125cc. How can i have this 225cc big bore kit, and is it pissible i will fix it??
Robert Meutsch An easy option would be to go 155cc with a high compression piston this should get you about 65-70mph alot better acceleration and climbing uphill for a kit you would be looking at about £100
I have an air-cooled Fly 125cc. It is pretty quick as it is, but am considering an upgrade. Does the kit just pretty much bolt right on, and you're away? Or do you need to up-jet etc? Cheers
I know you wasnt asking me but heres an answer. Yes youll need to upjet or buy a bigger carb. The reason is because your increasing the volume of the cylinder so youll need more air/fuel mixture to get the most from the new mod. Hope this helps cheers
If you look at modern Moto gp riders and they all got a soft spot for scooters as they all used them , you goto read rossi book as some funny stuff he get upto on them , I think the UK was late to cotton on to Europeans riding them especially Italians and Spanish youth where years ahead. We where more dirt or road bike then scooters.i think most youth in UK now use scooters where as the norm goto bike was plastic c series honda, still a favoured bike as it learned so many right around the world ,sadly in decline cause the scooters cheapness and easier availability
