Sorry guys, new to this site.
About 3 month back I decided to buy a new bike, a Sinnis Blade 125, I do love the bike however I feel like that the 125 engine is a little bit weak and I was looking into a 'big bore kit' I went to a few bike shops and they told me to 'sell that piece of Chinese crap' and go back to riding pre-owned Honda's.
If someone can please help me or point me in the direction of what to do in this upgrade I'd be much appreciated. I have about £500-£600 to spend on this project and I'd like a reliable finished product.
If you wouldn't mind posting links for the parts I'd thank you a lot, I'm pretty new with riding these things on the road (Used to riding them in fields 'n stuff) so info on sprockets may be helpful too, thank you for your time.
