Did you ever get it running properly before you mess with it any further?

You seem to have plenty of cash to spend on a 50cc bike tuning the engine, and you seem to want every bit of bhp and speed that spending money can achieve with your machine. If you really do have £££'s+ to spend on it and want a very powerful 15bhp+ engine, then you should talk to some serious race tuners specialising in these bikes. Most people on BCF will not know much about chasing maximum power from a 70/80cc kitted 50, and most will not want to know or even condone doing so.

You realise that a powerful engine with £££'s spent on kits, crank, carbs, ignition, and exhaust mods is going to be pretty stressed, peaky, and require alot of intensive maintainence and re-builds probably every 2-3000miles. Is all that worth the expense that getting you that kind of performance will require.

A restricted 125 will keep up with many lightly tuned 50-70cc bikes, and a 2stroke 125 that has been de-restricted will be much more reliable and blow your trick 80cc bike away with not a penny spent on it!
