You need a good port and polish on the head, the stock carb rejeted, good quality cdi and coil, and the exhaust opened up to allow better breathing as well as a UNI or K&N air filter. I personally havn't had much luck from the cdi advertised. The 30mm carb will be too much carb for your engine, unless you were to go with a 62mm big bore with at least a 3mm stroker crank shaft. CKAU is correct, the engine is nothing but a pump. With too large carb the engine will not have the volume to operate a 30mm carb efficiently. The stock carb will work very well up to a 180cc. Going bigger is not always better everything has to match for peak efficiency. I have made the mistake of running too big carburetor, but have found that the engine will produce more power with less jetting using the stock carburetor. Now I am not saying that you will not notice a difference with that setup but you will not get all the performance the engine can produce. You have to be careful since there are many salesmen out there selling their product, but very few have done any research to see what works to produce the most power.
