im 17 and going to school with a crf250x no time for a part time job... but in a couple weeks i get my tax deductions back.. about $230.. about 80$ of that is goin to buy fluids, chain wax, etc..... i have a stock bike, whats the best investment i can make to get the most power? i was thinking the emissions control/throttle stop((cuz thats a pain in the ass when it bogs or stalls on you in air when you need the power)), but i really have no idea where to start. once summer comes back around, im getting a full time job and putting every last dime into my bike.. what should i start with then, when i have more money??.. i was thinking the pro circuit ti4 full pipe system and new valves... but any suggestions would be highly appreciated. thanks!
