I just recently picked this bike up and it runs pretty good and all but once I get the power bug. What are good mods to do motor wise. Other than the long rod because if I want to race that would take me out of spec correct?...Is it a flat or a domed piston stock? If it is flat is there a domed one available for higher compression? Also some misc. questions..roughly how many hp does this bike have stock? I KNOW ill get flamed for this one but..I've been curious lately is there any numbers floating around the internet or that you have from personal experience the 0-60,1/8, or 1/4 mile of a 250. Thanks for your time. Later
