Hello, I have a 2012 kx250f that I race supermoto on I currently have a pc5 tuned for 92 and u4.4 on a switch also a yoshi slip on. On u4 I only got 35hp and its getting fuel into the oil so I'm looking to refresh the top end.
I'm looking at buying a weisco pro lite piston and stage 2 hot cams to get alittle more out of it.
Open to suggestions!
