[400exredrider]

well i just bought another 400ex...the other one is bored out....what do you guys think i should do get a IMS440kit or another Curtis sparks 465? and with that put a web cam in? or should i port and polish? which will keep it reliable and give most power?...the 465 is holding up good sofar.....:D well i was just wonderin it is a nother 2000 red of course...let me know what you guys think?....thanks for lookin:blah

the 465 is gonna cost alot and more extensive work and less reliable where as for 1,000 u can do ur carb, 440 kit,head port and polish,cam ,filter and a few other things
