[gresh]

what is the best engine work to do 2 a 300ex out of fourstroketech.com and powroll.com

[2k2-300exnj]

powroll has a 352 kit and u can buy i bigger carb from them prejetted to fit it

fst has a 390 kit for the 300 for their baiggest baddest motor upgrade but that isnt for everyone


i personally when i get my front end and a new swingarm that is a little longer for the better motor i am going to go with profab atvs 385 kit with everything a jag oil kooler, hardened rockers, titanium valve springs, all the goodies u get the point i would check them out to

u also cant forget engine builder such as hetrick, tc, sparks and all the others
