How do I make my 1993 honda 300ex catch up to a 400ex. Would I buy a new air filter better carb?? Also would a slip on muffler gain me more power?
Okay thank you, I think it would be cheaper to just get a 400ex or 450 lolso we want a 300ex to have 400ex power or more...ok so this is what we do.
5 angle valve job, ported intake and exhaust sports
high end exhaust that flows
larger diameter carb
fly cut cylinder .010 to .020 to raise compression
OEM piston with new rings (you use OEM due to them being very light and keeping rotating weight off the cranks)
We did this to my raptor 660 and took it up to 60hp, the cost $2100
should you do this to a 300ex yes only if you have a blown up machine you got for under $500. If you spend good money on a nice 300ex let it stock. Wont make sense to have a 4-5K 300ex unless you racing nationals.
don't believe me 32years of being into this sport.
I'm building one now since I parted 5 machines and got $3800 in my pocket and a free machine. If not I'd not build one. I'm old and need to ride slow with my daughter.
