ATV engine swap

admin

Bought a used honda 400ex for $5500 when I was 13. From age 13-17 I put $10,000 into race parts. When I was 17 I ripped out the air cooled single cam honda engine out and made new engine mounts for a dual cam liquid cooled yamaha yz426 dirt bike race engine doubling the HP and torq over the honda engine while the new engine was also 30lbs lighter.

Reply:I noticed the Nacs Racing decal....Is that Nac's racing in Saugerties, NY?  They still around?  I grew up in that area and haven't been back in a while.  Back in the mid/late '80's, The Church-field in Glasco was a great place to drag.  If I remember, Darren (Nacaratto) had a 250R back then.AutoArc 120 MIGMontgomery Ward AC/DC 230r.i.p. - Miller Thunderbolt 05 Jeep Liberty Renegade
