My HERR motor is badass. I ordered one from Kevin last fall and just had the opportunity to begin the break in last weekend. All I can say is holy Christ. This thing breathes so deep you can hear it drawing air over the tune of the pipes.
340 mains, stock pilot, +4 timing, boysen reeds, no airbox lid, fmf fattys. Still a little hard to start, but once it is warm it kicks right over.
Kevin basically took a 1995 Banshee "boat anchor" and transformed it into an aggressive trail ported 4 mil monster.
I am going to do the final breaking runs at higher rpm's this weekend.
Worth every penny. I can't wait to race my buddy on his new KTM 525xc.
