Yeah, I haven't been this jazzed up about a bike in a long time! Glad I spotted the deal & nobody bid on it.
Sometimes the torque loss isn't worth the sound. Torque is great on the street. You might have been able to get it back with a custom map for the EFI. My buddy had one done on his insane GSXR1000 that we built. They tune 10 throttle positions in each gear, plus every 200 rpm in each position in each gear ...... it's pretty involved -- takes about 45 minutes. At the end of the run, my buddies brand new rear tire looked like it did 100 race laps without taking 1 turn!
Shredded in the center with purple on each side, & about 4 inches of brand new rubber to the edge.
180+ rear-wheel horsepower will do that...
Torque is one of the reasons I've been hesitant on tossing my stock RD pipes in the loft -- I love the broad powerband. But I also love how responsive 2-strokes are to pipe changes.... & the sound is FANTASIC! Got some decisions to make.....
I just put an FMF pipe on an old YZ80 I have kicking around. It went from having broad, but unimpressive power, to EXPLOSIVE, LIGHT-SWITCH WHEELIE IN ALL 6 powerband!!
It has ABSOLUTELY ZERO low- end power, but bring the revvs up & OMFingG!!!
I could sit in front of the front axle & it would still put me on my back in the first 3!
