Nice Nitro! I remember the earlier (71 or 72) 440's....fast!
Vintage sleds are fun to work on and ride. They still turn heads on the trail and neighborhood rides. It's great seeing the resurgence of the older sleds especially among the younger set that seemingly have little idea of where the sport came from
I've owned:
67 Larsen Falcon (?)
72 Suzuki Nomad 360
74 Yamaha GPX433 (silly fast F/A)
And now own:
'86 Yamaha Enticer 340 (anybody got a hood??)
94 A/C Puma 340
Going to own:
early Polaris XCR 700 (ok, not so vintage)
