Yah. Have some video footage someplace that shows a 650 triple polaris and 650 wildcat leave the line ice draggin with ski's in the air. Then, in the foreground, a lone 77 SRX 440 comes sceaming past both of them!!! Got a 93 V4, love it, but always maintained that one of the old X's can show a roosters backside to any of the new heavies!
I have just obtained a rough 78 SRX that I would love to turn into an ice racer, sad though, probably much like your 340. I found new hoods on the net, both the production hood and the 75 GPX water cooled hoods. But my problem is the bellypan. Anyone know of anybody making these, or if, (forgive my naive optimism) Yamaha miracously still sells them?!
