Took out my '80 SS440 this afternoon (-15C) and found that it was top end limited. It topped out at 60 mph (6000 rpm). It felt normal out of the hole with good mid-range until about 50 mph. It's odd...I hit an easy 75 mph last year...until the bumps get real scarry.
The primary clutch (Comet 108C) has been rebuilt since last winter so I'm pretty sure it's free to fully compress. I'm running an el'cheapo Kimpex belt but it doesn't seem to slip. The secondary clutch spring angle set at 120º degrees.
At 60 mph, there is some amount of dead range (last 1/4) in the throttle that doesn't get any response from the engine.
Any thoughts?

clean out the main jet
It hasn't been done it a couple of years. Is there an easy way instead of the obvious take-everything-apart (3 cables) to get the carb & main jet out?
...it'll be -20C in the garage this week...
Thx

loosen the screw and turn it over you don't have to disconnect any of the cables...
....so I braved the cold and got the carb out.
Both intake vents (facing the airbox) were crudded up. Ran cleaner through everything etc. The main jet was clean but it may have been starved if that 'vent' was restricting incoming air too much.
Gotta get it out there again.
