Just put on a set of Avon Super Venoms. Given the great difference in tread and tire design between the original K-70 Dunlops and Super Venoms, do the original factory inflation recommendations still hold true for the Avons? If not, does anyone have any recommendations. Thanks.

I have found that the more modern tires require a bit more air than the old stuff. I generally arrive at a figure through experimentation. On my Rocket 3 I run 30 lbs front and 32 rear, on the 66 A65 I run 28 and 30. The higher pressures have also alowed me to eliminate the rim locks on the rears. The old K70 type pressures in AM18's will make them run quite hot, warm tires = good, hot tires = bad. Don 71 A75 66 (mostly) A65 72 B50MX ??441 highly modified dirt basher
Good tyres. A 100/90-19 will go on the front of '68 and later bikes but will slow the steering a little compared to the 90/90-19, you get a little more ground clearance though and Hagon makes 15mm longer shocks to sharpen steering a little and further improve ground clearance.
A 110/90-18 is about the largest you will practically get on the rear without clearance problems.
I am using a 100 width AM18 at the front and 110 AM21 at the rear, dunno if I would use a super venom at the rear, compound may be a little soft and there is certainly nothing wrong with the '21 if allowed to warm before getting aggressive.
