I recently picked up an 82 4x4 p/u with the good old 22r. After replacing tons of stuff to get it to run decent I took it out for some wheeling on a muddy snow covered road and the truck did some bogging out and stalling when on a good pitch. What do you guys reccomend for a replacement that will still do half decent on the road? I bought this truck primarily to tow around my dirtbike and I am super stoked with its performance off road, bogging aside. But like I said it doesnt do so well at an angle, it also suck pretty bad driving the Teton mountain pass from Idaho to Wyoming. Is there anything else out there besides the weber or efi that I should know about including tricks to help the stocker do better? Also, will rebuilding the pistons help much if it has over 130k miles or should I consider another motor? I look foreward to your replies...sorry for the small novel. I am glad to be part of a group that has as much info as Thumpertalk for motorcycles. Thanks a bunch fellas! Oh ya, I almost forgot... will an aftermarket carb still pass emissions? Im not worried now cuz the truck is registered in Id but in case I move somewhere with emissions.
