I recently got a pair of 1978 Sach Balboas from my father in law and I now have the first one running. It has a new air filter and a squeeky-clean carb but it will only go 20-22 mph with my 145 pounds. My FIL said it went 30 pretty easily when he put it up.
I'm not a mechanic but it seems like the throttle grip might bottom out before I'm at top speed. How do I adjust it so that it pulls a little more cable and opens up a little more?
Also, if there's anything else you can think of that I might check to get up to speed.
thanks in advance,
Steve "too slow" B
