Hi All
Having got the 3/6/8 CS bitza water cooled, at last, I've been playing with the linkage, trying to cut down the hunting.
After fettling everything, a mix of original and Indian parts, I had it down to an 8 rpm flutter, idling or on load.
I wanted to put a light spring on the free end of the rack to spring cut down the backlash but couldn't be arsed to strip down and drill a fitting into the rack, and anyway there was no likely spots for the other end of the spring.
I came up with the idea of tensioning the whole thing against it's self using the holes in the clevis pins, a spring from a set of twin SU carbs and a curved link knocked up from a 2.5mm welding rod
I had to slightly increase the tension on the governor spring, the flutter is now down to around 4 rpm, result! I don't think I'll get much better
Hopefully the photo explains all......
Cheers Stef
