Years ago Tony Hall used to produce these. They became harder to find than chicken lip-socks (rarer than hen’s teeth). Ivan Hoey (Australia) began producing these once more some years ago. Fits direct to the original clutch basket.
I scored a set and have been running them ever since. Love them. 3 fewer teeth on the primary gear, 5 more on the drive gear. Increases the transmission output while decreasing crank rotation.
Original … 27:72 … 2.66
Ivan +20% … 32:69 … 2.16
Together with Terry’s vescanite clutch dampers. The vescanite dampers don’t break like the springs.
Two of the better modifications I’ve done.
Ivan has just produced a new batch. Improved. The inner bush has been replaced with a needle bearing.
This is a small run. If interested he is now taking orders. Requires a deposit. Email contact here … ltr.management@bigpond.com
He can also do a needle bearing conversion on your stock primary gears. Dramatically improves gear and neutral selection. Also when stationary.
Includes needle, inner and thrust races, thrust washer, 3x screws/nuts and fitting instructions.
