Thank you for your reply. I've ordered a L&T 3 disc wet clutch along with the needed pipe.A Tomar, made by Quartermaster, Td22 clutch will not work properly with anything other than a sportsman (small carb 4 or 3 hole can) Yamaha. with max engagement around 8200 iirc.
I've seen some Tomar Td23-3 disc dry clutches used on pipe engines but I question the reliability.
