    Am curious about what 4LS drums will play with BMW forks (and which forks), willing to go for K forks. Thinkng TZ, Oldani, Suzuki 750, Grimeca

    usually the garage
    I had the Suzuki 4LS on a Metisse T500 road racer and it was a right PITA to keep set up properly - shoe wear, differing stretch in the twin cables and so on. They have to be adjusted right to work effectively, otherwise you are dealing with multiple narrow pad widths gripping the drum out of synch. Unless you have some genuine need for a 4LS setup I'd stick with a properly sorted 2LS as they are a better system for normal road work.

    the Suzuki 4 shoe brake is way wider than the stock brake. you will need custom tripple clamps made to use the stock forks. JB
