Has anyone out there who posts to this site set up a L280 with triple 40mm Delortos? I know that many out there have, but I cannot find any good data on jetting correctly. I set it up with a recommendation from an English racing group, but it runs real rich and stinks, with lots of backfiring until it warms up. Carbs have been overhauled and are spotless. Any data greatly appreciated.
