I have tried everything to get my 74 Commando with a roadster tank to stop vapour locking. I drilled out 3 additional holes in the ring under the cap; I cleaned it thoroughly...nothing seems to help. I have to ride with the cap open or open it periodically when the bike starts to stall. It is a standard steel original roadster tank with the standard cap. Can anyone give advice? Thanks!
