XV1000RH Mixture Control Vale (Read 3502 times)

Hurben Baynes(Guest) Ex Member	XV1000RH Mixture Control Vale 20.03.04 at 09:12:00 Hi, My XV1000RH started to run very roughly & the mecanic at the bike shop told me that the mixture control valve was faultly. They are expensive & there apparently isn't a new one in New Zealand. He removed it & said that the bike doesn't really need it. This worries me, does anyone know what problems could result from running without this valve ? Thanks, Hurben

Afaik that silly thing shall only avoid banging out of the exhaust when throttling down, so it isn't really needed. The bike runs fine without it, and a banging exhaust is funny. Bye, Georg

One explanation for the valve came from a local machanic, he said that the valve was designed to prevent 'blow-back', which in the old triumph's could blow the carburaters right off, although how you'd ever blow the carburaters off a TR1 is beyond me. Appreciate the feedback.

It only takes a screwdriver (like the ones you have at home) to help put things back like they were. Happened to me after a fillup.
