jasper Posted May 19, 2008 Share Posted May 19, 2008 I have an N-reg Yamaha TRX with a rather bizarre carb problem. Basically I stored it over the winter, had it running in the garage once to charge up the battery, and then on the first ride a few months ago, noticed that at 3/4 throttle, if you opened the throttle to full, the bike died completely. However, rolling back the throttle gently allowed the bike to run ok again. It was fine before the winter, so what could have changed? It sounds like a main jet issue but it was running fine before I put it away. Anyone got any ideas or had a similar problem? Jasper Link to comment Share on other sites More sharing options...

The carb is overfuelling so needs a service. Link to comment Share on other sites More sharing options...
WiCkY Posted May 21, 2008 Share Posted May 21, 2008 It's called a rich cut. The carb is overfuelling so needs a service. prolly caused by worn needles and emulsion tubes (a common problem with TRX's, TDM's and XTZ's.) try www.carpe-tdm.net fer info and pics on how to replace these items.
