thundercatnovice Posted April 8, 2006 Share Posted April 8, 2006 I have just inherited a Thundercat and it won't start. I have replaced the battery. When I try to start it the engine trys to kick in but it doesn't start. The bike was left standing for a while and started every month, I have been told by a Yamaha dealer that it is likely that carburettor needs draining, how do I do this?

Moderator YamaHead Posted April 9, 2006 Moderator Share Posted April 9, 2006 to the forum T-Catnovice There's a drain screw @ the bottom of each Carburetor fuel bowl.....with a rag under the carbs to soak up the fuel, just loosen each screw a few turns(NOT all the way out)....till the fuel stops draining....then retighten. Then drain the tank through the petcock until empty. Reattach fuel line to the carbs & refill the tank with fresh petrol. Might wanna clean & gap the spark plugs while you're @ it. Then hopefully she'll cough to life @ start-up Link to comment Share on other sites More sharing options...

Pete Posted April 10, 2006 Share Posted April 10, 2006 And I'd add a fair bit of Redex carb cleaner into the petrol as it will help to clear out any shit in the fuel system. Link to comment Share on other sites More sharing options...
