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?

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

Thanks for the welcome.

Thanks for the advice, I will try it tonight and fingers crossed all will be well

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.
