Hi guys,i am having some problem with my tdr(3sh).I can't start my bike with starter.When i press the ignition button the engine revs but i doesn't start,not even with the choke.If i bump start it it fires up right way and works perfect.I have changed the plug with a new one and the bike has done about 3000 miles since a complete rebuilt.Also checked for air leaks and everything seems ok.
