Hi, I have a 1988 DTR (3BD1 model) with a Mikuni carb. Does anyone know what size the standard main jet should be? Hanyes say 125 can that be right when the later models are 210. Cheers Clarkie.

So if you click on the links that take you to the carb that you have on your DT it tells you (amongst other things) the spigot diameters on each end of the carb. If you then want to try a bigger carb you can t...
