Have you ever wondered the difference between a Tiger 100 race kit manifold and a Grand Prix manifold?
This might be information you did not know that you wanted to know….anyway the left one is from a T100 race kit and the right one is a GP manifold. You can see de similarity with the fiber spacers and the “straight thru tubes” on both items. The tubes go in to the carbs and the head. I have to shorten the tubes for the use of TT carbs.
