I am in the process of modifying my 2011 KLX250S FI Version from Thailand by installing a Bill Blue 331cc Big Bore Kit and the Mikuni TM33 which he supplies bored to 34mm. After removing the FI unit, it seems the TM33 does not fit right with some gap. Anyone got a solution to this problem, i know there are many here who have converted from FI to Carb without problems, so i hope someone can help me out. Is there a bracket which i need to install to mount the carb? Referring to the photo, the problem area is highlighted in red circle, one side the diameter is 42mm and the other side the diamter is 50mm, so the carb doesnt fit the cylinder head. anyone who installed a TM33 faced this same problem? Is there an adapter or holder that can solve this problem?
