• Hey guys and gals.  New member here...I’m in the process of having CT racing bore my cylinder +1.5mm on my ‘87 LT250R and was curious of where to start jetting wise.  I have not received the carb yet(36mm Keihin PWK), nor do I know what jets are factory installed.  I am just curious of a good starting point.  I have a good bit of money in this thing and I want to do it right!  Thanks guys!

• I’m not familiar with the keihin carbs but someone should be able to help out with the info you’ve given also what altitude are you running at?

• There is a thread on this site that talks about Jetting and elevations which should get you close enough to do a plug chop
