1st of all I tried looking for various parts that are interchangeable for my GT650R and have found quite a lot actually so I thought I'd see if a thread like this helps.
I purchased 250 Kawasaki ninja coils that bolted straight onto my GT650R
I ordered a mofset regulator rectifier and took a while to come so in the meantime found a guy wrecking another GT650R with a working RR, turned out the thing had an aprilia 125 RR so I got it and works great for the interim.
So let's make a live doc, everyone copy the list, add your input and post it to help others.
I have been looking for an exhaust can for my GT650R and I really would like to know the outlet pipe dimensions of the where the can bolts to and specifically if the gt250 and 650 cans will work on each other?
I'm not sure on the Year models but if you know please edit and updat to correct me.
