i have a couple of questions about puting xr650l plastics on my 98xr 600. forst off will it work? the main reasons i want to do this is because you can get alot more black plastics for 650l's and id like to do my 600 in black. another reason i ask is that i noticed that the 650ls tank has fins to direct the air toward the engine. does this help cool the engine much? could i put a 650l tank on my 600? one last question. if i bought an aftermarket 50l tank, would it come with the fins or would i need some off of a stock 650l? any help would be apreiciated.
