Noticed quite a bit of discussion regarding aftermarket tanks lately, so I'm throwing this out. What's your opinion for an aftermaket tank for the 'L', and what size is best? IMS, Acerbis, Clarke? 4.0, 4.3 or...? The stock tin can and "wings" aren't cuttin' it. It's time for a (much needed) upgrade. My 98 has white plastic. Thanks in advance.
