It seems that all the information on here about the 640 airbox mod are ancient, and require parts made by users. Does anyone have any information on where i can get my hands on a link pipe for a K&N filter or a metal gauze for the side pannel?
I've got a 2003 Ktm 640 LC4 SM btw
Hello! New member here... I'd have a couple of questions for 640SM/Duke 640 owners. I see that the BST "slide" holes can be enlarged to make the carburator response faster... is it worth the effort?
Another question: my bike still has the original air filter... is it worth the effort of cutting...
I Got Tango'd after back to back test rides a few weeks ago on the GS, Multistrada, and 1190.
Just arranged to collect my new 1190 Adventure on Saturday.
In reality I ride on tarmac (hence not getting the R) but I might be tempted gravelly stuff if anyone in the Kent Sussex areas...
Was wondering if anyone had any issues with the moto hooligan airbox mod.....with reference to mud , crud, water, salt and genaral british road crap causing any issues with the mod....also can you order up replacement filters here within the uk from k&n??
