Dont buy the kdx snorkel... i bought mine in the beginning, now its sitting on the shelf with all the other stock parts... just take the stock snorkel out of the airbox.

I just pretty much did all this stuff to my KLR650, i did the klx a long time ago, drilled slide, rejetted, and a/f screw... mine runs great. full big gun exhaust. uni filter.

 

The sprocket 514XK-13 was on back order from Sprocket Specialists for about a month, so I called my dealer and ordered one from them. We'll see if it works.

 

The counter-shaft sprocket nut typically is almost impossible to remove, if you don't have much experience with bikes I suggest you let the dealer change it and sorry deej but you are wrong, if you put the 45 on the back you will need a longer chain. From memory stock is 106 you will need 108 links
