Reason for the stock air box ?
-
Hey all, I have a 99' dtr and I'm new to 2 strokes in general. I was wondering if there is a need for all the small boxes along the air tube as it don't help when working on the bike haha
@mbmO8 This explains the YEIS box between the carb and reed valve better than I can:

When working around that area it's not that difficult to remove as long as you have a decent pair of pliers to squeeze the clip on top of the reed block, just stuff a rag in the hole until you refit it. The one behind the carb on later bikes, I've never owned a DTR with one of these fitted so maybe someone else can help out explaining this? I see a lot of people blank these off with the lid off a Coke bottle.
