[QUOTE="snaggleXR4, post: 187028, member: 24395"] Hey, On your 97, the baffle will come out. Remove the screws and pull like crazy. It will be stuck pretty darn good but it will come out. Keep in mind it will be very loud. I don't recommend even trying unless you plan to put in a Vortip or another aftermarket baffle. Yes, I did think about the backfire because of being lean. That is true. However, you said it backfired while putting around in 2nd gear. To me that means your pilot. With a #60 pilot and your baffle in, you can't be anywhere near lean. You never did mention your main jet. Maybe you are lean there, but if it is stock, then it is a 162, and that's not lean either. Maybe, as you mentioned, you oiled your airfilter too much and for that short time, you were way too rich. If you don't get backfires again, maybe that was it. Check out bajadesigns.com. They have a XR400 section, and they have the dual tapered needle, and even a different slide that they will trade in for a discount. Good luck, and enjoy your bike. [/QUOTE]
