I have a 1997 xr200r and ive only had it for a few months. It seems to run pretty perfect has good compression goes through all the gears good and all that. Last time I went to start it it fired up first kick with choke all the way on then died shortly after which happens kinda often so i wasnt too concerned. Then i turned it to half choke and tried again which usually works but it didnt and after i few more kicks it made a loud popping backfire sound from the muffler. Now when i try to kickstart it it wont start and only backfires after few kicks or so. I recently crashed into a tree and put a pretty good sized dent in the muffler which caused the baffle to come loose so I ended up removing it. Im not sure if this is what caused it or not but it's the only mod I've done to the bike since getting it and it happened a few rides later. I have now removed the carb to check it out and clean it but other than that I'm not sure what to do. Any tips or input would be awesome. Thanks!
