i dont belive it will hurt anything. i have a ttr-125l and i took mine out years ago. just seafoamed it changed the oil and spark plug about a week ago and it runs stronger than ever. make sure u check the plug to see if its running lean. if not you should be all set.

Take the spark arrestor out it will be fine. Id just get a whole new exhaust though.

I have a WR-450 and everything is stock, but my first bike was a TTR-230 and I took the scilencer out of that and it would sputter down low when you gave it gas, so you might have to re-jet the carb.
