2007 WR450F broken baffle bolts
Posted May 02, 2011 - 08:15 AM
Now my questions are -
1. Is this a common occurrence?
2. How do I fix it? Drill out the broken bolts and tap new threads or rivet the piece back on?
3. What can I do to prevent this from happening again if I use bolts?
I did manage to get the small baffle out after breaking all 4 bolts. Man was it stuck in place. Did not want to come out. The bike came with an after market Pro Moto Billet insert to replace the stock one so do not even need the stock one but still have to bolt or rivet it back together. Any help or advice is welcome.

Unfortunately the bolts broke off flush with the mount so nothing to weld to. I ended up going to my local dealer and they had a brand new muffler as a take off unit fairly reasonable.
Did you ever think about swapping the exhaust with a YZF exhaust? I just did that mod recently. I paid $100 for a complete 08' YZF exhaust with PMB spark arrestor/end cap from a guy here on TT. They're all over ebay for cheap if you decide to go that route. I have my old stock exhaust but the mid pipe is bent pretty bad. If you need some bits and pieces, let me know. It's just taking up space in my garage.

I was not aware a YZ pipe was a bolt on part. Good to know. I wish I would have known this a few days ago. Thanks Paul
It sure does, I read about it on here and then did the mod myself. It tucks in nicely inside the side plate unlike the stocker that sticks out far enough to kiss every rock, stump, or log when I lay it down. Here's a pic with complete 08' YZF exhaust.
