I recently bought a replacement IMS tank for my 07 450. I thought I could make an entire 2hr harescramble on a tight wooded course with the stock tank. Nope..... 1hr 47min yes, 2 hr no. When taking off the shrouds (for the first time since I bought the bike used a couple of months back) I noticed the bolts that hold the shrouds to the tank would just spin and not loosen. I took a flat blade screw driver between the shroud and the tank to apply pressure. I ended up popping both of the bolts out of the holes in the tank. The inserts were covered in what appeared to be MSR Quicksteel or something similar. Is there any way to repair the inserts or should I just put the tank in the plastic recycle bin?
