I had one of this era back in the day. From what I can remenber heaps of balls but handled like a bucket. It used to headshake something bad like real bad. Spent a heap of money with Terry Hay for not much improvement. My brother had a YZ250 same year at the time suspension on that was sweet motor wasn’t as punchy but was just a s quick.

Yeah I did it in 2008, I high sided it at a pretty reasonable speed, which shook me up a bit, still finished but wasn’t real happy with my effort. First time for SB_250y

Yeah i agree if the female thread is damaged or stripped a Helicoil is an option but they also have limitations. But from the experiences I have had even with a helicoil over time you will end up with the same issue. That bolt is a drain bolt from the filter chamber. Whilst the bike is running rubbish accumulates in the space between the end of the bolt and the end of the hole. When you remove the bolt it drags a little of the rubbish out and onto the thread and the rest stays in the blind hole. Over time that much rubbish can accumulate that the bolt botttoms out on the shit the more you tighten it the quicker it stuffs the bolt.
Try winding the bolt in by hand if you can’t the hole needs to be cleaned out. Those drain bolts are soft as.

My brother and I used to have the same problem on our 04 and 05 WR450’s we tried replacing the bolt but it would gall the very next time, learnt you should run a tap with grease on it down the hole every time you do an oil change alot of rubbish accumulates in that drain hole from the filter. I also found giving it a good clean with Contact cleaner through the hole and back into where the filter sits helps too. Had no issues with damaging the bolt since on our 04,05 or 09 WR’s. Its a 6mm bolt.

I have always used Micks Metal Craft in Kings Park. 9755 7137

Melissa Av kings Park next to Pirtek. He’s not the cheapest around but IMO his weld quality is pretty awesome.
