I am about to change my oil for the first time but I cannot budge the allen bolt on the exaust is their a special tool I can get at my local wal mart to fit in there snugg and do the job.This is the last time I change my oil with the stock exaust.Any response is appericiated.

I don't know about Wal-Mart...

But I went down to Sears and bought a 6 piece Metric Hex bit set for my 3/8 drive set.

That screw/bolt....what ever...is a 6mm and I find I can get it out easy with a 8" extention on the ratchet.

Happy oil changing
