Gents,
I have terminally rounded the SOFT 12 mm head on the oil filter bolt on my 1981 GL 1100 trying to remove it. I wish I could blame overtorqueing it on someone else, but they don't call me gorilla for nothing. It's still not out but I'll get it somehow. Since it will need replacing, I have seen references on this site to aftermarket replacements with larger, harder heads. Any suggestions as to where to purchase these would be greatly appreciated.

You might try using an angle grinder to create two flat sides on the bolt head, then you can get it loose with an adjustable wrench.

I had to do this to about 10 stripped Phillips headed bolts on an engine once where the P/O had attempted to remove an engine cover before me, and yes, they were in there tight too.

So, you need a larger head to put MORE torque on it?:raspberry:
I generally just tighten them until they spin free........

A good pair of vice grips and a hammer and chisel. One sharp rap.
Pull on the grips while striking the head from the side.(Two man operation)

To remove, I use a large channel lock plier

i have also read on here that the larger heads ultimately cause larger problems.

at the price of that bolt from saber i'd just go ahead and replace the whole assembly with a spin on adapter http://www.ebay.com/itm/OIL-FILTER-...Parts_Accessories&hash=item460e0ce49a&vxp=mtr

but then again u can get an oem bolt for even less than saber

no reason why the bolt needs to be tightened more than about 10 ft lbs

Problem solved

Many thanks, Neoracer. Got the thing out with an EZ out. Ordered the adapter for just a bit more than the new OEM bolt was gonna cost ! Been meaning to add that, but I remember them pricier than that. Installed the dipstick kit a while back. Future oil changes will be a snap.
