is autolite 3922 proper spark plug for '01 1150GS?
thanks

The stock plugs are Bosch. There are many people who use Autolites, though.

Yes the AP3922 is the right "center" plug. (This is one step hotter than the AP3923, which is good in the 1100s.)

You can also use the NGK BKR7EKC-N (NGK part # 2095) in there.
If you want the iridium plug (longer lasting), the number is BKR7-EIX (NGK # 2667).

For the lower/outer plugs, NGK DCPR6E (part # 3481); or DCPR6-EIX (NGK # 8196) for the iridium.

All three of my oilheads have run noticeably better with the Autolites or NGKs than with the Bosch. When I do my routine throttle-body balance, I'll stick the Bosch plugs in there, since they'll show imbalances more readily; then when I've got it as close as possible, I'll put my NGKs back in.
And - not to start another debate, I just ain't listenin' - yes I do put a tiny bit of anti-seize on the threads: the threads are stainless steel, the heads are alloy, and I won't risk galling.
