engine filler cap

engine filler == oil filler.
Unlikely anyone makes this. Rocket accessories are not a high volume business.
 
nothings happend,but here in england there are that many arsoles who dont like to see you getting on,and a simple pull off cap like that,1 if you touring and its pulled off your screwed.2 if anyone bad enough to add anything to your engine,you are screwed too.
 
One member here has had someone put sand in the oil tank before -a real low act in my book.
 
Wow never heard of such a thing. Got a Harley fatboy with a open oil reservoir much like the ROCKET X, and has never been a problem. Kind of glad to live in a place where most people respect others property and leave it alone. Maybe OKLAHOMA (USA) ain't so bad after all.
 

More guns too...
