Plastic pieces... Form or function? (Or both?)

[Ncdan]

I change the filter in my breva every other oil change...  I didn't put much thought into it, that's just (roughly) what the manual says....  at my meager milage, it equates to an oil change every year, filter every other year.  I don't pay much attention to the milage b/t changes because I've only ever ridden it 5k+ miles in a year once... I'm usually about 3k a year, depending on whether I have the v65 running during riding season.

This year was a 'heavy service year' which means I did oil & filter, valve adj & plugs, trans & gearbox oil

next summer just an engine oil change & valve check/adjustment

Be careful Mayor as that technique makes way too much sense, lol. By the way that’s how I do it also. ]

I was putting some heated grips on my Breva yesterday and gearing up to do another oil change (this time filter included).

Removing the plastic piece at the front of the oil sump and in front of the fuel tank is a pain. Why are they there other than for looks? Is anything lost by getting rid of them entirely?

Willard, far as I'm concerned that  bottom plastic on the front of the 750 Breva motor is just for looks and I took/left it off since I have to remove both plugs to drain all the oil when it's time to.

My T has no oil filter, so I changed oil every 2,000 miles. There was no reason to drop the sump until after the flood, at about 60,000 miles. Everything was clean as a whistle then, though after the post-flood rebuild the big end bearings and crank journals got scored so obviously I didn't get all the grit out.
