Does this just give me a convenient low point oil drain, or is there something more to it?

Thank you, Rich

This sump plate allows you to let the oil out without removing the whole plate and potentially getting oil all over your hands, arms, exhaust, shoes, dog, cat and possibly (but highly unlikely) your budgerigar ........ all depends on whether you like a good mess or not.

And use a magnetic sump plug and get worried.

However, from time to time you need to drop the whole sump plate so as to be able to get your hand in the cases and fell around for stray objects.

Must be the last 750 owner on earth not to have a sump plate convertion , every body makes em ,first thing i made for my Laverda ,id wire the sump bolt thou , just for safety's sake .
 
The 2 750s I have are suffering a bit in this area > where the 4 studs go into the bottom crank case. The alloy is quite soft and thread fit has loosened up quite a bit over 40 years.

I think a plate with a plug is a good idea to help with that, as the 4 studs only need occasional re tightening when the plate is dropped for strainer cleaning.
 
Never had the slightest problem with the idea of the plate and strainer system, but as mentioned the weakness around the stud holes, which the new replacements don't suffer as they are stronger billet alloy. Have also never had a problem with any leak there, the thinnest smidgen of sealant on the old gasket every time. I loosen it so it drains the oil, then hold it with needle nose pliers and remove it, no mess. I also have mounted a circular magnet in the bottom so that all the oil passes over it, it thus picks up whatever of iron based particles as well as stray cam chain links, gear springs etc etc. No more messy than modern bikes with filter change.
 
Ricardo Oro rarely takes the sump plug out of triples or the plate off from twins, he loosens the inner gearbox cover, then places a shaped aluminium plate over the frame rails on triples or suspended on twins and the oil gushes out. I am never sure why he uses this method, and have concerns for the gaskets, plus what about cleaning the sieve? but that is what he regularly does.

Each to his own. Dump and fill is pretty common practice. I agree with you Clem that it is good to check the strainer at least now and then. I also clean off my magnet. The most important is to actually do the oil change often enough.
 
with TOG I do it every two or three years no matter if it needs it or not.

Well, seriously, I never do it by mileage, or date, I do it before any big trip, and by big I mean more than 1000 miles away from home, never changing the oil when away, no matter how many miles, in the past I have dumped it in a sandy or soft lay by and refilled with fresh, (I know, I know environment! this was years ago) but no more, I also have the policy, that if it needs a top up it needs a change, the half way mark on the dipstick might take 2, 3 or 4 thousand miles to get there, cant recall, and don't monitor.

Rich,

That"s my Ebay shop and plates, & fitted to my twins, any other info please pm me,but think it"s all been covered here.

Shaun.
 
Thank you for all the replies.
The bike I bought (in March) has not run in at least 20 years (that is the seller's estimate) and at the rate I'm going, won't run for another five years.
But now I have some good info, and I will be buying one of these and installing...after I disassemble, clean and reassemble the engine and the rest of the bike.
Best regards, Rich in TX
