Nfieldgear sells a kit with 5 filters and all the o rings needed. Pretty handy.
I've gone back to my roots. British 1 lunger, stump puller.

Is it true that fully synthetic oils such as Motul 300v factory line 15w50,
have twice or thrice the drainage period, in comparision to mineral oils ??
If that is the case, then the extra cost should not be deterrent.
Would appreciate practical advice on oil change period of synthetic oils. Thank you all and Mr. Moderator :)

When synthetic oils first came out back in the '60s, the original idea was not to ever have to change it. Just change filters every few thousand miles. The molecules in synthetic oil don't tear apart and wear out like mineral oil. However someone seems to have forgotten the other contaminants that collect is oil that filters have nothing to do with, like water, gasoline, etc.
So, presumably you can run synthetics longer, but the other stuff can still eat away at your engine, so it's not advisable. 
You buy synthetic oil because it's marginally better than syn/mineral mixes, but either of them in the motorcycle blend are quite adequate. 
Be sure to get a motorcycle blend or some truck oil like Shell Rotella is good. Do not put automobile oil in a bike!

bare thanks for the details.
the question is when should one
change a fully synthetic oil on a moto.
I have read reviews on Amazon, where
people have shared that even after
5000 to 7000 miles the oil looked like new.

If you're really curious you can send samples in to be tested periodically, then you'll know when it's time to change it.

If you put synthetic or any other oil in an RE after a normal oil change, it will look dirty in 100 miles or less!. They don't drain the original very completely!
If you have the drain plug under the crankshaft, be sure to use it!

Thanks Arizoni (and everyone else) for your replies. Your suggestion sounds good to me. I did have concerns about the small quantity of oil remaining after draining,and what effect in may have on any new oil.
