I re-painted the oil tank on my Suzuki B100p and was wondering what type of oil to put in it. It is a 2 Stroke and was wondering if Senthetic is ok to use. It also uses a Posi Force Injection system and was wondering how can check to make system is working proper. I just did my permit/Balance test on the bike and want to make sure it working proper. I was told I didn't need the turn lights due to the age, however I put a set on from Ebay which actually look pretty good.

hi,
yup, pre 1986 bikes dont need inicators.
there is a way to test the oil oil pump which involves running the bike with the 2t feed disconnected (with a bit of 2t oil in duel tank) & seeing how much 2t comes out at WOT.
its in the wsm, personally wouldnt bother. pumps either working or not.+ youl soon know if it isnt Wink

cheers

hi,
i always use fully synthetic on my later sports 2 strokes, cos thats what the manual stipulates.
the 80's gammas, i use semi or fully synthetic as that what the manual states.......
seeing a pattern here?
however, i wouldnt put that mineral crap sold by supermarkets, anywhere near any bike, best left for lawn-mowers imo.
at the very least i would use semi-synthetic in ANY 2t.
i know your manual MIGHT specify mineral 2t, but oil has improved a bit since then, so i'd always go for at least semi.
im all for saving a couple of quid here + there, but 2 stroke oil is not not either of these situations.
pay the extra 2 quid a litre. your bike will thank-you for it, by way of less carbon/sh*te building up on exhaust/plug etc,

cheers,
GAZ

There ought to be a procedure for priming and testing the posiforce system in your workshop manual. As has been said already, this would normally involve running the engine on a small amount of pre-mix with the oil line(s) disconnected until oil is seen to run through. There is then usually a drip count to determine if sufficient oil is being delivered.

If you do not have a workshop manual, I'd strongly suggest getting one.

If it's anything like my old Suzuki T500 which had a direct oil injection system, there are some small non-return valves in the banjo unions which can become stuck after a period of disuse.

A quick and dirty test is to make sure you have a haze of blue smoke from the exhaust after startup. If you're seeing that, there is at least some oil getting through.

Arrghh! A Bloop. Rode one once & as I was going through the local council estate I took an unexpected football to the chest that knocked me off the back of the bike Smile
