It says as follows:<br /><br />"Though still lagging behind its US competition in offering low-pollution two-strokes, Yamaha is rapidly catching up.<br /><br />The company now has a mix of carbie, EFI and DFI models. All of these have V-six powerheads, but the 150, 175 and 200 carbie models have a 90| vee, while the Z200N and 225 have a 76| vee.<br />this is from Boatpoint website in Australia - rune by NINE MSN. It is the biggest site here. It says of the<br />All engines have variable oil-injection, where oil is injected at the reed valves via individual feed lines, from 50:1 at WOT down to 200:1 at DST. This system eliminates having to run the carbies dry before storage but does prevent the butterfly throttle valves from receiving lubrication, leading to possible verdigris build-up. It's also intolerant of 'gelling' in the feed lines from mixing different brands ".<br /><br />Is that right and does it apply to my 93 115 V4 - I know that this was discussed recently but I am re-invigorating it. If gelling is a problem how do I clean out the lines and supply to start using Yammy oil given that I dont know what the previous owner used?<br /><br />Cheers
