250-500cc 2012 WR300 Starting issues driving me nuts, can anyone help?

I'm not sure what your point is here. Are you telling me that it makes no difference to your engine if you run less oil? Your weed trimmer and chain saw information kind of through me off.

The manufactures recommended ratios are based upon the jetting which comes with the motorcycle at the time of purchase. As far as engine life is concerned, the manufacture does not have the customers best interests in mind. I know you have changed your jetting since purchased, even carburetors a time or two away from manufactures specifications. Regardless, I was only try to help you gain engine life, not trying to gain your business.

^^ Kelly is better at explaining than I am.

im sayin i think we could all safely use less oil if a company like Amsoil can make an oil that will keep a chain saw alive [when was the last time you didnt have your saw pinned WFO] then do we need twice as much to keep are bikes alive?????has anybody done any real testing on this since the advent of ceramics a hi end synthetic oils??????

Wasn't this thread about kick starting a 300?.
I just bought one and there sure is some compression there!

I've had my 300 for a whopping five months now and it seems like I've tried every two-stroke oil made thus far.
I like the Maxima 927 at 40:1. The smell reminds me of the good ol' days. To the point... I think it may even kick start better when I use it....

32:1 with good jetting will never ever hurt a bike. 60:1 has potential for damage; 32:1 doesn't.

Bean oil smells good, also the highest hp.

More oil = more compression = better starting. Also, add an iridium plug which helps with the starting and they last a really long time.

Pretty happy with my tune now, I am now at 40:1 and I have the mikuni as good as I can ask for. Easy starting, running clean and strong but will try a different pre mix oil as I'm still getting excess oil out the exhaust. It's beginning to loosen up a little more, it now has about 250km on the odometer.

What jetting are you running?

Jd kit, 420 main, 32.5 pilot, number 5 slide, red needle on second clip, air screw 1.5 turns out, adjusted float level

Are you at sea level? I switched to white 3 and 410 main for elevation above 5,000 feet. Might try white 4 due to warmer temps. Adjust main only if hot weather or you ride often at 5K elevation or above. I ran 32:1 with spooge on white 4 and a 420 main. Switched to white 3 and 410 main with same ratio and no spooge. IMO, the JD kit is very precise.

I am at sea level

try white 4th clip then.

Ok, will look into it.
