Banchetta Posted December 19, 2003 Report Share Posted December 19, 2003 Im running 32:1 with Amsoil Synt. Series 2000 racing oil... HOWEVER the oil states its "ideal for" 50:1 I like the quality of this oil and their reputation!! Anyone run this oil with a different ratio ??????????? I'm running the same oil w/ a 40:1 ratio...I run it in my sled, but I'm not sure if I like it in my shee....I used to run Castrol at 28:1 and loved that oil the best.....

Demon350 Posted December 19, 2003 Report Share Posted December 19, 2003 i run castrol 32:1 fully synthetic, no problems, my plugs are a tan colour and even when i ran 20:1 no probs Quote Link to comment Share on other sites More sharing options...
bansheewizard Posted December 19, 2003 Author Report Share Posted December 19, 2003 thats what i dont understand everyone runs theres 32:1 im prety sure that is more oil that im runin 40:1 and ty dont foul plugs 32:1 is more oil than 40:1 rite or is 40:1 more that 32:1 ???????

Banchetta Posted December 19, 2003 Report Share Posted December 19, 2003 Mixture isn't what fouls plugs...I can run 20:1 and not foul plugs. I normally run between 24:1 or 28:1 and never fouled plugs.. If you are, then your jetting is off...maybe too large of a pilot jets??....

Banchetta, so are you saying that a leaner jetting setting can compensate for a richer mixture without any other effects? I know a bit about mixture from my RC days But there has to be an optimal setting somewhere? I don't think you should run 100:1 and jet it real rich????

Banchetta Posted December 19, 2003 Report Share Posted December 19, 2003 What I'm saying is that the richer oil mixture shouldn't be fouling plugs...I prefer a 28:1 mixture and leaner jetting....After all, the oil is YOUR lubrication.....Why lack on that?? Not enough lubrication and your shee will actually lose hp from friction and will wear your rings considerably..If your shee is fouling plugs, then the air/ fuel mixture is too rich causing the shee to flood out and foul the plugs...Too much gas and not enough air will cause the shee to not be able to burn all the fuel and foul out the plugs...Every shee is a little different and a lot of us should try different jetting regardless of advice...We can get most shee owners close to jetting, but you should adjust the jetting to YOUR shee, since every shee is different in different areas of the world....From my jetting experience on over 20 different shees in my area, I've never seen a shee like a larger pilot then stock or 27.5, but other shee owners have found the larger pilots to work better for them.....I can't see how, but I'm not in their location or terrain....Hope that helps...

PassionRE Posted December 19, 2003 Report Share Posted December 19, 2003 Back your pilots down to #50's, set air mixtures at 2.5 turns, sync idles and then cables, re-adjust your air mixtures to highest idle after a complete warm up(hot) and then richen up air mixtures until 50 rpm is lost from highest idle. Then, readjust idle speed and repeat process again. Extended idleing will foul plugs, 40-1 should be ok...Jim Quote Link to comment Share on other sites More sharing options...
sean10 Posted December 19, 2003 Report Share Posted December 19, 2003 What kind of bull shit is that? You DON'T jet your carbs to what oil ratio you are using. You jet it according to plug readings, and how much air your motor can pull in and get out. What you stated here: Boonman i dont know how you dial your bikes in but try running your bike after you dialed it in at 32- 1 and than mix it at 40-1 and tell me if your bike runs the same. Maybe you just dont give a shit wheter your bikes run like crap, thats a different story, and of course you look at your plugs for the reading! Thats a given.

Oil ratio can make a difference, although in some cases it isnt a big deal.

Not enough lubrication and your shee will actually lose hp from friction and will wear your rings considerably.. And I couldnt agree with Banchetta more!! You actually gain performance by running a gooey mixture because there is less friction between the rings and the bore. Plus you get more static compression by running more oil.

MX Black Beauty Posted December 19, 2003 Report Share Posted December 19, 2003 I run 50:1 and use Bel-Ray Mc1 oil. I haven't had any problems running this. I'm running 34mm mikuni TMX carbs on my shee and my main is a 430 right now(32 degrees outside) I can't see why your running so low of a main. Go back to your stock carbs you'll probably notice a big change with your fmf's. When i had my sst's they recommended a 260 main for the stock carbs. I guess what I'm getting at is if you have to lean out your 35's to a 158 main then you are defeating the purpose of having bigger carbs and they aren't doing you any good.

Banchetta Posted December 20, 2003 Report Share Posted December 20, 2003 Justintoxicated: A 40/1 mixture is leaner w/ less oil then a 36/1 mixture....looking at that pic, I'd say your either detonating since all the damage is perfectly centered or your running hot...What octane are you running and what is your compression?? Lefty: I learned that the hard way w/ my personal watercraft (jet ski). I had a big bore w/ high compression heads. The racer before me leaned out the oil injection and I was going through a set of pistons in 4 hours. Grenaded one of them. Finally I figured out the problem and WOW!!! Increasing the oil was an incredible difference... I gained 5mph on top speed and getting there was insane....That was all the proof I needed....I don't care if the oil is synthetic or not, I wouldn't go over 32:1 on any shee.....

Banchetta Posted December 20, 2003 Report Share Posted December 20, 2003 I think what he is sayin is that larger carbs could hurt more than help if you don't have enough internal motor work done... I know this from experience....I was running a 165 main for peak performance is still lost 8hp w/ my 34mm PJ carbs...I went back to stock... I also had a hard time getting throttle response, idle, and starting....W/ too large of a carb and not enough velocity, your carb won't run very efficient and will be hard to tune....W/ a list of your mods we could probably help a little there...

g-lo Posted December 21, 2003 Report Share Posted December 21, 2003 i use motul and i mix mine 70 to 1. i have never had any problems. i just rebuilt my top end and it was clean and no damage. when i used klots at 32 to 1 i had all kinds of carbon in the intake and on the piston.
