  1. The most accurate way is to measure the weight of the needed oil. I calculate what I need and then pour it into a cup that is sitting on top of a digital scale.

    My exhaust is clean but we are talking about a universal principle here. It is possible that spooge presence/absence is a good way to tell if you have too much oil in your gas when trail riding but for racing applications you want too much for better ring sealing and best power. But then again you are back to choosing to use a good ratio calculator or doing trial and error thru a few rides. With the manufacturers oil data and my calculator I can tell for whatever oil what the minimum and maximum amount of oil is, no guesswork and no prolonged trial and error. http://www.dragonfly75.com/moto/oil.html

    Now there's a way to figure it out without the risky trial-and-error method. Check out my new video- Maximum Safe Fuel/Oil Ratios for 2 Strokes at https://youtu.be/O7iErMwWIB8

    they only changed the 125cc to 40:1, and the little engine still has the 60:1 recommendation. just goes to show you that you can't always trust those that you think would be trustworthy to make good decisions.

    KTM is usually pretty smart but they are tripping by recommending Motorex Power Synt at 60:1 for their little bikes. Maybe they like doing warranty repairs.

  7. There are two ways to determine fuel/oil ratio: 1) for race engines that you want the best power from them you just use a lot of oil, close to 32:1 (of any type oil with a viscosity of at least 2 @ 200*C). You also want this ratio for air cooled cylinders to prevent piston noise. 2) for water cooled engines and you are not concerned with absolute best power and are on a budget and just want adequate protection, then you can use my oil ratio calculator to know how high you can go on fuel/oil ratio and still be protected. From 65cc to 250cc Honda recommends 32;1 of their full synthetic HP2 oil, and Yamaha recommends 30:1 of their mineral non-synthetic Yamalube 2R oil. My calculator says Yamalube at 30:1 is good for the tiddlers up to 125cc (reving to 12K RPM) and 34:1 is good for the 250cc reving to 9500. So Yamaha is doing both- recommending lots of oil for good ring sealing (good power) and recommending according to the oils viscosity. Honda is in over-kill with a high viscosity (3.2 @200C) full synthetic at 32:1 and they could just as well recommend using about 4 other oils that according to their viscosity would better match that ratio. But the HP2 oil is cheaper than they are so the temptation is to stick with it. But consider this- when you use more than what is needed of a high viscosity oil for decent protection then at low and mid range RPM you have more power loss due to viscous friction. So for owners of water cooled engines the question presents itself if we want to spend more money for best power or use just enough oil for decent protection if we aren't racing.
  8. I ride an air cooled bike and these type engines have more piston/cylinder clearance and make less piston noise with more oil (lower fuel/oil ratio). So I advise for air cooled engines that people use a semi-synthetic that is a blend of synthetic and mineral oil. It is less viscous and so more of it should be used to get the same final mixed viscosity. They are typically used at 35:1 instead of the 50:1 typical of the high viscosity fully synthetic oils.
  9. SS - It is Motul that recommends their 800 Off Road oil at 50:1 for motocross. Motul 800 is one of the high quality full synthetic oils that can be used at high ratios because of the oils high viscosity and viscosity index. Here is the page showing Motul recommending 50:1 http://motul.speclube.com/wp-content/uploads/products/specifications/800_2TFactoryLine_OffRoad_8371_(GB).pdf Other really high viscosity oils are Honda HP2, Motul Kart, ELF HTX 976+, Bel-Ray MC-1, Repsol Moto Racing, RedLine Allsport.
  10. I have no problem with constructive criticism. OK so you got some chocolate colored soot at the silencer. If you want to use more oil than is necessary and have to deal with soot and deposits and spark plugs that foul more often then that is completely your choice and I support your right to decide for yourself. Be aware that using too much castor also means you have to take the engine apart more often and clean the rings and their grooves.
  11. for 9000 rpm both need 40:1
  12. "Legend ZX-2R is an ultra premium, non racing, 2-cycle lubricant formulated for the ultimate in engine protection. Recommended for older engines, trail, and other non racing applications." "Legend ZX-2SR is a high performance 2-cycle lubricant formulated for racing and maximum performance. Recommended for newer engines and high RPM applications."

  14. I wouldn't pay any attention to that theory unless it was proposed back in the day when everyone used mineral oil. If so then it only applies to those oils. Synthetic oils leave very little carbon deposits if any at all. Your fuel/oil ratio exists to make sure you have enough oil to protect metal parts. Too little oil and rings wear fast. Too much oil and your engine wastes power fighting viscous friction.
  15. my calculator says 27:1 for Interceptor op to 12,000 RPM water cooled
