    Redline SI-1 in 7 month old gas

    If you test the IAC electronics and they're good, then you can also try cleaning the IAC with intake spray cleaner to see if that helps. They do get carboned up with time. If it's bad, then it's bad, but sometimes a good cleaning will do the trick. Also inspect the IAC gasket base and or o-ring...

    Redline SI-1 in 7 month old gas

    See if your friend can measure the fuel pressure on the fuel rail to make sure it's in spec. It should probably be somewhere around 45 to 50 psi, but check your service manual to make sure. If the fuel pressure is low, then you'll need to determine if its a clogged fuel filter on the pump inlet...

    Redline SI-1 in 7 month old gas

    Did you friend put a scanner on the vehicle to determine that your mixture is lean or are you assuming it's lean because the check light is on? If he put a scanner on it, what was the exact scan code(s) read? Does your friend have access to equipment to sniff the tail pipe to check a/f ratio...

    Ping on Regular Fuel Only?

    There are many different reasons why your engine may be pinging, but it takes experience, understanding and good troubleshooting skills to narrow things down. Did you buy this vehicle new? Has it always pinged on 87 octane up hills or did the pinging suddenly start or gradually start...

    Temperature and Bearing Wear Relations

    I also don't think the oil would get hot enough to melt the bearing, but I think the concern is the babbit layer of the main bearings, which is often extremely thin (i.e. 0.0005"). The motorcycle crankshaft main bearings I've worked with typically consist of 3 layers; steel, copper & the babbit...

    Motorcycle Chains!

    The WD40 is simply keeping your chain cleaner and free from abrasives. WD40 provides no barrier protection against wear and it's corrosion inhibiting properties are quite limited, but you're already ahead of the game by keeping your chain clean compared to the bikes I see week after week with...

    Proof of LC performance

    And also note the very low flashpoints listed in the Blackstone samples compared to what's listed in the MSDS. So is the Blackstone sample data faulty or has LC20 changed or is (or was) LC20 really a 10wt with a low flashpoint?

    LC in power steering system

    The dosage I've read from Terry Dyson and from Molakuke is... "For power steering systems, 0.5 oz. or 15 cc. Check Power Steering oil level and do not overfill. Check when Power Steering Pump is hot." I've never tested this product in a power steering system, so I can't give you any first...

    Why Rotella?

    Yes, Rotella is more beneficial to motorcycles when compared to various PCMO's (Passenger Car Motor Oils) because it shares some of the common strengths found in motorcycle specific oils, such as being able to typically handle higher temperatures, higher shear, higher loads, heavier duty...

    Glazed Clutch Plates

    I have done some research on this and you're simply wrong again and again and your credibility is quickly disappearing. For the last year or so, Mobil’s motorcycle oils have contained moly in the add pack. ‘Bob’ the oil guy is also a motorcycle enthusiast and the oil he uses and recommends to...

    Lubricants for motocross use.

    Take your favorite grease and put a dab of it in the palm of your hand. Now mix in some water with your index finger and continue mixing it vigorously for a short while to see what happens. Does the grease stay put or does it come apart, thinning out & losing its tack, etc? Does the grease still...

    auto rx or LC20 which is best?

    Use 1oz / quart for the intial dose (i.e. after every oil change). Use 1 - 2oz every 1 thousand miles afterwards. When you change your oil, then you go back to the intial dose again, which is 1oz / quart and follow that up with 1 - 2oz every 1 thousand miles afterwards, etc, etc, etc. It's...

    Glazed Clutch Plates

    Do you even realize that Mobil's Motorcycle oils and 'some' other brands of motorcycle oils DO in fact contain moly? Saying that oil containing moly causes clutches to slip is like saying foods or beverages containing alcohol will make you drunk. Too much alcohol in your system will certainly...

    Motorcycle Chains!

    Think about this for a few minutes. Most oils, greases and waxes don't have much in the way of load carrying capacity unless they're replenished. Oils, greases and some waxes are good at collecting abrasives, which is bad for your chain & sprockets and they can easily washed off your chain. For...

    auto rx or LC20 which is best?

    Use 1oz of LC20 for every quart of oil on the initial fill for new oil. Then use just an ounce or two of LC20 every thousand miles after that.

    Glazed Clutch Plates

    Friction modifiers by themselves aren't necessarily bad, but a friction modifier that 'Reduces' friction can be a problem. There's no mystery here! The friction specs for a wet clutch are clearly spelled out by JASO in the MA spec for 4 stroke oils. The dynamic friction index must be 1.45 or...

    Ford guys who flushed their PS fluid..

    The turkey baster can only remove most the fluid in the reservoir (not in the lines, pump, or cooler), so you will not have to worry about bleeding air from the system.

    Ford guys who flushed their PS fluid..

    The Turkey baster method doesn't cut it for me, so I flush my systems instead. I can't tell you exactly which hose is which on a new Stang, but our Ford trucks 'might' be similar. On our trucks, the return hose is the more easily accessible smaller rubber hose with the clamp on it that routes...

    Old oil & 50W replacement ?'s

    I dunno about that. In June of 2003, Exxon Mobil's tech advisor "Tom Olszewski" and Exxon's OEM/Motorcycle Market Advisor "Jim Rosa" talked somewhat openly about various products during an interview and one of the comparisons made was between Mobil's V-Twin 20W50 motorcycle oil and their 15W50...
