2006 Harley Trike

Q:I have a 2006 Harley Trike the engine has a cam upgrade and increased to 96 cu in. I buy 92 octane premium gas. Only a few gallons at a time ( 100 to 150 mile rides) My bike has been pinging.
1. How much gas is in the lines from the storage tank pump to the nozzle?
Am I getting two gallons of the last dispensed grade and a quart of premium? I know this is dependent on hose diameter and length.
2. Are octane boosters worth buying and using?
3. What about Sea Foam tm it says to put in oil and gas?
OIL question.
My bike has always had Harley 10-40 Synthetic. I have a hard time finding natural. Easier with the engine turned off. I have been told to use a heaver oil in the transmission like 90 weight? As far as Harleys and Oil it seams everyone has an opinion. I guess I am asking for yours. You do a lot more bikes.
Thank You

A: If you search around your area, you should be able to find a gas station that has individual lines/nozzles for 92, or 93 octane fuel. That is your best bet, so that you can end up with a full tank of 92/93, and not a mix. There should really be no need for octane booster but you can always give it a try.

The weight of your transmission fluid has little to do with shifting into neutral. More often there is a problem with clutch adjustment, shifter pawl adjustment, or binding shift linkage.
As for fluids we have been very happy with Spectro.

    Your difficulty in finding neutral may be in the mount of primary oil you have in the primary case. If overfilled neutral may be a little difficult to find.

    Chevron is the only game in town were I live that has an individual hose for the 94 that’s all I use

    Guys it might be worth pointing out that the difference between viscosity recommendation for the Harley Trannys is that 20w-50 motor oil which can be used in the tranny has it viscosity measured at a different temperature then a 90 weight gear oil. Many folks don’t realize this and so it get confusing. In fact a 20w-50 motor oil is close cross over to a 75w-90 or 75w-110 gear oil when the viscosity is measured at the same temperature. My preference is AMSOIL 20w-50 for the motor and AMSOIL 75w-110 for the Trans.

    In 1998 my dealer switched my trans fluid to Bel-Ray semi synthetic 80-140 and it smoothed the trans right out. I’ve been using ever since in my 02 Road King. My lubes have been Amsoil in the engine, Harley 20/50 in the clutch and Bel-Ray in the trans. 80,000 and never a problem.

    I have a 2012 Tri-Glide. I have pinging. I live in Huachuca City AZ and am unable to get higher than 91 Octane. I’ve used booster, but don’t see much difference. There seems no scientific way to measure the proper amount of booster.

    My bike had been sitting for a yr,
    Got it started and let it idel when the oil cap blow off and shot oil all over.
    How do I know if my moters getting oil.

      Hi Bart, Most likely, oil sumped to the bottom of your crankcase during time in storage.
      If oil was added to your system, before starting; the system was overfull.
      You can plug in an oil pressure gauge, if you have any real concerns. Not very difficult to do. http://www.fixmyhog.com/post/tag/sump/

    I take my car to the gas station with a 5 gal. can I put 3 gal. in the car with 94 octane then fill the can that I use on the bike . I never have any problems this way

    I use Amsoil 20/50 and Redline in primary. I also use 75/90 in the gears. Surely 10/40 is too thin for an air cooled engine. As for pinging , I use 97 octane here and always rely on Archoil 6200 to reduce the temperature for better burn . There is bound to be oil in the crankcase : I might be wrong but surely lowering the temperature of combustion will give a more complete burn. I also use Archoil 9100 in the primary to lower the friction.

    Are there still fuel pumps with one filler hose and buttons to choose different octanes?
    Is it 1976 again?
