Hey did you guys use any type of sealant on the SOHN gasket?

No, but I don't see it as a bad thing if you want to add silicon gasket sealant. Just keep in mind in as tight of an area as it is to work in there, which is very tight, you're gonna have it messy and plastered all over the place.

Yeah good point may be I'll out some black RTV on before to hold the gasket in place.

Grey huh? I just happened by advanced autoparts and found what I think to be the perfect reservoir for the premix (yes even though I had already bought one online).

But this one will allow me to keep the battery where it is and not modify the factory windshield washer fluid bottle.

Mine is done, Pics to follow tomorrow!

Oh, and as I was trying to explain to others what it did I found this quote.

But, 2-stroke must burn off without leaving any plug-fouling or detonation-initiating deposits. The detergent and anti-wear additives used in 4-stroke oil leave hard white ash behind when they burn, just what you do not need in a 2-stroke. So 2-stroke oils use low-ash detergents and dispersant s, and the better types use ester synthetics to act as anti-wear compounds.

So What two stroke oil are you going to run now? I think continued pre mixing with Lucas Top cylinder Lube is a good idea until you get your tune to inject more oil.

I used some 2-stroke oil from a local motorcycle shop then switch to Idemitsu of late since it's used in pre-mixing, which is exactly the same thing we're doing with the Sohn Adapter in regards to reaching the seals.

I used the rest of the fully synthetic Pennzoil I had and from now on I am going to use Amsoil Saber pro. I didn't get a chance to mark the bottle to see how much is being used due to the rain but i will tomorrow. Gotta make sure it works, haha!

Are you saying premixing in the fuel is the same as the SOHN?

No, I'm saying the oil that is used as premix whether rotary specialized or 2-stroke oil is the same oil you want to apply to the Sohn adapter. I should of worded it better; they're not exactly the same but the main benefit of doing either or is the same. Sohn adapter has the benefit of not mixing the engine oil into the combustion chamber where as premixing alone lubes the injectors and seals more effectively.

I'm looking into later on getting an AP to bump up the oil injection rate.

Ah, hah. Okay, I misunderstood. Yeah I am looking at getting an AP too when I stop spending money on other crap. Right now I have some Pennzoil marine to use up and then I'll get some good stuff. And I don't have a cat so I'm concerned about using TWC3.

Does anyone worry about the temperature of the premix? It rarely gets cold her but this morning it was in the low 40's and it got me thinking of what effect cold premix had. I mean I know how hot it is in the combustion chamber but does teh premix temperature going in have any effect on anything?

It's a legitimate question, but it will ultimately require input from someone's experience with cold weather.

The question is weather the oil can be sucked into the pump when it is very viscous. Oil suction depends on a spring pushing on a piston to create a vacuum over a very short period of time. If that spring is not strong enough, or the oil is too viscous to flow sufficiently under vacuum pressure, then a full charge of oil will not be drawn in.

Once the oil is in the pump, the outlet stroke is positive. The oil will be forced out no matter what (or else break something).

With regard to your concern about injection temperatures, don't worry about it. It takes a relatively long time for the oil to make it from the pump to the injection nozzle. This coupled with the fact that the tiny tubes are not insulated means that the oil temperature will reach the ambient temperature of the surrounding engine bay, regardless of the temperature it had on the start of its journey.

Yeah, I was trying to find a diagram to see what route it takes through the rotor housing to get to the oil injection nozzles to see if it would be heated by the time it gets there.

And there is also the time it spends in the pump itself which will be hot because to the metal to metal contact with the engine. Again, the question is whether the oil will get into the pump in the first place under extreme cold weather conditions.

Yeah good point. It does not get too cold here but maybe I should put some premix in the fridge to see how it flows when cold.

Yeah so it's probably like five times thicker even at 100 degrees F. Wow. Funny though that the synthetic Pennzoil Marine I'm using has a much better viscosity at 100C than the Amsoil Racing stuff. saber pro has a better viscosity at 100C than my Pennzoil does the viscosity index is not much better so..............Have to look up Idemitsu.

Okay so the Idemitsu's number are actually lower than the Pennzoil and it is pretty thick at 40C. The idemitsu's flash point is also 26+ degrees higher as well although I assume that is not really and issue in a premix. Glad I looked that up.
