So i was using Torco 20/50 in mt bike since the dealer uses it and swears by it and he supplies me with it free. Money however is no object when it comes to my bike. That being a triumph 1700 cruiser called the thunderbird. The bike makes around 115 Lbs of torque at 2500 RPM as a stock 1700, but i'm running pipes and a custom map that makes quite a bit of difference. So id guess maybe 120-125 Lbs. However, they rate at the crank so actual rear wheel is probably more like 110@2500. So we're talking a lot of torque all the aw from 2500 or in other words throughout the powerband. It also weighs a lot at 740 wet.
I mentioned the specs because it will have a bearing on my theory. I tried M1 20/50 V-twin recently and noted a few changes which led me to this theory....
worse average MPG by about 3 MPG
very noticeable increase in power...accelerates quicker and pulls harder
runs hotter, IE: fan goes on much more
So i thought about it and it didn't make sense that the power increase would go along with the rest of it. If it's making more power that could only be due to oil that allowed for less friction. Yet if there's less friction then the MPG should have gone up and it should not be running hotter. So this is where this theory came in....the torco oil has a lot of moly. Even tho it's spec'd for JMSO the moly count is insane. It's something like 700 PPM (i think PPM is the measurement, right?)vs other oils which are all about 95% less.
So my theory is this...the torco allows for less friction and therfore cooler running and better MPG than the M1, and the reason for the better power with M1 is that with the Torco the moly caused the clutch to constantly slip to a slight degree making the bike accelerate slower and feel like less power. With the bike's weight and torque i could see that being more likely than with much lighter bikes with much less torque. I don't know how else to account for the fact M1 runs so much stronger yet also shows 2 changes that should not coexist with the power increase. I welcome any thoughts/theories because i'm trying to figure out what to do as far as oil. I always felt M1 was great, but when the bike runs hotter and gets worse MPG i gotta think the clutch is the reason due to the moly in torco. And if thats the case i want to find an oil that lets the bike run as strong as it does now but with the same MPG and temps that torco got me.
