767s are really good brushes for reedy mods. All you have to do is cut them for stand-up hoods and your good to go.

what i found is a drop of dextron transmission fluid for real cars makes the amperage go up. That's great but too much makes everything blackened. So with that I would say any lubricant would help if used sparringly. Also when breaking in brushes shoot a drop of rubbing alcohol, it seats the brushes and cleans the comm at the same time...

Wouldn't rubbing alcohol destroy the comm? It takes away any librication there is between brush and comm, not talking about lubes here but rather talking about the "natural" lubrication of the brushes (if there is any of course). But maybe is a good method, I will try it and see.
As for Tribo, it is really junk. I have done more tests today in my Fantom Dyno and both RPMs and Torque go down ALWAYS with Tribo.
I know Zubak makes good RPMs, never tested in the dyno though, I now have to try finishline's drops to see what happends

He said he was using them on a Kr which is laydown. And I've never been able to keep a set of 766's from burning up in a KR let alone a 767. I've never had good luck with that motor design anyways. The only time I have is putting the KR arm and endbell on a Ti can.

I've never used Tribo but I heard that it worked well on closed endbell motors but that's about as much as I know about the stuff.

I use Zubak Speed Juice and every time I've used it it has increased RPM.

Thumbs down comm drops - NOPE

do not like comm drops all together. save yourself the $8 and buy yourself a new carbide cutting bit. I find they just collect all the brush dust and make it in to sticky gunk that gumps up the bearing in the endbell and makes ya motor run like a dog.

I haven't had such problems with Zubak. I mainly use it for breaking in the brushes. Then I give the brushes a little wipe with paper towel to dry them. Then off we go to race.

I really rate the stuff for closed endbell racing, but you need to thoroughly clean the motor between races, and make sure to only apply 1 small drop to the comm, and make sure you turn the motor over a few times. It worked pretty well for me in Japan

Every time I dyno'd a motor (stock) with Tribo I gained a few watts at the lower amp steps (Turbo Dyno) and lost watts at the higher amp steps. Never noticed a difference on the track so now its just bushing lube... but its good bushing lube

The instruction says to clean the oil off the comm after each run. Do you also have to do this when the oil is used on the bushings?

Honestly guys...... I like tribo. I use the smallest possible amount directly on the com. It doesn't seem to change the motor's power in any way on the track, but the brushes seem to last a bit longer, and it wont eat the comm up as bad.

I did more test with Tribo, I just regret having bought this junk... It is like putting transmission oil on the comm, it gum up the comm, brushes and brush hoods and did not yield any performance, furthermore the motor run worst with it. All my motors showed less watts on the dyno when tested with Tribo.

I use this stuff exclusively and have never had one problem. I hate to say it but if your com is getting gummed up from using this stuff, you are probably doing something wrong. I have only seen Tribo gum up motors on 2 conditions:

1) when you use Tribo, you can only use Tribo on that motor until you rebuild it again. You cannot use breaking in drops and then run Tribo. You connot, for instance, run Zubak's for one pack and then try Tribo on the next without rebuilding the motor. Never mix com drops!

2) You should really clean the motor after each run or every other run. No need to tear it down but take the motor out of the car and spray it out with motor spray. While Tribo doesn't attract dirt, depending on how clean your track is, dirt will accumulate and gum up the come and brushes...but it's the dirt getting into the Tribo and not Tribo itself. Cleaning your motor after ever run or every other run will eleminate this.

When I practice, I run the same motor in my car for the entire day. During practice I do not rebuild the motor, reserate the bushes or anything. At the most I take the motor out of the car and spray it down with motor spray, let it dry and put it back in every third run or so. I normally so not even do this for practice and just leave the motor in the car and add several drops of Tribo before each run.
When checking the laptimes from pack to pack, without cleaning or touching the motor in any way, I am always faster during during my third battery through the motor than I was for my first run on the motor. After 6 runs on the same motor without a rebuid, just Tribo, my lap times are as fast as any throughout the day...all this and I usually run Putnam's Green shunt brushes on my motors (making it even harder on my com).

I've heard the same thing about how and when to use Tribo, but I have always noticed a performace decrease each and every time I used them. I tried them on stock, 19T, and sealed endbell with Trinity, Reedy, and Hurricane brushes, and they all gummed up the exact same way. And the dyno just confirms the on-track feel
