Just wondered in anyone knows where in the UK i can pick up Brushes for chekpoints at a sensible price ??

The atlas brush is, what, twice as expensive as a regular brush and the long life is 3 times the money !!

I've been running the 4cell brush so far, as it's what comes in the motor and i assumed "best". I'll give the 6 CELL LONG LIFE INFINITY BRUSH a go but if burns up like the 4cell ones do i'm affraid i'll be going back to my Reedy and Trinity 19's

I'm guessing the infinity brush is like a lemans long life but i really do hope at the price, i can measure there life in weeks instead of races .........

Oh on a positive note i think the motor rocks, just can't afford to be installing new brushes every other run.........

Merciless, Microtech sell the Infinity for basically the same price as the XXX brush.

I'm getting 3 meetings to a set of brushes at the moment. My brother, who possibly doesn't push his motors as hard as mine, has just started running a Money motor. Will be interesting to see how much life he gets out of them.

the infinity brushes last a LONG time. i'm on my second set and have been running the motor since last november. there is no performance loss either in fact imho its even better with infinities... the second run after rebuilding seems to be the best but i don't rebuild until you notice it slowing. i've run multiple race days without rebuilding and been very competitive.

Oh, and what does everyone use to undo the brush nuts??? I fear m pliers will kill the anodising...

I just bought an open end wrench at local store. Much more as one now.

Finger tips. You shouldn't need a wrench on them at all. They aren't designed to be that tight. All of my motors have always had them finger-tight, from the factory and ever since.

Ditto...I guess they didn't read the sheet that came with?

well... read it today (found it in the back of the packet... doh!). Thing is, my positive nut is much tighter than the negative... i can undo one with fingertips, but not the other...
Still, now I've found some infinity brushes, shouldn't need to change it too often
Looking forward to running the motor this weekend, interested to see what will work better at Halifax, this or my trusty EA C2's

Well sometimes they seem to tighten up a little more on their own after you run the motor.

Just put a shop towel or something over the nut and loosen it. Definitely don't use the bare pliers or you'll damage the anodizing.

Much More sells a new wrench for the Checkpoint

I think the point is, you shouldn't need a wrench to remove and re-install the brush hood nuts.

Merciless

This is the only porblem i have with the checkpoint .........

It's not slow, infact it has great punch and ok top end but look at the state of it after just 2 runs !!

Moving over to the "Mega Money" long life brushes now to see if they improve things at all

Thats normal for a fast 19T motor now-a-days. They all look like that after one run. Just skim the com and re-run the brushes if you run Infinity brushes. They will last 15-25 runs. If you run Atlas replace them every 2 runs.

this does look very normal when using the ATLAS brush.... the Infinitey brush will last much longer but you'll still need to run a lathe across the comm when the motor slows. that varies on conditions of course
