Can worn starter brushes cause slow turn over of the motor, anyone source starter brushes?

[OlderHuskyRider]

I've got the right side exhaust valve to the tightest I could get it, and no help.

Also, the ADC is working perfectly, I rotated the engine until I saw the ADC lobe hit the ear on the rocker arm, I stopped, and the ADC ring was jammed up perfectly, opening the exhaust valve.

A few months ago, my friend bought and sold a 2007 TE250, and I couldn't believe how fast that bike turned over with the e-start.

My bike turns over VERY slowly, and I already bought a new battery, even hooked the 2 batteries inline as a boost, no help.

Also, today I noticed that the e-start, when I can actually get it to overcome the compression stroke, will NOT even actually start the bike even though it is turning the bike over. I am thinking, it is not even turning the bike over fast enough to start it AT ALL, because I can pull the kicker out and it will start instantly.

Has anyone ever had worn starter brushes cause slow turnover, this problem has advanced slowly over many months. Bike has almost 17,000 miles on it and ALOT of use of the e-start.

i had the same problem with my 449,grim starting. try tapping the starter motor while hitting the start button. if she fires up its likely to be worn brushes. i pulled my motor off cleaned it and fitted a new set off brushes,starts great now. i paid about £30 for a new brush kit in the uk. if you are stuck i can try and source brushes for you.

forgot to mention at first i thought it was my battery and tried others, but then tried the starter motor tap whilst pushing the starter motor button lol.

Worn brushes will also burn and pit the commutator causing further performance loss, especially when max torque is needed to get it turning. Get some fresh brushes and fine sand paper ~400 grit. Touch the sandpaper to the comm while turning the motor by hand to get the pits out or at least reduced. Don't want to take too much material off. Then hit it with Brasso until it's nice and shiny. That will make it like new and won't cause excessive wear on the new brushes.

I didn't see this thread but I suggested brushes in your other thread. Tight bushings/bearings are important too.
You can check to see if any of the windings are open or go to ground.
