Yamaha R1 Starter Problems - Again! Won't start when hot

For the last couple of months, the r1 isn't starting the way it supposed to. The engine would turn over like twice and it would appear that the battery is dead. Being a bit lazy and looking for the easy fix, I thought it was the solenoid. Ordered that off ebay, installed it...same issue. Then I said, it's got to be the battery...ordered the battery, installed it....., nope, that wasn't it either.

A couple of weekends ago, I took out the R1 starter again, and if you've been following my previous blog posts, you know what a pain in the ass it is. Anyway. It appeared to be the starter brushes. Since I didn't have them on hand, I used some brushes from a big disc grinder that I have and filed them off to shape. I didn't think that it would be an issue, but the copper wire on those brushed are half the thickness of the original ones. Result: the R1 starts alright, however, not when the engine is warm. Cold start, no issue, hot start, just the same like before: woo-woo-woo and dead. So, I got it half fixed... Now I am on the look out for the brush kit for the R1 on ebay, but it's like $75... I think I will still try with other brushed from an electrical supply store, just try and find thicker copper wire brushes.

  3. Had the same issue and it was in fact the starter. Any easy way to tell is when you try to start it and it won't, touch the positive wire from the battery, see if it's getting hot, if it is, then it's definitely the starter drawing too much current as it tries to spin the engine because it is in fact faulty! And for whatever reason the heat amplifies the issue, and that's why it doesn't start when hot

  7. 2010 R1 does the same thing. Has to be less than 175 degrees before it will start again.
