When I pull hard, full throttle in 3rd the bike will run strong all the way to around 7500 RPM, and than star cutting, like the rev limiter kicks off. I put the coils on a relay, and getting about 13v to the coils. Any ideas for where to look for this problem?
Thanks,
Eyal

That is what my 2nd gear issue feels like, a rev limiter around 7500.
The glass is not half full, it was engineered with a 2X safety factor.

As I recall, the FJ's sold in the Japanese Domestic Market were (among other things) RPM limited to 7500...
Do you by chance, have a JDM model?
1) Free Owners Manual download: https://tinyurl.com/fmsz7hk9
2) Don't store your FJ with E10 fuel https://tinyurl.com/3cjrfct5
3) Replace your old stock rubber brake lines.
4) Important items for the '84-87 FJ's:

Did the problem start after you did the relay mod?  Or did you do the relay mod because of the issue? 

How does 2nd gear behave?  4th gear?
