Re: DR750 max 4000 RPM

I took some time, but the issue is SOLVED! Arnold was right with R6. After changing to 15k rpm meter is working correctly. Why? My opinion is that: I am running DR750 (SR41) which has different ignition system vs DR800 (SR43). Differences are CDI, number of ignition coils on the stator (SR41 has 1, ...

Re: DR750 max 4000 RPM

Arnold,

you are right. RPM readings are not cut exactly at 4000, it goes a bit up and than very fast to 0.
Something like this:

I will arrange oscilloscope and do the recommended measurements.
Thanks for help!

It was hard to find new motor. After rebuild I know what is inside. It should be all right now.
In my opinion F2R is also a good option. I will use this year, so I can do summary at the end of the year.
I will create new thread with my issues. I did some test lately and wanted to include them.
cheers!
