SRX 700 what rpm?? with aftermarket tripple pipes

8500 rpm is not the issue with our CDI's. I have posted this before, and it should be make a sticky, but here are the 2001 SRX timing specs again:

7750 rpm - 18 degrees
8000 rpm - 13.5 degrees
8250 rpm - 10 degrees
8500 rpm - 9 degrees
8750 rpm - 8 degrees
9000 rpm - 4 degrees
9250 rpm - 0 degrees

You can spin the SRX motors anywhere under 9000 on the stock CDI, and still maintain decent timing. You can always bump up that timing slighly using an offset keyway, but it is not a good idea to do that when trail riding at lower rpm intervals. After that, it falls pretty hard.


ryan , i am running aaens on my 600 trail improved , this year , spoke to aaen and he recomends i spin them @ 8750....question:

8df box @ 8750rpm = 8 degrees timing

or

8ch box @ 8750 = 18 degrees timing valves open or none
 

call justin @ full power performance. he was part of the bender development team for the srx pipes. he will have the answer. 716 699 6299.

I run mine at 8450 RPM, That's where I make the most power with my Power In.c pipes and case/Cyl porting.

18 degrees is far too much timing for our distance. I tried running 11 degrees on my 780 for a few runs, and it didn't like it. I went slower every time, and it felt quite flat. The next time I head to the dyno with the trail sled, I will play with the timing a bit more.

Also, it will produce no low or mid range power with the valves locked open. There are ways around that though :) You can run an RPM window switch to open the valves at a certain, settable rpm.
 
So glad I found this thread. Great timing info!!! Had a pull through on a stock '01 700 so I'm in the middle of a PV repair job, but when I get done I want to set my clutch up better than it is.

It has a thunder shift kit; easy to adjust, and I have it so it winds up to 9,000 and stays there or creeps to 9100 on hard packed or the lake, but apparently I'd be better off at 8400 to 8500 instead.

My question is this, I've also heard the tach on the dash isn't all that accurate and I don't have any other means of determining RPM, so... How far off is it typically and in what direction?
