Hi my bike has a ping on the very bottom end when going very slow under hard load.Anything over 10km per/hour it is fine this happens only in high range and I can throttle throught the ping.Mods to my bike are HMF pipe with quiet core,HMF optimizer 3/2.5/3 setting,K&N filter,DYNATEK cdi,clutch mod 4 450 weights and 27" tires and WISECO 11:1 piston just done about 400km's ago. My question is I thought (pretty sure I know) I read somewhere that timing can be adjusted thought the pod up to +or- 8 degrees??I run 91 octane fuel.I ran 87 octane with the stock piston and all the other mods with no issues.I have not tried an octane booster as of yet.I would rather pull a degree or 2 out of the motor threw the pod/ecu.Any opinions would great THANK YOU
With 11:1 you shouldnt need any more octane than 91. Though its very intertersting this timing advance. Too bad you didnt have a VDI. Could adjust through that.
Nice Family Avatar BTW

Grizzly 700 setting info Offset at ignition.This function corrects the general differences in the ignition timing requirements caused by different fuels etc. Adjustment Transfer to adjustment mode. While holding down the "RESET" and "SELECT" on the meter, turn the main switch (the engine stop switch will not function). "Co" appears in the left of the display area for the time and distance. 1. Press the "SELECT" button. The display changes to "dIAG" 2. Press both the "SELECT" and "RESET" buttons at the same time."d01: XX" appears the displays area. 3. Press the "RESET" button 4 times.Check that "d60: 00" is displayed 4. In this state, operate the engine stop switch "OFF" ? "ON". "d60: 02" is displayed.This indicates that the ignition timing is 2 degrees too early in relation the to standard state. Repetition of "OFF" ? "ON" on the engine stop switch repeats the following sequential display, starting from "d60: 00" "d60: 02" (2 degrees advance) "d60: 04" (4 degrees advance) "d60: 06" (6 degrees advance) "d60: 86" (6 degrees retard) "d60: 84" (4 degrees retard) "d60: 82" (2 degrees retard) "d60: 00" (standard ignition timing) 5. When selection is finished, turn off the main switch to complete the procedure.
Hmm, I wonder how much you could advance timing by running 93 octane.
On my car the general rule was that you could add 1* of timing or 1 lb. of boost for every octane point. If this is similar then you could add 6* timing if you switched from 87 to 93...wonder what kind of gains you'd see?
This is the first I've heard of this btw, good info.
You will gain next to nothing. VDI did this with dual maps for the KQ. With stock compression of 10:1, the KQ can run on 87 octane just fine. But VDI included a map for 91 octane. So you had the choice of 87 or 91, ontop of pipe or no pipe etc etc etc.
The 91 octane map with advanced timings (to account for longer burn times of higher octane fuel). Gave a total gain of around 1/8th of a HP on identical machines with pipe and filter. So whats 1/8th on 40ish?

At least it wasnt on the king. And infact Quad magazine (think it was them. Might have been dirt wheels) a few months back did a test on the myth of octane vs HP. And it turns out you wanna run as low as you can without ping or knock. As too much octane robs HP. Since it takes longer to burn, and its not burning at ideal compression. So run only what the motor wants. Nothing more.

I have a grizzly 700FI 2009. I have a problen with the timing. I setting the ignition she have d60 00 she have a yoshimura pipe. the problen is when i run a slow speed she has a small explosion in the throttle body. I think it is out of time....... you to be the problem?
