Savage 21 Tuning

[Benwahballz]

I posted a while back about tuning a Savage 21. I am just wondering if anyone has links, or tips on how to put it back to factory settings, ( I know its a certain number of turns from fully closed ) I just need to know how to adjust the Midrange and LSN (cause they touch). Which do I turn ALL the way in first? I believe it was the MSN first, turn that out to its appropriate setting. Then adjust the LSN to its factory, and finally the HSN.


After I tune it to factory. What order do I tune them in again, HSN, LSN??? (Idle first to make sure it RUNS first) I have a HPI filter on it ( just like a Motorsaver )

Your Savage 21 has three needles? An HSN. MSN and LSN then an Idle to adjust too?

As far as order, the general order should be as follows:
Set your 1-1.5 mm gap for idle. Test this to make sure when you brake it doesn't shut close.
HSN to tune for top speed
LSN to tune for acceleration/torque
then adjust your Idle again so you don't have such a high idle attributing to higher temps.
THE MSN I am not sure as I have yet to get an angine with this needle.

You should turn the MSN all the way in before you adjust the LSN. Then follow Jon's order.

Cool, I will have to try that out.
