Timing advance

[bondra131]

I have a 2014. I am going to put a b pipe on it and keep the CDI stock. My understanding is that MSD enhancers advance the timing a little. Would it be worth it for me to reposition the stator for a little advance or should I just leave it alone? I'm not sure how much of a difference this makes but if it's significant then I will do it since it's like a free upgrade. Please let me know someone who really knows

a stock cdi advances timing with rpm
a msd enhancer retards timing with rpm
so yes advance the stock stator w/stock cdi about 3/16 in
but when you put on a hi comp head get the enhancer

I advance mine by up to 3 deg with an Enhancer but all I ride is surf and I never do WOT runs for more than a few seconds at a time. I would not recommend any advance with an Enhancer if you do any WOT runs.

What are wot runs?

Wide Open Throttle.

What's wrong with running a high compression head with stock cdi? I plan on a head at some point too but only going to 180 compression. 35cc domes

Oh, I do that all the time haha even in the surf which is an occasion

Wide Open Throttle.

higher compression engines like the timing reduced at higher rpms

 

[bondra131]

Oh ok cool. So the msd enhancer actually retards the timing from stock?

Did you notice much of a difference with advancing?

It will run better, but you will also burn a piston sooner or later so leave ignition timing stock.

Leave it stock... hahaha

If your running an aftermarket pipe with stock CDI you are wasting your time unless you have modified the Rev limiter.

 

[Dartman]

he might just be ok if he uses the limited chamber and doesn't under prop it
stock cdi limiter is about 6900-6950 rpm
if he props it about 6700-6750 rpm will be fine for now

I will be running the 2014 stock impeller...

Pistons wear out sooner or later even in a 100% ski lol

How about modifying the oem cdi for a higher rev limit? Is that about the same as running msd?

The MSD has a different timing curve in addition to a higher rev limiter so there's more than one benefit to upgrading. That being said, advancing the static timing by 2-3 degrees and bumping the OEM rev limiter is a pretty cheap way to gain some power if you can't afford an A/M ignition to go with your pipe.
