So, if you wanted to take out the MSD, you would have to get a whole new Electrical box/CDI?
What happens if it does go bad? Does it damage anything else if it goes?

Sorry for all the questions..

No just a replacement of the cdi

what LBE running a not stock motor? thats unheard of!

Listen wiseass, I've been building this bigbore for a while and I'm ready to throw it out the window and go with a stocker.

But really, it will be my first non-stock motor build, I think it will go good in the B1.

If you use the "Enhancer", also use the MSD coil as a set. My luck with the
enhancer and a stock coil :frown: . The stock coil might-will go bad quickly.Like maybe in a weekend? But it is hard to trace for a newbie. It will idle on the trailer and seem to rev up, but, in the water it will break up real bad. Get ready to chase your tail. Been there...Done that. $$$$$.

Sure it just wasnt time for your coil to go? I rode 6 months on a MSD with stock coil before mine finally went bad but it was from a 97

ive always ran them with stock coils, in fact, ive read several times that the MSD coils are junk.

I have let mine arc against the engine, and fire ungrounded too, in my opinion they are plenty robust.

There's allways the exception...My 2nd "stock coil" was brand new, from a new
wetjet motor electrial box, maybe tested 5 minutes. Lasted only 2 days. Fachizzle. It would run up to about 1/2 throttle and break up. pop..pop..pop..:aargh4:


I hate working on junk.

well i had problems with the msd enhancer right from the get go, i pull it from the box, hooked it up and my ski would turn over but no fire, it had spark, and fuel, but it was faulty right from the time i pulled it from the box, i plugged my stock one back in and my ski fired right up, is this common for enahcers to be faulty?

I have run mine for 5+ years without problems and I ride in salt water. I have heard that they fail when there is a bad ground. I dunno if this is true but I buy dielectric greae by the bucket. It goes on all my electrical parts/connections. I'm currently rebuilding a motor and thought bout selling the enhancer while it is working, prolly get at least $150 for it, and pick up a stocker for $40-50 and modify it. But I will prolly just keep running it.

I have a question that might go in this thread: If I run the enhanser on my Yami 760, should I still advance the static timing on the stator? I was gonna run 4 deg advanced on the stator. Bad idea in addition to the enhanser?

ive never tried it on a 760, but I run a 2-3mm static advance on the stator with MSD and no problems.....


stock motors rule!

I am doing the same, I have had my Enhancer for nearly 9 years now and have since switched back to a stock coil with replaced wires. The coil, stator, & flywheel is from my old 94 SJ and all works well. The CDI does not care what engine is is on 701, 760, Lamey 800, etc. You can not run the stock 760 stator as it is for the digital CDI that is different from the analog systems of the 61x and 62t style engines. The 61x flywheel is a little lighter, I would run this setup with the flywheel further lightened by LPW.

If you are thinking about using an Enhancer, you really need to know what you are planning on using your ski for. If you have a stock engine (well, stock compression, or raised up to around 180ish) you'll be able to use the Enhancer for race/freestyle.

Anything that involves more compression is going to spell disaster. The reason being that the Enhancer raises the entire curve, and just like stock, doesn't really taper off enough if the upper end of the rpm's. More compression, and advance equals more heat. In this case you need to go easy on WOT runs.

Statically advancing the stator is great for bottom/mid, but with extra compression is destined for failure. Just today my mate took the corner off his rear piston running 180psi with an Enhancer and r&d dry pipe.

Don't get me wrong though, when they work, they're nice, but I would spring for a programmable digital cdi anyday

****** yeah!

I still think the 10 sec WOT test stuff is hilarious!

Hey D,

Yeah, the old 10 second WOT test was a bit inaccurate! Turns out it took 11 seconds to toast the engine...On a brighter note, sweet porting and total loss just made me VERY happy!

An enhancer will run in most flatwater freestyle boats as they never get held on for more than ten seconds.

have you ever seen this?

http://www.msdpowersports.com/pwc_enhancers.html

according to the manufacturer it has a vastly different curve than the stock CDI, but it does taper at the upper RPMS identically to stock.

In my opinion, your buddy's dry pipe was just a much a contributing factor to melting a piston as the ignition.

I'm not doubting that, but if he was using a decent ignition, it wouldn't have been a problem. Dry pipes are, after all, designed to get the very most out of your engine as far rpm's go, and therefore should be able to hold WOT forever without failing if the right ignition curve is dialled in.
