I have never used total loss and recently just bought a used MSD 4270, older system, Everything is there and it was on a running ski so I was told. It is for kawi, 650, 750 800.

It is all still wired up, pretty much but I would still like to find some instructions and maybe some input from guys who have ran these systems, tips, info, timing, etc.

I have searched pretty much every thread I could find but couldnt find any that was straight forward, most I found were people with problems on theyre system,

It has 1 trigger and 2 magnets on flywheel, I can post up pics of the system if needed.

I dont want my first experience with total loss to be a bad experience. When do I turn the system on? when do I turn it off? How do I set it up for straight bottom end power? any tips, tricks, helpfull info at all will be greatly apreciated.
Thanks

i was in the same boat a couple of months ago.i installed my 4270 in my 760 sn.which rpm modules do you have?if you want to know how to get the most bottom end,just set the initial advance at 25-26 degrees.some people will tell you 30 degrees,but thats too much because the ski will be hard to start in the water.just set the piston closest to the flywheel at the very very top (tdc).then install your trigger plate and flywheel and make a mark on the crank case to indicate tdc. and hook everything up to 12v.THE DIMPLES ON THE FLYWHEEL REPRESENT 5 DEGREES OF ADVANCE.turn the flywheel by hand and watch for the led light to come on on the msd brain.as the magnet passes over the trigger,the light should illuminate.when the light comes on,the spark plug will fire.u want to adjust the trigger plate by the slotted holes to get the light to come on when the flywheel is 5 dimples before the timing mark you made.(which would be 25degrees advanced.) hope this helps,its very simple once u get into it.

Yea, I tried the forums but it wont let me post anything, I called MSD and the guy said he would email them to me but still havent recieved anything yet.. Thanks MSD!!

jetpilot36... Thank you for taking the time, what you say makes total sense..

Here are the modules that I have with mine,

RETARD START POINT- LOW RPM MODULE... 4000

RETARD RATE.... 2*/ 1000

HIGH SPEED LIMIT... 9000

That sounds like a gnarly curve.
To plot it out, figure that your timing from 0-4000rpm will be your static timing.
From 4000-9000, it will decay 2 degrees every 1000rpm, so at 9000rpm it will be at static minus 10 degrees.

if you only have a 2degree per 1000rpm retard rate,then i believe if you set it up for 25degrees initial advance,the retard rate would not be enough for wide open throttle runs.i mean you would be running very hot by not retarding your timing enough at high rpms.especially if you're running a 9k rev limiter.wow!thats a high limiter.seems like it was on a raceboat maybe with that setup.it will be fine if you dont advance the timing too much initially.i would try maybe 20 degrees or 18.that way on the top end you're not running very much timing at high rpms.JUST A SUGGESTION.

HERES what i got 27 degrees static
pull timing at 5000
with a 8500 limiter and its a freaking arm jerker.too bad its on a sn~!!

Yea, It was on a old race runabout xir. The ski this setup is going in will not be a rec ride ski, so there will be no high speed runs, just setting it up for flat water freestyle and want it to hit really hard off the bottom.

Thanks for the helpfull info guys. If you think of anything else I should know just post it up.
