Just playing, highly doubtful that most of us would be able to tell/feel the difference between a T/L and a TBM flywheel. There might be a very small (dyno needed) HP difference inherent to a lighter drive train but probably insignificant. Lighter drive train will aid in getting "on the pipe" and taking advantage of the "supercharge" effect designed into a given expansion chamber sooner, but more HP idk. Adding as much timing prior to detonation is going to increase the output of an engine. Youre limiting yourself with flat timing imo. Like I mentioned before , you are probably getting a hotter spark now that you ate pulling from the battery ( like Kawi SXR) instead of coil on stator. Basically all this can be achieved with a charging system is the proper components are chosen. Had the EPIC worked and had an aggressive curve installed you probably would have been happier and not had to deal with changing batteries. The analog T/L you have is definitely one of MSD's longer lasting products and should give trouble free opereration as long as it is maintained. Have a good time and once again I'm glad you have it on the water and are enjoying it. Edit: basically what I'm saying is had you just thrown a stock flywheel or a lightened stock flywheel you wouldve seen/ felt improvement and the EPIC can be programmed every 100 rpmI beleive giving you the ability to really tune ignition curve to your setup.

I had epic with stock flywheel and I also had tbm with stock cdi with no rev limit that worked nice. Maybe its in my head but even my mate from yamaha agreed total loss had more snap pull out the water than any of the combos we tried

I do agree tho that if I got tbm to work with epic that would be the ultimate setup as you never have to worry about changing batteries and tbm is only .7lbs heavier than the total loss flywheel

Not knowing the exact curves of EPIC or MSD I would guess youre getting more timing out of the MSD is where youre feeling/claiming the extra snap. A lot of people still love the MSD T/L for rec riding because of the spark energy coming from the battery but I'm pretty sure an aggressive timing curve in the EPIC with a lightened stock flywheel you'd be hard pressed to tell. Just an opinion mind you.
 
Lighter flywheel, MUCH hotter spark which cleans up tuning a bunch and an aggressive timing curve will all help. I've never ridden any aftermarket cdi/lightwwight flywheel combo that could mimic the power output of a properly set up MSD TL. We used to use Vilder fully programmable set ups with their proprietary total loss flywheel and it still wasn't as clean and hard hitting as a MSD TL.

Thanks Scottie. I've have T/L on Yami and agree that the spark is much hotter and helps. I was really speaking from a rec rider not racer perspective. I beleive that most of us would be very satisfied with a well written curve and lightened flywheel. Thats what I was getting at. And the whole "I got HP from a flywheel" thing.

Maybe you can look into a lightened crank if you didn't want to run the TL, not sure if it is the answer though. I think it snaps quicker, but once you let off it will be more abrupt. I would get it balanced to your pistons, not sure if they need the flywheel or not. I might try it when I am ready for crank rebuild from Crankworks. Just another option down the road.
Note: I don't have concrete results, because I've never tried it. I am sure a crank builder could point you in the right direction if you were to look into that option.

was just messing about wanted to see whats the longest the spark would jump to the tip before it goes for the side walls and this is it for me

i love the sound it makes jingle bells time

here you can see why the tbm didnt work the "curve" i was running for this test was a straight 21 deg till 8000rpm

you can see how its firing all over the place

i havent tested any other cdi with the flywheel so not sure what others dont work but i do know epic is one that doesnt its just to unpredictable

nope dont have a kawi to test sorry

Can you re-gap the plug to your normal gap and re-run the test so we can see what a more normal spark would look like?
Nice video by the way, deffinantly some amperage in that spark, thanks for the vid good stuff
