If stockers weigh 61X flywheel 3.610 lb and 62T 3.7436 lb

and you can safely take off 0.5 lbs of them for $65 or so.

you have 3.1 or 3.2 lbs for $65 vs 2lbs for over $600?

I know 1.1lbs is alot when its spinning 8000rpms, but man thats pretty expensive performance!

Agreed 100%
Not saying I am getting one really have no need for one with my riding skills.


Look at the cost of TL.......Wow!

There you go right there. Get what ever prop is lighter (can't remember if it is skat or solas) and there the extra 1lb +-
 
Ive ran every flywheel made for the Kawasaki twin. (Almost everyone)

TBM - First version. too light and it cracked..It really was light and hit hard but it wasn't as good as others in the chop ( lost momentum)

TBM - Second version. heavier and just fine for racing not as hard hitting as the first version and not as good as the JSU overall

RAD - charging - Heavy compared to Tims (not much difference over #5)

GroupK - lightened - not much lightened noticed a little

OEM home done Magents removed and lightened - excellent

MSD Total Loss - Excellent - not as good as others in the chop

Vilder Charging - best of everything - mass centered closer to crank and charging or total loss with advent ignition
Warning FIRST VERSION - with 5-holes cracks on modified motors..its lighter and hits harder but Cracks

Vilder total loss - same as above but harder hitting and the right energy for the chop

JSU/J-lines - Excellent and best all around - no issues or problems just about right weight for most racing conditions with 850cc range mod motors

Issues: Starting rings came off the MSD and the RAD had to peen them mutliple times.

Wouldn't build another total loss motor without the JSU flywheel if I was racing. Rough water riding..oem modified....jumping...MSD or JSU

Never have ridden in the salt with my skis so dont know on that item
my guess would be Vilder because its anodized aluminum and zinc plated gear/hub cap

The original post is Yamaha my comments are still valid except for the total loss using ADVENT....you have to run a Kawasaki style (or 760/80066e) electronics in an SJ. It can be done very simply by running Kawasaki stuff or 66e combined with Kawasaki Advent

MTRHEAD, great review!! A few years back I got to ask CJ Vilder about why his flywheel had no holes. He told me to prevent crack probogation areas and the mass was set up for keeping rpms while going through the chop. I guess its more than just cutting a round piece of aluminum with a ring gear.

TL loss flywheel 1LB 12oz.

TBM 2.0 LBS

So why have the hassle of TL? IMO

Because the advantage of MSD TL isn't just in the weight. You don't have the EM drag on the magnets, and you have nice programmability and full energy spark from the bottom on.

Can someone explain to me just what the hassle is with popping the hood and attaching two wires to the battery to charge? :dunno:

I dunno Matt, it is a pretty big ask....I mean putting those two clamps on the battery when you're cleaning the engine bay out is quite the bitch...

I get 3 tanks out of my battery before I have to recharge it...Deka AGM.

Now that I have run total loss, I'll never go back. I've tried every ignition out there, and this by far kills them. I like the way the starting system is seperate, and fault finding (if it's needed) is a breeze.

Anyone that says MSD's are unreliable is either a hack, or doesn't understand how to set them up properly.

Total loss - $1200
TBM Flywheel + Your choice of any of the dodgy aftermarket 701 CDI's - $1000

Come to think of it, given the lack of decent reiable charging cdi's available at the moment, I would go as far as saying that the total loss is the most reliable ignition out there (apart from stock).

or how you will feel when your 600 dollar flywheel gets taken out by the bendix. ewwww. pickups and tl flywheel would still be cheaper to replace.

i am running one of these flywheels and i will say that they are awsome i have stuffed with tl and i agree that tl if set up right from the start you will have a great time with it but for a lot of people that ride salt water all the time tl is no good not tl fault imo people just dont understand how to care for there stuff properly
they do work with all ignitions now including wax inferno and advent but you have to specify what ignition you are running so that you get the right magnet style
as far as bendix taking out the flywheel i had that problem at christmas and i am working with tim at the moment to try and fix this as far as customer suport tim is great to deal with my bendix blew and took the flywheel with it not tims problem but he is doing his best to rectify it
imo i ride 100% surf/salt my dual bilge runs 90%of the time i ride for my peice of mind i want a charging system and i would say the botom end hit my ski has aint far off what it would have with total loss and the same ignition curve

I love my dual digital MSD TL... I was a charging aluminum flywheel enhancer boyee for a long time!!! :cheer:

J/k, seriously...
I ride flatwater 99.9% of the time and I was looking for the most bang for the buck ignition that my budget would allow. I waited, searched and found a used TL that was 3 years old but only was used for half of a race season and had been sitting on a shelf ever since..

I paid $500 for it and it was mounted on a alum board ready to go. I just had to come up with a starter solenoid. It came with 2 new extra coils and 2 new pick ups. I ran it all last summer(5 months solid) with no probs whatsoever and can get 3 tanks through too before it needs charged. I use a Lynn Vick Power source battery. It's been very reliable, time will tell..but i did set it up right and take care to dry out everything. My brain box even had some salt water corrosion on it. He said he ran it in some surf races with no probs. But that was racing not freeriding.. even though it's still brutal charging WFO jumping through the waves,etc.

I think like someone mentioned earlier.. If they are set up correctly and precautions taken, like the wires from the pickup sealed down to the stator and also the wires coming out of the coils sealed up and using die electric grease on connections and good grounds, etc. they can be real reliable.

If a bendix comes apart or something else happens, it could trash your flywheel. If you have a alum charging f/w its going to cost 3-400 bucks to replace with just a good used one. You can find used mint MSD flywheels going for $50-100.. Not to mention the stator could be trahsed too. Thats expensive to repair/replace vs. 1 $50 MSD pickup coil..

You can run a bigger gap with the huge spark it makes and when you ingest big water, the big spark starts it right up with a couple plugs of the primer. Where I know OEM spark takes WAY longer to get it going, wearing down your starter, bendix, battery, etc...

Not to mention the programmable timing, thats a given... Being able to run a REAL aggressive advance on bottom/mid and then taper it on top for pump gas is a real bonus if you want or WFO timing for full race gas/ported setups. Whatever you want!

I was expecting more bang for my buck when i bought my first enhancer. At the time I already had a alum charging f/w and a OEM CDI w/ Pro-tec rev limiter mod. I was just expecting more, thats all. With this set up its the alum charging f/w that kicks ass. The "enchancer" is just a little bonus...

The enhancer is a puss on the timing curve if you ask me. They could of made it way better, BUT they made it just a hair better than stock, just to say its better and then the masses would buy it because it says MSD on it and it has a more aggressive timing curve.. I guess maybe it has more spark too, but I know its nothing like the TL spark from those single big ass towers!

I always take the hood off after i ride and get the water out of the hull and have a fan that I use to dry everything out overnight. Plus its alway hot and dry in Havasu...:crazy: so everything drys out real quick. Prolly good for the old MSD TL.

I too will never go back to anything else on my main flatwater lake ski.

If I lived by the ocean and rode surf mostly I would have enchancer and alum charging flywheel on my main ski.

My square surf boat/guest ski has OEM ignition..

Anyways, my .02 worth of thoughts and experiences with ignitions. I'm sorry, I didnt mean to hijack this thead too. :smile:

I would use a TL system in a heart beat if I could find a used one for cheap. I already have the battery maintainer and wiring I just need the TL setup to plug it into.

I don't see how it would be a problem. Just pull your hood off and hang it up lay your gloves and shoes out to dry and plug in the charger done until the next ride.

hood?

what is this part of the ski that comes off?

have you seen inside my hull?

the fuel spills generally keep the mold and fungi at bay.

Were not talkin 650's that we leave down on the lake dock all year and never take the hood off and grow that funky black fungi all over inside the hull...:trink26::friday::icon16:
