I have mag. arms in my tra already,but would like to fine tune the shifting. I'm considering thunder shift arms or heel clicker kit. With the heel clickers does the clutch become out of balance? Also can anyone explain to me why the mag.arms have changed my clicker setting by 400 rpm per position, rather then the 200 rpm with stock arms? I've heard some good points with both kits, but at $500. cdn for each kit, I want to get the most for the $$$. thanks.

Im just gonna quickly cut n paste a rant I did a few times over on AMSNOW forums.

Rant goes like

Some guy says....
But the heelclickers ''fool'' the motor into thinking the clutch has heavy weights in low and mid-range but progressively get ''lighter'' as it shifts out to keep rpms and top-speeds up,, no other weight does that--adjustable or not.

Joe Says:
BAH!!!!
This is what bothers me of the description on how the hc's work. Fine yeah that is an ok analagy, but when you actually FINISH solving the problem and do a summation of both these ''Supposed'' c of g's on the hc's you get ONE c of g.

The C of G of the flyweight is that point you find on the flyweight if it were suspended in air it would be perfectly balance in all positions...regardless of the material concentric around the flyweight pin boss area.
Since this ''inventor'' of the hc has put the c of g's on the flyweight for all of us to see you can easily create a datum and measure these points distance from the datum and calculate the Final Solution.

Moving the composite details:
With the HH and TS flyweights you can load the holes that accept the composites with enough mass that the engine will act in the same manner as the hc's.
You load the heaviest mass towards the pin...[yet maintain the flyweight desired for peak rpm]...and you can make the engine run less than peak power and increase rpm to overrevving
or if you choose to throw all the composite mass towards the tip of the flyweight you can get an overrev condition which near the high end of the midrange the engine will pull down in rpm...but especially if there is a load like extreme bumps or powder snow...forget about the engine ever climbing back on the pipe.

...All of the composite style flyweight brands can do it. The one that I have had the lease effective results have been the Hooper Quick change and I believe it is because it has a Full Bodied tip. I want to take a heavy set of these flyweights and carve a mod tip so I would be able to emulate better like the TC and HH

Now last year guys have accused me of not touching these style of flyweights and I'll say I have. Many a times. I found guys who have purchased these products and reviewed their findings. I have borrowed these flyweights to test in other peoples sleds and the guys who loaned me the flyweights have given willingly.

We've done clutching weekends where up to a dozen sleds come to our lake to test. I'll work on up to 5 sleds at a time showing guys what to do with the flyweights to on purposely make these conditions arise.
After doing it they then race each other on the lake/rough trail flogging their sleds and come back and talk about what is happening in the seat of the pants. Then you look at the flyweight and have a fantastic mental picture of where to balance the composites for your riding style. Drivers give up nookie to come do this. LOL

I've done over and over again with OEM flyweights. You can take a heavier flyweight and carve the underside to the tip. Now the underside of the flyweight looks like 1/2 an arrowhead.
Trim the flyweight to the desired mass you need to run and find out what happens. You can take a stock flyweight of 52 grams to 58 grams and make it lose 1000 rpm in engagement from cutting this shape.

Wanna see a flyweight that looks like this in your hand?
1990 or newer Yamaha VK540 has this style of flyweight. It looks like an arrowhead with one side curved for the roller profile.
I've made 10's of Dozens of sets for sleds be-it trail or race.

All the brands are good when it comes to this feature...
...some brands are more reliable than others.

Look around and ask questions of what PROBLEMS guys have encountered with the flyweights. Everyone will tell you what they buy is great. Find the person who has had problems and you will learn something.
Anyone who tells you their problems encountered you can now weigh your desicion easier.
You don't wanna get stuck fixing something over and over again. Deterioration of performance to that point is frustrating as hell for the owner.

...Its your money.

MOTOR'N: I prefer the thunder arms,the heelclicker system changes the best clutch in the business into a comet type. It depends a lot on what you expect and what sled you have, I was able to set -up the thunder arms for my triple in very little time but a friend had the clicker system and he would get it good one day and the temp or snow changed and it was way off. These are just my opinions based on my experience with both. Dino

I'm not to crazy about carving up an excelent clutch, but if the HC's worked as good as as torquer claims. I might consider them. I'm leaning towards TS. Seems like they have something SKI-DOO engineers might have over looked. Or maybe their just playing safe. One more note. If SKI-DOO put their new 185hp. supercharged SEA-DOO motor into a sled, would you buy one? I know I would in a second. BEWARE RX-1s

I would, in a heartbeat!!!

I really love my RX-1 But that motor sounds SWEET!!! There is a big difference in horse power though, 180 vs 150. The doo would kick butt big time! Is the sea-doo motor a 4 stroke? I really like not having to put oil in each day out. Also, the no smoke filling my garage is a plus too! See ya On The Trail! Honk :hallo1:

The Red Ones Are Fastest!!

4-stroke, yes. It is a tripple cylinder, 1500cc supercharged, 185 advertised horsepower beast.
