4° trigger wheel??

[Ferris Leets]

What is the difference from the standard trigger wheel?  Is it really neccesary to go to premium fuel with the 4° wheel.

There are 2 trigger wheels available. 4 & 6 degree wheels. I have a friend with a 6 deg in a tourer and he uses 87 octane (reg). We live at 1200' altitude. I've heard that higher altitudes need premium fuel. The 4 deg wheel was created for the interstate because the I/S ignition module (ICM) already has 2 degrees of advance in the midrange. Adding 6 more to that would be too much.

Good info.  So where does one get a 4° wheel and about how much $?

So if you are running a 6 degree on a 98 Standard already,  and you were to put an Interstate ECM on in replace of the stock standard ECM, would it be a bad thing or would it run like a bandit?

You might check out Diect Line Parts / I purchased my 6 degree wheel for about  $40.

You can also Google "Lamonster LAM-004"


Just a quick side note -
I purchased a 99 STD about 2 years ago.  It came fitted with Cobra 6X6 exhaust and a K&N.  I do not know if the carbs were re-jetted along with the other mods.  Enjoyed ridng last summer with no problems.  Last fall I installed a 6 degree wheel for better MPG and I saw a definitive improvemet.  I also shifted to higher octane fuel.  The old girl runs great and I rode all last winter without any issue, but this summer the pipe are starting to show blue.  I will be checking out the jets and may need to do some re-tuning to get things right.

Yes: This would be too much ignition advance. It might run on premium but preignition could be a problem. Burned pistons are expensive.

Looked at Diredt Line.  They only list the 6° wheel.

[Ferris Leets]

Nope,  All I get from that is that the Ect has more and faster advance, and the trigger wheels move the advance up.  Which I already knew.  Does not give any info about increased performance or whether it needs high test.  I see a note about Hp and Best mpg but are they saying it gets the best mpg at 34° advance?  Tha the advance goes back at about 2700 rpm? and then advances again at 5200?  I guess I don't understqnd the graph.

Found a 6 degree on Ebay Listed in category:
 
eBay Motors > Parts & Accessories > Motorcycle Parts > Asian > Accessories.  Added link but don't know if it will work.

Expires in about 5 hours - good luck.

My Bad - that is a 4 degree on eBay.

I'm going to tap out what may be one of my verbose responses, but will give you some history, and may shed some light on why this oft discussed topic gets a lot of heat, but little light.
Early on in the Valk production, 2 outfits made the wheels, LaMonster and Airlake. The 4° wheel was for the Goldwing, and the 6° wheel for the Valk. Then along came the Interstate. It had 2° more initial advance. Folks were putting the 6° wheel on the I/S with mixed success. Some would love them, and others would complain that there was too much pinging and preignition noise. In order to make the most customers happy, the answer was to use the 4° wheel on the I/S.
I had an I/S, and many more like me rode either an I/S or a STD/Tourer with an I/S ICM and used a 6° wheel with no problem at all, and lots of power, and a small bit of mileage increase.
With many chiming in, the outcome of all the responses was that those who ran their Valks at low RPM and rolled the throttle hard from 2500 or less would have preignition or pinging.
Those that ran at 3000 or above, or downshifted to accelerate hard, had no problems at all. This group also found no need to use anything more than regular gas.
Many are of the opinion that the ECT mod is the same or better than the wheel mod. I disagree. The ECT mod is only active to about 3600 RPM, where it reverts to normal timing. I want the advance up higher, and can only get that with a wheel.

What it comes down to is if you lug your Valk, the 6° wheel is probably not for you. If you spank that bad girl and make her howl, you will like the 6° wheel and get the most performance from the mod.
It has also been said that you lose some top end with the 6° wheel. That may be true. My outlook on it is that I use the acceleration a lot, and use top speed almost never. Mine with a 6° wheel would do 125 MPH on a GPS. Fast enough for a fat girl.
Hope that clears some of the variables in the decision-making process!  

I just looked and have a 6° LaMonster wheel. I'll sell it for the same price the E-Bay wheel goes for.

What is the difference from the standard trigger wheel?  Is it really neccesary to go to premium fuel with the 4° wheel.

I'd go with the Dana 3000 and be done with it.  Setting 5 will provide timing very near to a 6 degree wheel.  Setting 7 will provide the max timing at road speed and is good for about a 4 mpg increase in fuel economy.  Both require the use of higher octane fuel.  My 98 standard with K&N air filter likes the setting 7 for power.

Thanks Gary-I have the 6 and spank and use regular without pinging,blueing,and have healthy looking plug burn-don't give a sh.. about mileage or would not have bike with 6 carbs.If you lug your Valk and get 15k plus out of your tires,this mod is probably a waste of time and money.

What is the "ECT" mod. ?

[John U.]

The ECT mod is described in Shop Talk. Basicly it fools the engine control module into believing the bike is cold. I provides 10degress of advance unless you install a potentiometer. Then you can dial in how much advance you want. The advance returns to the basic advance curve at about 3400 rpm.
It's cheap and it works.

[Ferris Leets]

Looked at the ECT mod.  Seems like a good simple solution.  I may not do that right away but something to do after I have ridden this beast for awhile.
