Was looking for some honest input. I want to advance my timing and don't want to go the bypass sensor route. I was thinking about the I/S Cdi box with a 4 degree wheel. After reading was also considering the dyna box. So does anyone know how much more HP & torque this will gain on either one of these set ups.
Mods so far are a K&N filter and the exhaust 18" glasspacks with the 4" truck stacks. Thanks

I have the I/S ICM and I/S carb springs on a Tourer (no trigger wheel). I noticed a little improvement. As I ride in all altitudes, I don't want to use the 4 deg wheel too. At higher altitudes, you'd need premium fuel. Using DynaJet needles and adjusting the pilot screws will give you a bit more too.

A trigger wheel is the best bet!
Other more expensive modifications may yield some results but at the same time are not guaranteed to make you happy.
Usually there is a trade off in reliability when you add in aftermarket performance related accessories.
Not only that, but sometimes there is a reduction in performance whereas your seat dyno will be telling you differently, and how great an "improvement" you have made. The psychology of self induced myopia.

I also have a 99 Tourer, also glasspacks and truck stacks. I recently removed the K & N and went back to the stock filter. I have been using the 6 degree trigger wheel for about ten years, so I don't have a "fresh" perspective. I used to use premium fuel, but have been on regular the last four years both in Florida as well as North Carolina, and have not noticed any detonation. I think I get marginally better mileage than other Valks I have ridden with that have the stock timing.
I think the Interstate ignitor with a 4 degree wheel is the way to go in terms of both reliability and horsepower gains, but I have been reluctant to spend $150 on a used Interstate ignitor when mine is working fine. I had a new Valk owner comment to me the other day that his trigger wheel was going to give him an extra 20 horses and five MPG. I told him he was going to be disappointed...

I have a 99 Tourer. I put the 6 degree trigger wheel in last year. I run premium which is 93 octane here in Colorado. It seems to be snappier, didn't notice a huge difference in performance. However I consistantly get better than 40mpg riding solo. First rides this season so far have been commuting to work, 21 miles one way, 2,500 feet altitude change. First tank: 185.4 miles, 4.04 gallons.
45.89 mpg. Note: not overdoing it on the throttle.

I am running the I/S ICM, I/S carb springs and the ECT mod. The advantages I've found are that you can dial in how much advance you want (approximately) and of course the price. Lastly, you don't run the risk of screwing up the trigger wheel install.
I have a 4 degree trigger wheel, never installed becuase I'm happy with my current setup.
The Dyna 3000 will give you many more options to play with but take your stock ICM with you, you may need it to get home.

So...what would be the advantage of adding the 4 degree wheel AND the ECT mod? Performance and HP are nice, but I'm more interrested in mileage.

Go with one or the other! Both is not the recommended procedure. The trigger wheel is probably best for you. It's like do it and forget about it. No fuss, no muss! *** |
