Rode with a friend other day. He has a 98 Valk Std. with 15k miles. I have 01 I/S. with 85k miles. His bike revs up quicker. I have the 6 deg. trigger wheel, glasspack mod. and more miles. Any idea on what the dif. might be,why his revs up quicker. Do I need to go bk. with the stock TW or sync. the carbs. ? Thought mine was the powerhouse til sit on his.

Its been awhile since trigger wheels were hot for discussion but I think I remember its not good for the IS to have a 6° one. Since the engine is already advanced over the standard and tourer. I believe the 4° is what the IS should use. With the 6° on an IS I sure hope you are using premium fuel. |

#1 on what chrisj said....the gold wing 1500, and the valkyrie interstate both should use the 4-degree trigger wheel. the 6-degree wheel is too much advance with the computer that is on them.

all use the same OEM TW. I/S ICM has a faster steeper advance curve to 3k than non I/S, after 3k rpms, the curves are the same for ALL ICMs all models. This is the ONLY difference btwn the I/S and Standard ICMs. see curves here, http://timskelton.com/valkyrie/tech/trigger_wheel_plus_dyna3000.htmwhich also shows area that the ECM mod affects 6 and 4 TW reduces HP at higher RPMs, the ICMs also have a HP reducing spike in the curve at about 5800rpm, "the engine hates advanced timing settings much above 25-27 degrees at rpms above 5000", "According to Hondatek's data the 1520 will actually lose 1 HP per degree over 26 total." plus a rev limiter at 6200rpm http://timskelton.com/valkyrie/tech/trigger_wheel_plus_dyna3000.htm |

ok. so you are saying actually with the trigger wheel dosen't affect the low end rpms. AND that the Std. is suppose to rev. quicker. Sorry if ignorant on this. Would it be to my best interest to go back with the oem. or maybe a 4deg. I do run reg. octane and don't get any clatter. But I have noticed that on a incline don't seem to have the pulling power I would like. Kinda disappointed in the beast right now. Thanx

I'm not a big fan of the aftermarket triggers.. I've tried 'em and removed 'em..
But, between the extra weight, the trigger and maybe the exhaust is all of what is causing your bike to be a bit slower.. A vacuum leak or dirty or different air filter could contribute.. Plus, not all engines are created equal, some just run better than others.. Thats one of life's little wonderments.. After awhile you'll just relax and sit back and enjoy the ride..

I have a six degree wheel on my 02 standard an it runs like a raped ape no pinging an I use regular gas.I have natural low blood pressure and if I get on the gas from a stop full trottle I get dizzy an Have to back off.I would like to take the valk to the drag strip but don't think I could handle it.

Good to heed what CA says! You wont necessarily hear detonation before damage can occur. Exhaust modifications will reduce the performance of your Valkyrie. Weight consumes horsepower. The other bike may just be faster. *** |

I had a 6 degree trigger wheel on my 03. When I swapped the ICM to the Interstate ICM, I had to back down to a 4 degree trigger wheel. Added the Interstate carb springs and I have tremendous throttle response.

So would interstate carb springs make my 97 take off like a raped ape? Do they really make that big of a difference? |

Need to more clearly define "revs up quicker". |

ok. By just sitting on the bike. The throttle had a quicker response. One thought. I have the k&n filter with the foam pre-filter on top. That could be restricting the air intake. (Cleaned it awhile bk. so is not dirty.) What ya think? Also, Do the trigger wheels affect rev. up as mentioned?

Remember the 98 had more HP than the later models. It was not de tuned like the following years

So, your talking about engine revving while sitting still ??!! I'm not touching that.. Its been well covered..
The detune was supposedly in '98.. The 96 and 97's supposedly had different needles [carburetor numbers are different and needles are the only thing I've found different],, but, there were also rumors years ago about the camshafts being different but no part numbers were given [that I could find] that differed from 98 and beyond..

I have the same set up. '01 Standard. (43,000 miles). 4* trigger wheel. Interstate ICM. Interstate carb springs. I do run Premium NON-ethanol gas. very happy. |

Always liked the throttle response of the I/S over the Std. Did the I/S mods and the ECT mod and am very happy. My 97 (with 2000 carbs) runs great. The trigger wheel mod was trashed after trying the ECT. One day I'll rebuild the 97 carbs and re-install. Just too lazy now to dig into a pefectly running Valk with great gas mileage, if I lay of the throttle.
