Hi all....
I just bought a 97 Valykrie and I have been doing routine maintenance: spark plugs, oil change, air filter, rear drive oil, valve adjustment, and timing belt adjustment. I have a service manual and I checked the ignition timing. It's off a bit. I am not sure what to do from here, as the manual then goes into detail about a sensor for the coolant (forget the name of th sensor). Any help is appreciated.

The sensor in the T stat housing sends a temp reading to the ICM which retards and advances timing as the engine warms up. Did you check timing with the engine warm, hot, or cold? Maybe you don't have a problem. The ICMs for the Interstate is different too. Could you have an IS ICM in your standard/tourer?

How many miles.........you shouldnt be needing to mess with adjusting them timing belts, in fact if you snugged them up they are probably too tight and you will know real fast because they will howl if too tight. Im also wonderiong what you checked to know its "off a bit" If the left and right "up" marks and the 1/2 mark all align straight across then the timing is set...there is no adjusting short of changing the trigger wheel or the ICM |

since you just bought it, check the pn on the ecm and check the timing wheel it may have been replaced with an advanced wheel.

Thanks everyone for the advice. I checked the timing with the engine cool. That explains it.
I have been away from biking for 12 years. Happy to be back in the saddle. Working on the Valkyrie reminds me of the time I worked on my Honda ATC 90 back in the 1970's. I learned a lot then that I apply now.
Thanks,
Bill

Im still curious, you didnt answer my question. What did you check while it was cold and how did you determine it was off a bit |

Being that he just got the bike, he may not be comfortable taking it apart far enough to see the trigger wheel. That is a bit of work. |

When you say the timing is off a bit, what does that mean ?? How far off ?? And which way ?? Recheck it hot/warm and if its advanced a few degrees then its probably had an aftermarket trigger wheel installed..
Where did you set the timing belts ?? Honda says about 1/4" ,, I think thats a bit tight and setting slightly looser while cut down on the whine quite a bit..

I have only had mine a short time also. I did the same thing, changed oil, filter, diff. oil, plugs etc. Engine pulls like gangbusters to the red line, starts quick, has immediate throttle response and doesn't knock. So I figured "timing must be good" What is yours doing that you suspect the timing to be off?

I used my Snap-on timimg light and the timing mark (number 1 piston) 1.2 was below the timing mark by about 20 degrees (cold start).

Dude, this bike is far from that 90. Take the front cover off and line up all the marks like the shop manual shows. This will be your best bet and leave the timing light in the box. Pay particular attention to the squence and the length of the bolts as they are different. There are many excellent mechanics on this blog that have no problem helping. There is a very informative Shoptalk section with this site. I advise you read the articles.
good luck.

well, thanks for answering....Im glad you were using the light. If the ups and the 1//2 mark are all aligned theres nothing more you can do........if the stock trigger wheel is in and the stock ECM and the timing is still off with the motor at operating temp.......my money is on a belt one tooth off or so
