trigger wheel

[FryeVRCCDS0067]

Tech question. My son's valk has a trigger wheel installed. And, as frequently happens with trigger wheel equipped valks, it doesn't like starting when the motor is cold. I assume that's because when the thermal sensor that advances the timing when the motor is cold does its job, it's advancing the already advanced timing the trigger wheel created. Which is too much advance for easy cold starting? Does this sound correct?

 Assuming I'm right about this, can the problem be solved by disabling the thermo sensor? Has anyone tried it?

If so, how?

I had a 4* on my 98 Valk never had a problem with cold temperature starting. You do remember that when you THINK you have the choke all the way on there is that last 1/8-1/4 inch that you have to push a bit harder to get full choke. I’d start mine once a month through out the winter if it got to 28*to 30* in the unheated garage.

Yep, I do. It's on all the way. But I appreciate the response. Thanks.

I also had the wheel but never had a problem starting. Usually poor starting is due to a lean mixture more than timing.

Usually 6* in std and tourer, 4* in interstates.

One of my interstates came with the 4*.  I don't recall hard starting, but I knocked on regular unleaded, so I went back to stock and gave the 4* away. 

A common reason for hard starting is the battery, when there's enough juice to turn over, but not enough juice to fire up.  In this condition, sometimes the bike will fire up when you let off the start button.

After I went Iridium plugs cold starting is way better. On a note 10,000 mi. is recommended change on stock plugs. Mine twice had failure just over 10,000 mile. Iridiums been in over 12,000 mi. and started 1st. stab this spring after 5mos. sitting using Supertech fuel additive for storage the past 4 seasons. No sluggishness compared to Stabil.

I agree on the Iridium plugs.  I use them on my car, truck, and bike.  They last a long time.  Over 60K miles.

A lot of guys have run the bone stock Nippon Denso for years at a time.

Mine come out looking perfectly tan and entirely unfouled, every time.
