Pissed Tiger Issues - Idle and Cooling

Ok, so the Tiger is an awesome bike, but it's really wearing on my nerves. It's only got 4k miles it, I shouldn't be having issues.

1 - I think I'm having the famous "stepper motor issue". The bike usually runs fine when I start it, but after it's up to temp, it sporadically won't idle. Sometimes for long periods of time. Runs fine if I give it gas. From what I've read, it sounds like the stepper. One of the guys on here (can't remember the name) said he got in there and lubed the linkage with some penetrating oil or something and it ran for for thousands of miles after that so I think that's what I'm going to try next.

2 - Has anyone else ever noticed bubbling in their coolant expansion tank when the bike is hot? When I stop after the bike is pretty hot (lots of stop and go in warmer temps, I can hear "gurgling" in the expansion tank and it looks like bubbles from the coolant boiling. The temp guage has always read the same, no matter the temp outside once the engine is up to normal operating temp. So it doesn't appear to be over-heating but I can't explain the bubbles. Anyone else seen this?

I would take it into my local dealer's service dept in north Scottsdale, but I've found that it's easier to just beat my head against the wall at home. I know that they know about the stepper issue in general, but when I rode it in, naturally it picked that time to quit stalling. So they said they would put it on the machine and maybe reset the TPS, but I really don't think that's what it needs. No problem for them though, a hundred bucks here, a hundred bucks there. It also didn't start happening until right after I had the bike serviced there, but naturally their response is "we didn't touch anything that would affect that...."

My Tiger bubbles and gurgles during hot temperatures after a long run, too. A few times it has spit out coolant, as well. The temperature display never moved higher than the normal 5 bars.

I asked my dealer about this, they said it's normal. *shrug*

I have had to top up coolant a couple times, but usually the bike will spit coolant until it reaches it's normal level of coolant--to the "low" line in the overflow tank while cold.

Love it when the dealer tells me it's "normal". Just like engineers designed I'm sure. Thanks for the feedback.

Ha yeah. "Not unusual" is a far cry from "working as intended." Perhaps the radiator pressure valve is leaking a bit, allowing too much coolant into the overflow. Whatever the cause, it has not been a serious concern. Just an occasional annoyance.

30K miles in and I haven't had a serious problem, FWIW. Hope you can sort out your idle stepper motor issue and enjoy the bike.

Cleaning and lubing the stepper motor is a pretty easy thing to do. Dr Google and Professor YouTube will give you all the information you need to know about how to perform the task if you want to go down that route.

The gurgle is just coolant not being circulated in the head after shutdown. It boils a bit and pushes some to the tank. Completely normal. If you don't like the burble then let the bike idle for a minute before shutdown to allow the head to cool a bit more.. no gurgle
The stepper problem is a pain I agree..

Found it!

Even with the sealed airbox and snorkel running under the seat I still managed to get mud in the airbox and in my filter. This filter only has 4000 miles on it.



I cleaned the stepper up and lubed it per the method The Haymaker described in one of his posts, with some high grade CLP. So far so good. Idling well and I can see the bike adjusting the idle RPM between 1k and almost 2k so the stepper seems to have it's full range of motion back. Fingers crossed it will last.

Hat tip to The Haymaker on the tip with the CLP.

Thanks for the feedback on the bubbling in the reservoir. Good to know it doesn't sound like it's a serious issue.

Hey sponge how are you doing? You can bring that Tiger by the house anytime it needs some love. Going to have Dealer Tool and the tank extensions soon to do 12k service. Just need to teach a couple classes for the dough.
