I've read all the wax and thermostat threads. What first started out to be a possible temp problem has me wondering if these two are related. In regard to the temp issue, I was out late last year and noticed the temp fluctuating more that I thought it should, weather was fairly warm, around 70, speed consistent at around 80 mph. All this led me to check coolant condition, fan operation, those types of things. Everything checked out. Then I started noticing inconsistent idle. I'd set the rpm adjust for 1100 +- 50 in the garage, then after taking off and getting her warmed up, I would stop at a light and notice that the idle was up to around 1500. When I got home, with the bike nice and warm, I reset it down to 1100. Restarting a few days later cold in the garage, she starts fine, but when she settles down the rpms drop too low and the voltage actually drops to a discharge state. I had already ordered a new thermostat, but decided to order a wax unit also. May as well replace both while I'm at that level. I looked at the TPS but that is an integral part of the fuel rail (?) or so its states in the manual, and takes quite a bit of work to replace. I would think these are related as they both have to do with temperature. I also got my fuel sending unit in. When I get the wax unit I'll post pictures of all three. Any thoughts? All maintenance has been performed, new plugs, fluid, filters. She runs like a dream except for this issue. Appreciate any input. // smurf

How does the wax unit actually works?
My wax unit didn't kick in these past few weeks.Does the coolant play a part in the function?..hmmmmm

shewie · 01-15-2009, 11:49 AM

The "automatic first idlle wax unit" is shown in the FSM on page 551. It is connected to the engine cooling system by two hoses. When the coolant is cold, the wax contracts and a spring pulls an actuator which opens the idle air valves in the throttle bodies. As the engine (and coolant) warms up, the wax expands against the actuator and closes the bypass valves. The ecm will adjust fuel ratios accordingly.

But for mine when cold the wax unit didn't activate.if there something wrong??

And sorry smurfie for jumping on ur thread

You might have to do some wrenching - pull the fairings and see what's happening.

Hey its pk man,probably i need to take it out and see whether the actuator is stuck or something. i'll try to grease the shaft to see if helps.

mine SORTA does the same thing.. it will drop down to around 800RPM for about 2 minutes then it will kick back up to normal RPM... not sure what it is, but it just started happening to me recently, then i noticed that my idle temp was in the 200's.. not sure if thats normal or not, all i did was turn it on for about 20 minutes when it was -20F outside to let her warm up and get her juices flowing for a bit

X1rider · 01-16-2009, 5:49 AM

How many miles on the 00? I have 49K on my 02, with none of this problem seen.

I run Engine Ice Coolant and flush it every 18 months. I know that doesn't have anything to do with the wax unit, but maybe keeping the temp of the motor cooler it helps? Just guessing here.

smurf211 · 01-16-2009, 8:50 AM

Correction, the TPS is an integral part of the throttle body according to the Haynes manual. I have not matched that statemnet from the Honda shop manual yet. I suspect that this bike did a lot of garage time due to it being a 2000 with only 8500 mi on it when I bought it last year (October). Leads me to think I may have an o-ring or seal isse. I am going to be lifting the tank and replacing the thermostat and wax unit, as well as draining and flusing the coolant system. There is procedure for testing FI with the plug in the back to determine ECM codes which I will also be looking into. The last note I remembered yesterday was the last time I was "IN" I notice two hoses that had a small hole in them. One was a breather and one went to the coolant resevoir in the rear. I'll be taking a second look at that also, at the time I didn't have any replacment hose. Standby for some pictures and we'll go from here. No probs with the usage of the thread, the more input, the more we learn.// smurf

Hi smurf. Have I told you how much I like your avatar? Achmed is hysterical.

Have you priced the wax unit? I'm just curious as to how much they are and I'm interested to see how much time is involved in swapping it. I think greysnail may be even more interested, though.

greysnail · 01-16-2009, 9:09 AM

YEah man,interested in ur project.Post some findings too aite....

btw...Where's Walter...muahahahahahaha

smurf211 · 01-19-2009, 4:30 PM

I didn't get to it this weekend, still waiting on the wax unit. Ole Achmed was on the tube again last night, I still laugh... here's the link for those of you that are so inclined.. YouTube - Jeff Dunham - Achmed the Dead Terrorist.

Suffering the symptoms reported above, I replaced the wax element yesterday. It's pretty straightforward, but a bit fiddly.

The old unit had seized up and wasn't activating, causing misfiring and poor idle when cold until hot.

Started this morning no probs and held idle with no throttle interaction.

Here's a link to a picture of the disassembled automatic choke/wax element unit.

http://i97.photobucket.com/albums/l2...s/ATT00025.jpg

(Still can't upload a pic.)

Edit: Price was around 900 Baht (about 25 USD) took a couple of weeks to come from Japan.

Replacement involved lifting the tank removing the air filter box and removing the choke unit (water pipes, couple of screws and two smal nuts - adjuster and locknut DON'T DROP THEM UNLESS YOU WANT TO WASTE 20 MINUTES TRYING TO FIND THEM.).

Break the unit open, remove the rubber boot and remove the old wax element with circlip pliers. (Refer to pic above for broken down unit.)

Fit the new element put it back together and refit it on the bike.

Setting up involves adjusting the small adjuster nut on the top then locking it. A bit of trial and error here. Run the engine until normal running temperature and set it up to idle at 1100. (Don't burn yourself.)

Job's not as difficult as you might think.

Tools you'll need are; a spanner to remove the tank bolts, something to prop the tank up if you don't remove it, screwdriver/spanner for the airbox/coils and the choke unit screws (you might need an impact driver if it's never been removed before), and (I think) an 8mm spanner for the small nuts. Circlip pliers to remove the circlip holding the unit together, and a tasty bird with a big rack to cheer you on and bring you beer helps.

Perfect, thanx for the write up, I'll use it to go thru mine and report back also. Thailand ?, I've been to Phuket twice. Amazing place, right up there with Hawaii. again thanks, // smurf

greysnail · 01-22-2009, 10:46 PM

Pretty straight forward i guess...

smurf211 · 02-17-2009, 9:59 PM

Wax unit: Cost from Ron Ayers about $29 shipped, it is fairly easy as stated before, that is until the last screw won't budge. I ended up taking a pair of needle nose type vice grips to loosen it up enough to get it out. Of course it had to be the one that was at the 4 o'clock position that you couldn't see from the left side. It was a miracle that I actually had a replacement AND lock washer that fit. The original WU came out with a bunch of crud on it. Don't really know what it was. I probably could have gotten away with cleaning the original but not knowing what to expect having a spare on hand made sense. Re assembly was a snap. After reassembly I started her to test and the idle cycle improved but it was still a little uneven. It may be the computer has to learn or relearn input, maybe.

Thermostat: The thermostat aspect has turned into pulling the radiator and taking it to the radiator shop as a result from the wax unit check out. I noticed a very small pinhole leak at the bottom of the tank on the right side while bringing the engine to operating temperature. A new radiator is ~$400 bucks, ridiculous, so I call the radiator shop and they guessed $45 to worst case $150. So, out comes the radiator. I figured I was this far in may as well do it right. I was going to drain the coolant and change the thermostat anyway, which I have yet to do, probably tomorrow night, but the radiator came out easily. The manual tells you to move it forward and support it assuming you have the front cowl off. I lowered it down and let it rest as shown. This also gave me an opportunity to closely inspect the oil cooler and the radiator fan which both are in good shape. I should be getting the radiator back by Thursday so I'll update from there.

smurf211 · 02-17-2009, 10:10 PM

And here's the result of the radiator removal. //sm

smurf211 · 02-25-2009, 7:17 AM

Quick addendum: In reference to this paragraph "The manual tells you to move it forward and support it assuming you have the front cowl off. I lowered it down and let it rest as shown." I was referring to the oil cooler. sorry, get a head of myself sometimes.

smurf211 · 03-01-2009, 1:59 PM

Radiator returned and installed, $45 for pressure testing, cleaning and a light coat of paint. Thermostat replaced. Fresh coolant, 1.2 gallons, added. weather too crappy to take it out yet. Idle has improved quite a bit. The only thing left I'm considering is throttle body sync. Will advise. // smurf

curtis · 05-05-2009, 6:22 PM

im having a similar issue with the fast idle wax valve on my car, i have retro fitted a set of thes on my car and im trying to get the idle, i started it up at got a 3000rpm idle haha so after i eliminated vacuum leaks im pointed to the fi valve.

can someone tell me which screws you adjust to chance the cold idle? do you have to open it up to do so or is it the ones at the end of the rod right by the trumpets?

How many miles on your bike? I ask because mine has 52000+ miles with no problem like this.

Right, and you've owned your bike the entire time?

10.5k, I am the third owner and did not have a detailed history of the bike. Now I do. Why? because I went through the whole list and checked it out. Things have improved quite a bit. It wasn't any one thing but a combination of small things. After performing the radiator / thermostat maintenance my temps dropped about %15. While I had the fluid drained I took the rad in for a pressure check. The fluid to me was green, almost too green. Low miles but 9 years. Preventive maintenance. I don't like surprises during the riding season. I think this thing did a lot of garage time and things go south if they are idle and not prepped for storage properly. // sm

Tried to do a carfax on my vin with no luck. How do you get a history on a MC? PO said he bought it from a guy that owned a climate controlled garage. Anyone notice that GREEN radiator fluid. Looked like Lime jello. I just remember saying to myself, "I have no idea what that is", so when in doubt change it out. Make that 15-20% cooling improvement. Did someone put in an additive that would have made it that dark. From previous experience, rad fluid starts to turn brown with age, at least that's how it use to be with the green flavor. Thoughts, ideas, input ??? // sm

There are car coolants that when mixed are flouro green - but they are car coolants, not bike coolants.

Curley1957 · 05-18-2009, 6:14 PM

Hey Guys,

Just finished a fluid change, however did not do the upper nut on the left side, drained it all out, re - filled with good coolant.

Let run for a while to get the air bubbles out, did notice some steam for awhile but may have been the degreaser burning off, noticed that the gauge did go up to the high side of the coolant gauge (1999 model).

Any suggestions?
