Booster Plug

I have the ICEE from poolside over on Adv. Rider. It's about $80 bit takes a while to get. I've had 1 on order now for 9 months! Should be here soon. I knew going in its a side /moonlight situation for him...he's sold hundreds. It's a quality peace that has three settings. Worth the wait I guess. I got lucky and found a used one a few months back it's on the GS. will try the new one on the H ...when it comes. I'll let you guys know the results.

I just received my dual switch Wuka-WoWa! Where did you put your temp probe? The lead is fairly short (sad).

And where dd you put the switch? That lead is fairily long (glad).

Just curious ,

Ok so I ran across a deal on a brand new booster plug and bought it. I have a similar gizmo from an inmate over on adv. rider. Does pretty much the same thing. It did help with the slight hesitation the GS has off idle and just general better throttle reinsponse ..less popping and cracking on deceleration too.

The TR everyone has known was too lean out of the box. I have a good dealer and had the Moss done. It helped a lot. The dead spot down low and less than perfect fueling I figured was just something I'd have to accept. Kinda like a small block chevy with a little too much cam....kinda bucked and jumped...waiting for uou to nail it.The price you pay for a hot rod. Team H did a good job IMHO. They probably could have fixed the leanness if it weren't for emission crap. No way around it I reckon. Well WRONG...I WAS,!

The booster plug fixed what was wrong with my Strada. Period! It idles with a authority now that before it just didn't have. It likes to lug down low. Now it would do it before but didn't like it..I just delt with it by dropping a gear ...or two. The little H liked to stay "on cam" so to speak. I was happy to Let er rip! Well now she'll do both equally as well! BP should mail one to every TR owner for a trail. I don't think they'd get one returned. It took my TR to another level of enjoyment..

Glad to hear you sorted out the niggles with the engine on your strada.
How does the ICEE differ from the Booster plug and the Wuka king plug? 3 settings you say ?

I zip tied the sensor to a cable on the left side of the steering head out in the clean air as far forward as it wound reach. I rolled up the extra wire and zip tied it inside the left tank cover. I routed the switch through the channels in the tank below the cover and zip tied it to the fuel line at the tank/ fuel line clamp, then I put the red and blue tape on the tank beside the switch so I can get to it by taking off the seat. There are 2 settings above 85 and below 85 I am running it in the over 85 hot weather setting. This fall I will try the cold setting. It runs fabulous.............

The details are over on adv rider. Poolside is the inmate who sells them. The only way I'd consider buying another is on the used market. He just takes WAY too long to deliver. It's a moonlight type operation....so he has a real job. This thing just exploded for him I reckon and he can't keep up. Very quality product and a bargain to boot....but you must pay in full up front and some have waited 6 months or longer to get the thing. All those gizmos get to the same end...and the TR really benefits from this. Some other bikes maybe not so much? They do come up for sale used but are gone pretty quick.

I see his paypal add to cart buttons - but there is no designation for the TR650. Is it all the same piece - GS or Husky?

F 800gs has the same connectors. That is what I got from wuka king

Yes...same for the TR..it's plug and play. Very easy. I had emailed poolside..( the seller) and asked about fitting the TR. he thought since it was BMW/Rotax it would work....it's since been confirmed...it plugs right up. The difference is its adjustable....with several tempatures to select...it's kinda like a toggle/switch. If you research the thread over there you'll see plenty of pics and tons of info. It helped my GS...but it TRANSFORMED the TR.

I am not making HP / Tq. Claims...neither does he as far as I know....but the throttle response is seamless. The idle is not nearly as loopy. It's not stumbled once since the BP. Since being Mossed the engine has only died a couple times in 2k miles...I don't think she'll die now with he BP..you can just tell it likes to run too much. Doing a long distance trip. Leaving tomorrow from Knoxville and taking secondary roads all the way to central Florida....that'll be a test for certain. I'll check in here along the way if issues.

Out of the blue my Terra picked up the evil stumble. I ordered the Wuka King based on the excellent results from any of the Booster Plugs and especially from High Fives report on ADVRider http://www.advrider.com/forums/showpost.php?p=21653795&postcount=1021. Will have to live with the stumble for a long road ride this week-end. Will report on how it works after I install it.

BTW, the Booster supposedly works by fooling the temperature sensor which leads to richening the mixture. I sure am liking my 58 or so mpg I get now and would not welcome any reduction in range after I add the Wuka King. Have there been any drastic changes to the MPG as a result of any of the booster plug use?

After getting my TR Mossed a couple months ago, I was pretty pleased with the improvement - though it was not perfect and still prone to the occasional stall.
Since buying another bike a month ago, the TR has sat unridden until this weekend. It was a little depressing how shitty it ran off idle today, and leaving a stoplight took a deft touch to do it cleanly.

Once it got good and warm it got a little better, but it has nowhere near the off idle snap I expect from a thumper this strong.
I depend on that snap quite a bit riding offroad.

Good chance I'm going to pick up either a BP or Wuka... and I'm the guy that never goes the PC route, and have only re-chipped a handful of injected bikes over the years.

Terra 650 “Wuka King” install

This weekend I took a shot at opening up the Terra and installing the “Wuka King” type booster plug.
They have two versions; I bought the $90 version with the 2-position switch. (So far, I’m glad I opted for the switch – more on that later)

No riding impressions yet, I have a 25 mile commute in the morning. That should let me know what the effects are.

Well, the first thing I’ll say about taking the dashboard and side panels off is,
Man, there are a lot of screws to remove! And it’s my personal pet peeve, but it’s a variety of fasteners as well.
Mostly star bit, but one Phillips and 3 hex for the air filter cover. Make a decision and stick to it man!

I used HighFive’s excellent write up on advrider to get started.

The disassembly order is: dashboard, side panels (upper and lower) and then radiator cover.
High Five took off the red side cover and lower covers separately, but I found it easier to remove them together.
The last start bit holding the bottom cover is UNDER the red upper, but when everything’s loose, you can get to it.
Hell, I couldn’t figure out how to separate the upper and lower even with them off the bike!
Looks like they would as likely break as come apart.

You probably don’t need to take off that much to just do the booster, but I wanted to do a radiator burp as it had overheated once already.
Funny little side note, the friggin’ radiator overflow tank is ABOVE the radiator. This means if you stand the bike upright (like I did) and take off the radiator cap (like I did),
gravity pushed most of the fluid out of the overflow canister and consequently overflows out of the radiator spigot.
This really freaked me out. I’d never had a COLD radiator overflow. J

Anyway, I installed my booster exactly the way Big Dog did. (Thanks BigDog). It worked out great. I opted for the Wuka sensor in the airbox install for two reasons.
First, if it good enough for the stock air sensor, it’s good enough for me. Second, the friggin’ lead is too short to go anywhere else anyway.

Here it is installed BigDog style:



All the wiring fits nicely tucked in beside / behind the air box and within the frame.

Here’s a close up of how I mounted the sensor:


I found a drill bit that provided a tight fit for the sensor, and used the cool little cable tie sticky on the radiator overflow tank.
I thought about maybe using a rubber grommet or silicone to seal around the sensor, but the fit is nice and tight. I’m not worried about it. Especially with the cable tie like it is.

Here’s where the bulk of the harness lives.


As someone had mentioned earlier, be carful! This is where the throttle cable and throttle body are. Leave some space:


Unlike the sensor lead, the switch lead is very long. I decided to run it along the side panel and under the seat.


Relatively easy access to the switch:


So, it did indeed only take an hour or so, and wasn’t too mind-boggling. I’m a stickler for clean installs, so I took my time.

Before I buttoned her up, I started it up to make sure it still runs. J I initially had it on the RED position (-38 degree shift) and it idled quite high. Immediately switching to the blue setting (-18 degree) dropped the idle to just a little above normal. (It was probably in the upper 70’s or maybe even 80 at the time of install, so the blue setting makes sense.) Again, I’m glad I bought the switching model. I like options.

Well, I have 25 miles each way tomorrow, so I’ll report back with my impressions. My bike was mossed at 700 miles and have 1500 on it now. Definitely runs lean, and feels mushy below 4K.
A single shouldn’t feel like that. I would be expecting torque down there.

I can't understand why they are so temperamental for an engine with EFI. In comparison you hop in you car, start it & drive away. No stalling, flatspot or backfire. Why can't the 650 be the same? With my carb KLX, start it, let it idle while I put on my helmet & gloves, put it in gear and away I go. Don't have to slip the clutch or not grab a heap of throttle until it's at operating temp.

It's interesting that there is so much variation between bikes. My Strada with only 650 miles was "MOSS'd" when I bought it and it seems to pull pretty strongly from 3k and very much so from 3.5k. My booster plug is due in today's mail, so we'll see if it makes any difference.

Ok, Wuka King plug installed. Cold idle 1600 rpm indicated. Hot idle indicated just under 1500 rpm. Book idle speed 1550 rpm. Close enough for me. Definitely smoother on initial clutch release with a bit of throttle. No hesitation and it seems to be a bit smoother from idle to 3k. It also seems to be a bit more responsive from 3k up, but mine was never bad in that respect. I installed the probe where High Five installed his (Adv Rider post) in the forward edge of the front left side fairing panel. However, I installed the switch under the seat parallel to the frame rail in front of the battery. I don't anticipate having to change the switch -- time will tell.

Well I said I'd report back after my trip from Knoxville to Orlando and back. Trip was great...the TR ran as good as any motorcycle I've ever owned...and I've had a few. Worst fuel mileage I got was a stretch where I didn't drop below 80mph...saw a indicated 90- 95 mph between Asheville and Knoxville...49 mpg.. Sounds awful but I think it's great. Pretty much WFO for nearly 100 miles...never skipped a beat. Didnt use any oil that I can tell. Chain didnt require adjustment..I bet I got asked....or rather told that "I didn't know Husquvarna made motorcycles" about 10 times during my journey. I reckon Husquvarnas are rare down yonder.
I never wished once during my trip that I'd ridden my R1200 GS instead. I think that says a lot. It's not like I don't like it too. I do....I just think the TR fits me and loves to be ridden hard. Already planning my next trip!

+1. What they all said. My wuka King plug arrived today. Quick install in the 30 mins I had before the sun went down so I didn't have time to do a neat install but took it for a quick ride and definitely a difference. My main issues with the stock Terra was the initial hesitiation at low revs particularly from a standing start. Now, it will accellerate without clutch from about 1700rpm in 2nd gear uphill. I'm very happy about that.

There might be something to that... I've ridden it the last couple of days and it seems to be back to normal - which defies all logic to me.
It did go the better part of a month without being ridden, but I'd expect it to run the same regardless of how long it sat...
