Watt-Man Thermobob vs. MCP Thermal Control System

1986 Views 76 Replies 18 Participants Last post by  SirMarksAllot
Seems like these both do the same thing. Without mentioning Watt-Man's specifically, MCP says in their description "Works much better than similar options". Anyone have any knowledge of any differences between the two?

To add relevance to my thread drift... there is my 23 with a thermobob. And the red circle is the rear abs plug if you want to disable both ends of abs.

Is an MCP 2.0 needle in the works?
I haven't heard anything regarding a 2.0 needle but he has updated the kit just within the past week or two that includes a full delete on the air cutoff as opposed to just plugging it. Keep in mind the "MCP Kit" usually isn't just jetting and needle swapping but also the vaccum delete and air cutoff delete. These additional mods might be why people report better performance out of the MCP. For someone who has already bought Eagle Mike's kit, I wonder how similar the results in performance would be if doing the 'associated MCP mods' with a KLX needle. For the average rider looking to decide between the two though, it's probably just easier to go with the MCP kit.
@Damocles remember, I carefully tested the MCP kit versus the stock jetting two years ago by swapping back and forth and running the same mileage loop and acceleration tests back-to-back. The MCP kit gave a small increase in power, about 1/2 second faster acceleration from 50-70MPH, but it also reduced fuel mileage on highway cruising by more than 20%.

Did you do the 'Associated mods' or just the jet&needle?

Also did you end up trying KLX, keep MCP or go back to stock?

The original MCP claims offered simultaneous increases in both power and fuel economy, as posted on ADV.

Maybe the performance improvements have been revised.

Air cutoff valve ("backfire preventer") removal, until now, was an unknown mod, to me.

Regardless, MCP claims thousands of kits have been sold; obviously a, "better mousetrap," as regarded by satisfied MCP customers.
Oh I get it. But the rose still smells just as sweet and such. (Not that I'm into reading and parting and sorrow and all that) Ive been a mechanic for 20+ years as a hobby and recently side job. Ive been in industrial manufacturing for over 20 as a job, mostly in the engineer, tech part but sometimes management. I despise management. And ive also been into shooting sports for 30. Lol.

But maxim patented the suppressor as "silencer" and Colts patented "pistol" was a revolver. So arguing those (and they are argued at any shoot) is a bit much. And when im shooting and someone mentions their "clip" I don't bother arguing. Every 7 year old playing call of duty knows what they mean so why as adults do we feel the need to jump in. Idk. Not saying I wont if the person has gotten on my bad side and I'm feeling sarcastic or facetious. I own an m1 garand (and a few carbine but those are mag fed), Nagant, and have had a few sks... ive even had the displeasure of loading mags FROM clips. Lol

And yeah enricher, choke confuse people. But try to explain why a sequential fuel injected bike (like a victory) has a "choke" to people. Lol. Its really a fast idle but even polaris referred to it as a choke in their literature. It does nothing but pull at the tps.

I suppose if the manufacturer (polaris) calls the lever a "choke" then it's now a choke regardless of what it does. We now have a doohickey and a thermobob..... so I guess it's up to them. Idk. I'm just glad to see carbs going away from common use. Majority of the junk coming into my shop over the past 20 years has been "carb" related. To most people the "choke" is the lever itself. Regardless of if it pulls a flapper thing to block air or pulls a plunger thing to add fuel. Lol
New2kaw; even the HARLEY riders call their Keihin CV40 STARTING ENRICHERS a "CHOKE!" I stand corrected, perhaps even somewhat humiliated:



Regardless, I've enjoyed the civil TAXONOMY (nomenclature-wise) and ETYMOLOGY (origin of words) aspects of our discussion!

And the red circle is the rear abs plug if you want to disable both ends of abs.
I'll ask if you started and road your bike to turn off the ABS light, then stopped with engine still running to dis-connect the rear sensor and then proceed to Ride the bike and then use only the front brake hard Enough to either howl the front tire or engage the Front ABS.
I know that the dash light will turn back on from not getting a signal from the rear system once back in motion.

But I would think that a Law Suit could be very likely because of turning off the Entire system when only the rear-half encountered a torn wire while in motion. Maybe that is the key words, "while in motion"?

I unplugged it both before starting and after riding and verifying abs did work correctly before unplugging, then unplugged while idling. I was testing on my gravel road. The front abs was killed 100% certain. The abs is incredibly invasive on downhill gravel. No doubt it was disabled, I engage it several times every day since it's got a pretty decent grade to the road.

I found it more concerning that when i plugged the sensor back in (all while still running) that abs wasn't restored. I rode for several minutes while sliding (for science of course... not just for fun). I killed the bike via the key and abs was restored. Ill try killing via the kill switch and see if that brings abs back. If the kill switch can restore abs, then a toggle or button on the rear hall effect would kill abs on command. Then pulling the clutch and killing with the switch then releasing the clutch to restart would restore it.

At that time, the MCP kit consisted of the main jet and needle and one or two pilot jets. It did not include anything to disable the backfire preventer.

I went back to stock jetting because it worked fine for me. I thought about testing the KLX jet and needle kit too, but didn't get around to it. Several others have done extensive testing of the KLX kit versus stock, so I didn't feel an urgent need to do it yet again.

Thoroughly tested and excellent information.
Thank you.

So from all the things I have read about the MCP Kit it's now apparent that a lot of the reports of fuel mileage increase are partly due to the fact that some people had the KLX kit installed (sometimes poorly) and then once going the MCP route reported better fuel economy. So it might not be giving you much more MPG than stock, but at least might not be dropping you as much as the KLX.

The reports on ADV came from MCP directly.

Just speaking for peoples' own reports I have read. I would be skeptical if the MCP actually improves MPG over stock since the stock configuration keeps the bike overly lean. Still though, a performance increase with less of a MPG drop as the KLX sounds nice.

Just returned from 300 mile trip with newly installed 145 main and Klx needle on second clip slot (several conversations with EM to get it right, after the 142 wasn’t enough fuel for my particular bike, an outlier per EM) Yoshi exhaust and drilled Airbox/deleted snorkel. I REALLY flogged the old girl with about 30# of gear and got an average of 45mpg. 15/43 sprockets. Highest I ever got with stock and no gear loaded on was 51, with various counter sprocket configurations. Just info for the hive😉

I’ve still got to tweak the needle with one more shim, and if I can control the wrist, I’ll see if I can get a few more mpg. Right now I’m trying for more SMILES per gallon😉🤣
