Default MCM Oh My! (Oh yeah, disabled the KACR too - back on topic)

WOW!

Let try again, Wow!

Add me to the list of believers in the MCM! The mod went effortlessly and when I got to my test ride (after dark and the road was wet) it fired up with just a bump of the starter and I took a quick ride. Here's my initial impression, and I'll report back once I get some miles on it...
So, rolling on the throttle it truly does feel stronger everywhere, but certainly in the upper half of the tach. Grabbing the throttle the bike just comes alive from down low and pulls much harder over 5k. I don't know what an additional 5 hp really means but I do know I am no wheelie king and don't know the proper technique, but leaning back and grabbing a handful of throttle in 2nd gear lifted the front wheel!!! The bike did not do that pre-MCM!

Marcelino you are a genius and a gentleman for sharing!

KLX678, your advice has again been spot-on! I took a short ride and stopped and restarted the motor several times when I got back to my shop and it lights off right away with just a bump of the starter, no cranking! There is no suggestion of strain on the starter motor on hot start. I also used your abbreviated "How To" in addition to reading Marcelino's write up (over and over) until I understood clearly.

Upon initial impression, the MCM and the KACR-disable are winners!

Thanks all for your helpful input and encouragement! I have the day off tomorrow so if the weather if good I'll put it through its paces and report back!

Most significant mod to date!

TC!

Good to hear. Can you list your modes and jet settings. I'd love to do a wheelie in second gear. I'm no where near that amount of power in the lower RPMs.

Thanks

Part of the wheelie thing is where you sit. I slide up near the tank so even the 650 won't float the front end for me. Riders that are back a bit more, taller riders for sure since I'm only 5'6" as well, may have much better results.

I will say the 650 will easily power wheelie away from a stop, simply a bit of extra throttle as I ease out the clutch, front end floats away quite effortlessly - fun and easy on stuff.

As mentioned, I have no wheelie experience and I am sure KLX678 is correct about rider position. I was leaning back but on the pegs and can pull the front wheel in 2nd gear - though not before the MCM!

Ruggy,
I have the normal mods, UNI filter, DJ kit with 38 pilot, 128 main (though klxster is confidence there is more power to be had with a larger main), the DJ needle set per the instructions, MCM, FMF power bomb and Q4. I think a significant contributor in addition to the power mods is my gearing, I ride mostly off-road and run 14/48 - two "steps" lower than stock.

I will looking into possible jetting changes, per klxsters suggestions, but am quite impressed with the effects of the MCM!

Still in the early stages of shaking down this setup, but the KACR disable appears to make my bike start much quicker and easier, with no evidence of strain on the starter motor, another plus!

Will update as I go, thanks to all for their help and direction! This is a great site!

TC

The hallmark of a well done MCM is instant starting - KACR or not..

Tim, it's not my opinion, look at my dyno testing thread - it takes a DJ144 at/near sea level to properly fuel the mid to top end of your bike.. 1N keeps the midrange from overfueling..

Hey Klxster,
I hope my comments were not taken as disrespectful. My intention was to carefully chose my words to say that since I was only reporting initial impressions that I would be very attentive to the lean condition you cautioned about and that I would be heeding your advice when I go through the tuning process. When I said that "though Klxster is confident there is more to be found through jetting," I again, was acknowledging your research, not questioning it.

If my eventual setup ends up being leaner than the 144/1N, it is only because of the range or elevation I ride in, but that is a different subject!

I appreciate your research and sharing the results! The dyno thread is awesome.

TC

Well, I didn't know, if you knew, that I'm not dreaming this stuff up.. Sometimes I am a little "overly enthusiastic" in trying to get the word out that dyno testing indicates the need for "newfangled" carb setups..

Sweet! Just didn't want you thinking that I was diss'n you!

I've got the 132 main installed (the largest one I have at the moment) with no needle adjustments and have a ride on the Olympic Peninsula this weekend. No elevation extremes but I hope to get a better feel for the MCM

TC!

I just press off the KACR and left it off. The bike starts very quickly now and still cranks normally. I was quite surprised at the weight of the KACR and it will save some weight on the reciprocating parts. Seemed to rev somewhat quicker.

Even though the cams are 1/2 crank speed, that is still 4000 RPM @ 8k on the tach.. You certainly make some kind of difference without that damned, heavy, thing on the exhaust cam..
