Well I have had my uly for a couple months now and it came with the serpent exhaust, ebr race ecm(have two spare stock ones also), and a k&n filter. The low speed on this bike is horrible. Are there any tunes out there? Or would I be better to toss the stock exhaust back on the bike? It is an 06 so I assume to get a tune done at a shop I either need ecm spy or add a power commander to it. Another thing I noticed lately is that it has a hanging idle sometimes around 2k rpm going from on throttle to off with the clutch pulled in. I was thinking intake gasket?

Thanks,

Steve

Steve, first off: your username is incredible : D.

I can't answer most of your questions, but I can say that the low speed on my '06 is terrible too, even though it has the stock exhaust and mapping. Does get a little better once the bike is warmed up.

Maybe a close look at the mapping by a pro could solve, or at least alleviate that issue.

My nickname playing hockey was slacker because I never made it to practice on time. Not my fault they scheduled practice at 6:00 am. Then a few years later I got a tattoo that says Slacker but only half of it is colored all the way in. Most people think I'm a big sissy when they see it but then they get the joke.

I'll trade you my stock exhaust and cover all shipping if you want to trade the Micron for a stock setup. I'll even include the actuator and cable. The Micron does give up significant amount of power and torque down low, about 15 ft/lbs at 4000 RPM actually. But it does make more power up top. On a stock motor,it makes about 4 more HP according to American Sport Bike's exhaust shootout. In my case, I'm making almost 30 HP over stock with the stock exhaust, and I rev higher as well, so a Micron would have more effect on my motor. I don't care about losing low end as my bike is mainly an R&D project for me, with the goal of making as much power as possible.

Slacker, your hanging idle is because you're idling too high. Back your idle off about 50 rpm's and see if it corrects it. You might also be due for a tps reset. If interested I can give you a blow by blow of a proper reset but you will need at least the free version of ecm spy and a dongle for a laptop.

American Sport Bike sells a tune for Micron exhausts that works perfect on your 06. I have American Sport Bike's map on my 06 with Micron, it is fantastic, even right off idle.

You hanging idle is due to the idle speed being a tad too high, lower it a tick to fix that.

I do have a complete stock exhaust to put on the bike if I go that route but thanks for the offer. Yeah I did just raise the idle a little on the bike it was idleing around 800-850 rpm, right now it is probably 1000-1050. I have the orignial vdts (sp) that came with the bike so I should be able to do a reset with that. I'll call Al right now about that map.

Thanks guys

Steve

I did a tps reset last night and checked for intake gasket leaks and couldn't find any leaks. The tps reset seemed to help a little but I think the bike ultimately just needs a tune. Going to get some plugs and change those also.

Yep it really does need a tune with the Micron, there is an old thread out there of someones bike who ruined the pistons by running the Micron with the stock map.

"ruined the pistons by running the Micron with the stock map". Not surprising since the 06 bikes run a bit lean, over so I you ask me, as it is. That and a VERY OPEN can like the Micron is a problem in the long run.

Sounds like Froggys advice is the way to go since he has the same setup. I would be inclined to use the new flash on one of your old ECMs (it will need a TPS reset doing as well) just in case there is a problem with the EBR one.
