Are you happy with removing your EXUP Valve? : Yamaha R1 Forum

2qk4u · 01-02-2013, 10:33 PM

Just wondering who all noticed or is happy with the difference in removing the EXUP balve. I have a 2006 and installed the Factory Pro velocity Stacks and removed the exup valve at same time. I can tell a difference with the stacks. Not 100% sure if I lost any bottom end or not with exup valve removed. Road a friends stock 2006 and for some reason I think it might be a small amount peppier on bottom down low but it may just be me bike runs awesome though. It's not a tuned map for my bike but its dam close I think. I have race baffles, pc3, FP stacks,smog block offs, stock gearing and gytr filter. Just looking for opinions on how u all lined your bike after removing valve. If any of you went back to it. Thanks

Go -1 on the front will be much better

I am happy but I have smog block off plates K&N filter -1 front sprocket and flash tune with a&r pipes and the cats taken out. I did most of it at the same time so I'm not sure how much the exup did or didn't do but the bikes way better now. On my 03 I took it of with less mods and also couldn't tell much of a difference either way. You also loose some weight and if you exup isn't adjusted properly it can realy hurt performance.

Can u flash tune a 2006 ECU? If so how do I go about doing that?

No 07 and up on the R1s
Sounds like you have done most of the bolt on mods for your bike. Try -1 on the front sprocket there cheap and pretty easy to change.

What exactly does -1 on the front do?

CARBONAR1 · 01-03-2013, 02:59 PM

-1 on the front, and/or + 2 on the rear...shortens the gear ratio between the engine and the rear wheel. It gives you better acceleration for the same throttle openings, getting you to top speed in each gear more quickly. The trade off is you lose top speed, and your speedo reads high. But the gain is fantastic and makes your bike feel much faster from a closed or small throttle.

Need clarification - the plug (to the exup eliminator) seems long and would definitely be in the way.. Looking for some pics of it installed....... Thx!

Once you have removed the exup motor, there's no need for the wiring harness to be down there at all. I plugged the exup eliminator (ee) in, and re-routed the wiring along the inside of the frame. And fixed the ee to the side of the fuse box, under the left side fairing.

Thanks guys! I was looking at it thinking "where the hell can this go to look clean". Thanks!

Hey 2qk4u, I've got an 06 with similar mods. I kepy my exup for the bottem end though. I absolutely agree with going -1. I bought an OEM front sprocket from an 02-03 R1 off ebay. It's cheaper than going with a quick accel kit and it fits right on!

You may also want to consider getting a custom map/tune. I did and WOW! My bike is a totally different beast. It pulls like it's in 1st gear through all the gears!

u cant flashtune it, but u can ECUnleashed it. i did on my 05.

I just got my M4 y-pipe and am excited to install before summer! I've never had the bike dyno-tuned but do have the Bazzaz zFI and AFM so perhaps that will get me 50%+ of the way to it's peak? I've only tuned it to 13.0 AFR ... not sure if that's optimal for Wisconsin.

I already have race baffles, smog blockoffs, and +2 on the rear sprocket so was wondering if the EXUP removal would be beneficial or not now that I'm adding the y-pipe to the mods. Subscribed to hear what others with the same mods say regarding their experience with removing it.
