Re: bogging down low with full exhaust?

my 954 does the same thing and so did my 929. You just have to give her a little more juice from the start and use a little more clutch. You'll get used to it.

Re: bogging down low with full exhaust?

Huh? A little more juice? No no no . It's the fueling. I don't care what you downloaded from where, but the fueling is either too rich (best bet) or too lean at those points. Get a custom map written for it, and the problem will go away.

Re: bogging down low with full exhaust?

No, it might not.(full erion, two custom maps made at an Dj approved site, with a 250 dyno and tuning link)

Sook's right. A custom map probably will help.

What he said.

Although depending upon the system there may always be a bit of a loss down low even with a custom map.

Re: bogging down low with full exhaust?

I have a feeling I have the same problem with my full erion system, but then again, I have never ridden my bike without an exhaust (came with when I bought). But I got used to it really quick, and it wasn't that bad for me. But it might not be as bad as yours is???

Re: bogging down low with full exhaust?

Mine bogged alot when I put the pipe on w/o the PC but after installing the PC cleared it right up, not using the right map at the moment but it still seems to run mint.

Re: bogging down low with full exhaust?

Putting a 15 tooth front on or going up a couple in the rearwill help a lot if the tuning is as good as it's going to get.

Re: bogging down low with full exhaust?

I'm using a full hindle without a PC3 and on my 929, and I haven't noticed any change down low. I always give it a lot of gas in first, though.

Something's wrong. My 929 never acted like that exept when the bike was running too rich down low, just after installing the Micron without a custom map.

Re: bogging down low with full exhaust?

Dan Kyle has a few charts of the Erion system on a 929 showing a 13 HP loss between 2000 and 4000 rpm (along with an 8 HP loss between 5 and 8) aginst the STOCK system. After custom mapping the loss on the low end was still over 10 HP in the same range. It appears from looking at these charts that the Erion is definitely optimized for top end only.

Re: bogging down low with full exhaust?

YEAH? That's fukt. The Arata system even not mapped doesn't give that sort of loss, even the Serpent which gives what I think is a big dip (un mapped) isn't that bad. Wow. Why the hell would you buy one then?
