I just installed the 954 throttle bodies on my 929. It ran at idle in N and when I tried to ride it it seemed to get really rich down low (lots of smoke strong gas smell from exhaust) pulled hard in the middle then leaned out really fast. (Oh and it was smoking and gas smell at N also from exhaust) Now it will not start at all I have tried no map, every US 929 map and 954 map you can get from power commander. I am supposed to go get a custom tune but they can't do it if it doesn't run, right? Any ideas? Thanks ahead of time for any help.

maybe the fuel pressure regulator is dead....not the throtles.

Could it be fouled plugs?

 

[gsxrfxr]

no plugs would not do that, you have the 929 throttle bodies? swap the fuel pressure regulator and see. let me kno how it goes.
p.s. i just checked the part #'s they are exactly the same.

I would agree with the others, check the FPR.

Got out today and changed the FPR and still didn't fire up. Checked the plugs and they were fouled big time. They are new iridium plugs so I tried cleaning them before getting new ones, fired up first try.

so how does it run now?

 

[DingDongGo]

Runs like sh1t until I go get a custom map. But alot louder hurts my ears

Have you looked at changing the map or tried any others?

 

[DingDongGo]

I tried a zero map and every US 929 and 954 map from powercommanders website. I have been told that all of their maps are rich any way. Those are the only ones I have on my laptop. It sounds like there is alot more power to gained from the bigger throtle bodies sounds a lot more throaty and deep. On a side note I really am thankful for all of your advice bladeracer.

Have you tried actually leaning some of the values off though?

I wouldn't know which way to go if I was to change the values. Is the higher the number the richer it is? or vice versa? I wish I knew more about tuning I would love to try to get it closer to running ok at idle. I could post the map I am running.

if you are running pc3 attach the battery to it to turn it on and try leaning the low range below 0, lower to go leaner it gets.

Higher numbers are richer, lower are leaner.
