i just bought a 955i back in oct. and i have a little over 1000 miles but it doesn't seem like the bike has alot of power. every time i try to give it throttle it just seems to bogg down it will finally wake up but then it time to shift. is there any suggestions

what do you have for an exhaust? in general you have plenty of options if you are of a tech mind set get a Tune-boy and fix your fuel curve or go to a dealer and have them download one of the triumph maps for you. Have you changed the sprocket ratio yet....the factory set is awful tall and a few teeth make a huge difference.

i havent done any thing to it i was looking at some exhauts but dont really know which way to go. what kind of maps do the dealers have and at what price

I use the Tune boy so I don't know what the dealer charges, if it is bone stock get the pipe (the wolf pipe looks real good) and change the sprockets (many sprocket threads to look up or pm BradTX) THEN get the TOR map for your bike and it should be way fast.there are lots of exhaust threads to look through but I've heard only good things about the wolf systems.

:-D :-D

It sounds like a FI problem. Have somebody else ride it to see if they notice the same problem. If you trust anybody else to ride it that is.

Or, just take it to the dealer and have them look at it.

This is really the best advice.

I mean, stress_reliever wrote: "every time i try to give it throttle it just seems to bogg down it will finally wake up but then it time to shift." This is not a description of a bike that merely hasn't been tweaked enough or had enough aftermarket goodies glued onto it--it's just pure-D not normal for that engine, period!

Let them run a diagnostic on it to make sure there's not an air leak or a serious throttle body imbalance, make sure the sensors are working correctly (if it's not the throttle bodies, I'd almost bet on a sensor), let them refresh the EFI map if they think that has anything to do with it (it could, if you were not running the stock exhaust system, for instance), and thereby be sure everything is mechanically and electronically up to snuff before you go dinking around with band-aid "fixes."

You can't cure pneumonia with Nyquil. No matter how much of it you drink.

I noticed a similar thing after getting my 02 955, I have since put on a Scorpion slip on exhaust and I have a lot more usable power down low and through the rev range. You might want to put a good quality injector cleaner through it as well, something else I have done recently and noticed benefit from. It may just need a good going over with a Tune tool to set up the injector mapping.

many people have suffered this complaint, as mine did to a slightly lesser degree. It seems to be attributed to lean factory mapping.

AFAIK there is nothing wrong with any of them per se, but i do know (from my mapping efforts) that remapping makes worlds of difference.. like it is not the same bike at all.

thanks for all the input i will probably start with remapping the fuel system and go from there.

i don't really wont to take it to the dealer because they are about 80 miles away and last time i was up there they could not give me much input.

My CE was peppy but not great displaying to a lesser degree stress_reliever's symptoms, until I played with the setup a bit (exhaust + mapping). Now it idles great has gobbs of low end and pulls very strongly through ALL the gears to red line, second gear unintentional power wheelies above 6000rpm are common, and I'm not a little guy to haul around. At the time the dealer loads a tune for you they should check for any error codes. but have it checked soon if you can even if you make no other changes.
