Throttle body issue

[major911]

Is this throttle body problem only inherent to the RT's or does it affect the RS's as well? Sorry if this has been addressed in another post i couldn't find any reference. This is really clouding my decision on whether I want to go with the RT or the RS.

RT Problem= RS has throttle cable.

Pretty sure the throttle bodies are only on the '10 RTs, and the occasional ‘11. Haven't heard of any issues with the '12s

There might be some software issues with the throttle body control of the 2011 and later model RTs. I think that it all started with a "hot-start" issue and then kind of snowballed. :gaah:

Well I thought the opposite. I thought it was the 2011 rt. Because of the diffrent software that kept the bodies open or closed longer after turning off. Never heard of too many 2010 rt. Anyone else want to chime in please do

The 2010 models had a different issue. Not sure what it was, but mine quit and had to be replaced... :shocked:

I would not let the TB issue decide which bike you choose. One would have to think its getting sorted out. I have a 2011 RT, and reluctant to jinx myself so i'll just say things are fine:lecturef_smilie:

throttle body issue

I had an issue with the throttle body with my 2011 RT. I took it back to the dealer 4 times but never got it resolved. It was also not diagnosed as a throttle body issue only a software issue. When i was at the Owners event a couple of weeks ago, I had the same problem and took it to the service tent. The techs knew right away what the issue was and tore the bike down and replaced the bad unit....at no cost! the company even called me last week to check on the repair! I can't say enough good about the company. They were awesome!

They told me this only happens on rare occasions.

After all; the GS/RS models can tend to burn up their exhaust gaskets..

Now thats the kind of service I expect and respect. worries me that it went undiagnosed the previous 4 times though. Obviously it didn't keep you from riding.

I have experienced the "hot start" issues with my 2010 RT. So far, have not had any issues with the new 2011 RT. 1700 miles so far.

 

[Arr MiHardies]

At risk of jinxing myself before a big trip, I will say I have had zero major issue in 9000 miles.

Trafho:

What problems/symptoms where you experiencing? We've had the hot start issue as well as the bike cutting off at stop lights. The bike is now in the shop for the 3rd time. The tech says its not the TB but is replacing the purge valve. Still waiting to get it back to see the result of the purge valve replacement.

I must say I've been very disappointed in my dealer in getting this issue dealt with. Sounds to me like they don't seek out much guidance from BRP.

I wouldn't let the throttle body issue be the deciding factor on your purchase. BRP had a couple of false starts, but they seem to have addressed the issue well with the latest fix. It has been an inconvenience to most, but few 2011/2012 owners have actually been stranded by throttle body problems. Choose your ride based on other factors, not this one. Any machine can have a flaw that needs to be corrected.

correlation between oil level and throttle body problems

Has anyone looked at the correlation between the oil in the air box and the throttle body problem.

I have seen two throttle bodies replaced, and both bikes had oil in the air box. The throttle bodies seemed to be gummed up in the throttle shaft bushes which did not allow the stepper motors to drive the throttle open and closed properly, thus putting them out of sync via the throttle position sensor to the ecm unit.
When the shaft bushes were cleaned with car-b-cleaner they were moving freely and not sticking. Unfortunately these throttle bodies were not reused to prove this theory.

Fortunately my throttle body is fine so far!!!

My air box has always been dry when checked and I think it is due to the fact that I always change my own oil and measure the oil exactly to spec. The oil level never shows on the dipstick when I do this and warm up as described to check oil level. I am not tempted to add oil as I know I have put in the correct amount (as per manual).

I use a piece of aluminium welding wire (2.5mm) and dip right to the bottom of the oil tank, compare this to the length of the dip stick and the level is about 1mm (1/16") below dipstick.
There is plenty of oil in the tank and I have never had an oil problem in 40,000K's (25,000 miles). I think BRP may have made a mistake with the length of their dipsticks.
I am considering turning up my own dipstick to replace original, just make it a little longer to reflect full when correct amount of oil is poured into engine.

And now that ALL of the Spyder models have throttle by wire systems; let's all hope that this issue has been resolved by BRP! :thumbup:

My 2011RT is having the throttle bodies replaced as I write. It did leave me stranded and I had to put it on a truck and send it back to the dealer. At the time BRP Australia had no throttle bodies in stock, even though I still maintain that this is a common problem (which they deny). I will have been off the road for three and a half weeks by the time I get it back and it may well have been longer had a contact in BRP not looked into it for me. My understanding is that this is mainly related to 2011 models.

Would I let the issue influence me to not buy an RT? Hard to say but I'm having some regrets after buying the RT two months ago and already it's been back to the dealer twice on the back of a truck (different issues).

Could it be the gas thats gumming up the TB?

SC92.....you may have hit on the problem causing some TB's to go bad: "gummed up bushings". Couldn't this well have been caused by gas? Perhaps the various software changes BRP have made which affect the opening/closing of the throttle (plate?) were a result of this and hopefully have now fixed the issue.

Perhaps a dose of carb/injector cleaner in the gas tank every now and then would be useful. This is all a WAG on my part as I'm not much of a mechanic.

It is my belief that the oil in the air box is being drawn into the throttle body by the air flow and this is what is gumming up the throttle shaft bushings
