Is there a way to decrease throttle pull on the pro?

This is the one complaint my wife has.

 

[jpete27]

tell her it's time to nut up or shut up. haha

i would say no, but you could buy a throttle extension to make it easier. seems that would be something funky so snow bunjie should make one...

Have her ride a carbureted sled for a while.

Problem is that she has rode fuel injected cats since 1999. I see that napamatt recommended lubricating the throttle bodies. I will try that and see if it works. If not I will just wrap a rubberband around the throttle and tell her to hold on.

Be very careful making changes to the throttle block assembly. Particularly if you plan on changing it out for another. My riding buddy put a billet block on with a seperate kill switch. He is still having troubles with the TPS. Apparently the new ECM is very sensitive to electronic changes. The TPS was fried and he had to get a new one.

Why would any of that affect the TPS??

When she's not riding the sled, zip tie the throttle wide open.

That way the return spring will soften up and should make the pull easier.

Just remember to remove zip tie before starting.

I would guess that its not so much a throttle pull issue as it is she has very small hands which makes her hand tired due to how stretched out it is to run the throttle...talk to kurt at fastrax..I bet he will have an answer that will work for her..might be able to use his billet throttle block and install a cat throttle lever...I do know wrp or dennis kirk used to list a throttle assist that installed on the lever to make it easier to pull also..something else that might work as a worse case deal..roll her throttle block over so she pulls it with a couple fingers, in other words facing forward(install hand guards so nothing accidently pins it for her).good luck...

So let me guess. He had an issue with his sled's TPS, and because he had a different throttle block on it, his dealer denied the warranty basically. Sounds like he got hosed to me.

How would the ECM be so sensitive to an incorrectly calibrated TPS sensor?

Just saying...

tps shouldn't be affected by swithching the throttle block, would have to check to be sure but isn't the tps located on the throttle bodies??? it reads the position of the butterfly shaft not the actuall throttle lever itself. so don't see any relation to the throttle block and tps. if its anything like an automotive tps you would have to loosen and move the sensor itself to make any changes in its readings...

The issue with the throttle block change isn't the TPS sensor by itself, it's the TPS in conjunction with the throttle lever safety switch.

The ECU reads the the "modified" throttle lever safety switch as stuck wide open.

Yes! That seems to be the issue. I have a feeling (or guess) that the ECM may be more sensitive to voltage spikes. Maybe because of previous voltage regulator issues. I'm not certain.

The dealer is working with him on all of this.

Have her ride a 09 xp she will love her throttle.

Not sure, but my understanding is the throttle safety switch is now a variable resisitor, not just a simple open/closed switch as in years past.
