snatchy throttle

Hi Guys

This is my first post and I hope some of you can help with a problem I have with my F4 750s. I loved riding this bike and since owning it since 2000 has always been plague with this throttle that seems to be snap shut every time you close the throttle. When you open the throttle again it is snatchy and difficult to modulate smoothness . It helped a little when I put in a power commander and removed the baffles on the standard pipes but does'nt go away or behave like any other bike( I have a couple riding smoothly on the throttle with the MV is the most demanding.)


Is there a solution for this problem or am I the only one complaining since 2000.

In spite of this I still love riding the bike. needs revs, sound fantastic( the beat 4 cylinder sound), looks great and makes the rider feel special.

would appreaciate any help that is offered.

On the left side of the bike, on throttle assembly there are two springs. Remove one of them. That may help.

Welcome aboard.

Richen up the fuelling in the low throttle opening portions of your PC table.

snatchy throttle

Hi Guys

Forgot to mentioned that the springs were already trimmed off. It helped a little but problem is still there. Based on what I heard that's how it is. It is the f4 characteristic and it cannot be tuned or solve. Some friend even suggested a misalign throttle body butterflies.

I will try to richen up the mixture a little at low rpm.

So finally did you sync it or sell it. Either way the problem disappeared?

My F4 was never snatchy (not sure what you mean by that) but I did find the TB synch to be out by 4 cm's of mercury betwen 2 & 3. I can't really say it changed anything but at least they're where they belong.

Bite me Randy, bite bite me Randy.

I got mine. Boy do I ever got mine.
