"Throttle snatch".
I've logged a thousand miles during my first week of owning this beauty and I love so many things about the bike.
Not thrilled with the throttle snatch during low speed turns. Especially when I have my wife on the back or I'm in a Patriot Guard ride.
I would prefer a mechanical solution rather than modifying my riding techniques.

Is there a tuning device other than a power commander that works well on this bike and eliminates most of that?
 
Re: After one week of owning, my one big gripe is...

I think some guys use a different throttle tube with a more gradual curve to it but I'm not sure what it called..Throttle Tamer maybe?
 
Re: After one week of owning, my one big gripe is...

I have the throttle tamer.. it did help.

For me Ivan's FCE(Fuel Cutoff Eliminaor) worked the best. Not everyone has a positive experience though, here are some reviews.
 
Re: After one week of owning, my one big gripe is...

Throttle tamer looks like an interesting solution.
Am I wrong to think this is more of a tuning issue for EPA satisfaction?
Is there a high performance module that gets rid of lean spots in the rpm curve?
 
Re: After one week of owning, my one big gripe is...

My ST1300 is a different beast since Throttle Tamer.
Much nicer at slow speeds
 
Re: After one week of owning, my one big gripe is...

I've adopted the technique of putting my first 2 fingers on the brake lever (2nd nature now) and am able to ride ANY bike at very slow speeds, even on uneven terrain, with no problems in holding a steady throttle position.
The side benefit is it gives one a quicker brake application when needed. I've never read anything on this technique, even years of MCN subscription.

I do (and have done since dirt bikes in the 60's) the same except just use the index finger. I agree you can accurately control any twist throttle with this technique.

This technique is called "riding covered", and I always do the same thing and have since my first racing school twenty five years ago.
Doesn't solve the low speed lean throttle condition.
 
You can use these to "fix" this: G2 Throttle tamer, Ivan's box, take out all the cable slack, practice enough to rewire your brain to wrist connection. These all seem to work for different riders.
 
Power Commander doesn't seem to work with the ST's......'riding covered' generally refers to the brake....
 
Ivan's FCE, and removing all throttle cable slack worked well for my ST also.

My ST, my 2000 CBR929RR, and my 2007 Honda 919 all had very sensitive throttles, as all were manufactured with "early" Honda fuel injection. I ride well enough to be an instructor for Reg Pridmore's CLASS, but the problem with the ST is the throttle itself, not a lack of throttle management skill by the rider.

I haven't tried any of the other fixes mentioned above.

Good luck on your quest to making your ST a completely satisfying bike.
 
Ivan's FCE didn't work for my '06 ST1300. It didn't remove throttle cut-off characterstic that it's designed to. Some people have had good luck with it. I ended up removing the FCE, and installing a G2 Tamer and a set of Grip Puppies, which enlarge the diameter of the grip. The combination of the two makes it much nicer, but the "snatch" is still there. It's a shame that Honda designed such an issue into the bike in an effort to lower emissions.
 
The other solution that has been used is a different fuel pressure regulator. The TurboCity 59 psi FPR has decreased the sudden power snatch at low RPM (as well as controlling my wrist better and also tightening loose throttle cables). NONE are a complete fix IMO.
 
I have the Throttle Tamer and Ivans FCE. Neither really did much for me.

The best set up is to take out most of the slack on the throttle cables and bump up the idle to 1150-1200rpm

I agree that even though Honda had a decade and a half experience with their PGM FI fuel injection in production cars the first generation of FI bikes are very touchy to initial throttle opening. I read a sidebar article recently on fuel management in the new NC700X that is designed to return very high fuel efficiency where all that Honda knows about high efficiency lean running engines does not always translate into motorcycles because cars have inertia and throttle responses that reduce abruptness or the coarseness lean mixtures can deliver at initial throttle openings.

I didn't mean to be flippant, I agree that the answer isn't just throttle management skill - it's much more and all concerning the upper half of the motorcycle - involving fine throttle, clutch, and braking skills all together. I can't even begin to know exactly what I do with which control when; overlapping throttle and braking, perhaps holding maintenance throttle at corner entry exactly one red hair above the run-lean cutoff where the injectors run extra lean or dry, etc. All I know is the problem with a snatchy throttle went away a long time ago for me and from the responses of others in similar threads it went away with time and practice for them too. The modifications also seem to help subsets of riders as well or maybe it reduces the familarization time to get "as one" with the machine.
 
Thanks again ST board for putting a name to my problem, and another hole in my wallet.

Was struggling with this clunk/jump/curse issue this week. thought it was due to an inordinate lack of skill.
 
I must have had the odd ST because my 04 never had any slow speed surging issues and could run at idle speed in 1st gear over uneven terrain as smooth as butter.
My first 'issue' and only issue was the steering felt a little light (twitchy) at highway speed.........more akin to a sport bike. But I soon learned a very light throttle grip (give the bike its' head) solved that.

Many F800 Forum subscribers have had stalling issues on our BMWs. Many have gone to a Booster Plug (like Power Commander) or aftermarket can.
Losing the CAT can be another option. I don't stall my 800ST anymore............... I've also noticed how crisp my throttle response is now and actually quieter running at steady state speeds after a (the) tune up.
That CAT is a real negative but what can be done?

Ivan's FCE made a huge difference to my 2003 ST1300 bike. Suddenly I could ride at very low speeds/throttle openings very smoothly without having to slip the clutch. Like a ST1100 in fact!
I have recently taken delivery of a brand new ST1300 and this one has much improved fuelling which is smooth and allows the engine to start working for you with just the merest whiff of throttle. So it shows Honda can do it. Another member of the UK Owners Club recently had to have his electronics replaced after a rodent infestation over the Christmas break. The work was done under an insurance claim and included replacing the ECU in the tail. Lo and behold, his 2006 bike also now has smooth fuelling at low throttle speeds. Quite why Honda do not issue a kit to update the fuelling map for earlier bikes I do not know. Perhaps it is the Japanese thing of not wishing to lose face by being seen to have messed-up.
 
My '06 ST1300 doesn't have a slow speed surge. From my understanding of the issue, when you close the throttle, the system is designed to shutoff the fuel completely until the engine rpm's drop to within idle range, then it turns the fuel back on. This is to lower the overall emissions output. Once the fuel is turned back on, the throttle is not an issue. The "snatch" occurs when you close the throttle while entering a sharp curve, and then get back on the throttle. During this scenario, the engine doesn't slow to the point where the fuel is turned back on by itself. When you get back on the throttle, the fuel is turned back on at the level where the ECU thinks it should be based on inputs from various sensors, including throttle position, and this is when the "snatch" happens. Ivan's FCE is designed to prevent the cut-off from happening. Unfortunately, the FCE doesn't work properly on all ECU versions in the ST13's. I tried three different versions on my ST1300 and the cut-off was never eliminated. Other's with '06 ST1300's have reported that it works for them. I can only assume this is because something in the ECU was changed during the production of the 2006 ST1300's.
 
You may get used to the throttle feedback.
For slow speed work the clutch friction zone also helps.

As mentioned the mechanical mod is an eccentric throttle tube cam like the throttle tamer.

The power commander isn't compatible with the st1300.
