Now I understand it's just the nature of the beast but is there anyway to keep the throttle from being so twitchy? I would love to have a just a tiny bit of play
You might try loosening one of the throttle return springs on the left side of the bike. Many times this ameliorates the problem. A 39 tooth sprocket sometimes helps. Finally, a trip to the dyno or a good tuner should solve it.
I recently got all the recommended twitchy throttle fixes done: PCIII, dynotuning to smooth out fueling, new plugs, TPS adjusted, left throttle spring removed. And there has been a definite improvement in throttle feel... it improved from terrifying to merely frightening. It is still pretty nervy rolling onto the throttle mid-corner in the lower gears. The upshot is that the throttle gets easier to modulate with practice, but the first few rides of the season can be pretty nerve racking.
I found my 750 the same when i got it so, as CAG says, take off a throttle return spring, I then fitted a pc111 & had it set up on the dyno-
Then finally, fitted a Ducati 998 throttle and ducati grips, this turns the long reach Mv unit into a quick action throttle- it also dispenses with the unnecessary Mv 2 throttle cables in favour of just 1 so it's far neater
Results are great, no more snatchy go go juice and 6bhp more
as above said but the f4 1000 already has a quick action throttle of sorts
i looked at fitting an r6 one but the twist amount was the same as my 1000 so never bothered
oh i'm bad for not reading
as twat face merito says no q a just put a 1000 one on
i mean why o why would you buy an mv then fit ducati throttles to it lol
next thing youll know you want it to sound like a duke
Did you do a "Search"???. Microtech ECU from forum sponsor Xbikes. Not sure if they do one for the Euro 2 models yet, but another quick search will answer
It's a 2000 f4 750, don't think Chris has one for them.
I actually ended up hooking the right throttle spring back up, I kinda liked it. Plus, you shouldn't be rolling on the throttle from nothing mid corner anyway :stickpoke
I found you kinda pick up the fine muscle control over riding it more, works for me anyway :f4: :thewife:
Also had Chris fit the Microtec ECU to my 750 F4 and what a difference, It is now a lot faster on the revs and the riding experience has improved a 100%. There was a horse power gain on my bike from the PC3 of about 6 HP but I believe that the gain was irrelevent when compared to the improved rideability. Money well spent. Glenn
Some of the first models had there throttle bodies completly replaced for play in the axle.
Check the linearity of the TPS resistence (specially in the beginning).
On my 750 I had tot turn the TPS a little and reset the mapping to initial value to get it smooth. (Ultimap Eprom http://www.protwins.co.uk/Ultimap/ultimap_eproms.html)

My 750s is an 02 so I'd guess maybe smoother than that but even so it was horrifically snatchy, the pc111 sorted it and a good hours dyno time, worth every penny though...
Iv now got a rare corse chip to put in the ecu and yup... Yet more dyno time :wtf:
Its been said a thousand times already, MV Corse Chip + PC3 is nearly the same price as a Microtech ECU, only Microtech ECU has litteraly maximum 100% customizable everything. Plus you don't have to carry a black PC3 box around and a load of extra wires to your injectors and TPS.
Either live with stock, or go replacement ECU, PC3 is good for extra power, but you are asking to solve your throttle problems, and the Microtech is the solution to those problems, not a PC.

Does the suggested fixes also work for the 1000 Senna?
My throttle is doing the same thing, but Trooper Lu's guys think the bush in the throttle body linkage has gone off and needs to be replaced. The bike also has a PCIII, but is running rich on # 4 cylinder.
I have had it on the dyno 3 times and its has come back in different states of tune each time - from crap to workable.
Any suggestions on a good dyno person in Sydney? TL use some guy in Chipping Norton for their work but he is A$330.00 for as long as it takes to get it right.

Microtech works. Xbikes will send it with a map for your senna, or you can take it to a place in Port stephens who will custom map the mirotech and sort any inevitable little probs that need a tweak (idle speed, TPS, and unforseen probs). Honestly, I had the PC and the Microtech. While I'm in no way bashing the PC, I have to say for sorting out throttle response, the Microtech is a one-stop shop. And it'll sort out your rich cylinder too without even breaking a sweat. And I didn't just fit a PC, I specifically had the MV specialist play around with the TPS and throttle cable and fit the PC all with the same goal of changing throttle response. Failed for me.
Its' worth posting a thread in the Xbikes site sponsor section to get the name of that approved garage at Port Stephens.
The 16m can be programmed how ever you want just like the Microtec but this would be bespoke and for the most of you, fixed.
With the Microtec and the communication lead you can change the settings every day if thats what you need.
If you have the later ecu then as Squib says the Programmable Microtec is the only answer - otherwise you have a choice
I did start a conversation with Microtech many months ago but it fell over as I didn't get replies from them on my questions.
I think I will try to give the throttle fixes and PCIII one last try and if it still doesn't work I may just leave it as it is. I am seriously considering selling the bike later this year, so getting it sorted by way of further investment is only an option if I decide to keep it.

If your not going the microtec route, I can sort out a better fuel and ignition map.
You probably won't need the PC either.
PM me if it's still rubbish

Whats the score with the Ignition map in relation to fuelling? I am getting the bike Dynoed with Xbikes (I know about the Microtec, but unfortunately dont have a grand to throw at her at the moment ) at the beginning of June, with a view to ensuring its mapped correctly for an MWR filter and the silmoto's, and also to help resolve the throttle issues at the bottom end.
I assume that if I had the map done, then the ignition maps were changed, that it would screw the fuelling up? Are they as finicky between bikes as the fuel maps are, or is it the case that a standard ignition map can be used across multiple bikes?

It would be better to get the bike dynoed after the ignition has been sorted if you want it perfect.....
A good base ignition map + bespoke fueling is was you need.
I've been looking at your maps, what issues are you trying to resolve ? throttle position / rpms ?
Well it went on the Dyno. It now feels like whole new bike. The throttle doesn't feel like a light switch anymore.
