Hi guys.. another problem with my monster 620ie... Today i was riding when suddenly it lost power... riding about 2000 rpm.. pulling full gas and monster goes like it has not fuel... it is going like with one cylinder... I do not know how to explain it... I've checked spark plugs.. they have nice color... tank full... battery loaded... do not know what to do?? help
When was the last time you changed your fuel filter?
I had similar issues in past and ended up changing fuel filter and had a loose spark plug. Good luck
I have not change fuel filter yet... going to order some... and spark plugs too

How many miles?
38000 km... but I am owner from 32000 km...
If you didn't get any maintenance records then I'd change the filter ASAP.
so.. today i've changed spark plugs... I used Denso... started it up and it goes like with one and a half cylinder.. whed i disconnet upper spark plug while engine is idling, it changes sound but keep running... when i disconnect horizontal engine stops... I do not think its fuel filter.. ordered one yesterday.. going to change it tommorow... but have anyone idea what esle can it be??
Like ab said...he had a plug wire issue.
You should check those connections, both at the coil end and the cap end.
If the connections are good, you could try swapping coils.
First do a compression or (better) leak down test to confirm the engine is good. Compression good? Swap the coils from the horizontal cylinder to the vertical cylinder and see if the vertical cylinder now stops. Do the same with the ignition wires and spark plug caps. No difference? Could be a fuel injector. Oh, and change the damn fuel filter [bang] [bang] [bang] it is a maintenance part and should be changed anyway. Also go for a ride, hit the kill switch and coast to the side of the road. Remove the spark plugs, take good photos and post. If there is a good repair shop near you it might be worth it to bring the bike to them.
leak down test?? it started suddenly..moto had lot of power before... I do not think it has bad compression... I will change the fuel filter tommorow and try to swap coils too... now when I start it and pul the gas just to 3500rpm, it shots to exhaust..

:D I 've googled it just after you posted it...
so guys.. today I swapped coils.. without result.. the same problem as before... vertical cylinder does the trouble?? what else to check??? try to swap injector, to know if there's a problem??
Yup.
Although it does sound like a loose wire based on the onset description.
but loose wire where??? wires to coil or to injector??
I got the same bike with the same problem. I changed fuel filter about 3 months ago, added some air to my rear tire, which helped. I come to the conclusion that its the throttle body setting, as well as a 3 year old battery, main chain adjustment. I was going to adjust my chain, put a new battery in and try another set of coils.
I've been trying to figure this out now for months. Sometimes it seems like I have low compression, I have major oil mist around the top of engine. And sometimes my bike when I start it will make this weird noise reminding me of the starter motor grinding. When I turn the key and the engine starts to turn there's this noise that sounds like something is over running, it's real hard to explain. I get a backfire pop from under the tank on occasion. There's 27K on the engine. Any suggestions would be helpful. 8)

Could be either. Or not. It is just that the sudden onset sounds like something just vibrated loose somewhere. It happens as the miles pile up.
what about damaged valves??? I have heard that sport Exhaust can cause that..

A leak down test will determine if there is an engine problem.
I've just swapped injector and suddenly the horizontal cylinder does the problem... so there will be problem with injector... [thumbsup]
Is it repairable or is needed to buy new one???
It's possible the injector is stuck. They can be cleaned - though DIY cleaning is probably not worth the effort as equipped shops (in the us) charge between $12 and $15 per injector - and they will have better gear than any home cleaning set up as well as a flow test machine.
So have them cleaned - be sure to mark the trouble one in some way and bring it to the attention of the shop. if cleaning/pro service will not suffice then you will probably have to buy a new injector set
do I have to buy whole set or just one injector??

Usually it is best to purchase both, if you are in the US or not, contact Chris @ ca-cycleworks, he is a forum sponsor , and he will sell you a "match flow set" of injectors
I am from slovakia... I can buy one injector from crashe M620... I put my injector to brake cleaner... maybe it will help... [roll]... how to clean it at home??? can it be dismount somehow??
You could run some Techron though the system. i worked for me!
Butt then again, it sounds like the wiring to the injector. you need to check the spray pattern from the injector before replacing parts.
You won't clean it at home. If fuel goes through the injector at all Techron is worth a try, follow directions, to strong is no good. http://www.chevronwithtechron.com/products/fuel-additives.aspx (http://www.chevronwithtechron.com/products/fuel-additives.aspx) no idea of availability where you live.

Since injectors were swapped wiring is eliminated.
I just bought two new injectors from CA cycle works. The reason was I bought a bike that had sat for many years and the fuel rail that sits on top of the injector was totally corroded.
If you want my old injectors, you can have them. I KNOW one of them works, but the other was blocked from working. I live in Texas though so it might just be better to get yours cleaned than ship them from here.

No Techron in Slovakia, maybe this, https://www.motul.com/sv/en/products/98?f%5Bapplication%5D=143&f%5Brange%5D=21 (https://www.motul.com/sv/en/products/98?f%5Bapplication%5D=143&f%5Brange%5D=21)
So guys.. before buying nwe injector I decided to try some injector cleaner.. So I put my bike back together... My injector has been 2 days in brake cleaner... when I start it up it sounds great.. i was for a test ride and it pulls like before... [bow_down] .. really happy about it... now I can [Dolph] [Dolph] [Dolph] ... preventively I will use valvoline injector cleaner to fuel... thanks a lot for your help
Yay! Congrats on a simple effective fix! Just don't use the cleaner too much!
so guys.. I am back... today I was for a ride.. when and open full throttle monster goes like a hell just to 6000 rpm... than it stops pulling and starts shooting to exhaust... spark plugs are white... ???
Did you change the fuel filter yet?
of course... changed fule filter, spark plugs too..
today gonna do TPS reset & synchro... will see the result..
so TPS reset done... "0" was on the right place.. but throtle body was set to 1,8°.. so I set it to 2,7°.. going for a test ride... will see..
so nothing new... monster still does the trouble... to 4500 rpm it pulls normaly.. but than it lost power and start shooting to exhaust... spark plugs white..

It would seem a
too lean condition, from your comment "spark plugs white" . . . do you have a performance air filter? do you have performance exhaust? if so, try setting your trim around 23 . . .
For setting your TBs, did you follow this procedure, http://www.bikeboy.org/ducati2vthrottleb.html (http://www.bikeboy.org/ducati2vthrottleb.html) ?
Why am I asking you this? I have been there, in the same situation as you . . . long time ago
original filter... termignoni slipons... before worked well with these.. yes.. I followed that procedure... how did you solve that situation??

Again, what is your trim setting? with OEM filter and Termis, you are "letting go" too much air and not letting enough in, but, your popping is from a lean condition, you need to check your trim setting and if you get/have access to an exhaust gas analyzer, your CO should be at or around 3.5%~4.5%; you have to check each cylinder individually and then set a 'compromise setting', that's how I solved it . . trim set at 23 and CO@4.0%
now, how old/dirty is the air filter? do you have the 'open top' airbox?
I sent you a link to a tool, have taken a look at it? You need such a tool if you want to work on your bike yourself.
air filter is a year old looks like new.. i have original airbox... i have my own diagnostic tool... I have put termis on the beggining of season and it was good for a half of the year.. and suddenly it's going lean??? trimm set at 22.. as stock...

bring the trim to 23 . . . you can always take it back . . .
Why, because of this statement,

<snip>... to 4500 rpm it pulls normaly.. but than it lost power and start shooting to exhaust... spark plugs white..
it pulls to 4500Rpm OK and then looses power and has 'white plugs' like the one in the image?
(http://www.mgexp.com/phile/40/128016/spark_plug.jpg)' . . . that is lean; but, shooting through the exhaust would "tell" is too rich !!! and that it's burning "not burned AF mixture within the exhaust" . . . ???
now, check all exhaust pipes connections for them to be tight
so will set it to 23 tommorow... and check the exhaust... will post the result... thanks a lot..
exhaust connections tight.... trim set to 23...cleaned gas tank, fuel pump... checke all of the fuel hoses.. nothing helped... always loosing power and shooting to exhausts...
Do you smell gasoline? Like if mixture was to rich? Have you rechecked the internal tank connections
A long time ago this happened to me, in my car, before I had the Monster and the fuel pressure regulator was at fault, if you have a plastic tank, it is inside the tank as part of the fuel pump/level sender unit. This is the only other thing I can think of.
of course.. I've checked every single hose.. all tight... yes, I smell gasoline like with rich mixture...
You have been battling this problem for about 3 weeks now. It might be time to get the bike to a good shop. Riding the bike in this condition is not good for either you or the bike. Assuming the engine is in good mechanical condition (big assumption if you did not do a compression or cylinder leak down test or check valve adjustment and timing) I suspect you have low fuel pump out, clogged injectors or both. First step would be to test fuel pump pressure, then injector spray volume and pattern, which, IMO, is not something for a do it yourselfer since you need some pricy equipment and finely atomized gasoline from the injectors is extremely flammable. Actually, first step should be to scan for codes and get readings from an exhaust gas analyzer, preferably on a dyno.
