3500 rpm popping and juddering help!!!

[vstrom2007]

Any ideas on why my DL1000 is popping and holding back it's around 3500 rpm and the same in any gear or speed also the near side exhaust is rich and hotter than the other side boots on air box seem OK and I'm in France so limited tools

[Gassoon]

Is there owt you've just done which might be germane? Eg, just filled up with fuel? (wrong fuel, dodgy fuel possibility, it happens).
Have you had the tank off? trapped a hose?
Big possibility its the boot come off even if it looks OK at first glance...I've heard somebody say that before on here with a 1000.

[vstrom2007]

Thanks gassoon boot are good and vacuum hoses are OK 1 exhaust is stinking of fuel and no changes just progressively getting worse and popping through airbox

[tallpaul]

It's this the dodgy ignition coil thing? The unburnt fuel from one cylinder burns in the exhaust pipe, causing it to get red hot? My memory isn't what it was.
Hope you get to the bottom of it soon.

I've got the same problem, trying to hold a constant speed in town is a nightmare. Don't think I've got exhaust problem though.

Sorry to hear you are having problems but this problem sounds very familiar with myself and other Vee owners. I had this issue when I purchased my Vee and did everything to try and resolve it, I'm not sure why but after checking everything on a completly stock machine I couldn't understand how it ran like that and eventually drew a blank....  but in the end I gave in and bought a power commander III which ironed out all running issues.
I'm not sure if your Vee is the same but mine is super sensitive to crap fuel, have you tried a fresh tank of fuel..? maybe higher octaine ..?

[Gassoon]

Hope you got to the bottom of it...search the forum for similar issues...

Or on VSRI site ...http://www.vstrom.info/Smf/index.php/topic,19059.0.html


That last bloke had the exhaust get so hot it destroyed the exhaust and his saddlebags, it was ignition coils.

...I got the call. Diagnosis - loose coil wire caused missing, dumping raw fuel into the exhaust, where it later burned and overheated the RH muffler.

 Might not be that on yours, but worth looking into...

[vstrom2007]

Bit the bullet put it into a local dealer valves checked nothing too bad there. Throttle body sync  done as apparently they were well out also wrong plugs in it?? I used the iridium crx 8 ones (I think)  as suggested on here and flea bay and going to collect in the morning hopefully cured....  update to follow

[Gassoon]

Must have got you back from France anyway  !

Wee Standard Spark plug: NGK CR8E or DENSO U24ESR-N
Wee Iridium Spark plug: NGK CR8EIX
Vee Standard Spark plug: NGK CR8EK or DENSO U24ETR

Fingers crossed!

[kirky1298]

Throttle body sync will have cured it big J.
Put standard plugs in it and throw the iridium things to feck. A spark is a spark and I don't give a feck what anyone else says.
Oh, and check they set the TPS before they balanced the TB's .
Good luck and mind let us know how it goes. Jok .

Iridiums last longer. As long as they are the correct plugs, and CR8EIX plugs are, let them be.

Correct, a platinum plug will last around 50-65 thousand miles and an iridium plug will last anywhere between 85 and 120 thousand miles. I'd love to be a fly on the wall when you try and remove the plugs after that mileage.  
What is it they say about a fool and his money ???

???

I've never had a problem. NGK spark plug threads are coated to prevent seizure. http://www.ngkplugpro.ca/content/conten ... kPlugs.pdf

[Juvecu]

You definitely don't leave iridium plugs in that long simply because they will last that long. Take them out each service where you'd normally have to change standard plugs and at least reset the gap and check that there's no damage such as cracked insulator or something.

[vstrom2007]

Collected and much much improved but needs a good run tomorrow to check. Plugs are now normal ngk ones apparently the iridium ones were a bit  shorter than the ngk ones? I'm going to check tomorrow against a old set. Anyway tsb was the main reason for popping but lucky on the mini tour I had a larger male on a 650 acting as a wind breaker and I have 2 iridium plugs for the lawn mower now as a result of the tour.

[kirky1298]

Good to hear its fixed john. I'll feckin wind breaker breaker you you cheeky monkey !!  

[vstrom2007]

Plugs were 12 mm shorter mmm

[ziggy]

Blimey well wrong possibly half the length they should be.

 

[kirky1298]

Plugs were 12 mm shorter mmm

Away you Auld fanny !!!!!   .

[vstrom2007]
