Rough Idle after TPS and ISCV adjustment, Please Advise

[DanielB]

I am far from a mechanic...just been learning along the way...

My bike (2002 Speed Triple) had a rough idle, and after various adjustments and investigations...it was replacing all/any vacuum hoses that totally transformed the bike (for the better).

I've not delved towards the inards of my new to me 2010 Tiger 1050, but on the assumption it may have vacuum hoses somewhere....I'd suggest checking them all over. 

Bear in mind cracks and splits may not be obvious...you may need to actually blow through them (with a finger over one end) to see if they hold pressure...

Mine were generally cracked and in poor state after 20 years.

I replaced them with nice orange and red vacuum grade silicone hose (pretty cheap) and absolutely perfect,  off the www. 

If it's similar to the 955 triple i had, there's 3 hoses from the fuel rail to airbox, and one from the airbox (I think) to the ECU.

Just sayin' could be as simple as this!

Good luck.

If you think your having a vacuum leak or boots not seated correctly. Carb cleaner is your tool.  SHORT busts at each suspected connection. Once you find it the idle will change.  Hearing a leak while running is next to impossible.

May have missed it, all cylinders or ONE.  InfraRed handheld will be a huge benefit.  Coil issue move all to right, right one far left. 
Next round, injectors. After proving the boots are seated.

While on bike a light coat of silicone spray on a towel, wipe the throttle bodies and the boots. Slowly get one side in, I do rear first lean over and insure they go in nicely. Make put in line with final placement position and holding the end. Put your weight into it and FEEL it solidly mate. ALL boots will go up the bodies same amount all sides. Take minute and make sure it's done. 
Also the Map sensor hose has shot many in the foot. 

Bonus once done with the Temp gun, I leave it in the kitchen to check temps of grease, water  to see if close to boil or ready to fry. Nice to make sure fry oil doesn't get below 350.

Thank you DanielB and Indy for the suggestions. I will go ahead and try those when I have some time next week to overlook everything again. Unfortunately I've been having to drive my car due to how hot it's getting in my area. Will keep you gentlemen and this thread updated once I make some progress. Cheers!

Hey all,

Just an update since it's been about 2 months since the last post on this thread. I figured I should update in case anyone else experiences the issue.

What seems to have resolved my idling issue is draining the tank of all it's gas and added an entire 16oz bottle of Lucas Oil Deep Clean Fuel System Cleaner and sticking with reliable gas companies. So far so good and she has been performing beautifully.

Thanks for everyone's help here and I couldn't have done it without all of you.

FYI: not sure if this is part of the issue but you may be doing the adaption wrong.

"Also clicked “Reset Adaptations” after the adjustment and let it run for 12minutes after the fans kicked in"

On my Tiger Sport the bike needs to be warmed up properly (fan kicks in) before doing the reset adaptions in Tune ECU and then that's it.
You don't need to run it for 12 mins after the fans kick in, unless you are doing a manual adaption.
Just don't touch the throttle at all during the procedure until you have restarted the bike.
