Today I adjusted my TPS. I am VERY Happy with the way it turned out.
Here is some history. 04 DL650, 6300 miles.
When I first got it, it ran perfect... throttle & engine very smooth.
Over time things got Buzzy.. I thought : OK I gotta sync the TB's ..
Yes they were out by about 12". I synced them.
Then things felt better but now I was Buzzy in a different place, on acceleration at 4, 5 and 6 thousand RPM. Buzzy in the Seat of the pants and Bars, Bike felt like it was working against itself, not that "electric" feeling.
Last week I checked the sync again, it was out a little, I adjusted.
Buzz was not going away, seems like over time it got worse.
I know everywhere you read about the TBS they also say adjust the TPS
Well I was reluctant, because I didnt really understand the process...
I read a lot of documentation on the DL-1000 but I was never 100% sure the process was the same on the DL-650.
Also, the other Strom forum and FAQ shows a process that utilizes a multimeter and checking the voltage at the TPS.
This Multimeter process is good ( I think ) but I didnt want to remove the Airbox all the way.. So I used the other method using the bikes Dealer Mode..
Here is the Tutorial I followed.. it is very good
As you can read they predict your TPS will jump to the next level at about 3000 rpm... thats where mine jumped up..
I was able to adjust mine to jump up at about 1700 RPM.
The result: Much Much Smoother acceleration. Buzz is gone.
Be warned, when you loosen and move the TPS it is EXTREMLY SENSITIVE.
Meaning, if you just breath on the TPS it is Way out of adjustment.....
So you have to take your time and be real patient... But dont give up
You can get it there.
I took it out for a test spin... Runs very very good, much smoother.
feels like it did when I first got it.
Best Regards !
