Booster Plug

Hello All,

I currently own a 2017 DL1000 and I'm on a mission to reduce the harsh engine braking when decelerating. The throttle has been overly snatchy from new and with the addition of a G2 Throttle Tamer it has helped enough for me to tolerate this problem when riding solo. However, when riding 2 up, the effort required to finely control throttle openings/closings and the amount of clutch slipping required to keep the ride smooth is ridiculous. The overly strong engine braking with the smallest throttle close when decelerating feels even worse with a pillion. I'm looking for a fix and a bit cautious of getting the ECU flashed while the bike is under warranty. The Booster Plug looks promising and I'm just looking for some honest feedback into how effective it is at sorting the issues I've raised, especially with the 2017 DL1000's onwards. Your thoughts appreciated!

Thanks in advance,

I have a 2018 and never felt the throttle was snatchy at all. In fact I think it's one of the more tame and smoother throttles I've had.

I'm a big fan of the BoosterPlug. You can find some previous posts by me and others.
The short answer, from me, is do it. Don't accept any cheaper alternatives.

It turned my V2 into the bike I was hoping I had bought.

I had the booster plug, made a very small difference and was having high fuel consumption in cold weather.

Since I flashed the ECU (Woolich Racing) and turn off the fuel cut on decel, it's another bike. On my daily commute I spend 60% of the time in 1st and 2nd because of the traffic and couldn't stand the decel on this bike. The throttle tamer took care of the acceleration part, but still have an issue when sitting in traffic for a few minutes the clutch friction zone get very narrow, making slow speed acceleration more challenging. I need to test different oil brand/grade to see if it help, but maybe your 2up riding make the oil run a bit hotter and you have a similar issue?

Bully,

Check out this thread.

https://www.stromtrooper.com/dl1000a...ottle-off.html

My bike had a lot of compression braking, snappy/abrupt response throttle at partial openings at low rpm- almost obnoxious, but yet at the same time, the engine didn't pull well at lower (below 3k) rpm.

After I adjusted the TPS per the discussion in the reference thread, my engine runs much better. Less compression braking, substantially less snappy throttle at lower rpm, smoother roll on throttle response at lower rpm, chugs down low much better, etc., and it also seems to rev out better too (which seems like a coincidence?). As an unexpected bonus, it shifts better between 1st and 2nd gear- must be something related to the lesser compression braking or smoother engine running. I never would have expected such a slight TPS change would be this substantial change. I've adjusted TPS on Yam dirt bikes in the past, but it didn't change much if anything.

Anyway, check your TPS per the instructions in the thread. It's easy to check your bike's setting, and the adjustment isn't a very difficult task.

Hope this helps.

Thatís one of the things I loved about this bike. I use engine braking. When I had the complimentary ecu recall done the engine braking was extremely diminished. I was furious. I would say it was cut by 50%. The only thing they could do to change was put the old ecu back in. I didnít want to go back to the ďstallingĒ issue so I had to live with it.

Maybe take a look at your ecu and see if you somehow ended up with a left over.

I also just put some Shinko 804/805ís on and the engine braking has diminished even more. I donít think itís an ecu result, I think itís the soft compound and heavy knobby doing it. I am now kicking down 2 gears to brake. So this might be an option for softening the engine braking for you if you can tolerate bias tires.

I fitted and custom tuned a PCFC along with a throttle tamer so I have no snatch but I found for smoother ride especially two up I don't back the throttle off between gear changes.

Sorry, original comment was for the wrong bike.

If you're not living on the edge, you're taking up too much space.
