F.Honda750xd 197 Posted January 17 Share Posted January 17 Hi all I've a 750 dct x 2018 and once the bike is warmed up and I stop at lights if I don't hold the front brake the bike slowly moves forward as if the clutch is engaging. The revs are just above 1 and just my leg power is enough to stop it and keep it stationary. Any idea what can be causing this?? Link to post
DaveM59 1,605 Posted January 17 Share Posted January 17 Tickover should be 850ish. Needs adjusting down a bit. 1 1 Link to post
DWD 62 Posted January 17 Share Posted January 17 How do you adjust the tickover speed. I thought the ECU took care of that. Sounds like it needs the clutch reset job to me. Link to post
Slowboy 20,576 Posted January 17 Share Posted January 17 (edited) from the manual: ENGINE IDLE SPEED NOTE: chapter 3-12 • Inspect the idle speed after all other engine maintenance items have been performed and are within specifications . •Before checking the idle speed, inspect the following items. - No OTC and MIL blinking - Spark plug condition (page 3-7) - Air cleaner element condition (page 3-6) The engine must be warm for accurate idle speed inspection. This system eliminates the need for manual idle speed adjustment compared to previous designs. Turn the ignition switch ON and engine stop switch"()". Start the engine and let it idle. Check the idle speed. IDLE SPEED: 1,200 ± 100 rpm If the idle speed is out of the specification, check the following: - Intake air leak or engine top-end problem (page 10-4) - Throttle operation and freeplay (page 3-4) - IACV operation (page 7-21) Edited January 17 by Slowboy 3 1 Link to post
alhendo1 3,053 Posted January 17 Share Posted January 17 I've just read a tinternet thread on dct creep and high idle....think it was a US forum....symptoms are the same as yours....in that thread they talk about water in sensors after power washing....it apparently rectifies itself after a couple of good runs.....has your bike got excessively wet recently?

F.Honda750xd 197 Posted January 18 Author Share Posted January 18 Thanks for all the imput I'll try to get the revs down a bit and also consider doing the clutch reset procedure. As for the water ingres I'd definitely rule that out as I never ride in the wet and remains under cover constantly. Cheers. 2 Link to post

As previously mentioned, 1200 + or - 100 is the spec. Link to post

Andy I wouldn’t say “never.” I’ve not heard of my dealership using anything but the correct oil. I have heard of customers insisting on an inappropriate oil because the “heard on the interwebs” (they don’t get their way), but we have preset invoices for every model of bike, appropriate bulk oils in stock, and litres on the shelf for other motorcycle brands if needed. I’m not saying we never make a mistake, but choosing the right oil is kind of a no-brainer in a dealership setting. Link to post

I think Andy's point is the DCT version having a specific need for 10W30 as opposed to non-DCT and the potential for "some" dealers to not be aware (or attentive enough) to not use their business-as-usual bulk 10W40. 1 Link to post

Oh, there are certainly dealers around here I wouldn’t trust to get it right even with their own brands of bike. And as for oil, our Honda bulk oil is GN4 10W30. Most Hondas new enough to be coming to the dealer for service use that. (I have noticed that some markets have different oil specs and availability. Honda itself has some types of oil in the UK that aren’t offered here, and I don’t think the climate differences can account for that. A mystery.) 1 Link to post
