Sounds about right, what's your concern?

"without lifting the tank" ?! RTFM - Lift and support the fuel tank (page 3-6)
"Mine (DLC) was wrapped in insulation tape" ?! Sounds as if someone had a little modbodge going on there.

That's a reassuringly expensive jumper cable, especially when you should be lifting the petrol tank as part of the 8,000 mile service anyway and what if it gets inadvertently switched and shorts the SCS line to chassis ground while running or attempting to run the engine will there be anything more than a false MIL?

Speaking of the MIL and getting back on topic what stored DTC's did you retrieve?

Oh yes, thanks for the advice, this is great. Will definitely have one installed. Can't imagine having to take off all the fairings and lift the tank every time I need to read the codes. Cheers 🙏

If it sounds right that's good. It doesn't sound smooth, if you know what I mean, so my thought was maybe there was something wrong on low revs. Possibly a misfire. Other bikes I had, mind you a 125cc and 500cc (or whatever the CBX has) sounded smoother on idling. My rev counter is moving ever so slightly when idling. Just wanting to check if this is normal. If it isn't then it might be related. I'm just guessing here though.

I've not done the codes just yet, back to work this week, if I don't manage before I'll have a go next weekend and probably kill two birds with one stone and get a USB cable hooked up to the battery.

Time to get down and dirty and check those codes. If I was a gambling man I'd suspect a fuel or ignition systems fault to be the root cause of a rough idle. When lifting the petrol tank to check the codes check for any inlet air leaks while you're there.

Did someone mention that this was Phild's old SC64 (VO62NZU) the one with the failed exhaust servo? If so I'm wondering... have a read here

The downside of taking on a low mileage motorcycle that's barely turned a wheel since pre-Covid times, 4 years?

Yep, this is my bike. I've looked at the post linked, I guess it could've gone bad again. I'll read the codes to see if this is related, and troubleshoot from there. Thanks for the pointers!

I replaced the original exhaust on my Mk2 with an aftermarket one, removed the servo motor and used a Healtech servo eliminator plug (Exhaust Servo Eliminator (ESE) - ESE-H02). Worked a treat.

I also removed the servo motor bracket and the counter-balance weight plate on the opposite side of the exhaust.

If you still have the stock exhaust you would probably want to check that the exhaust valve is remaining in the fully open position. (this is just a wild guess though).

I'm still on stock, I might want to replace it anyway. I'll check if the valve is fully open too, worth a look.

Which one you got and how does it sound?

I also ordered a bottle of Redex Fuel System Cleaner, it won't hurt to try.

I fitted a FUEL exhaust and I posted pics and videos with sound in one of my previous threads:

It is better to listen to the sound on a PC with speakers or on the phone with headphones in order to hear the bass.

That sound's pretty sweet. I'm tempted to get one now :)

I took off probably more parts of the bike than I had to to access the DTC, but it was fun. I've never done this before.

I got 3 long and 5 short flashes, which is 35, which I believe is EGCV malfunction. Exhaust control valve :)
