Yes, report back - I'd be interested in the result!

Can I report a massive improvement too, by adjusting the Throttle sensor, although mine went to 29 degrees, and I think for my bike this is a tad too much, as now the revs bounce up to 1800 when in neutral, and back down to 1150 when 1st is selected. Also, I noticed only this afternoon that I can't change the traction control setting, it just flashes, which the manual suggests is it thinks the throttle isn't fully closed.

But the improvement in control is like being on a different bike. While Frasers was working on mine I took out their demo, and the difference was very striking, so clearly there is some variation in how the bikes are being set up.

Anyway, I am now within 1% of being completely delighted with my bike, and that last percent is due to the panniers and top box being a bit small for longer distance touring. That said, I was at Touratech last week, and they are preparing a range of accessories for the bike, so hopefully even that will get sorted sooner or later.

I'm guessing that the Touratech bits and pieces will look something like the bikes on this site:

Coo, if a bit Mad Max for this old git! but the side cases and radiator guard look the biz! I'm starting a savings fund right now....

There's also the most common Touratech accessory.

Ah, but had you considered that some of us might be so stinking, filthy rich, that the reason we complain about the small panniers is that they aren't big enough to carry all our cash? I'd have thought that was obvious, given some of us might have bought our bikes immediately they hit the showrooms, and therefore price is clearly, um, less of a consideration, shall we say?

Of course, alternatively, we might just be complete idiots.....

Compared to some panniers the DL ones are small as some bikers look like they are on a juggernought when riding with the big boxes. For years the wife and I have managed with a top box each and these have been no adequate . You don't need to carry the kitchen sink.
After saying that since we have had the DL with the luggage we have found that they are just the job. By that I mean I do not have to think about them when filtering etc.
Also whilst on the way to Normandy recently we went through a monsoon and I had also treated this a test to see if the boxes were water tight as we had not packed any clothing into plastic bags, this allows one to get more into the boxes. And I am very pleased to say they were as dry as a bone. Result.

Damn, damn and double damn. After 130 miles with no issues, the dreaded cut out has just happened again!

I was in 1st gear, just pulled the clutch in as rolling up my driveway about to come to a stop and it sounded like a misfire then cut out.

A previous comment suggested buying the following to smooth out the jerkiness of the on/off of the throttle in low gears, which I will, but not before I have Suzuki sort the the cutting out issue.

Will update this post once its been back to the dealer for round 2....

Just picked up new tps sensor, £81 !!! Seems to have resolved the stalling and leaching

SUCCESS SUCCESS SUCCESS!!!!

Had the ECU re-mapped on Saturday at "Hilltop Tuning" just west of Leicester.

Was a 320 mile round trip for me and all I can say is not only did the bike NOT cut out or even go to cut out on the 180 mile return journey but it ran like an absolute dream!!

To sum up:
Cut outs have stopped and the bike shows no signs of wanting to cut out when shutting the throttle approaching junctions. I had 3 near cut outs on the way up to Leicester and none on the way home!

Jerkiness in lower revs has now gone (apart from the obvious engine braking which you would expect and enjoy when riding a big V twin). In comparison, previously it was like riding a tractor in anything under 3k rpm with the sudden switch like effect of the power when rolling on/off the throttle.

Power delivery is now smooth and consistent throughout each gear and an absolute pleasure to crank on the power in any gear.

As an additional bonus I have an extra 20% bhp at the rear wheel and increased torque (can't remember the torque figures as haven't got the dyno readings to hand).
1st dyno reading showed 77bhp at the rear wheel and also highlighted that the bike was running ridiculously lean under 2700rpm.
2nd dyno reading showed 90bhp at the rear wheel and much improved Air/Fuel ratio in lower revs.

For the first time in 4 months since purchasing the bike I can now say that it is an absolute joy to ride. So much so, that a 40 mile detour was in order on the return journey to extend the riding pleasure.

Have still got a massive grin on my face since Saturday and buzzing to get back out the bike.

Big thanks to Geoff at Hilltop Tuning for getting this sorted.

Sounds like you have a new bike

glad its sorted m8

Excellent. I have been thinking of taking my S10 to him.

If you take it into a dealership for servicing, make sure they don't overwrite the map with an updated version of the Suzuki one!

grimcookie · « **Reply #94 on:** July 12, 2014, 08:47:49 »

Oddbod is not alone mine is going back today with exactly the same fault, plus its losing coolant.

wunwinglow · « **Reply #95 on:** July 22, 2014, 23:53:47 »

Took mine to Hilltop today following in oddbods tyre tracks, with pretty much identical results. In fact, on the first run Geoff hopped off the bike, it was running so lean at low revs he thought the analyser sensor had fallen out of the exhaust! Excellent service, I now have the bike I always knew was lurking hidden underneath. Definitely recommended. Oh, and while you are waiting walk down the High Street to the Cob Shop for some fantastic food! Also definitely recommended!

Thanks Geoff and Ashley for a fascinating and rewarding day. And my bike sorted!

Are there any potential or definite downsides to the tuning? (More engine stress thus potentially shorter engine life, lower efficiency thus less MPG etc?)

frez · « **Reply #97 on:** July 23, 2014, 08:51:00 »

IMO, generating more power may have an impact on the lifetime of the clutch and gearbox, but it's not likely to have an impact on the engine.

OK scratch my initial comments, this gives a better explanation of fuel ratios...

wunwinglow · « **Reply #98 on:** July 23, 2014, 12:17:53 »

I think that is down to the way you ride. If the engine can produce more power at the same throttle setting, presumably you will need a lesser throttle setting to produce the same power. If most of the power is being soaked up by aerodynamic drag, especially at higher speeds, then for any given speed, you will need pretty much the same power. So you will be able to travel at the same speeds, with the engine producing the same power. Just that the throttle setting will be less, and certainly in my case, it is a WHOLE LOT smoother and refined. It just feels so much, um, happier, for want of a better word!!

To be honest, I'm taking the power/torque increases as an added bonus. Far and away the most important improvement for me is the smoothness of the engine, and the complete disappearance of the rough, nasty, 'just about to cough/fart/stall' feeling it gave before the remap. Indeed, on my little test ride I went round a roundabout on the bypass at Earl Shilton several times, lent over, 2nd gear, trying to provoke a splutter; nothing! Just smooth, consistent, controllable power. Coming in to work this morning down the M32, 5th gear, 65-70, smooth as silk, just delightful!!

I hadn't realised just how 'grumpy' the bike had been before, especially below 4000. I now have the dyno plots to show exactly why!! And the curves after the tweak are as smooth as the ride is now.

Yep, one very happy bunny!!

Just read that fuel air article, fascinating! The ratio on the initial run was off the scale lean-wise!! It only dropped below 20 at 2000, down to 16 at about 2150, back up to 20 at 2900, off the scale until 3200, then dropped back to a sensible 13 at 3900; stayed below 12.5 for the rest of the range.
