Impossible for both mods to be faulty as I test every mod before shipping, I will Email you the fitting tests instructions now. There must be something radically wrong with your bike if it does not respond to more fuel in the open & closed loop maps, I would advise you to remove both mods & fix the fuelling first.

I don't suspect one or both units to be faulty. I am just commenting that on my particular bike there is no perceptible difference with either mod. I have found another local dyno centre who, for �40, will hook the bike up and check the A/F ratio again and allow me to connect and disconnect the mods to actually establish both if they are working, and find what is the best fuel mod setting. I'll have to do this after my trip.

It may be that the mixture is now correct both in open and closed loop. I am just surprised that when others have posted responses like "Wow, it's like a new bike!" that I can't actually tell ANY difference at all.

As I said in my dyno thread, I am not really after performance, or even perfect smooth fuelling. I just want to find if the bike is running OK, and so far after one dyno run and fitting both mods, I am none the wiser.

By the way Kev, the second dyno operator agreed with you 100% about clamping the AIS for the A/F run, and said the previous guy was daft for doing the run without doing anything to the AIS. :)

What happened??

Hamslay could feel any difference with both mods installed, we checked both mods were working as they were designed & they were, I offered a full refund including return postage & the mods were sent back to me, they arrived back with me yesterday & I checked them myself & they are working as designed, I know they correct the A/F ratio as I Dyno test all my mods & the mods have been Dyno tested by other members quite a few time over the past few years.

This is the very first case I have ever had that the O2 controller mod & fuel mod appears to have made no difference to the fuelling what so ever according to Hamslay, never mind the mods now goes from a 100% positive feedback to 99.9%, I respect Hamslay feedback & stand by any mod I sell & life goes on.

Blimey!!! sounds like anyone of the threads you see about using better quality fuel too me it's like night and day but it's amazing how many folks can't tell the difference which could be a totally new thread because the gap in talent that you have between the front and back of Moto GP is exactly the same with road riders and that's not just talent in how fast they ride but what is going on with the bike.

I had 3 years in bike retail(never again) the look on peoples faces when you mentioned pre-load/compression/rebound :hmh:

Kev, your fuel mod TOTALLY transformed my XTX, no question!! This is my third XTX and I only wish I had discovered your mod sooner. Wierd to hear this story but hey, never say never. Thanks Kev!!!!

Wow! I knew I'd get some stick from being the only one who didn't post a glowing report of how my bike was like a new bike, but I didn't expect to be called the worst XT rider out there, or accused of having no idea that suspension was more than just a big spring with a bolt at each end.

I consider myself fully reprimanded and will return to the herd mentality at once.

:)

Well I personally do not think that a "reprimand" is in order Hamslay. Anyone with a brain wishes to improve the way their bike performs, so you are no different to the rest of us. If you do not find the improvements then you are perfectly correct to say so. Kev has acted 100% correctly also (in my opinion) by refunding the dosh. Hey, I cannot understand why your bike did not improve, but that does not mean that I should critisise you.

I think that you cannot claim to find a herd mentality here??

If I were you I would now take my bike to a decent Yamaha dealer who know what they are doing and ask them to sort out the bike. For instance Brian at Alf England can help I am sure. Good luck!!!!

Hamslay I have to say you have been treated fairily and with respect, you probably don't know but one of my painful chores, running this forum is to be a little bit like Big Brother and while I have kept away from this thread because it was handled professionally by Kev, I have read every sentence, analized all opinions, and was also in copy of the private mail that Kev sent you in regards to this matter.

I can see from the outside looking in that your feedback has been accepted as fairily as you gave it, we can only put it down to mystery as to why your bike did not respond to the fuelling mod nor the 02 eliminator mod. However you were not held as an heretic and I would wish other not to contrast Hamslay's opinions into believing it was all in his head because you and I we don't know what gremlins are causing his bike not to react positively to the Mods.

I have been in this forum from it's early days when it had a different name and was run on a Yahoo email group, since 2004 when the bike was first launched and I am aware as well as Kev is, that not two of these bikes are behaving similarly, if they did the Kev Mod would not have a controller pot that goes from min to max but just an on / off switch. And by the same token a Power commander would come pre-programmed without the need for a dedicated map. And also one map might work for a bike and not another and this similar issue does not only happen with Yamaha, but also with Aprilia, etc do you know that Kev makes a mod also for the Aprilia bikes? and KTM's? And other brands we might care to mention?

The issue with the 02 controller and ECU bad fuelling extends to a lot of modern bikes, not just the XT's

So in conclusion, I want to say that I really hate to lock threads because it looks as if we want to make a cover up of the situation, WE are not at fault nor is Kev or Hamslay.

So this thread remains open, Hmslay was issued with a refund so the matter between him and Kev are closed, I don't see the need for further discussion and bickering, I hope that from now if you really need to add anything worthy to this thread that you do it in a fashion where it is understood that the fault must not be pointed at either Hamslay, Kev or others.

Cheers!

Now lets get back to normality.

Well said!!! I would just like to know if and when he gets his bike sorted out, what was the root of his problem. Thanks guys!!!
