You must be joking for sure weeksy. You would be the only person I have ever heard say there is no gain with a stage 1 & 2 filter & fuel mod.

There is a big difference between a standard XT & a XT with a stage 1 & 2 air filter & fuel mod, dyno results below.

We have proven this so many times on the dyno, this setup works really well. Blue line a standard XT660, red line stage 1 & 2 filters with a PCIII, CCC cans.

I'm not saying the difference isn't there mate, not at all. However the feel and perception to me personally isn't really that significant.

As you know, i'm on my 2nd XTX now, this one has the same mods as the first, but with the addition of a PC3. I also rode the frist xtx in standard trim for the first few weeks of ownership.

But from a riding perspective, i just don't think they 'feel' much different at all, with or without the mods.

I feel to answer the guys question, the sprocket (2 up rear) was a cheap and effective mod more so than any of the others.

I've often seen peoples reports of "fitted this and WOW..." and i just don't get it..

That is because with all due respect, you are missing the point. The XT's have a very torquey single cyl engine which is heavily restricted from factory to comply with emissione regulations and all that bollx. Modding an XT is not for the purpose of doing 160mph on the clock, but is done so you can render the full performance which it was designed for, without the intrinsecate cats restrictors in the cans (have you ever seen a standard can cut open? Well let me tell you you couldn't fit a pen in there so much is the layout of deflectors and the space taken by the cat converter), and then there is a very choked up air box to deal with that reduces the air intake, hence fitting the DNA stage one & two and the removal of the snorkel alone makes your front wheel come up at the throttle. The gearing is another different issue, but also that factor means that the bike is designed to be powerful on low regimes and not on full pelt.

Altering the sprocket sizes might change things but the overall result would enhance one aspect and compromise another. Click on the attached excel file and then experiment with changing sprocket sizes and see what the result is in speed vs torque, then you will be able to understand what does what.

I did actually also ask for personal opinion on experienced difference with this mod, which is what weeksy provided, so thanks for that weeksy.

Please don't get me wrong, this is an open forum & all views are very welcome, I am just shocked as this is the first time I have ever heard some make this statement, there might be others who knows. I welcome all views on this topic.

I am not trying to prove who is right or wrong here, just trying to provide the facts for you nazurro.

In your defence mate, i'm not known for 'feel' on a bike LOL.

Back in the day when racing, the suspension expert would make 10 changes to the bike and i'd think "still feels the same".... ride it and lap in the exact same times.... Change it again... still the same... LOL.

Nope, i'm afraid YOU are missing my point....

To me... the bike in either stock trim or modified trim is excellent.... However i struggle to feel/tell the difference. It has nothing to do with "the airbox ...." or "big torquey single" etc. It's all to do with how the bike seems to the individual riding it.

oooook whatever floats your boat. Happy days!

The sprockets are original on my bike from new both front and rear.
When I first got the bike (new from showroom) it would lift in 1st but 2nd you had to dip the clutch and youd no chance at all in 3rd.
The extra lift it has now has come purely from the mods mentioned. I have to add though it may also be helped by it loosening up a bit?

Glad to see you've sparked a discussion nazurro :)

Snorkel removal and upping the Co are free and easily reversible modifications, so to start with why not give give them a go. These were the first things I did while awaiting the cash for my MTC exhausts and I was pleasantly surprised. Although a proportion (large or small I'm not sure?) was due to the improved induction noise as much as a real difference in power output. Be interesting to see your feedback as you do various mods. I now have Stage 1 and 2 filters and a PCIII in addition to the above mentioned.
Have fun,
