Would i be able to fit the DNA and the stage 2 top without changing the fuel mixture and exhausts?

yes, many of them done just that but Kev has a new mod for the Tenere who will make things a lot smoother and its a cheapo mod at that so if you know what's good for you.... Ask Kev :laughing7:

i.e. clogging and simulated cost (as you stated) just thought I'd correct the statement above.. :YellowWink_VZHUX5: I have no doubt the DNA is a good product though.. |
I can vouch for the filtering quality of the DNA filters on the Tenere - I used three (one changed each day) on the Heroes-Legend rally, and no dust passed through the filters whatsoever - very impressive.
The only 'criticism' I have (and have seen reported elsewhere) is that the filters did not seat snugly against the stage II airbox lid - you were able to rotate the drum with your finger even when the lid was screwed down tight. Now this may be down to manufacturing tolerances at Yamaha (but I doubt it, as it's a one-piece moulded airbox with a metal seat attached), but just to be aware - I solved the problem by placing a large rubber O ring in the seat under the filter to lift it, and it then sealed tightly. J x ps. this message was brought to you independently, at no time has DNA sponsored me, nor have I been given the opportunity to purchase said products at anything less than full retail price. Of course, should that change, I will endeavor to be even more gushing about the product, media whore that I am... |

It is not, therefore, an inexpensive replacement job of one for one. After the filters and PC have been fitted the bike will also need to be tuned as no two engines are the same? Be prepared to part with some cash. Disclaimer; What I know about modern motorbikes is zero. This knowledge has been learned the 'hard' way, lol. My DNA set up (1 to 3) arrived yesterday and I am waiting for the PC to be delievered presently. I shall let you know how I get on after installation. My best to you and yours, Ryland. |
As Ryland explains (and for anyone else not aware) - the DNA is not just a 'replacement' for the stock Yamaha paper filter, but is a freer flowing filter - thus allows more air into the engine (together with the Stage 2 open airbox lid, significantly more air). Even though the bike is EFi and has various sensors, you cannot expect the standard ECU to compensate for the extra air as it is beyond it's typical parameters...
However, it must be said the stock ECU does seem to compensate for [i]less[i/] air rather well - typically found at high altitude (Pikes Peak peak has hald the air than you find at sea level for example) - but of course all that is going to happen there is it will run rich, rather than lean, and thus less likely to cause any lasting damage to the engine. As Ryland says, the real benefit of fitting an open airbox/free-flow filter is only in conjunction with having the fuel set up properly to match - then you can expect some noticable improvements in power and power delivery. However, it is best done with a freer flowing exhaust too, and that all adds up - ultimately, you have to consider what it is you want from this bike and the modifications? J xx |

Ownership is proving a LOT more costly and complicated than I had anticipated. It is fine to see the bike in the showroom and make the initial purchase but then there are the 'extras' and they really do add up. Insurance came as one hell of a shock! Crash bars, back box, helmet's, boots, trousers, coat's, gloves, DNA full kit and the power commander. I dare not mention the final bill? Lol, cough, choke. Service costs. I dropped her so that was more expense (my own fault). No way am I going to change the exhaust system, 2,000� for the Akrapovic! I think we have all got to find our own ceiling of expenditure, I have reached mine, in fact surpassed it! Lol Enjoyed ever second of it though. I had no idea that changing the air filter would take me where it has in terms of further purchases. I should have done a lot more home work before diving in. Expensive learning curve. I hope it will prove worth it when the bike is finally set up. Just waiting for the PC to be delievered then I will try and fit it, fail and end up paying my Yamaha garage to fit it for me! Lol Don't smoke, don't drink, don't gamble........what the heck! Ryland |
You would not like to know how much money I have put into my XT mods over the years, please don't tell my wife Ha Ha.
I still want to do a big valve head & stroker crank. |
