dynojet+K&N filter in Tansalp

Has anyone got/had a dynojet kit and k&n air filter on a Transalp (or similar sort of bike)?
-Is the difference significant?
- does it affect reliability i.e. is it just one more thing that can go wrong?
- does it effect bike performance at altitude and if so is it for better or for worse?

Since I have no idea what it is I guess I don't have it on my TA.
So.... What are those things?

Pieter.

This isn't going to cause any trouble for you in terms of reliability - changing jets will only change how the bike runs, but otherwise it doesn't change things mechanically. You may be required to drill holes in your carburetor slide, but that's a very simple thing to do and also won't affect reliability.

As for the air filter, most aftermarket air filters are better than OEM air filter, and being re-usable makes aftermarkter air filters a must anyways. I don't know for sure, but I would bet this bike comes with a paper air filter that's not re-usable.

It's also probable that the bikes comes from the factory a little lean - at least a few other models from Honda come this way, and that's probably why DynoJet makes the jet kit. So if you richen the jetting a little, at high altitude performance may decrease, since at high altitude, bikes run richer.

But if you are only riding at high altitude, you'll want to tuen your jetting for those altitudes, but if you lean the jetting for high altitude, be sure to richen it back up if you go down to sea level, or else it will run very lean and you risk overheating.

These are just the problems everyone with a carbureted bike has to deal with - I have my bike jetted for sea level, and the performance doesn't decrese enough for me to worry when I go up to 9,000 feet so I never touch it.

I should also mention that if you put a better flowing air filter in and richen up the jetting, your fuel consumption will go up slightly.

hmm, some interesting comments wbagwell, what you say makes sense. Pieter, a dynojet kit basically consists of replacement fuel jets which improve the efficiency of your fuel combustion. I think it sprays the fuel in a mist which makes it burn better this combined with the air filter can give you 3 to 4 bhp gain (allegedly). When people fit a dynojet kit they also normally fit a k&n air filter as it seems to complement the dynojet. It is quite an expensive modification £75 for dynojet and £40 for air filter plus labour if you get someone to fit it for you. To really get the most out of it you need to adjust the jets to get optimum gain and to know whether you are getting optimum gain or not you need to be able to put the bike on rollers and take power readings through the rev range. The reason I asked if anyone else had done it is that I wouldn't want to pay out that sort of money unless I knew it was going to make a noticeable difference. Some people have said that sports bikes benfit more from these kits than a big trail bike , but then dynojet do make them for the Transalp as well.

The K&N for the TA is very good, but mainly for its "no need to ever replace it" quality. A great bit of kit for those of us going out of the metropoles. As for the dynojet, reports suggest it delivers very little.

If I would ever experience a lock of power with my TA I would switch to a AT i gues.
As for reliability, no problems untill now, that is 2 years and 67000km of abuse. So don't feel the need for any kit.


Oh and the tingling sound dissapeared :-)))) Getting the bike checked any way next week.
