The bike is back from the workshop and with 5 extra ponies and a little increase in torque.

The mechanic told me that I could gain even more is the exhaust system is replaced to get rid of the catalytic convertors in the extractors or something like that.

The KLE has 3 cats and restrict the bike a lot but I decided that I had already eliminated some restriction and don't want to increase the emisions for a little extra power, at the end of the day it is not a race bike so no need for it.

The DNA filter went in and the airbox was modified, so the little snorkel intake was taken out of the box and new holes were drilled at the back of the box too. As many may know by now, K&N doesn't make and specific kit for the KLE but DNA does and they have very good reviews.

The first run in the dyno indicated that the bike was running too rich, maybe because of the premium unleaded (98+RON).So after fine tuning the carb the 134 jets went in but it went rich again. Probably because of the restrictors and because the dynokit was designed to be used in conjuction with the K&N universal kit and regular unleaded. So he tried 130 and finally settled for 126 after asking me if I wanted to keep running the bike on premium or change to regular. I rather using premiun because I had bad luck with getting bad batches of regular that made my car run like crap in a couple of occasions. But if you are running on normal unleaded the 130 are good if you keep your stock exhaust or 134 for derestricted exhaust and mufflers and unversal K&N air filters. Remember that this Dynojet kit was designed in the 90s when the emission laws weren't as tight as they are nowdays and it hasn't been updated since then due to the fact that they don't get the newer model KLE in the USA. This is the reason why the kit is sold online as 1991-1998 and for European models only.

So here is the dynorun sheet with before and after:

Before in blue with stock airbox and filter and carb. Only staintune pipe in it.

After in red with DNA air filter, modified airbox to improve airflow, 126 Main jets and the staintune pipe


My mechanic also ran the bike without the muffler restrictor at the end of the staintune exhaust and it increased the noise a lot but the gain in power was almost non existent. It was very much the same graph but going rich again at the high end of the revs range. So if I take the restrictor out it will be to piss the neighbours off or to interrupt the mobile phone conversation of some stupid drivers
