Hi All

Thanks for all the jetting information from your real world testing! Let me introduce myself: I'm a South African living happily in Scotland, and enjoying the lovely country roads here.

I've been through all of the post to help me in deciding what jets to order for my bike, a 98 KLE 500 A7. Firstly I installed a K&N air filter and the larger air intake snorkel which I managed to get from a scrap dealer on ebay. This larger snorkel made the bike hesitate hugely from 1/4 to 3/4 throttle even when accelerating slightly. So, off with the snorkel then.

I decided to order the N96J needles, and a 112 and 110 jet to work with the larger snorkel. Since then, I've chopped off the standard silencer, and mounted a 2010 KTM SXF silencer (sounds really good! 33mm outlet as opposed to 22mm standard) - this doesnt have any adverse affects with the standard jetting and small snorkel.

So, with just the K&N filter, KTM end can, and 17/46 gearing, I got over 53mpg (19km/l) yesterday on a country ride averaging about 40mph (some fast 85mph, some slow single lane)

I'll let you know how I get on when I receive the jets and refit the large snorkel. I don't really wan't to start drilling any holes, so hope that I can get the jetting right without huge increase in fuel consumption (I commute 74 miles a day).

Thanks again for all the useful info, especially mollrik and spye.

Cheers.
