Wanted: WR450 Jetting Table based on experience
Posted March 09, 2003 - 10:59 AM
Experience with the tried and tested, trial and error approach
There are so many threads, so many questions and so many differing combinations, choosing the right jetting for our bikes is a challenge to say the least.
The 450 carb is so much more refined without needing the BK Mod, Taffy Mod etc etc the jetting needed should be getting more and more standard.
Motoman did a great job for the 426, I wonder if someone has all the info in a spreadsheet or similar they would like to share on the 450?
Manufacturers specs only go so far based on the discussions already held here on TT .......

these come with 160 Main and 48 Pilot, which so far seems to be right for the guys at sea level.
When I put my Thunder Alley on, I went up to a 165 Main and left everything else stock
also keeping in mind that our bikes come with a richer needle than the US models
If you use this as an inital starting point you will Ok
If I need to change I will substitute my numbers in Motomans jetting chart which is probably very close to being on the Button.
When is your bike due?
