New to this forum and would like to ask about jetting for my 2005 Thruxton, Bike has jetting from sea level and now am living at 7,500 ft. and am riding up to 11,000 ft. If someone could give a baseline setting that would be great, thanks for your time. Chuck Horton. Oh and also is there a place online where I could purchase the jets?
Popular wisdom from Amal Carburettors is that if you ride between 3000ft and 6000ft then it may help to reduce main jet sizes by 5%. For every further 1000ft reduce jet sizes by about 3%. You must be able to source Keihin jets in the States but these people ship Worldwide https://www.triumphtwinpower.com/triumph-thruxton-865-jetting-kits.php
Chuck Horton Can't help with your question. But welcome to the family. Do hope you get it all sorted soon. Do drop us all a picture of the steed. Regards & Ride Safe Joe
Chuck, why not look on the US forums as there will be a lot more people who have done the tuning for those elevations. Triumph rat net ??
