mexmex Posted May 23, 2014 Report Share Posted May 23, 2014 Hi One Cabastany Replica 2013 and the other 3.0 as well 2013. Normally we are riding at very high altitude (11,000' = 3600m) and we got a nice and clean setup for this condition. Next week we have our 1st national, which will be held in the north at 800m and I don't have any idea which jetting will work. Normally I would just try but as this is very remote place, we are flying over (shipping the bikes in truck), and I will have very little time to setup the bike if any. So any base line will be greatly appriciated! Cheers! Quote Link to comment Share on other sites More sharing options...
dadof2 Posted May 23, 2014 Report Share Posted May 23, 2014 With a drop in altitude from 3600m to 800m you can expect to richen your jetting by between 9% and 3% the exact amount depending on temperature and humidity. 1 to 2 numbers on the jet size per 1000 ft is not a bad starting point. I think Honda use to have some tables on this in their 2T MX bike manuals if you can find someone with one. Quote Link to comment Share on other sites More sharing options...
copemech Posted May 24, 2014 Report Share Posted May 24, 2014 45/125 would be standard jetting for the Kiehin bikes. As you will have no time for fine tuning it should work ok I would think. Quote Link to comment Share on other sites More sharing options...
mexmex Posted May 24, 2014 Author Report Share Posted May 24, 2014 Thanks guys! I will do 45/125 and hope for good. I might have couple of hours to play with it. Quote Link to comment Share on other sites More sharing options...
copemech Posted May 25, 2014 Report Share Posted May 25, 2014 Where is this ride in the north? Not that I intend to take a leisure drive across the border to watch! Quote Link to comment Share on other sites More sharing options...
mexmex Posted May 25, 2014 Author Report Share Posted May 25, 2014 Where is this ride in the north? Not that I intend to take a leisure drive across the border to watch! Cola de Caballo ("Horse ass" ) which is around 40 km south to Monterrey. Never been there before but the locals say its just unbeliavble with amazing ride out of the hotel.

hf28 Posted July 24, 2014 Report Share Posted July 24, 2014 What is the jetting you use at 11,000'? I am riding the UTE Cup trials next month and we start at 11,200'. I have a 2013 300 and I'm not sure what jetting to start with. Thanks Haydn Quote Link to comment Share on other sites More sharing options...
