[QUOTE="Dinny, post: 33815, member: 2178"] I'm running a standard B rap with shadow carbs at an elevation of 5000 feet altitude, some days when it's hot the density altitude gets as high as 8000 feet. I have k&n filters on and was looking for advice of carb setup. The main jets have been reduced to 170 's and one cylinder bogs down on acceleration and it just feels flat and misses when coming onto the throttle. My thoughts are to open up the cutout on the rear slide (rear cylinder is the prob) or go with a smaller needle jet (both 106). They are both currently set on the rich side as running in but maybe I'm expecting too much running at such weather extremes as its cold in the winter so I'm dealing with large changes in heat and altitude. On a hot day it's clearly running to rich which is causing the issues. Anyone running 289's at a high altitude, if so what's your setup? Dont tell me it's just a winter bike or cold day bike...... Thanks Mark [/QUOTE]
