issues after dyno tune. ir temp gun readings. hot jugs switch.
one year ago I buy a new 13 road king cvo. stage one with screamin eagle super tuner pro. vance and hines Power Duals head pipes. super trap mufflers.
when new I had dealer install this stage one. never had an issue with the canned tune from the original dealer.
I go to another dealer for a dyno tune. now the bike at idle, shuts off a cylinder and runs rough (limp mode?). it happens on cool days driving around town with no traffic and no stop and go riding.
I use my ir temp gun and find the temp near the spark plug is 315 front, 265 rear. the front head pipe glows red. the rear runs about 50 degrees cooler.
I take it back to the dealer/dyno shop and they make adjustments.
after the dealer adjustment, the cylinder temps are reversed with the rear now running 40 to 50 degrees cooler than the front. 265 front and the rear cylinder saw 350 degrees just cruising around country roads. the bike went into limp mode again but with less frequency than before.
why the 50 degree difference between cylinders?
why did the front first run hotter, then after adjustments the rear now runs hotter?
whats going on?
best regards
