Carb sync

Postby foots » Thu Apr 24, 2014 2:04 pm



I've got my new Morgan Carbtune Pro and would like to do a carb sync on my dad's 87 Aspencade. The bike has fairly new plugs, air filter, fresh oil, ect... and is running pretty darn good. I am able to get to the left side adjustment screw with no problem but the right side is a different story. Am I correct in assuming that I'll have to remove the lower fairing to get access to the right side carb adjustment screws? If I do have to remove the lower fairing, are there any hidden screws or the like I need to know about? Thanks in advance for any assistance.

I don't recall having to remove the plastic on my interstate,perhaps the aspy is different.
Also,the right side only has one "adjustment"screw.Right between the carbs.
Remember the sequence.Balance the right side first,then the left side and finally left to right.
All the time trying to keep the rpm near 1000 RPM.
This should be the final setting point.all carbs balanced at 1000 RPM and then idle it back down a touch.8-9 hundred.
Don't be afraid to preset the slow speed jets before the sync either and then after the sync.

Thanks for the advice Virgilmobile. The Aspy is indeed different in that it has fresh air vents on the lower portion of the fairing, which is what is blocking access to the right side carbs. This fairing seems to be a giant jigsaw puzzle.
