After getting my carbs back together, motor buttoned up after valve clearance check and newly painted parts put back on. My machine is lookin GREAT, its going to be 65 degrees today an I'm going to be ready.
My bike fired right off as usual, as the temp gouge went up the bike ran worse. I tried to sync the carbs and couldn't pull good vacuum on #4. Checked for bent linkage tabs etc. nothing. I tore back through the carbs, missed a PAJ1 for a PAJ2, corrected , still ran terrible.........
I started a trouble shoot on the ignition and found coil plug wire issues on all 4 cylinders, the
little plastic two wire plug. After getting wildly varying resistance readings on the red/white wires
I had to resolder the spades on both sides of all 4 plugs, great spark but still ran like **** .....
The Forum to the rescue! I was scouring carb/ ignition posts in between brain damage breaks when I found a post about airbox boots. It hit me then that my box boot clamps were completely closing but the box felt less than snug.
I got to the bike, looked under the box and WTF! The boots were all a mushroomed mess on the
inside radius, not where you could see it when tightening the clamps. OMG I don't inspect stuff when I'm removing it or what!
Reading the post, guys were doing different things to remedy this, mine is/was to break out the Dremmel. I cut in nice deep square seats, the boots now sit deep and tight on the mouths of the carbs.
What a difference, night and day, my vacuum had been at about 3.5 @ cyl#2 and I would go around syncing from there. My meter seals down on the mouth of each velocity tube.
Now its at 6 on the meter! All the way around.
This new revelation opens a huge can of worms in the jetting department since I have been tuning the bike to a leaky boot air box. All of the little connections inside needed reconnecting too. I've only opened it to clean the panel filter once since the mod. pics
After getting the box cleaned up the bike started and synced-up great, sounds different and runs great ,Vboost is crisp like an on/off switch.
Cant wait to read the plugs and see how she's eating and breathing.
