Riding the wave of 86 400's

Took the recently required, stable of 86 400's up to a national forest trail system called Rampart Range here in Colorado this weekend. All I can say is how happy I am to have these two awesome left kickers!

On a side note, anyone have any good ideas on how to damper the handlebar vibration? Brother bought new bars, and he had a hard time with the vibrations.

Taper bars might help. Do your bar mounts seat into rubber bushings in the top triple? You might want to consider the switch to the earlier triple clamps that have the rubber inserts in the top triple and the taper bars for more rigidity. They have 1" diameter at the bar mounts and taper down to 7/8" at the grips.

those weighted bar ends , that rubber thing believe its called a bar snake , aluminium bars the big 1 1/8 are good but gotta find clamps for those if it seems really bad check your motor mounts slightly over size bolts no paint in them anywhere and killer tight and don't forget to check the crank bearings

have the crank balanced, and be sure jetting and ignition are right..
very true about the motor mounts, make sure they are tight and the swinger pivot is ok. the ss mounts from phil are sweet.
sometimes the cranks are out of true from the factory and sometimes they are smooth.

Anyone ever try filling your handlebars with spray foam to reduce vibration?

Does it work?

another solution would be a head stay connecting the cylinder head to the frame like the modern bikes..i would like to do this as i bet it would be a big help

big bore crank out of tolerance is most vibration whoes
even new had one that was just out of spec

I have made a head stay setup and it worked for a while until the rear swingarm/engine bolt/bushes wore out more.
The setup just hid the problem.
Husky engines aren't balanced all that well either.
Balanced my 86 WR240 and it was way out , could not believe how much I had to remove from the crank and ended up stopping early.
Must have been close because it revs like a 80 now and no vibs.

Vince at Mr Crankshaft
best and real fast, accurate and inexpensive

Not a source for rod kits though.

must send him all parts
