S90: Getting Back in the Groove

Took a five-month break while life's other priorities ate up time and money.  To cap it off, the garage storage closet got broken into a couple weeks ago. 

The thief made off with my Dremel, the Makita drill, the Unibit step bit, my valve compressor tool, and the white canvas tool bag.  Bastard!

Today I was basically just trying to get my head back into the bike.  I pulled out all my tools and boxes and sorted through everything.

I wiped down the S90 with WD40 and disassembled the top end.  The only new thing was that I removed the fork bolts for the first time, and was greeted with bright orange rust powder.  Didn't have any replacement bolts that fit (8x32) so I just oiled up the old ones and put them back in for now.

CM91: Alternator

Wanted to compare the alternator in the S90 with the one in the CM91, and realized that I'd never actually opened up the CM91's alternator cover.  There were 2 frozen screws, but they got re-slotted and one whack with the Lisle did the trick.

Stopped short of actually removing the alternator since I have to use the clutch tool to hold it in place so I can turn the bolt.

Worth noting, the CM91's alternator is stamped "CS90".  The S90's is stamped "CT90".

S90: Cast Coat Aluminum Cont.

More rattle can work with Dupli-Color Cast Coat Aluminum.

S90: Cast Coat Aluminum Paint

Finally found a good engine paint that just mimics good clean metal: Dupli-Color DE1650 Cast Coat Aluminum.  I painted part of the chain cover on the CM91 along with the head cover on the S90.  Very happy with the results.

Some Before and After on the CM91's chain cover.

 

And the S90's head cover.

S90: Gas Tank Mount Mod

Problem:  The rubber gas tank mounts would push the tank too far to the rear, which then pushed the seat back too far, which meant that the seat bolts couldn't reach the mounting holes.

Solution:  Dremel out some material from the inside of the mount so that the tank is able to ride a bit more forward.  Removing about half the width allowed the seat to fit while still providing enough rubber to keep the tank snug on the frame mounts.

S90: Engine Paint Test

Testing out some VHT brand engine paint in Aluminum Silver.  The paint does have some metallic flakes that gives it some real pop, but I think it's a little too bluish in color to work for a vintage look.

Took this shot for a visual comparison.

S90: Unchained

Was just in the mood to Dremel, so the chain came off.  Had to grind down the pegs on the master link as I believe the PO mushroomed them to make sure the plate never came off.  I counted 51 links including the master.
