89 PC (New to Me)
Written by spacetiger_j... on 8/15/2012 at 10:40 am

Great post Def, you have completed a LOT of work - post some pics to highlight
the total work completed.

Couple of comments in reference to your handling comments:
1. what weight fork oil did you choose?
2. Have you set you initial preload on the front? what size spacer did you use
(and what was your riding weight?)

If you are willing to experiment a bit to improve handling, you can make some
small adjustments AFTER you have set the front and rear preload for your riding
weight. Essentially, you can slide up the fork in the triple tree no more than
7-8mm (~0.25"). This will reduce the 28 degree rake a few degrees and shorten
the trail. You will notice the bike has a more responsive feel.

certainly kept me busy for the last couple of months including a steep (but
enjoyable) learning curve.Here is a list of what I did to my PC.(Looks like a
tune-up gone wild, actually):-)

re-sealed valve covers, replaced the clutch cover gasket, water-pipe o-rings,
and carb insulators. Cleaned carbs and synced them using a homemade carb sync
tool. (worked great)! then replaced the spark plugs. All this was done after a
thorough cleaning of the motor with all the tupperware removed. ( the PC
actually looks quite badass with all the plastic off). I then replaced the fuel
filter, replaced the petcock with the brass T mod, checked all the hoses and
cleaned and re-oiled the K&N air filter.

springs with progressives, fork seals, dust covers and fork oil (Yuk!) with
Belray fork oil. Checked the front brakes and rotors and they were fine but
decided to change out the brake and clutch lines with stainless steel braided
lines from G&J aircraft as recommended by members of this site.(Recommended
mod). Replaced both brake and clutch fluid (Belray) and took apart the clutch
master cylinder and cleaned it up replacing a torn rubber cup. (the clutch was
sticky but works smooth as silk now).

drive gear oil, also. Then replaced the coolant taking care to remove, then
clean out the reservoir with soap, rocks and a lot of shaking and rinsing! (I
can now see the coolant in the reservoir). Checked all the hoses and they were
fine.

> Next came the Tupperware and windscreen. I spent about 5 hours sanding and
polishing the original windscreen and managed to clean it up enough to make the
23 year old screen look like an 8 year old windscreen. (Not perfect but it will
do) 4 tabs were broken off or missing so I made new ones and fixed another 5 or
6 cracked tabs, mostly on the bottom gray panels. Repaired and painted all gray
panels and they turned out nice! Had to purchase one small pearl white panel as
it was broken in half with one piece missing (the small panel right below the
seat).
>
> Before re-assembling all the Tupperware I decided to paint the bar ends (had
to drill and tap one of the screw holes as the screw broke off when I tried to
remove it) radiator, muffler system, ?and touch up all scratches on the frame.
After assembling all the tupperware back onto the PC, I touched up a few chips
on the pearl white sections then gave it a cut polish and final wax.
>
> The PC runs like a top now and every mod and part replaced was necessary on my
PC... in my opinion. None of it could have been done without first acquiring a
SERVICE MANUAL and from the advice given to my questions on this website. Thanks
to all.
>
> I noticed that the PC still wobbled a bit when riding at freeway speeds but
noticed a thread on tire pressure. I had been running Honda's recommended air
pressure and boosted it to 40 psi front and 42 psi rear. What a difference! The
wobble is now gone! More great advise on this forum! The PC just doesn't handle
like a sportbike but it now handles like I knew it could. I should probably
still crank up the preload on the back shock and change my tires (back one at
least) to improve handling even more.
