mc21 se 1992 fork lowers.

Fri Apr 29, 2016 7:04 pm » Post: #1 » Download Post

Hi all.
Progress is steady on the rebuild and whilst the stanchions are in for rechroming and some parts are off at powder coated.... I have the honour of refinishing the fork lowers.

Goal is to be ready to ride to donning ton for the nsr day.
2 questions

, 1, from factory did Honda laquer the bottoms as they don't seem to be at present which would help explain their condition!

2: If not lacquered from factory is there a knack to keeping them from corroding again??

Cheers in advance for help

I think when mine were done (by Paul Goat off this forum) he used scotchbrite it get the matt finish back, then re lacquered them.

Yep racer is right, when you use the scotchbrite pads, use wd40 or similar, and rotate them round the leg, not up and down, to get the factory look, then clear lacquer, jobs a good un.

As Tom said I have restored a few pairs of forks, I have them vapour blasted first and then use a scotchbrite flapper wheel.

If you look at a pair of original fork bottoms they have a grained finish although this doesnt run all the way to the brake lugs and other protrusions that are hard to polish, I masked out the appropiate areas and grained the forks with a scotch brite flapper wheel in a drill then laquered the fork leg.

The last pair I had clear powder coated which should be a bit more durable than laquer.

Paul... thanks this exactly what I was looking for!
I thought the polished area had been done after market but looking at yours I now see mine are standard!

I have just gone the first with med scotchbrite and tcut and it worked well.

Hi Paul

Can you advise what you used to strip back the lacquer...I have a feeling that today's PC version of Nitromors won't be man enough...
EDIT: then as I posted the question I read that you had them vapour blasted first, Doh!

Cheers

I wish!!
Sorry for the confusion, I am having a bit of brain fade...that image is a pair of forks Paul G did a few years back.

I am just starting out on my refurb and was tapping him up for idea's but to be honest he has told me how to do it once already, don't know why I didn't remember 1st time round!!
