748 748r Light Refurb, Well, It Started That Way.....

Ref pinpricks - yup, wet down, tack coat, more layers of lacquer, rinse and repeat etc. I have run out of lacquer or would have simply carried on in the bathroom (so to speak) yesterday, laying additional coats that is. Its becoming a bit of an experiment for me. I know the right way, but want to see if a shortcut would work as I simply cannot afford a divorce by spraying indoors again

If you have parts that need a tart up you should give it a go, its good fun if you have the time.

 

Finished buggering about with my experimental fix of the pin pricks in the lacquer and also the curtain runs. No surprise, the best way would be to keep laying lacquer until the holes were filled but, as explained, I simply cannot attempt this at the moment.

The end result is not bad, especially for a fix without lacquer. The curtain run is sorted nicely. Here's what I did.

Before shots:


The curtain run (not so bothered about the pinholes on this surface as will be covered by the nylon chain runner):

I flatted back to show the pin pricks. Applied araldite clear resin to the pinprick areas and left to harden over a couple of days. Carefully flatted back the new resin and also removed the run by wet sanding with 800/1200/2000/2500 grit:






Then out with the cutting compound, polish and finally wax with electric buffer:


Like I said, not concerned about these pinpricks as hidden once fitted, but run removed

:


So, not bad, much better than it was and OK for now. I would say 6 out of 10 and tried some new things along the way.

I will fit to the bike over the next few days and post up a pic of it done. Hope this helps someone.

 

Thank you Andy. I am enjoying your rebuild thread very much by the way.

 

Age and condition of the original carbon fibre resin I think. I’ve think it must have got thin in places and the resin had stopped penetrating the carbon weave. This lets air permeate through and you get a pin prick or fish eye. It can also be caused by not cleaning the grease off a part but that is not the case here, thoroughly prepped and wiped down with acetone prior to first tack coat.
That’s my guess anyway.

 

And after 45 mins in the garage this morning, here is the finished product, showing both the sprocket cover and the swing arm cover. The rest of the carbon was done professionally (won't ever need to pay for this again).

Well pleased.

Just need to source some tasty (gloss black) rearsets per @cookster previous suggestion.

 

They look great, thanks for the pic. Bikes not bad either (but what would I expect from you!).
Checking their website they are good value as you say - £189.95 looks pretty keen. Think I might ask for a set from the Mrs for Christmas.

 

Just a little bit gauche IMHO
