Suzuki 2-Strokes: several gt250 ramairs
i've seen the great result of allan's gauge resto's, but those inner white casings look like new. are they new or is there some was of getting the orange discolouration off them? i've tried alsorts, but nothing seems to work. photo below of some i did years ago and the orange is plain to see. spoils it somewhat :( some are worse than others, but nearly all my spare inner casing have this orange colour on them and i'm blowed if i can get it off. any ideas? secrets?
cheers, dd.

Hi,
I think that the orange discolouration is actually the old glue that holds the lens in place, well at least it was on my 380 clocks. I found the only way to get rid of it was to remove the old lenses and scrape out the old glue, then I replaced with new lenses bought off e-bay. Only time will tell if the glue I used will react the same way.

ee, another derbyshire lad :D tbh, i don't think it's glue, as i always clean them thoroughly. it's just nasty discolouration that refuses to be moved. the only thing i haven't tried is polishing it out with different grades of compound, like on milky headlamp/taillamp lenses. the glue i use for sticking acrylic lenses [and plastic sidepanels] is technicoll polychloride for hard plastics. takes a long while to go off, but when it does, it's STUCK. that's it near the bottom of my photo.
cheers, dd.

Hi dollydog,
Are you saying you clean the outside of the lens ? I was talking about the underside of the lens where it sits in the recess of the outer casing and where the glue is applied.
Yup another Derbyshire lad in New Mills.

I removed the workings then, used a fresh Stanley knife blade to scrape it off on mine. Painstaking work, took me ages.

The problem is people take out the lenses, once you do that its near impossible to make them look correct again. https://www.facebook.com/photo.php?fbid ... ater&ifg=1

Yes but the lenses are the problem. They are plastic and deteriorate with age. After 40-odd years you have no choice but to take out the lenses, if you want to still read your clocks. The best option would be to get all new clocks, but they aren't available. So reusing old yellowed casings and fitting new lenses is the only option possible for most folk.
