I used to have something similar when I had my probe, I bought set after set of metallic red valve caps, until I gave up in the end................I think just about every kid in my area was riding around with metallic red valve caps on their bikes.......little sods lol!:sosp:
THe chavs in my local area are the same, however leave a tray with a pack of Green Rizzla and a packet of 20p space raider crisps, and copy of 'UK NOVA' next to anything valuable and they will instinctively go for the tray instead of your precious [insert item of value in here].
I must be very lucky - I have chromed valve covers and caps and never had any problems with any of the theiving little gits, so I'm pleased to say mine are still on the car a year after I put them on.....just keep my fingers crossed they stay that way.
Glue'em on mate!.....Hmmmmm...on second thoughts...maybe that's a bad idea....I know :idea: ...wire them up to the battery so when the little f*****s try and knick them they get a little more than they had bargained for (although this maybe against the law??? lol)
