get a heat gun on the plastics where they have faded, works very well on car plastics too,
obviously dont go in full heat and stay on one spot, work around a small ish area with gentle heat, you will see the colour return.

The side panels looked good enough for me to put on the rest of the kit which I think looks good.
I had fitted an after-market front mudguard so the Enjoy Mfg decal wouldn't fit. Also, the headlight decal is for the white or US style headlight surround so that one also got put back with the spares.
I needed a headlight decal for the TTR I rebuilt with my brother-in-law. The bike is for him as he wants to try his hand at trail riding
I had a couple of Enjoy Mfg decals spare that are designed to fit the OE shape headlight and, as I had nothing to lose, I had a go at trimming it to fit the UK headlight surround. I think the result is quite good.
