Bits for a H model

[f17th]

Hiya,

Just hoping you guys can point me in the right direction for some aftermarket parts for my H model bike (H1)

Ive looked around on the ZXR site under the styling section and most bits are for the L model.

I'm looking at giving my bike a bit of an overhaul over the winter.

Respray wheels + Polish the outer rims
Service Calipers and Spray
Possibly paint or polish frame / Swing arm
Cam tensioner

I also need to get a New Chain + Sprockets, What should I go for ?
I have seen a Regina Chain and sprocket set on Ebay for about £80 anyone got this on their bike? if so whats it like.
