Firstly, I know this has probably been done to death before so appologies, I am new to this.
As a newbie I thought it would be interesting to hear what are the favourite mods that have been done by our more wise and distinguished members, mods that have actually been done that is, no fantasy twin turbo all in your head modificatiuons. And, if you've got the time and inclination, a brief description of how you did the mod would be nice.

So far my favourite mods are my NC30 are Halo side lights (White Car Angel Eye Light Headlight LED Halo Ring 100mm off fleebay) and solenoid fuel cut-off linked to my Gp1000t and Intellistart IV alarm.
Peace of mind is a great thing.

For an NC30?
14T front sprocket or 42T rear sprocket.
Rear shock (from an RS250).
BT090's.
Tyga exhaust system.

I stuck some nice stickers to mine and also some shiny valve caps

No description of how you put those valve caps on... tut tut

I haven't done any to mine, like to keep things straight forward.

get my thumbs up

oh and lots of powder coating

HRC stickers gained me 10bhp - Cleaned surface, pealed back and applied, Magic!

My best mod was----------my castrol race suit my bike fucking flies man meeeeeaawwwwwww

Take jeans and t-shirt off struggle to get the waist section of the suit past your arse then get your family to try and stretch the rest of the suit over your shoulders and hey presto one fast as fook bike cha ching...

Seriously though you have already found the best mod and it's this site.

Come to think of it, an NC35 shock linkage and knuckle to raise the rear.
