Thankyou soo much for the help and advice everyone!
"also, the factory pro ignition advance and velocity stacks give you a little bump... and having a 49 stater is preferred to having a CA model"
Can I please ask what this means? I am still learning the lingo.
I guess I'll be getting the 01-02 undertail pretty sharpish then!
I need a new air filter, can I confirm which is better as there are mixed views here!
I was told by the guy at factory pro that this bike is better off with the stock air filter. Maybe that's just with his jet kit. There are several people who run aftermarket air filters and say it runs good. I was to understand that it creates a lot of turbulence, etc.. It can also make it harder to tune the carbs accurately. If I had all the time in the world I'd get one and work on my jetting and see what I could do. Maybe I will try it and settle this debate myself.
And the ignition advance module can't really be found anymore, but what it does is advance the ignition spark timing. This makes the spark plug spark sooner in the stroke which slams it down harder and makes more power. It also will require premium fuel after that mod. The velocity stacks are badass looking little megaphones that go on the carbs in place of the stock ones. They have better length and much better flow, and make the air and fuel rush into the carb with more velocity, which results in more horsepower.
Also how difficult is it to Re-Jet the Carbs? Can I do it at home or shall I take it somewhere?
It's not very hard to do. There's no special skills required or anything. But it is a pain in the ass. The allen head screws on the intake boots are very difficult to get to. The link in my sig has some pics of the screw locations, etc.. If you are decent mechanically, you can do it. You just have to take your time, keep your cool, and need to have common sense. You need to disconnect the throttle cables and re-adjust them, etc.. The tank and airbox have to come off, the carbs have lots of hosees to reconnect. It's easy but very in depth.
