As the points regarding suspension are well made.

I was kinda looking for an approx list of parts / price to see what effectively could be achieved on a particular buget.

ie
PC111 - £300
Dyno time - £40/hour
Custom exhaust - £500
Blueprinting - £400
Lightened flywheel - £80
etc, etc


Tim

By my interpretation of the rules a lightened flywheel is illegal - what does everyone else think? It's not specifically mentioned as an item you're allowed to change and the catch all statement about mods not specifically mentioned are not allowed seems to cover it?

I could be wrong ...

"Lightened flywheel - £80"-you'll not be doing that of course young Tim since it's outside the rules..............??

Surely 'blueprinting' is outside the rules too?

IN FACT - There is no reason to have an engine taken apart/re-built by anyone as you can't do anything to them according to the rules.

So it kind of begs the question, what are these tuners doing?

The rules allow you to fit an exhaust, air filter, PC3 or Dynojet kit and set the cam timing... nothing else.

How engines range from 58-68 is a bit confusing considering the lack of mods allowed.

Must be some good engines and some not so good engines I suppose.

[domski]

Not all dynos are equal. Not all are calibrated. Not all are calibrated or maintained to the same std and some tuners add "the bling factor" to the readings to gain business. I have personal experience of this myself.

As 600 Pantah racing engines in the early 80's were delivering 80+bhp then I suppose it's not beyond the means of some to attain more than 70 now...whether those means are legal or not is open to question.
If people are getting 65-68 now then they are in minitwin territory (most sv's are in the 65-69bhp bracket) which, for an old air-cooled 2 valve motor is pretty good going!

Looks to me that its time to strip some engines at cadwell.How much does a protest cost ? X 20 = ?

[domski]

Who's gunna check them and know what they're looking at?

Could be the most fun all year

My 620 sport makes 60.2 bhp at the rear wheel, please let me know where i can find 10 bhp more . I think that the over all set up of the bike is more important than bhp. But i may be wrong ?

quote of the year imho.
