But he also already said in his first post, that he didnt want to spend huge sums on money on it.

Look at the post from Sarah further dowm, talking about £2800 to £3000 that is in my book alot of money.


At the end of the day its not my bike. I was merely albeit poorly trying to point out that I thought he had underestimated just how much cash this was going to cost...

Anyway I'll shut up now.

I am genuinly interested and not be sacastic!

Hey thats fine, I know your not

Top speed, hard to be accurate as only ran that on racebikes which dont have a working speedo. The only data i have is from Steve's bike but that was a full blown 700cc motor with Nova gearbox. He slipstreamed Phil Read Jnrs bike at Thruxton and that bike had GPS measurement of 161mph, Steve snook past him!. Gearbox ratios played the major part though as the stock SV box is restrictive for top speed. Steve was running I think from memory gearing of 18/39!!..it pulled off the line though like a wet trump

BHP wise the 650cc spec tune ive mentioned with a Leo Vince pipe made 82bhp. The bike was built from a stock road bike which measured 68.7bhp when it came in. We were using an Interceptor fueling controller which gives a little more scope to tune the AFR better than direct mapping but that just built a better curve rather than overall BHP figure.

Its not just overall full throttle BHP that gets a bike going quick. Ok it looks good down the pub and as a comparison but the way the bike makes the power is just as important.

Well as a comparison the original owner of the 700cc engine I have spent £1800[1] with jhsracing some years ago to get it bored out and it currently gives ~79BHP@rw. That gets me easily hitting the limiter at about 126mph in top down park (as that's what its geared for), it actually could now do with gearing up slightly as it was geared as a 650.

[1] I bought the engine s/h of a mini-twin racer who was swapping it for a 650 engine and it came complete with the receipt for the work. I paid rather a lot less than £1800

You can get most of the gains yourself with info that's on the net, or save a lot of money by doing the donkey work, like pulling the motor out and bolting throttles and exhausts on yourself.

And even when well set up it will still be a ****sight heavier.

Though to give the TL motor it's due, they can be tuned up to a mental amount of horsepower. But if you were going to do that, why didn't you buy a GSXR1000? You can tune those to a mental degree too, but why didn't you just buy a 'busa?

Exhaust systems are the way to go. I agree with the lads above, I had a Leo and could tell a difference...
