Latest ADS5 Vs Taffy on TS1 225......
Another question is what was the standard ts1 designed for? 8000 to 8500 I would guess...?

Everything you say is correct Tony , we all know that 2 strokes work best at high rpms that's the nature of the harmonics but in the real world away from the race track the secret to a good road bike is torque where it matters and that means torque at engine speeds that correspond to the road speeds that the bike spends most of its time. What is the point in having a Lambretta that can't pull forth gear unless it's travelling at 70 mph and when it reaches that speed it can't keep it up for more than a relatively short time . lowering the gearing doesn't work as you would end up with a bike that can accelerate ok in town but as soon as you reach an open road it is screaming it's nuts off trying to keep up with normal day to day traffic If that power curve related to a modern water cooled 4 stroke motor bike then it would be a different story but it doesn't it relates to an old poorly cooled 60 year old design 2 stroke that can't sustain 7-10,000 rpm any more than the average family hatchback can. A Lambretta exhaust that makes so little torque & power below 6,ooo rpm but then comes into it's own once it hits 7,000rpm is a race pipe and when put into that category then that's a different ball game.

Thanks for your input Gadgetman don't need to put you on the waiting list anytime soon then? 
Don't think we need to get too wrapped up in the actual figures of the graph as Tony says the results are different to the level of tune of the motor. As I said in the initial post the two pipes shown are different one renowned for its torque and the other a fast road pipe, my intention was to show the graph volume and output really as you can't really say it does x hp at x rpm as they're all going to be different. Putting the ADS5 on my Tour tune TS will bring it down the range.
As I've posted before this is the same pipe on a JB240 against probably the biggest selling expansion chamber on the market.......another happy customer.
The ADS5 is lower down the rev range than the ADS1 'Race' and theres plenty of them buzzing round here I can tell you.......Infact another order has just been taken from SCK Germany for the ADS1's so having power up the rev range can't be all bad.
I suppose theres a pipe for all taste and all seasons. What do you ride?? And were do you like to sit when your out and about eg rpm/mph??
This pipe has inspired me to build another scooter for blattin about and I can't wait!!

Surely there's loads of lambrettas that can sit all day at 80gadgetman wrote:Everything you say is correct Tony , we all know that 2 strokes work best at high rpms that's the nature of the harmonics but in the real world away from the race track the secret to a good road bike is torque where it matters and that means torque at engine speeds that correspond to the road speeds that the bike spends most of its time.

thats what I read on most scooter forums? Still a wider powerband on ads pipe in that graph tho gadgetman.. but as you say... horses for courses and I'll shut up now
