Scoot pulls really well with the Taffy on but I'm thinking about a BGM clubby if it allows me to rev on a bit more..

Ta.


Spoke to Ian Frankland about this at Cadwell last year. He said that Taffys used to sell shortened manifolds to help the pipes Rev on a little more. He said that 10 mm shorter allowed the pipe to rev on a further 4-500 rpm, obviously pushing the useable power that bit further up as well. Note, he did say it was a balance and that drastically shortening the overall
Length of the exhaust will initially make it a screamer then too far and it will kill most of the performance.
Might be cheaper to try and get hold of him and see if he's remade the shorter versions or get one modified? If you want the running boards back on and a standard looking pipe set up then the Bgm Clubman is a great choice. I fitted one to a mates IMola ( although somewhat altered) I'm really impressed, great all round pipe.

hi soullad you say you fitted bgm clubby to your mates imola, just fitted one to mine,what did you have to alter ? cheers tony

Sorry for any confusion Tony, it was the top end that was altered not the exhaust, that fitted fine.
Revved past 8000 on the dyno, made around 19 HP and 15 ftlbs if memory serves me well, not bad for a small block Clubby set up.

I have bought some more bolts for the cowl and tightened everything properly. A friend at work is going to weld the tail pipe bracket so that should be good to go. The Real pain is that when I took it to bits and rebuilt it tonight the exhaust bracket stud I thought I had lost has in fact snapped. I guess I will have to drill and re-tap it to m7. It will have to wait until I get back to Rutland at the weekend when I have more than an on the road tool kit.

Every journey is an adventure.


Use a Wurth Timesert if you can mate, ask a friendly mechanic for a single M6 one :D

Rode back up from Portsmouth today in day light and scooter sat comfortably at 50/55 until going up hill. For one ar*e clenching moment it touched 60 on the M25. Not bad on a Friday afternoon. Now I just need to sort the snapped crank case stud and find out why the kick start mechanism has just started 'chattering' on first gear and it will be ready for something else to go wrong.

Thanks for the help and advice
