Can anyone who has fitted a new pipe confirm what difference, if any, that a new pipe such as the Leo Vince does to the fluffy low down power of the Tenere? Or is this the character of the XT660 engine and not much can be done about the way the low down power comes in?

Thanks

Simon

I fitted my Leo Vince cans a couple of weeks ago. I was quite surprised how light the standard can was considering how heavy the cans on my XT660X were.

I prefer them with the baffles in. The most noticable thing for me was they seem to have smoothed out the low rev response of the engine so low speed response seems better.

No, I have them fitted, and I have evolved from the pipes, snorkel removal, DNA filter fitted and a kind of Kev mod, the best overall gain comes from the snorkel removal+Kev mod. 2nd is DNA filter and 3rd -and most expensive- is the exhaust.

My advice, don't do it before going the "intake way", there is no gain, not even in weight (just about 1kg).

have fun,

I would recommend you fitted some form of fuelling modification if you are running the LVs. On a dyno run my stoichiometric ratio was a very lean 14:1. Not good.

Did they take into account the clean air system on the bike or disable it for the dyno run as I believe that it can lead to a false CO2 figure making the bike seem to be running leaner than it actually is?

I don't know to be honest Al, the sniffer went down the silencer, they did a few short runs and then did a power run before giving me my print out. I'll have to find out from my dyno knowing mate how much the dynojet dynos are off so I can get a more realistic figure power wise.

Thanks for all the replies.

Has anyone told their insurance company about the Kev mod? And what did they say?

Cheers

just a quote from london biker :

Boosting the stock power from 46bhp up to almost 52bhp, these exhausts also produce an incredible extra 16% torque - which in laymans language means a big hike in the power band from 2600rpm - right up to 7200rpm, the biggest increase being in that much used mid-range 3800-4400 rev band, where the stock power flattens out.

Can anyone confirm if this is the case with the pipes fitted as standard and no other fueling or engine mods.

I suspect its a load of ballony but it would be interesting to know all the same.
