That XTZX660 lump.

Apparently I have one of these lumps in my 06 Aprilia Trail and it’s a bit short of horses by my reckoning.

I’ve got the Arrow cans and the K&N filter all raedy to go but I don’t think they will give me the extra 5 (or more) ponies that the beast needs.

Anybody got the (cheapish) secret of finding where they hid the power this thing should have or got suggestions of how to find some extra without negating the warranty?

Have a chat with TTS mate.

You can do all sorts with these lumps, very popular with mono racing:)

Thanks ChunkyMonkey.

Looks interesting but needs a phone call.That’ll be on the fiirms time then.

Got one of those from an old friend by chance just after I posted. He tells me that a reliable 80 bhp, min., is what the mono guys are looking for.

So where did Aprilia manage to hide 30? Can’t be that easy being sloppy. Took the British bike industry year of development and crap management to get that bad.

Other suggestions still welcome.
