That might work if the mufflers were the only silencing part, but that huge tray underneath is part of the silencing. Also, the note of the exhaust is derived from the shape ( and thickness of steel)

The bike runs very lean as standard at around 3000rpm. Good acceleration from these revs depends on twisting the throttle a bit because there is an accelerator pump which adds the correct amount of

An old Triumph expert suggested that I should just sharpen a piece of narrow rebar, and hammer it through the stock exhaust/baffles bit by bit until the sound deepened. Anyone tried this? My Canadian

What revs?

Hm....All Yamaha trail bikes are called XT's. The slightly more hard-core versions of their trail bikes are called TT's, but we rarely saw them.. The Serow is an XT and is a lowish 'old school'...i.e.

Seems to be under gentle acceleration. Does not happen often, it's abit like the engine 'snatching' slightly. wrote: ride.> >

Yes, but there aren't many companies making repro systems for the classic bike market...Think about it.

He he...been there. There is a trick you can use though. If the bike is pointing uphill...and they usually are when they sop...turn it around, point it downhill, pull in the decompresser lever, stick

Mmm, sounds like a lot of work, I take it you have looked at the W650.de shop? http://www.w650shop.de/Tuning/tuning.html Mark,

HAze Not sure you would know but how easy is it to register an old BSA trial bike, that up to now as been used only off-road?

I have fancied going greenlaning for ages. I even got as far as talking to the TRF at the BMF this year, but that is as far as it has got. However the two piece of advice that they gave that stuck in

I've just sent you a very short video clip in AVI which has been trimmed in Windows Movie Maker. I'll send another short clip direct from the camera. They are both well over 2 mgb or I would have sent

I looked at one or two others and at that time, Armours were unique in that their stuff was designed for use rather than show....Thicker metal, stronger internals..etc etc Jon

Don't worry Laura. , Daniel's confusion may arise from the fact that very few proper competition bikes can be used on the road In the States. Most trail type bikes over there are very road oriented.
