THE black finish on the stock pipes is nothing short of useless. Just one day of winter riding will see the finish simply fall off, particularly around the welds at the end of the can. Thankfully, by the time. you go hunting for a '94 Blade, the chances are the original sitencer willl have been replaced with a tasty aftermarket can. But try and get a stock can thrown in as part of the deal you will need a road-legal one to get the bike through an MoT test. If the bike has a race can it should also have a Dynojet kit fitted to match the carburation to the freer-flowing and louder pipe. There should be little or no lag as the engine picks up from tickover to 2000rpm as you ride it, if it does, the chances are it hasn't been done or it's been set up badly.
