And then ask if the EXUP valve makes any difference cos your cables are knackerd and you have just tied it open. Struth. Link to comment Share on other sites More sharing options...

cloudy Posted November 4, 2009 Share Posted November 4, 2009 if youre doing work that serious, and your exup valve isnt working, maybe you'd be just as well getting stainless downpipes. id imagine they'd be the most likely exhaust system to give you a bit more beans in the high revs. personally id stick to the exup valve, bike doesnt run too well in the low revs without it. thats what its for, smooth power delivery.

Moderator Cynic Posted November 4, 2009 Moderator Share Posted November 4, 2009 From what i understand of the 400, its the best of the bunch. The 600 is pretty much a 400 with a big motor in it which is compromised by air filter volume and exhaust routing. A 400 that is designed to work with something like the exup valve is going to ride like a lazy 2 stroke till it comes on cam, probably at something like 9-10 thousand rpm. The bike without the exup and a fubar'd exhaust is going to run rough as old bolts. But the harmonics of the engine with the RPM ceiling of ? 14/15thousand rpm will be all wrong with a 600 pipe. Get the bike running like it is supposed to, with the exhaust patched up and the exup working and with the extra torque that you get the bike may feel a bit quicker but will be a lot better across the box.
