if you make it semi auto, can u still use the clutch to engine brake and burnout and all that fun stuff?

[Tadetrain53]

@bandguy360 clutch is still 100% operatable with the recluse pro. you don't really need to drop the clutch with a 450.. just crack it...

[Tadetrain53]

@bandguy360 clutch is still 100% like any other with the recluse pro. you don't really need to drop the clutch to burn out or roost it.. just crack it... you can if you need to rev it out the drop it, yes.

did you need to re-jet and did you just change the silencer or the whole exhaust?

[Tadetrain53]

no I never had to re-jet it seamed to work well and better in various areas of altitudes.

[SlaughterHouse18]

Sounds like u got "off idle bog" my bike does the same thing its annoying

Man that sounds sweet as.just ordered my powercore 4 for my wr 450 cant wait to feel the xtra grunt and get rid of that shitty stock pipe.You would think yamaha would put a decent pipe on stock like the ktm,they come with akro system stock.But hey if its orange its prob a lemon.

Ive been thinking about getting a kx450f and making it street legal. But after looking at some vids it seems its gonna be expensive and a hassle to do the lights and all the stuff. Just better to get a WR450f or maybe a KTM? I will be driving it on the freeway to work and dont want to burn it up all the time. Im assuming change the sprockets? Any advice or suggestions would be great

@raretv7 you are clueless. The bike is in neutral - the clutch is fully engaged. The wheel turns as the revs come up just from the drag of the unengaged gears on the countershaft. Every motorcycle in the world does this.
