Why pin your pv ?
-
What are the pros and cons I'm really interested in trying the pinned pv you guys say more performance without it pinned but it's more exciting pinned so questions will it harm my servo or any other parts if I pin it and i know it's down to preference but is it better?
-
Well it's more load on the bottom end lol. So wears out components fast if you find you are riding outside the powerband.
Other than that it shouldn't affect anything else.
-
@Calum why do it though does it move the power higher lower I don't understand it?
-
@declan the gases need to escape faster the higher rpm for better power so if it's pinned open the bike is slower at low revs and faster at high revs for example and before anyone says any thing this is an (example) if it's pinned closed ie smaller exhaust port its 0-60 in 4 seconds with max speed of 65 and if it's pinned open 0-60 in 5 seconds max speed of 80

@terry.tz I guess I've gotta try it and see for my self!
-
but if you have a servo then 0-60 in 3.5 seconds and max speed of 80 because the valve opens wider as the engine need to breath more
-
but some people like the feeling of hitting the band i.e the point where the power kicks in which is more violent when its pinned open but harder to ride kind of
-
I think the sound from my vid shows it pretty well.
It just gives the bike a much more motocrossy feel, really impractical for commuting but fun none-the-less.
