do high rev cdi kits increase horsepower along with high revs

 

 

theres no ***** power increase, all it does is the the engines rpms go up higher, whitch yes it can help with top or low end speed but can also risk blowing the engine if it is over reved.

 

dont they just raise the rev limit

 

if u raise the rev limit u do increase power technically. horsepower fluctuates throught the rpm band and that is where u get the horsepower curve. if the bike u r working on doesnt reach its peak power before the rpm limit is reached than raising the limit will increase the power u can use. however u have to think how often u will use that. on my 250 the limit is 8750 rpm. i dont ever reach that before i shift and if i ever got it that igh it wouldnt be fore long. u have to ask yourself how often u would use the power. but yes it would give u more power if the curve can reach tat high. and u wouldnt blow the enging as long as u didnt do anything stupid.. hope this helped.

 

I had one on my 400ex and with the pipe and air filter you could tell a huge difference. You could feel the power longer and harder with it on.

 

i have a dump question, but is it ok to hold the trottle wide open on a 4 stroke? I heard that ur not supposed to on a 2 stroke, but not sure on a 4 stroke.

 

with proper jetting it can probably handle it. i wouldn't do it for a couple minutes or anything.

 

is it bad though? i dont wanna try if something will happen

 

it really depends on how the engine is built. you know nascar engines can run wide oped 8000 rpm for 3 hours but thats how they're built. a stock quad especially a honda can probly handle it for 10-15 seconds but then some things may start happening. you may bog it or blow a head gasket or e if u push it hard enough u could damage the piston. just dont do something stupid like full throttle first gear up a hill. if u have a good modded motor with a forged bottom end do what u want. hope this helped.
