ok so my boy busted hi *** on my bike and now if i put my hand over the exaust it cuts off any one know what the hell is going on???

 

... that is normal... you put you hand ove any exhaust it will kill the engine

 

it never did that before and i tried it on my buddies gsxr and it kept puffing

 

Why the hell ya putting your hand over your exhaust? LOL sup is right. Left my plug in a few times and it won't start with it in.

 

What rpm's is the bike idling at when you do that? Is it the same as the other bikes you try it on?

There should be enough engine compression so that it does not stall out, maybe a compression test is in need...

 

i dont know why i did it that time i guess i was just giving it the once over after my homie busted his *** the retard dumped it in the grass cuase he got scared

 

1350 idle and i say your right so where do i start and how do i do it is it easy or does it suck enough to pay some mechanic

 

if you block the exhaust the engine will stop. it isnt some bikes it is a matter of mechanical engineering. an engine absolutly needs 4 things. GAS, AIR, EXHAUST, SPARK. without any of those it will not run.

if your buddies gixxer is still running when you cover the exhaust then there is a leak in the exhaust somewhere that it is comming out. (tell him to buy a kawi)

im not meaning to sound like a dick about this, just trying to let oyu know

 

I agree that if you shove something in the exhaust that seals good enough to not allow any exhaust out, it will stall eventually but you should not be able to just hold your hand over the exhaust and make it stall.

A compression test is easy, you need to get to the spark plugs which means removing the gas tank. There is a tool that screws into the spark plug hole and has a gauge on the end of it. With all the plugs removed and the fuse to your fuel pump removed, you screw it into one hole at a time and crank for 5-10 revolutions until you get a good reading. Also have your battery on a tender or charger because you want a fully charged battery or the readings will be low due to the engine cranking too slowly.

 

Mabye he fixed an exhaust leak for you.[sm=smiley2.gif]
