volcrano Posted June 28, 2011 Report Posted June 28, 2011 Hey guys i need a hand here.when i kick over my motor i can hear this as the piston goes thru its stroke just kicking with it not running.when it is running i dont hear it till it warms a little then it will only sound for a second when i throttle it.if i hold a steady idle or blip it its fine,just giving it a touch and it will make that noise.it sounds like a sea otter to the tee.other description is like there is no lube in the cyl which im 32:1 klotz.could sound like a horn with a sucking sound.its hard to describe like that lol.my gas is like 8 mos. old so im gonna change that tonite as well as all fluids.any ideas?when i stored it last yearin between parts i had the carbs and intakes off and sprayed shit tin of fogging oil in there and taped up with duct tape so i dont see rust being an issue.i also ported reed cages,nothing crazy at all with some tdr reeds.after i put the reeds in i didnt run it for a while tho.i dunno if its reeds making this noise?water pump bearing?it sounds like its in top end somewhere.it has great compression and runs good i just cant stand it.i need to figure it out.btw i took plugs out and sprayed fogging oil in there to for storage so the top end was well lubed.running stock carbs,27.5 pilots,350 mains.this is mu ported 4 mill bike.thanks.u know now im thinking of it,it sounds just like when ur air compressor in ur garage has built its pressure and shuts down,how some have that little squeek/sucking sound as the piston is coming to a stop.thats the best i can describe.help me lol.

Phelps Posted June 28, 2011 Report Posted June 28, 2011 sounds like the reeds vibrating causing a horn (wood tip instrument noise) ussually cause by them not having a good tip seal. Quote
volcrano Posted June 28, 2011 Author Report Posted June 28, 2011 sounds like the reeds vibrating causing a horn (wood tip instrument noise) ussually cause by them not having a good tip seal. It only makes sense.its in the top end,it does it when kicking and when giving a gust of air when hitting the throttle.like i said when rpms are constant or i rev its cool.phelps u got a good set of stock cages for sale?id like to try another set to rule that out.i did change cages and all so tht prob is the case.i had vforce and sold em.if another set of stockers work im gonna have to get a set of chariot cages.ported stockers are better than factory but thet aint to chariot or v3 lol.

Phelps Posted June 28, 2011 Report Posted June 28, 2011 i do believe i have a set of cages laying around. pm me a address and when i get a chance i will send them out. not promising that will fix the issue, but may help since you probably reduced the sealing surface by porting them. my vf3's would do it on slow rollovers, but not while running.
