engine over revs in idle and trans oil pouring out of overflow

[chr10jlr21]

I installed a new cyclinder base gasket and started my bike. I cleaned the k&n filter, it was still a little wet but I installed it anyway. I took off and the bike was sluggish. I took the filter off and the bike ran great for a few minutes, thats when it started to over rev really high and I noticed transmission or crankcase oil pouring out of the overflow tube.

I filled the crankcase with a little too much oil but I could see what looked like air pockets in the oil tube as it was going into the carburator. Also, the bike was awfully hot with all of this going on... I did have the bike up in the air on its back wheels while I was changing the gasket. Do I have air in the lines? Do I need to bleed anything?

Is the filter being off causing the high rev and what is pushing the oil out of the overflow? Is the bike sucking in too much air without the filter on and pushing it out the transmission and into the overflow?

put 750 ml of oil in your crank case and put your filter back on after its dry.. then see how it acts

Should I stay away from the 5w30 I put in it and go with a different oil?

buy yamalube or bel ray or something dont use regular oil

 

[Stryder917]

use bel ray 80w motorcycle trans. oil, that's what i use, it is great.. either use that or yamalube 4... normal motor oil has additives that increase friction... which sucks .... so yah.. dont use just normal oil..

about the revving... go check your reeds for a cracked or damaged reed valve...

if that doesnt work make sure you clean your carb really well to make sure the slide for the throttle isn't sticking when you use it...

OR it might also be excess fuel in the cyl. and could be trying to burn it off and keeping it running even after there's no gas being put into the cyl..

It takes 650ml of oil, says it right on the cover. The reving was caused by leaning out the motor from no air filter and the heat.

Im headed to my son's house to work on his bike today. I will leave an update this afternoon or evening as to the results. Thanks everyone for your help...

Hey anyone know exactly where the fuel/air mixture screw should be set? My son had it all the way to the right...

start turning it out a 1/4 of a turn at a time till it idle's where you want it to..

 

[blasterman87]

it should be between 1 1/2 and 2 1/2 out. turn it out untill the idle stops getting higher, if you have to go more than 2 1/2 out then your pilot jet is to small

More than 2 1/2 out and the pilot is to big.

 

[mr_3_0_5]

dont mean to thread jack but if mine is only 3/4 of the way out am i running to big of a jet??

 

[blasterman87]

yeah sorry i had it backwards for a second lol newnicks rite over 2 1/2 is to big of a jet and m_305 id put a size bigger pilot jet in there and see if it improves it any

 

[hickskateboarder]

do not use the air mixture screw to adjust your idle.....

 

[blasterman87]

yes hicks right on there, but you do use the idle to see if you have the right jet size
