So i planned on a ride this weekend and decided to do a leak test..I'm losing about 3lbs in five minutes.the leak is so small i can't seem to find it any where..maybe crank seal? It's such a small leak..so question is should i be ok for a ride.i will only be riding for no more than two hours.. thanx in advance..then I'll come back and try to find it again..
 
I went to 12 psi, it drops to 9 than barely moved at all after that.. i thought it might have been my tester but i checked all the fittings and they were good
 
you should never ever go over 10psi. or risk blowing your crank seals out
7psi is recommended and suffecient !
 
your prob ok. but test it again pump the motor to 7 psi an spray everything down with soapy water, if you have any leak even a very small one you WILL find it with soapy water.

as long as it isnt crank seals or case halfs leaking
 
Great vid AWK.. Thanks,,, i seem to be ok than. Although I doubled my pressure from what video stated, maybe i shouldn't do 12 psi????!!!! What does every one else do?? Is 12psi to much? I've been doing 12psi for a long time now.

7psi or risk kissing them crank seals adios
 
Yeah i did soapy water test sprayed everything. I was all up in that motor, my neighbor must have thought i was a weirdo . All seemed ok.. pumped it up had a beer checked it and only drops a tiny bit.. I was just concerned because last time i did 12 psi and it didn't drop at all.. that was last year though.. Thanks guys.. I should be good to go..
 
Dam.. 7 psi it is.. where ever did i get 12 psi.. ???? I'm calling my self lucky i guess.
 
i had an issue dropping psi slow, turned out it was the bicycle pump, i left it connected after pumping up, once i took it off after pumping, the psi stayed solid for a long time
