If it happens does the bypass systen fit my bike?

I've had blowby on my RK but it seemed to be more prevalent when lugging up grades.
At least for me, grabbing a lower gear seemed to help reduce the amount of blowby.
Can't say why but since&nbsp\\;I put on the Mik42, haven't had a bit of trouble

Nice set up for a sporster. For Lee123 if you haven't had your cam chain tension shoes changed yet I would have the shop check the umbrella valves and the oil separator/filter in the rocker covers. this could have something to do with it. Some one mentioned watch your oil level, the softail engines(B motors)&nbsp\\;are more prevalent to this. I have 31k miles on my 02 dyna and haven't experienced this, yet. Yes it's wound up every now and then with two up. Good luck.

 

First try not filling the oil past half way between the lines measured hot.

 

my scooter does it sometimes, most often after an oil change
