9/21/2024 7:23am So I pulled the engine apart and see some wear on the cams and journals. The oiler orifices are all clear. Only thing I can think of is replace oil pump and try that. Seems like it should have lasted more than 30hrs. Anyone have specs on oil pump gear clearances?

9/14/2024 7:06am I cranked it for around 20 seconds still no oil. This bike doesn't have the removable oil jets either so I will probably have to tear it down

9/13/2024 7:35pm What is the best way to clean out the jets? Oil pump gear looks fine.

9/13/2024 5:12pm I tried that and no oil was coming out. Is there anyway to check the oil pressure on these?

9/13/2024 4:15pm Well, drained oil and refilled by the sight glass level. Still smoke out the vent tube. Pulled off the valve cover and noticed the cams are dry and have some wear marks. Has anyone had oiling or oil pump issues with the 23up bikes?

Mine did that when I would put in the recommended 1L of oil. I started dropping down to 900cc of oil and that stopped it and the oil level is in the middle of the site glass. The problem I found out recently is that the manual tells you not to remove the 3rd oil plug that drains an additional 100cc of oil out of the case. So you're overfilled when you put the recommended amount in the case. They corrected this mistake on later copies of the manual. There's another thread on here about it. https://www.vitalmx.com/forums/tech-helprace-shop/23-ktm-350-sxf-oil-ch…

9/3/2024 9:14pm Gotcha. I'll change it and see if it helps. It's just a little hazy. Starts and runs fine

9/3/2024 8:58pm I measure it out. 1100cc. It does cover all of the sight glass I've noticed which is odd to me. My 2020 350 didn't do that

9/3/2024 8:47pm My 23 350sxf has 31hrs on it. I just noticed the other day it smokes some out of the valve cover breather tube. Anyone else had this problem?
