I just installed the OKO 21mm carb. The engine was running good before, but had a hard time idling. I put a 34 & didn't have any other choices on the main jet, so I left the 105 in for now. After the carb install, idle got way better. It felt like a completely different moped with more power.
I took it out for a test drive. I felt great til i got to the upper speeds. I could feel it bogging. then like a burst of power slowly being unleash. After the ride, I noticed oil spattered everywhere. I'm pretty sure it's coming from the valve cover breather tube.
Is it normal to start having oil come out of there after putting in the Carb?
I could easily make and oil catch can for it, but I just want to make sure it's not going to be any other issue coming up.
Thank you guys,

That should hook up to your air box.

I get that if I over fill the oil slightly but u can not cap that it's either got to be open or hooked to air box. I run a oko 21mm to idk where u located but I got a 50mm kit ,stroker crank,bvh,and tons other upgrades and it took me a long time to figure out the jets bc I was thinking it should need around 100 to 110 but man with the 50mm kit and bvh before the stroker crank I was at a 88 main and 37 idle and now with the airsal 50mm kit and stroker I'm setting in at a 94 main and 39 idle. One thing I'll tell u don't buy jets from Amazon/ebay from china they don't work well I had a 37 hoca idle and a 40 hoca. The 37 was slightly lean and the 40 was slightly rich so I had a cheap jet in a 39 put it in and it was leaner than the 37 hoca het. I ordered a 39 hoca and it was perfect. So if u don't have get a crank case breather it is good to have and let's the motor breath

Also idk what ur set up is but if u have a stock cylinder that 105 is way rich u could be getting fuel past the rings raising the level and thinning the oil out. If I run mine with the stroker and 50mm kit ,bvh ,cam , open exhaust and put the 105 it loads up with fuel so at least take a look and smell if ur oil be sure it's not getting fuel past rings mine won't run past 3/4 throttle with the 105 in fuel starts flooding carb and in oil |
