23 V4R Loosing Oil…… Some Oil Found in Airbox

Since I own a 23 v4r, and have done a few track days with my third engine, this is my experience. My first engine had a cylinder misfire error within first 150miles of riding and was replaced under warranty.
When my second engine was installed, the airbox was not sealed properly. Airleak testing confirmed this. Due to this, there were dirt going into the airbox which messed up the piston rings. For the third engine, they changed airbox, sealed it and tested it first before installing the third engine, changed the cyclone seperator and pump, and replaced the sprint p08 street filter with BMC. so far completex 3 track days and 1.5k miles on it. Zero issues now.
 
So I’ve just got back from 3 glorious December days at Portimao. The bike was faultless throughout (accept some handling issues that we are ironing out)

Anyhow, got the bike home and in the garage for a strip down, clean and torque check before it heads to MotoRapido in the new year for annual service. Having stripped the fairings, I have found several apparent leaks on the power plant. Both the cylinder head rocker covers are leaking, which is common I hear and no real issue to sort. What’s more concerning is the fact I’ve now located leaks on the inlet side of both cylinders. It seems like the oil is coming out the flanges between the throttle bodies / air box and where it bolts to the inlet side of each cylinder. There are multiple leaks it seems, but it’s hard to see clearly as they are right in the guts of the engine. MR are aware and are going to sort when it’s in for service.

Seems to be from around the same place (rear-left corner area of rear cylinders) that mine went.
On the rear cylinder rocker cover ? Yes, so it seems. Also leaks on the front cylinder bank rocker cover and around the inlet flanges of both banks of cylinders, where the air box bolts to the heads.

And to think that my local dealer couldn’t be bothered to investigate properly, even after I told them its using oil and sent them images showing oil in the air box.

It’s quite bad that they were prepared to let it continue.

I was at the track when mine happened and I sent pictures to my local dealer and the dealer in Germany that I bought the bike from. My local dealer never responded (even though I could see that he had read the message and seen the pictures), whereas the German dealer immediately replied and said do not ride it, get it to them immediately and they will investigate. They told me that they had seen this before and so I guess they pretty much knew what the problem was and what needed to be done as soon as they saw the pictures. I went directly from the track to the dealer and they sorted it within one week under guarantee, which was good considering they had a workshop full of bikes in for service, etc.
 
TBF, I have since approached MotoRapido and they have been great, responded to emails quickly, haven’t tried to fob me off with excuses about ‘this bike should use oil’ and have booked me in at short notice to get it looked at. Hopefully it will get resolved quickly in January and be back to me in time for Jerez in early March.
