Help needed please!
Recently I wanted to get into tinkering with motorbikes (I have little experience but everyone has to start somewhere I guess🤷♂️🫣). I wanted to upgrade from a 50 so I put a Motoforce cast iron 70cc kit on my Derbi Senda xtreme sm 2014 all gaskets on done everything up everything seemed to be in check.. then as I started the bike it had coolant leaking from the exhaust manifold and also coming out from the bottom of the head where the base gasket is.
It seemed to be built up in the little port too(image attached) I’ve drained it all out and changed the oil also as it was contaminated with coolant it seemed but flushed that through. It could possibly also leaked into the crank case?
My question is what happened to be causing the issue and how can I avoid it happening in future?
Any help / advice would be greatly appreciated guys, like I said I’m not very mechanically minded so I’m learning as I go along..
thank you!
