Having just had my bike serviced we used fully synthetic oil, but have been reading through some stuff and have found many readings saying that semi synthetic should be used.

Will i be damaging my bike's engine using fully synthetic oil.

Im not sure about this but I think fully synthetic shouldnt damage the engine but it might make your clutch slip..

Again im not 100% on this..

No it wont damage your engine at all, but you will benefit to change back to semi syn..

I use fully syn in my 600rr but its the rock oil XRP which is designed just for high performance race bikes,
in my NC30 race bike i use rock oil semi synthetic which is a quality oil designed for motorcycles, and its not too expensive at £19.00 for 4L..

I put in halfords fully synthetic on the last oil change. And its working really well on the track bike which gets trashed. Gear changes used to be sticky when it was warming up but now silcky smooth. You get it in 5L which is two oil/fiter changes for next to nothing. Anyone else using it? So far its been good for me anyway.

Now that's a interesting point about the clutch slipping because when i bought the bike when you found first gear and tried to take off the bike just stalled and it took a wee while to get it to go but i think the clutch got adjusted and the answer i got for the problem was it was the wrong oil that was causing this and when the oil was changed it was fully synthetic, but it is now happening again but not so bad and was just wondering if it was the oil

But maybe with me being inexperienced i'm just being paranoid.
