Posting for a little advise really.... I've got a 2008 model 4rt, in June time I had a 280 kit fitted (Athena) heard pretty good things about the make but not so bank breaking as a s3 kit...
whilst running it in after the change the engine was really loud, you could really hear the piston working, I was reassured by a montesa owners this is pretty normal after having the 280 fitted. They were right after couple of weeks it really quietened down but now there is a tapping sound coming from the engine on tick over and the first quarter of the throttle...
I'm keen on the maintenance, I run Castrol engine oil and elf in the gearbox so its not like i'm running crap through it...
can anyone point me in the right direction to solve it!?!?!
cheers.
