What intervals should the top end be checked rd 250 lc 44000 Km aprox 27000 miles runs perfect sounds sweet . Dosent look like any of the head bolts have been touched, main concern is if not checked and then nips up will it cause more damage and cost .
Hi John, You could do a compression test to check the condition of your rings and bores etc. A compression tester doesnt cost too much, plenty online and I saw that Halfords has them too when I was in yesterday. Steven.
