Have You Checked Your Valve Clearance? You May Have A Valve That Is To Tight.

i bought the bike not long ago off the owner of shop, he said he just done the valves and to take it back to him in 3 months for polish the valves again, can valves just change like that after 5 times of going on the bike? (once a week)

Once they start moving, they tend to close up progressively faster each time they are shimmed. If you've dropped more than 3 shim sizes from stock, the valves are in danger of snapping off the heads and need to be replaced ASAP.

Excellent advice. But since you aren't the original owner, you don't know if the shims have already changed 3 sizes..... or 6.... or..... It'd be best to do a complete top end now.

Exactly the problem with buying used bikes, 250f's in particular.

if your valves are out just a little bit, you will actually be able to hear them tick a little bit, otherwise just hold the guy responsible you bought it from, if theres something wrong he can fix it, it sounds like he is a responsible seller if he wants you to bring it back in three months or w/e
