Hi everyone, I'm brand new to riding, and have had my learners and a 2001 CB250 for 3 weeks now. It's a great little bike but has hard a hard life, and I get the impression it's been a long time since it had a really good service. I'm looking to do a lot of this myself, starting with an oil change. I've got the tools and oil etc. I just have a couple of really stupid questions. 1- I was hoping to clean the oil filter/screen out, am I biting off more than I can chew? I have ordered the Haynes manual but it has to come from the states and is about 4 weeks away. If anyone can offer me some advice on how to access the screen I'd appreciate it, as I'd like to get this done asap rather than wait for the manual to arrive... 2- (here's the really stupid question) When checking oil level on the CB250 do you screw the dipstick in or leave it sitting on the thread? A google search throws up both answers... Thanks in advance!
