Servicing a CBR125R myself

eidolon · 31 Jan 2010 at 19:25

I'm reasonably handy with spanners so I thought I might as well service the bike myself. It was last done a year ago and even though it's only (apparently) only done 300 miles since then I thought I'd give it a once over just for my own piece of mind.

Oil, air filter, plug etc look easy enough to do but I'm more concerned about the stuff I'm not familiar with yet. I'm new to biking and have only rode the CG125 on my CBT and now my CBR125R so as yet I'm not aware of what a weird noise sounds like or what things are supposed to feel like if that makes any sense. If it was a car and I heard a tappet noise I'd recognise it, or if it was a droning wheel bearing I'd know that but with bikes I don't have a clue so any advice on what to check for would be appreciated.

What else should I be checking to ensure that my wheels don't fall off?

I've found that from having single cylinder bikes they can really do with a valve check every service, mine in the 20K I had it needed adjusting every 2nd service.
chain needs to be checked and lubed. check head stock bearings,and check the brakes for binding ,not really for wear, just as you havent used it in a while it might be sticky.
and tyre pressures although you check those weekly right???

What's involved in the valve check?

Good point about the chain, totallyl forgot about that one.

Wow, that seems like a lot of trouble for a 4 stroke 125 :eek:

. I always thought they were pretty bulletproof. How much did it cost you to have your 125 valves checked and adjusted each time?

In my experience, with a Honda 125 or in fact any Honda I've owned, oil and filter changes, change lubing and tensioning and keeping an eye on brake pads is all you need to do for many miles of trouble free biking!

I understand the feeling of being new to bikes and not knowing how to notice that they are about to fall to bits. Don't worry, it won't!
