Clutch problem? Honda XR 125

[binfieldx]

I was riding to work going around 50-55MPH then suddenly something clicked and the bike came down to 40mph almost instantly and wouldn't go above that. it's also making a horrible loud sound like metal vibrating when you rev the accelerator. It sounded like the brake disc had come off the front or something! I think maybe the clutch has gone on it? I can ride it but it doesnt rev high at all and sounds like it will stall on higher gears. I can go max maybe about 30mph on it?

:D oh dear..........see cmsnl for whats involved with the clutch, is it nutted on or circliped on etc.........

does the clutch behave normally?? or is it being difficult to get in gear or out of gear, and does it seem to slip??

any noises coming from the clucth side of the engine and does the engine rev freely when its out of gear? does the engine start normally and does the exhaust glow red hot?

drop the oil and see what metal bits come out, a pic would be good.

i wonder if its broken a cam gear? this engine is cg based???

depends whats wrong.........see cmsnl for the exploded views so you know whats involved, if the clutch is circliped on , may be that has come off????????

where is the oil filler/dip stcik?? and what can you see when its out?? can you see the clutch "gear" and/or crank "gear"......is there a tooth missing or damaged??

see cmsnl..................drain the oil and examine, and take it from there............if considering a garage, remove4 the clutch cover and have a look.

its best not to ride/run this engine till its fixed.

if you can post the relevant cmsnl view ( of clutch, how its held on, how its driven and weather there is a centrifugal oil filter fitted to this engine ) on here, do so........it can only help. :karma:

Most XL125 engines are more like the CBR an overhead cam unit
I had the version for a time nice until I lunched the gearbox in an off road spill and the bits did the cam chain and valves

Check the oil level if OK drain and look for broken bits and thin filthy oil
The check valve clearances

These engines don't do well with dirty / old oil

The 2003 onwards XR's use the CG based engine!
The earlier XL's use engines based on the 1970's CB100 engine!

so metally noise comes from the gear pedal/flywheel side mainly........have a look iunder the flywheel cover for anything floating around under the flywheel..........what did draining the oil reveal?? metallic bits in the oil??
