Broken ring on suzuki rm 125

I had a prior problem with ring breaking, causing bore damage. I had the bore re coated by Nickosel, engine rebuilt with genuine parts and put back to original specs, after 5 hours the ring has snaped on the exhuast port side. Any suggestions would be very much appreciated as we are at a lost at what to do next, bike is running slightly rich and running on a 30 to 1 fuel mix

Kinda sounds like your cylinder as lost its shape. as pist goes by exhaust port it lets the ring open up and the lip of your ring catches edge of your port window

No compression on my rm80


How are you testing for compression? This should be a 2 cycle 1 cylinder engine. Very simple. No valves.No compression is a mechanical problem and on this engine it could be a blown or missing head gasket or damaged piston and/or rings. Lack of maintenance on the air cleaner, no air cleaner, improper oil in injection system/ mix, no oil in former can all cause damage. More info needed.

Suzuki RM 125 water is mixing with the gearbox oil how do I fix it, or what is the cause. The water is leaking from the cooling system and turning the oil milky. I have just changed the oil and filled up...


Did you do the reassembly yourself? If not, take it back to whoever did because the reassembly was done incorrectly. Oil and water mixing can only happen at the top or bottom ends of the barrel. Either the head gasket is not seated properly or the barrel to casing seals are not properly installed

I have engine coolent leaking into my clutch oil on my 1992 suzuki rm80 "its not a 03 rm 125"


Have you recently had the engine case apart? [even if not], ..check your rubber O-rings [seals]. These o-rings, located inbetween the clutch case cover and the motor itself,...if damaged, allow coolant to seep into the oil.

2003 Suzuki RM 125 with no power band.


Scatter gun approach > thoughts to check out > > >
Clean and dry the air filter? Go back to a stock main jet, at least to check things out? Are "O" ring seals on the main jet going bad?Partial internal collapse in exhaust (remove exhaust pipe & do a quick run down the alley), Install a new stock NGK spark plug, Be sure battery connections are clean and tight, Be sure intake manifold and carb are good and tight.

Hope this helps!
