it's going ok, My mother bought me a new 125 on monday. It's an RG125 1994, by tuesday, it's broken.
so I have to split the engine, new gaskets and seals etc.
I'm going on holiday on the 13th and I'm waiting for my stuff from my man in japan (I wish japan!)
I'll probably start after my two week holdiday in newquay :)

[QUOTE=jcb121;23237]I had to but i didn't in first! there was no power in the bike at all! if anything they were riding it with popped seals.

allways a risk when buying a second hand two stoke... especialy an RG:naughty:
£130!!! times have changed :confused: highly strung two strokes are murder for self distructing in first and second... i managed to melt an RD400 three times in the space of 500 miles(way back in the day when pistons and rings where cheap and power valves hadnt been invented)
if you let the motor reach its rev limit in first and second (ish) because of the low speed ergo low wind resistance and drag, the whole drive train goes slack and im pretty sure any lash in the motor causes enough vibration for the piston skirts start slapping against the liners, a bit chips off the skirt causing an imbalance causing more slapping and it quickly cascades into a disaster
over reving is much less important at 30mph (ish) and above as the wind resistance keeps the drive train nice and taught

i just did a bit of research on the powervalve (i never got my hands dirty on one) if the bike was a bit guttless after 9000rpm (start of the powerband) then the chances are the powervalve wasnt working in the first place... some versions aparently wear out and can drop parts into your cylinder, possibly what happend to yours ?
if you have all the other replacement parts it may well run well enough for your mod 1 without the powervalve running (i think you can assume it wasnt running anyway)
good luck man :sad:
