In a 2 stroke engine there are no valves and thus no adjusting required.The itself acts as a valve too.
Maybe you will have to rebore the cylinder and fit an oversize piston -kit or if the cylinder is to its tolerance thn fit in new setoof piston rings.

Just did top end on 02 cr80rb. Fired up was running great. Than through the gears started loosing power in lower rpms. Stopped bike and than it wouldn't kick back over. Checked plug for possible foul,...


ouch.. Hey Bagger,, sounds like she seized up... not a good thing...
1. Will it kick over at all??
2. if it kicks over, does it make any grinding or metallic sounds?

What exactly did you do to this bike? IN DETAIL.. why did you rebuild it..what happened that it needed rebuilding?
PLEASE respond on here, in detail,

Thanks..

Dt 230 low on power.bike gets half revs then runs


Hi there, you likely still have the restrictor in the exhaust header. Mine was the same, they are shipped like that as standard. Take the exhaust off the engine and remove the the concentric tube that's in there (you need to cut it out). Instant +100% power, if that is your problem.

Cr 125 02 wont start.makes wooosh/bang noise


you may want to check your card settings and the compression itself as the woosh and the bang noise means that the gas is burning, but not completely combusting.

hope this helps.

93 honda cr 125 r has no power


i bet it is the float needle check to see if it has dropped down to the last notch. i think there are three they regulate the amount of gas that goes to the engine its in the carb and easy to check.just unscrew the top piece and its right there.

Power band


Changing the exhaust pipe (expantion chamber) to a pipe that give more low end toque. Most aftermarket pipes work on the to end of the power range. Or You would need to have the cylinder ported.

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!
