engine trouble

[denney_special9]

My bike keeps cutting out badly at full power. i've torn it apart, rejetted, and a number of other things. the only thing i haven't done is put on an after market CDI. Just wanted to get some input on it.

Its a 96-98 RM 125 I think. Had a FMF Pipe w/ a FMF Shorty Silencer. Thats all I know of.

power valve timing ? port work was the engine ok before any top end repairs had an 86 cr that i set power valve timing off. as soon as i hit powerband it would start lugging like a missfire,but consistant.not too sure how suzuki p/valve is assembled
