dt 125 not startin on kick

iv got a 05 dt 125re,this model dosnt hav a kick start jus a big plastic bung wer it should be.. the bike rarely started on de electric start and now ders not a kick out of it.. dnt mind de electric start, i converted it to a kick start the other day and it still dosnt start. wen i kick it it sorta feels like thers no compression, yet wen i start the bike on the run by poppin de clutch it goes like a rocket no shortage of power.. aswell the kick seems to hav a reali short stroke.. reali tho it seems like theres fuk all compression, but there obviously is if its runnin so well.. so anyone hav any ideas or suggestions? also i read on some other post dat someone else had similar trouble but wen he tilted the bike to the right it had more compression wen kicking? i kno dat seams like bollox but tot it mi be worth mentionin... cheers for readin
