Lacking bottom end go

[FAT50s]

Hey i have tried too find a answerto this everywere but i have a 09crf50 fewbasic mods
I recently added sik 50s heavy duty clutch springs and now it seems to have no balls down low till i get the revs up abit ,
Could this be because clutch is sticking on untill revs build up or another problem
Any help would be much appreciated.

Also what size intake manifold is a crf70 got

Cheers

you might need to adjust your clutch, it might be just slipping as it hasnt been set once you opened it up

Id just tighten the nur on side of the engine ?
