If the carbs are CV carbs, pull the tops off and check for rips in the rubber boots

Welcome

Giday and welcome to the CBRF

Have you checked all the basics yet?
Charge from the alternator , battery , plugs , fuel filter (if she has one fitted)?
Again, this type of issue could be caused by quite a few different things..

When she revs out over 5000 , does she make any weird engine noises ? popping or gurgling ? or is it just normal , but slow to build?
