DIY GoKart motor noise repair

Hi has any one with out of warranty GoKart trolley ever tried to open up motor casing to try and stop irritating whirring noise?

I have the same noise, out of warranty too, and the same thought about cracking it open too ... after looking at the case and screws I've come to the conclusion that stumping up for the service will give a better chance of success.

it's £100 all in for service, the machine will be cleaned, serviced and returned within a week and come with a 2 year warranty, works out at less than £1 per week

Send it to Go-Kart, no brainer! They are such a superb company and whatever they do for you, it will be perfect!
