Quadzilla Buzz 50

Maddox's first time on his quad. 3 years old. Exhaust and carb restictor still in and throttle screw about 1/3rd out.
I had the tyres inflated too much so it was a bumpy ride and after 30 minnutes his thumb started to hurt from the stiff throttle but I'm sure it will free up with some use.
I initially looked into the suzuki lt50's and yamaha yzf50 and finally decided on the buzz 50. Can't fault it so far.
I did some testing with the remote cut out as I couldn't find any info on the rage it would work. It safely cut out the engine 60meters away....May go more but that the furthest he was from me.
leave any questions in the comments and I'll try reply.
