hi
theres nothin decent on tv tonight so i can try and answer your query
from the direct problems i have encountered.
im just installing a new 71cc engine in a spare bushpig i bought a few
years ago
and im doing a couple of things to structually improve it so i dont
run into the same issues with my other.
some things to look out for are
1. the original rollers on the bushpig are crap they wear and dint
very quickly and arent a smooth ride.
ive just replaced mine.
2.the chain stretches and the bushpigs never came with a tentioner but
you can loosen off the drive cage bearing mounts and pull the drive
cage back to retention chain.
3. i wrapped a bit of pvc tape around the ends of the roller axels
where they inserted into the plastic shell
to reduced impact and wear on the shell itself.
4.ive just strenghten the underside of the steel footplates on my
bushpig so it can withstand impacts from jumps
and i also sandwiched a thin piece of rubber between the shell and the
plate for a bit more shock obsorption and smoother ride
5.the original engines are gutless so you might want to upgrade that,
6.the engine mounting hole on the pullstart side of the frame snapped
on me,
as it was manufactured close to the edge of the metal frame ,so i
welded a steel washer at that point to reinforce it.
i cant think of much more at the moment
i always liked the shape and look of the tiginics bushpig but i have
to say i have had more issues with this than the koosko.
hope this helps
cheers lee
