one thing you must understand is that they are only machine's and they are only as good as you make it :)
oil changes and a clean air filter! warm the bike up too.....
i have seen too many "retardeds" ruin engines due to not warming them up!
i'm after a new engine and i am stuck between the GPX125 and the lifan 140
which should i go?
the engine is going in my new klx build and i have put aside 400 for a motor,
this will be my track bike.
any other sujestions are welcome
pretty sure they need to build a bike with linkage, that amount of power in a crf style is just retarded (although i want one) you would be better off with that engine in an lxr
already got it coverd, i'll just fill my camel pack with petrol :banana:
i wouldnt put a fully worked engine it, because last thing i want is to be riding a hand grenade lol
first thing, check that there is no over lap between the gasket on the manifold to the head, because i used to have a lifan 125 and that was a problem i found and i just cut out the over lap and it gained a bit more. and also some times there is a restrictor between the carby and the manifold...
