if you've ruined 2 boxes you suck with using your clutch..

I don't see what is wrong with making a thread about this??

I barely use the clutch except for going down gears and taking off. My bike seems fine lol

id have to say the zonger 140 is a pretty good engine with a nice box, i havent actually seen one fail yet.
but i seen a few yx140's fail and a sht load of lifan's fail..

hey have you checked to see if these engines have broken engines cases on the counter shaft bearing..

not sure how easy they are to get but the gpx 140 goes off tap in my 2010 pitster x2

 

[sean01]

gpx is just a branded yx engine

Tell my 2 sons about clutches
They have ruined 2 of them previously
They ride the pitbikes like 250 four strokes

 

[no_crf50_here]

They ride the pitbikes like 250 four strokes

and that is how they should be ridden!!!

 

[mattbombers]

but the only diff is a few cc's, well and a couple of other differences lol

and that is how they should be ridden!!!

true that! haha

so what is the difference between the zonga 140 and the yx 140 I thought they were basicly the same? they have the same bore and stroke dont they?

 

[Sabertooth_buterfly]

Does anyone know the answer as I am quite interested to know the diff between the zonga140 and a yx140?
