rosey,weed here man.
ya still having woes lad :shock:
i thought rosey should be all rosey by now :mrgreen:
i will start on the easy one first,as why its shooting flames out the exhaust & running like $hit.
if it shoots flames out the exhaust,its running very lean.if its shooting flames out the exhaust constantly,the jetting is way off.if its doing it inconsisently/randomly its either the float or needle sticking shut,but my bet would be on $hit in the carb,either in the main,pilot or needle or in their passages.
have you got a fuel filter on it?
have you unscrewed the fcr's drain bung & had a look if there is any crap sitting in the bottom of that?
you only have to have the slightest bit of crap sitting in the bottom of that, & the main can suck it up & drop it,suck it up & drop it,if you know what i mean.
have you talked to john about how much metal is on the drain bung?
dunno,sounds a bit suss to me.shouldn't be that much.
what did it do last time? did it stuff the bore?
what you don't want to do, is stuff the chrome bore,piston & rings.very expensive as you will know.
i am REAL suss on the bearings in these things, either moving in the cases or moving on the crank.
the bearings are not the problem,its the way they are retained, press fit on crank & case is just not good enough.
next rebuild i will be retaining both.
my crank end float goes from zero cold start up to .4mm when hot. it wanders.
bushy has also noticed the same thing.
pull the magneto cover off & see if there is any float there.
if there is none,dont ride it.get back to me. & we can go from there.
