Update....
I got stuck into the bike yesterday morning to see if i could get it fired up for the first time.
The engine in this bike is out of another that i thought was the better of the 3 i have.
Filled engine with oil,mixed some juice @20:1 and kicked it over.
Wouldn't fire up with the plug it had so i used the one that came with the bike and i know worked after trialling the PE175 ign/stator set up.My 250 f/wheel had done the usual trick of having the magnets let go.
4 or 5 kicks and it fired up with the usual 2stroke sound and plenty of smoke
and idled pretty much after taking the choke off.
That was all good and even the headlight was working
.
Fired it up again for about 1 minute and killed it to go over the timing and tighten f/wheel nut...thats when i could feel a rough sound coming from the crank area as if it was dry...dead sure i mixed my fuel.
Then i rotated the countershaft and it had the same sound
.....strange i thought,new oil in there as well.
So this is how the biked looked last night
Pulled the engine down this morning and found very fine dirt/sand throughout the bearings...couldn't see it,but i definetly could feel it.
So this is how this engine looked this morning
I decided to shelve that engine for now.
Now was the time to check the engine that came in the "bike from hell"
When i got it i was told it sat in a paddock for about a year which didn't worry me.
I couldn't even kick it over and had a quick look at the piston in the exhaust port which looked like it was seized.
Decided to pull it down to see what was salvageable and to my surprise the engine number is 40 units newer than the engine the bike came with,which makes it closer to the frame number
Another surprise was that this crapper looks to have done bugger all work in its life.(apart from the well used sprocket
)
Infact piston was not seized but rusted in the bore from sitting in the paddock.
After taking the flywheel cover off,which i'd never bothered checking to see what mess was in there when i got the bike as the wiring had been cut everywhere...i found a perfectly clean and new looking flywheel with magnets intact and also the lighting coils and stator/pulsar in very good condition apart from the chopped wiring.
Even the dowels and studs look clean/newish and pulled the clutch cover off expecting to find water/rust/dirt...nope all good in there too
Cleaned out whatever was in the crankcase and g/box,oiled it up and its all quiet and smooth.
A set of rings and a quick clean in the bore only where the rings were stuck and i might be lucky
to use this engine....
cheers...mario
