Yes i cleaned brake with brake cleaner and with wire brush. The caliper i just used brake cleaner because it has paint.

[jonne123]

Bought blinkers and testing the wire lenght and fitment.

Cooland leaking need to fix that.

Why there is 2 wires to park bulb? It works but is park always on okay?

Dissambling horn for painting.

Painted

So i had little worn rear tire so this happened... little backfire also. https://www.youtube.com/watch?v=GruRc--3zNA

[jonne123]

So i had engine failure and said what the heck i will rebuild it. and tune the bike up. Pictures coming!

[Calum]

Wow, why did the engine fail?

@Calum
Check out his pootube vid, then ask yourself why you asked ...
Sorry, did I miss your dry humour?

[Calum]

@SpookDog no I did see the video. Still though, a little burnout never hurt anyone

[jonne123]

So basically i was just revving the hell of it for about 20 seconds went driving and felt weird. Engine stalled kickstart stuck.

So i opened the engine and there was bearing pieces over piston so rod bearing failure. There was sand in engine via bad air filter from previous owner. Also the piston was ridden about 1500km and the ring cap was 0,7mm on the top one and 0,5mm bottom one. And the needle bearing was shot. So the engine would have failed eventually. I think i know now what the werid side noise was.

Is called seizure by heat or lack of oil. Or screaming from cold start. Or all of the above...

“There was sand in engine via bad air filter from previous owner. “

Bad you never checked as well though bud (the filter) bike stuff 101

The rest is lost in translation, to me.

[jonne123]

Well it had rebuild top end and i changed the filter right away but didn´t realise that there was sand in the intake until month ago i cleaned it. Also the engine was making weird side noise probably from crankshaft. There was oil and mixture was rich.

@Calum
Totally! I like to burn out my back tyre though. Not my engine ...
