125-200cc Husqvarna WR 125 (144cc) 2004 problems and questions

Hi! First time writing here. I'm from Finland so please keep that in mind when recommending places or shops. Sorry for the messy writing...

I have had this bike for a quite a while. More hours fixing it than riding it. Not going to write a full history, since thinking for the right terms would take a whole lot of hours.

2014 I sent the cylinder + head to Eric Gorr who was then doing business with Forward Motion. He (or whoever) bored it to 144cc and machined the head. I have read bunch of things about him later. Had no problems getting the big bore set.

Some years later I opened the whole motor and did the bearings, clutch etc. At this point the 144cc kit was still new and not used. Assembled the whole motor and got it running. Not many hours later I felt the cylinder pressure wasn't as high as it was before. Opened the head and noticed some scratches on the cylinder wall.

Immediately thought not going to run the bike before further inspections. Few years later, again thinking if I should do something about it.

So yeah. The question is, where should I send the cylinder for coating and where should I buy a new piston. Any ideas for Europe? I once sent a 125cc sylinder to Holland (if I recall right) and it was okay.

I do have some ideas but this time trying to do as much research as possible.

I also had some problems with the clutch after assembling the motor but will tell about it later.

What sort of drop in compression ? Did you check the squish after rebuild? What thickness base gasket did you use? I t doesnt look all that bad . I would keep running it .

I agree it doesn’t look to bad I would change the piston ring and run another 16hrs

You sure about ball honing a ported cylinder??

Cant imagine that wouldnt beat up the transfer ports, and my understanding is you cant hone nikasil anyway?
