Sorry if this question has been asked before. I'm going to be in the market for a new saw in the near future. Not sure whether to get a 500i or 661cm. It'll be used mainly to cut up hardwood logs and to fell the occasional big tree. I've had a go with a 500i (felled a couple of big'ish outsiders) which isn't enough to form a proper opinion. Although the throttle response was fast. What's the new injection system/electronics like? Not used the 661cm. I owned a ms660 a few years back, if was a great saw - never any problems. Is the 661cm as good? anybody that's using them a lot - thoughts? Pros/cons?

Never bought a Husky bar other than what a new saw came with, which was usually a 15". I used Oregon pro lite 16's for years, not sure if they're called pro lites now tbh

Always been a fan of a 16" bar on my felling saws, really liked them on the 262xp's - still have a 16 on my 560xp. 20" on the next saws up 046 or 372xp. Quite liked a 28" on ms660. All down to personal preference ?

Cheers for all this info Wonky, I'm going to have to learn how to read now ?. I've been looking into some basic small die grinders for the air line - one straight and one 90 degrees for the transfers. Hopefully they'll work, seem to able to get the carbide burrs and polishing stones for them.

Great, thanks Wonky ?

Will have to give mcdizzy a look. No two engines are the same. I may be picking your brains again bud ?

Not quite sure I understand Wonky? Cheers

All this info is great CutterSy, I've got a good bit of mechanical background but not on modifying 2 strokes. So on the stihl ms461, how would you advance the ignition? Alter the key on crankshaft/flywheel? Sorry for all the questions, just really keen to learn about porting chainsaws.

Thanks CutterSy, I would like to port a Stihl ms461 and my Husky 560xp. I can imagine porting being quite addictive, a bit like always convincing yourself you need another saw! Any help and knowledge would be a great help. I'm new to the forum and it's been great having people get back to me with their knowledge and information - thanks again.

Cheers Wonky, really appreciate it. Will look it up ?

It does make sense, got to way the costs against the performance gains. I'll look up the book by Gordon Jennings. Think I'll start by cleaning up the ports and removing any imperfections (lumps and bumps) in the casting. That should make a difference. I'm quite interested to check the squish and hopefully turn down the base of the cylinder (roughly the thickness of the gasket) to see if it raises the compression much and what the gains will be. Thanks again, might pick you brains again I'm the near future

Impressive collection, all ported too. I've read that the 372xp responds well to porting. Hoping to port my 560xp in the near future.
-
Great, cheers Spudulike. Do you get good results, more torque and RPMS? Yeah, definitely a little material removed goes along way. Is there a certain percentage of the bore/stroke dimensions the ports can be enlarged too? I've been reading about squish, have you decked the bottom of a cylinder to raise compression? If there's any books you could recommend, it would be much appreciated. Sorry for all the questions, not too many people this side of the pond interested in porting chainsaws. Many thanks
-
Great, with a bit of luck he might see this post. I'm keen to have a go at my own. What models have you had ported? Did you get good improvements?
-
New to the site. Just wondering if anyone has any information on chainsaw porting? Not for a racing saw, just to get a bit more performance out them. Is there any guidelines to follow on how much material to take out? Got quite a lot of mechanical experience, just not on porting. What kind of small die grinders do people use? Hope I've posted this in the right place, new to the forum stuff. Thanks in advance
