anyone ported or had poring work done on a 661

[littlerob]

right so had my 661 a little while now well about 9 months seems to be a little underpowered personal to me. So anyone had there 661 ported or got more power from it in some way or another

Have your dealer run a diagnostic maybe?

saws been looked at and runs exactly how they supposed to and to be honest its ran the same from the first tank. but just seems a little slower in the cut and lessy grunty than a 395xp ported. So it could just be me feeling like its not performing as i would hoped

[Rough Hewn]

My 661 was a bit weak until 10-15 tanks.

Now pulls like a fast train.

Never tried a 395 but I can out cut my 880 in 30" oak.

Have you thought about changing the rim sprocket ??

I have a spud ported 460 which is stunning and have had my 661 about a year and have felt the same as you. It has the torque for a 36 bar when needed but if you aren't in a rush.

 

Feel it should run a bit better, however it's probably set up so that runs for ever not sure my 460 will (no offence spud I am delighted with it still).

[Rich Rule]

A couple of the 661's I have used in the past have got sigjificantly better after about 10 tanks.

 

I have a 660 that Steve ported. It cuts like stinks and is very loud. Not sure how the 661 would respond.

 

Do the 661's have the computer tuned carb? Would that create an issue with tuning after the porting work had been completed?

I have heard rumours of great success with putting an 066 carb on them - interesting

there got to be something to try and get a bit more from the saw. the saw had done three 5 litre cans of aspen so u would have thought it done its bedin period and should open up a bit more on power but still runs like day one

H what size bar and chain you running on it and what you cutting with it ? And are you felling ringing up with it.
