ms 261 8 tooth sprocket

[djmac321]

I got a 261 just wondering what would happen if i put an eight tooth instead of the seven....help me out guys im a newbie!!! only got a 16 inch bar!

It would probably bog down sooner. What are you trying to accomplish?

 

[djmac321]

i want a little more chain speed....sorry im just getting greedy!!!

I think you will be disappointed.

A quick look at these shows the 3/8x7 as about .040 ~ smaller then the .325x8

Just jump right to a 9 or 10 pin you'll have even more chain speed. Steve

I ran an 8 pin 325 on a mildly ported Echo CS520 to good effect with a 20" bar in hard wood.

Just a little smaller, and the higher chain chassis of 3/8 partially compensates.

.325x8 may work well on that saw in some situations, but certainly not 3/8x8.

Not a lot of money is involved, and it may be fun to experiment a little, comparing .325x7, .325x8 and 3/8x7.....

If you ever port the ms261, then it will run great with .325*8 on a 16" bar, That's what I have on mine right now and it will cut large rounds buried with plenty of torque for the 8 pin.

Iv'e just installed a 8 on my 261 cm with a 3/8 set up 18" bar. I'm running full skip rmf chain. With the exhaust mod. This saw really performs well over the stock set up. It now clears the chips very well and no pinching . I thought It would bog for sure, but the saw has great torque. The full chain was a okay the 8 but would have been much better with a 7. going to the skip chain with the 8 made it so you could even push into the wood without bogging the saw at all. Just to compare I have a 7 pin coming to try with both chains next week. No other mods as of yet.

An 8-pin 3/8 rim running regular 3/8 is WAY too big for any 50cc saw, ported or not.

I gave up on 8 toof sprockets.
Even on 70cc + saws.

I agree. Only the strongest 90cc or bigger saws are really better off with an 8-pin rim, IMHO.
