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!
 
Brad you hate these sprockets!. Quick question because I can't remember. Which is larger diameter.325:8 or 3/8:7

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.
