M-tronic's & ported/modded, muffler/carb mods, etc.

[michaelmj11]

The only thread that showed up when I did a search was one or two posts in "Clint's Hybrid"..... so:

How does m-tronic's affect porting/modding, and visa versa?

#1.) If the muffler is the only thing modded?

#2.) If the only thing done was removing catheters?

#3.) If the carb is the only thing modded?

#4.) If the whole sha-Bang is ported?

Full Porting + muffler mod + timing advance doesn't seem to be hurting my tree monkey 661 !!




Stock 661 41" bar .404 RS full comp 118dl (Times are in the title of vid.)

TM661 41" bar .404 RS ...same chain.

Stock 661 41" bar .404 RS full comp Noodling oak

TM661 41" bar .404 RS ...same chain Noodling oak

do you use it for work, or mostly play? and how long has it been ported/modded (i.e. how's the longevity looking)? I have a 661 but I suddenly feel inadequate and ..... stubby... (see profile pic....)

I do have a 36" for it.
