is it even worth doing?

will it effect reliability?

i was thinkin about doin this, but im not sure, could anything happen to the motor? thanks

Well, timing can and will effect the powerband. There are several threads about advancing timing and the its interaction with compression and other things. That being said, there was one in a motor that I had rebuilt by a very reputable/legendary tuner that took it out and said that on the 250r, he didn't feel that it did any good. So I have an ESR version of one of those for sale :-)

I think all your questions where answered on the other thread but anyway,-
-That ones is NOT adjustable. It has +4 degrees & thats it. You cant "dial it in" . Just 1/2 a degree of adjustment + or - can make a difference so I wouldnt bother with that one. (All motors are a little different due to the way they are set & the mods they have too). In some cases you may need to retard it instead of advancing it.
-On a stockish set-up -probably not
-Yes youre reliability can be compromised when you advance too far + !! Otherwise NO. (better know what youre doing-as Red Rider said. A little at a time going advanced +!!!
-Like I said, theyre not as cheap as they used to be (R.P.M.unit)

If you have messed with port timings, stroke, spacer plates, it can help. If you have a basically stock engine I would not waiste the money.
