Well I don't put a gallon in for every 100 gallons of fuel but I do add it in

i think a gallon per 100 of gas would be good.

Cool. I would think upper cylinder wear, ring seal, and valve seats would benefit.

Transmission fluid works as well. It's cheaper than 2 stroke oil. one thing you have to look at with adding anything to the fuel is cost. A 100:1 mix is going to take a gallon of additive to gas. If you have twins its x2.

Tim a competant cylinder head shop charges $10-$15/seat labor to install seats. The cost of a seat is right around $15/seat. If I competant shop does the work there should be minimal if any blending that needs to be done. If you just did the exhaust your into it for $250/set of heads. That's $500 or $1000 if you want to go all the way with its. Of coarse you will need a valve job. But you should need a valve job anyway. In the grand scheme of things it's money well spent. Sometimes you have to sit down and look at where to spend the smart money on the project rather than just spending money when the money isn't there.

The seats are beat up a tad not sunk into the casting, I won't post anymore so you won't have to read it... Whatever.... I can't change everything every time something arises, I know 3-4 guys without the issue so it's not a GAURANTEE this will happen, and I am already too far into it now so whatever, like I said before if you want to send a check to pay for it send it.... I have spent enough, if I have issues again the whole thing is going to get parted out so I am willing to just move on.

Do everyone on here a favor don't B I T C H that you have to change your seats later. If I remember they where already sunk. Only reason I siad to wait a month is the fuel cost will pay for the material and the job. Everyone try's to help others on here.

And more ports irk since it's all done... Plain and simple the heads are going to be how they are. I just can't go backwards again. Many guys have no issues and some do... So it is what it is.

Not trying to be a jerk about it but I don't have endless money I have way too much into this as it is. Going to be a divorce eventually.

Tim, You do what you want, but if you took your motors apart and don't address everything that doesn't look right why would you think the problem would correct itself.
