Am I correct when I say the following: You have a stock Blaster-oil injection, 230 main, 32.5 pilot, needle 3rd. Ok, now you remove 20:1 oil-injection and switch to 32:1 pre-mix. Is it right to say your machine will now run richer due to less oil and more gas?

My friend insists that we follow the jetting guides for a certain pipe and filter setup, but with his oil-injection removed, I think that we don't need to go as fat as the guide says because it's already getting a richer mix than it was before. Somebody please shed some light on this!!
Thanks!

 

You are correct. It will be richer with the 32:1 ratio now. But, as always when jetting no matter what the pipe manufacturer or whoever says to jet at you should still do a plug chop and check the jetting yourself.

 

Thanks WyoRider. One other question, on doing a plug chop do you normally get results (coloring on the porcelain) on a new plug right a way or does it take a while to start seeing the coloration?
