Huh? Are you trying to ask if you ran 20% last year can you switch to 30% ?

No problems

No, for some strange reason it didn't allow the whole post.

Here it goes again:

I have been running a WS7 for the last year and a half, aprox 5-6 gallons. I decided to pull the motor apart for a little PM, and noticed a proportionaly large amount of carbon build-up just on the top of the piston. After some carefull cleaning I also noticed two very small nicks in the top of piston maybe from a coil on the plug. I was wondering what caused the build-up ie. tune, fuel, wrong plugs, and if the nicks in the piston itself would hurt performance or tune. I have been running OD 77t and 97t plugs. The rest of the motor is basically spotless and it ran fine prior to tear down.

Thank you for the quick response to that partial post!!!

Representin !!!

Nice Paint Qmartin.

cool decal too Monty

sweeet!!!

Monty, when do you think you will start your breakin service again, also I assume I would send it with the clutch etc installed. I have a plus 21-5k that I think needs your touch after my last experinace with a p5x.
Thanks

probably whenever the rain stops and the temps pickup around here

i didnt realize how many engines i would run in until i stopped doing it for a while

Thank you, I will leave it as a paper weight for a while then.

Monty..what is the main difference between the new P5 T and a Plus 4..on the track. got a race coming up and i want to run the p5..but than again the plus 4 is well...a PLUS-4.

5 port has a powerband that the 4 port lacks , more raw power . depends on what crank the 5 port has in it as to how much powerband also

p5xlt / 15009t or 15007t works just fine

well i was referring to a bone stock P5XLT

is the 15009t what the new p5 has in it?

No, 15009. The tuned stuff costs more

gotcha..
