13.5:1 piston question

Do you have to use race gas or some additive to run with this piston. Im ready for a new piston and I was wondering if this choice would be right for me. I dont race but I ride mostly mx tracks...Is there a noticable difference over stock? I'd rather not be restricted to using race gas only...but, then again if the performance difference is signifigant maybe I'll give it a shot.

Are you happy with the performance of yours?

Thanks

Mike

No you don´t need race gas.

I just installed that piston and it works great! :cry:

It has a kind of 2 stroke wannabe trottle snap, it feels much more agressive now than before. I also installed a complete race DR.D at the same time, that might have something to say too. But before i had a WB e-series and it rides way better now. All i need is to have it rejetted, the main is to small now.

Good luck :cry:

Just curious since I run the E-series WB pipe also...how many discs did you end up with for the best performance...I have 12 right now and it seems pretty good

kinda loud but not terrible...

BC :cry:

Mine hated pump gas. It would spit and sputter. But when she ran on Klotz she screamed! I would only run race gas!

BC: I only used my disc when the dnr was checking other then that I removed them and rode without them. They restricted way to much power for me.

It would have been a whole lot cheaper to just rejet!

I think if you would have taken the time with jetting and disc selection you would have made more/better power with the discs installed.

Take them all out.. Mine is running a lot better without. :cry:
