Who ported your cylinder? and how do you like the results?

Recommended Posts

i did, its what i do for a living here in Phoenix, really woke up my 04, more power everywhere and much lower EGT's which ended up resolving my detonation issues before i ported it. i usually charge my local customers about 400 for porting a two stroke cylinder+head mod.

thats a bit to high in price for me, but thanks. just curious, whats EGT's? and how do you hear the pre-ignition detonation on these rm,250's ? thanks

you might want to check out Eric Gorr at forward motion i think it looks like he'll do it for $225 or so. mine was done when my 265 was put in and i love it.

05 RM250 (265 now)

Ported for more power all over.

It is set up for pump gas but I run a 50/50 mix of 93 ethanol free pump and 110 leaded race fuel 32:1 premix.

I run stock gearing which is 13/49 I think (can't remember for sure right now)

EGT=exhaust gas temperature. that price usually includes a top end build so if i were to just get a cylinder itd be less. id only ask that you send some pieces of solder that you took squish measurement with so i could mill the head to spec(or raise compression if you decide)
