Hello fellow RCers. I was wondering if any of you have ported your head on these motors. Thinking about giving it a try on my motor since I have it apart due to a blown head gasket.

Can you post pic of your port job. I am going to give it a try. Never ported a head before on a two stroke.BertR said:Hahahah that's funny you ask I just ported my stock head tonight after my intake gasket and head gasket went belly up at the same time. Since it was apart what can it hurt lol. if it don't work OBR will head will.

Larry I see you did all the porting on a 4 bolt head engine. Would it be the same on a two bolt head. Also did you you anything to the bottom end to get to the 18000 rpm range and if you can upload some hi Res pic that would be awsome. I am thinking about doing some work on the piston also.larryo said:Bertr can't run the cars now it's winter here.But with the boats they can get up and go,my engines hit the upper 18,000 to mid 19,000 rpms.The best mods are the piston and eye brows in the runner port.You can remove 2mm off the skirt of the piston to keep the intake open a little longer for more intake of fuel.
O and if you going to lighten the piston inscide don't remove the alum by the piston ring pin,if you do you might loosen the pin and kill the head when the ring starts to move out of place.
If there is any more Q just ask i'll try a tell it the best way i can on the forum.My spelling ect is the sh?t!. But i can upload pic in more detail if need down the road.

No problem about the hijack you may ask question I don't and get answers that will contribute to the topic. So no harm. I will be looking forward to hearing how it runs.BertR said:Hey Charlie... I will find out tomorrow how the port job works out. This is my first attempt at it also there for I cant say what I did until I know that it was a success . I will keep you posted and sorry for jacking your thread
creepingcharlie said:Checked out your vids. Your boats run good. What did you use? A dia grinder or a dermel? Also for the carbide bits did you use the longer shank ones like you would use for larger heads.
