Nice! I'm look'n forward to your results. I've always left the motor work to the pros. LOL

I'll be down in the work shop this weekend,and i'll take some pic and point out were to remove metal and about how much.

There is something about taking a engine and making it work better by your own mods.But OBR does a really nice work on there engines,and i can't take that away from them.

Ok!! she is all back together and 3 heat cycles and all torqued down This thing is pissed off and I haven't even tuned it yet "TX battery was dead". Just so everybody knows Larryo knows his shit!!!! Thanks for the pointers and sharing your photo's.This engine work was fun to do and now I'm ready to find another engine to get a little more aggressive on the mods. I shot some video sunday just before the tear-down so I can do a before and after in the same place. I will upload some pics in my photos of what I did to the beast.

Thanks creepingcharlie for letting me have a piece of your thread

Awsome job dude, I just think I would feel better about myself if I did "that" porting and the motor is screaming now.....but the pros do my porting till I come up with the courage

That awesome man. Glad it all came together. Can't wait to see it run. And no problem for sharing the thread. I will be posting my progress of my port job soon.

 

[creepingcharlie]

Well I got ants in my pants today and stared to port the head at work. Where I had air and a die grinder. I tryed to follow what was posted on ************** forums. I got interrupted a few time which didn't help. I will post some before pics and finish pics. With what I was trying to accomplish. As the pic will show I got a little happy removing material. Also you will see you need a steady hand and at time I did not.

 

[creepingcharlie]

First pics are of head in stock form.

 

[creepingcharlie]

 

[creepingcharlie]

Here is the start of the eyebrow porting and where I should off stoped. Also the star of the transfer fins cut down.

Pic of me not not knowing when to stop. See the hole where I took to much out. also you can see I ported the intake runner.

 

[creepingcharlie]

Here's the exhaust side. With some blending work. Also the exhaust runner ported and semi polished.

Now a top view of the finished job. As you can tell I am far from a professional proter. But for my first temp at doing this I think it came out OK.

And for how I fixed the hole. I got some steel apoxy and filled it in and re blended it. Hope it works for a couple of runs tell I get a new head. It hard to tell but if you look good you can see the different color where the hole was.

 

[creepingcharlie]

A couple pic of the intake and exhaust runners.

That's all for now.

 

[larryo]

HI how low is the two thin runners? you can only go down about 1/2" and the the intake port looks good.but don't take any more off that tit were the pin in the piston is on the intake port.and do you have a pic of the exh port roof to post up?

 

[creepingcharlie]

I went a little less then half way down the the fins. I will post some of the roof of the exhaust port.
