I followed kens instructions on getting my jug cleaned up and can't wait to get it all finished and bolted up. This does take a long time with a dremel tool but I will put in as many hours as it takes to get a few pony's

I have the jug mostly cleaned up, alittle straightning to do. I couldn't leave those big flat spots in the top corners.

this will be a mirror before I bolt it up. i have an alluminum pollishing kit

transfer ports are def the hardest. I have to order some longer bits. by the way I really like using the drum sander on the larger ports it works really fast you just need a lot of replacement sanding pads. lol
Thanks a ton ken I:I
 
lookin good bro, where you talkin about polishing, ken only does the exhaust port, the intake and transfers get sand blasted, not polished, to help with fuel (atomization) ?????
/\/\/\/\or sumthin like that,
 
Lookin good. Kens contributions here are a gift that keeps on giving. Hate to jack the thread but I'm curious about the holes in the top corners on the intake side. Did you drill them? Do they go to the transfer ports? Is the purpose to increase the flow ? Redirect the flow? Both? Sorry to sound dumb and ask so many questions but I've seen these in pics before and would really like to know.

Thanks
Otis

I know not to polish the intake thanks though. some people might not know. The holes do go through to the transfer ports. I kind of came up with that on my own. I have seen a lot at the bottom of the intake port but while looking at it I thought those two huge flat corners at the top looked like they would stop a lot of flow. I had an old jug that was ported a bit that I used for a map of the intake and I just applied kens instrucitonal to it for some rules to go by. but I take full responsablity for the holes I drilled. Good or Bad. cant hurt too much I wouldn't think

you just pretty much changed your port timing...

those are boyesen ports and they are supposed to go on the bottom of the intake, ill be surprised if it runs good...
 
I thought about doing the same thing but after I stuck the piston down there and looked at how close the ring ends were going to come to the holes I decided against it. It was just a little close for my taste.

How would he change port timing? Port flow, port direction maybe... but port timing? There is already a port above the intake window to push charge on top of the piston at TDC. As long as his holes don't enter above that, I don't see how he's changed his timing.

i agree, he just made the intake charge enter the chamber faster..
 
that's what i thought too freek. but i guess we will never know how it ran bc that is the jug that took the beating of my lower end rod bearing coming apart. so it ran like ass LOL. that was a bad day. all the work i put in was distroied bc i didn't listen and replace my crank. I made it like half way around my block and all sorts of really bad noises happened. One of the many reasons i preach listening to the advice given on this forum.

man this is an old tread
 
I didn't look at the first couple of dates either... but it would be nice to have a long term update on some of the engine work that people experiment with.

Also, I meant BDC in my previous post... I figured it would look silly to change it after it had been quoted but after I reread it I caught the mistake.
 
I really looked at those corners on the top end that's on my blaster now. I really thought about drilling a small hole between the transfer and that corner.

I might try it later unless it's dangerous. Someone chime in...
 
you have to make sure of the angle you are drilling isn't going to go outside the jug. it is a tight fit but i was using a 1/4" bit. i actually roughed up the area on the outside of the jug and added some jb weld to it just for some peace of mind. I didn't hit the sleeve at all. I think that jug has some life in it. maybe i can talk my buddy into runnin it on his blasty. needs a bore though.
 
heres the cylinder that batt did with the boyeson ports in them.....they are also in the motor that i used for awks ride that he did....and im sure the other guys can tell ya how she ran bahahahahahahahah

....whats taken u guys so long ahaahhahhahahahahahah
