My HJR ported jug.

Ken custom figures each head based on MSV calculations... so just copying a head built for one engine won't simply work...

That HJR portwork looks mean. He cut the transfer divider down WAY low (lower than I would for a trail motor) but didn't take the intake area or transfers out too far which should help some with the torque.

Overall the job looks quality and should be a screamer!

I'm gonna chime in on the carb issue... A 39mm PWK seems a little large for anything but an all out drag quad. Most will recommend a PWK 35mm for anything less than an all out drag quad even stroked 240 kits.
 
to me it doesnt seem like a good port job for a blaster motor is what im getting at. i mean all motor guys have their ways of doing things, some work better than others. my next motor will go to flotek to see what he can do. although its for the wife and will not be too wild...

This just being my thought, But if you have it ported to a stroker crank the porting won't be ideal for stock crank. Not that it can't or won't work. The other thought is how the porting is done to rpm performance, If he recomended a 39mm carb with a stroker crank. I'd think the tuning would be mid to high powerband on the porting.
Manly cause low mid tuning usually does better with smaller sized carbs and mid to high tuning does better with a bigger carb. If you ever looked into road racing they use large carbs on the bikes for high speeds for max rpms, but tend to be peaky in the powerbands.
 
i demand inside shots of the exhaust port!!!!
looks good to me the problem with pictures is you cant realy see all angles and aspects.
only get an idea of what was done/changed
 
ok that makes a big difference, he def opened em up, but still im not that impressed with his work like when i see a flotek or KOR motor. but to each is own. it takes skill to do what these guys do.
 
Ive looked at some hjr work on blasters and liked what i saw. i even saw some crazy "worm" ports in the top corners like boysen ports he did on one. The exhaust looks wide and square which is great. I personally like how he cut away the cylinder on the transfers so that they are wider in the opening. they appeared to be lower (while loking at the bottom) than the sealing edge of the transfers. this is how alot of performance dirt bikes look. On another note i didn't see any boysen ports in the intake? Either way it looks good and you'll smile from ear to ear when u crack the throttle!
 
i think it looks pretty good the exhaust port is great thats a fact
the intake isnt the prettyest thing but thats not where the power is realy made from what i have read/heard im sure you willl be 100% happy wiff it
 
Re: Bly HJR ported jug.

I'm going to stick with my 30 for now. My next jug is going to Ken. I know it will be rite then.

that jug is right and will make damn good power.... HJR does awesome work and honestly knows his way around a blaster motor just as much if not more than ken does

he might of mis-spoke with the 39... however thats still not to big with a stroker motor

how do you know its not a good port job? have you been doing this for 20 plus years?

also, are you implying that flotek doesnt know how to make good power?

come on guy, everyone has opinions... yours are just rubbing a little to much to the kenny side. hes not the super duper best in the business... yes he makes GREAT power but still, there are betters.
 
I don't know alot about what porting should look like but I do have trust in the guy. He was a very nice guy to talk to and did a great job for me. I know this guy has a great rep when it comes to motors.

if everyone has opinions then dont rag mine. its an opinion and the reason i picked ken is because he has done probably over 50 motors on here and not one has been spoken bad against, and no i was speaking about sending my jug for my other bike to flotek to see what he can do, im all for new people coming around, just from what dakota said about not using a carb less than 39mm??? thats a little much for a +3 stroked stock jug. so dont start talking sh*t to me. and show me how its possible to set a jug up for a +3 and stock stroke because me and ken had this conversation when i was giving him the info on my motor and i told him it was a +3, my jug is set up for a +3. u cant do both and if u think u can ur a dumbass and so is the guy telling you, once ported for stock stroke u cant put a +3 in it unless u up the rod size to 115, then u can redo the ports, head etc, not going into detail but pm me i will be more than happy to tell u all about it. im not going to get into a fight over some dumb sh*t, hes been doin it for 20 yrs so he MUST know what hes doing...


dakota i hope that motor rips when u get it runnin.

listen, if you run the spacer plate, you can have a porting that can be used with the stock stroke and a +3... he however probably just cut the exhaust port higher to get a bit more top end with the plus 3 since you will eventually have it (also strokers like a bit more exhaust port duration). it will run great with the stock stroke but maybe a lot more top end oriented.

there is no need to get your panties in a bunch, i know how these motors work too brotha, so dont point the newb finger so quick ;)
 
im just stating the obvious bro, i didnt like what the guy was tellin dakota, granted i wasnt saying he was a bad builder, i would never use him because the ones i talk to i want to know exactly what they are doing with my money especially motors are not cheap. another reason i went with ken oconnor i called and talked to him, he had no secrets to hide told me what he was doing how he was doing it, i talked to him on the phone for almost 2 hrs about motors and sh*t and i learned some sh*t too. thats all im sayin. if a guy doesnt want to give his secrets out thats fine but i guarantee i would never be able to copy kens work.

Holy exhaust port umm thats why this guy recomending 39mm carbI:I
 
the entry to the transfers looks a little rough, but i'd bet that it'll rip. 39mm seems a little large, but i've had a 36 on a reeds/fmf pipe motor, it lagged bad on the bottom, but if i would've had a higher rpm pipe it would've ripped in the upper rpms
