[MRieck]

Very nice work Mike....

Mick....I still have to blend those seats.....small potatoes compared to the 750. I'm telling you....this thing will be bad.

[MRieck]

Very nice work Mike....

Thanks . This thing is fantastic for 550's willing to go the extra distance.

[srbakker]

I can not wait to get my stuff in the mail to you...

[Bill/BentON Racing]

Sweet! I can't wait to RECEIVE Mike's work back!!!!! Like a kid on Christmas morning!
NICE WORK Port Master Reick!!! You are coming to Valdosta....Right? I need gaskets also sir,.010 base please. PM me on your big engine.Thanks,Bill

[Retro Rocket]

Very nice work Mike....

Thanks .

No worries Mike, trying to raise more funds for one of your "BIG" 750 heads....

[RAFster122s]

That's gorgeous work Mike!
Is that with 1mm larger valves and a Stage III head port/head work?

[MRieck]

Yes. The intake guides have also been cut down and tapered. Intake seats are opened up to .9 of the valve OD. the exhaust seats opened up to .85   

[voxonda]

There is just one thing very wrong about this head....................................................................it isn't mine!

Outstanding work, Mike as usual!

Cheers, Rob

[Jim F]

and all of Mikes heads are a work of "very good working art"

Nice Mike

right now dont shout at me .... but , how the hell do you look at a cylinder head and tell if its ' good ' or not ? 
ive seen plenty of very shiny ones that have made rubbish power and ive had a few that looked nothing [ ten kate ones especially ] that make great power
i have no doubt this head will work well , just wondered how you all know by just looking .

[kmb69]

Absolutely beautiful, Mike.

That port design is basically what is in Brent's engine now minus the OS valves. He is making good power as evidenced by dyno #'s and his winning ways. There is room for improvement which is exciting.
 I agree with your statement Simon...I have seen the bling and some crappy #'s. This is especially true for one brand of ported Harley heads. Big name but various "problems".
 The head in the pic does have some basic improvements such as removing that restrictive guide boss and flattening the port short side and getting some volume in there. The real improvement is increasing the seat ID. That is were you can pick CFM quickly.

yes mike , you know this head will work because you have seen the flow figures and have had previous experience with similar heads .
it just seemed odd that other people can simply look at a picture of a head and say ' thats good ' if that was the case you could throw your flow bench in the bin and just post a few pictures of your heads on the forum , the experts could then tell you which ones are good and which ones are not .  think of all the time that would save you mike !

I'm sure that a lot of praise for Mike's port work comes from the immense respect he has earned over many years of perfecting these heads. I too may not be an expert on visual assessment of the work pictured here, but it has me striping my spare head and boxing it to ship.

How long is the wait time for this level of work?

[bwaller]

How do you spell wood? From my b-berry I can see what you described Mike, awesome.

Good and bad today, wonone heat then the skies opened into a two hour deluge and the rest of the day was cancelled. Horrible. Bike isa tank, rode out a huge wheelie on the start andscared Deb to death!

Big day tomorrow.

Cheers

[TimV840]

Mr.Waller didn't mention the 1/2 lap lead he had on the field(me included) in the heat race! Hopefully the skies stay clear tomorrow and we can finish off our season on a positive note.

About 12 weeks Jimmy.....I am very busy with some outstanding projects. My 1000cc is finally only days away from starting. Only 2 years in the making. I feel guilty working on it to be honest but I have to get some riding on it this fall.

[RAFster122s]

I could see some of the mods Mike made before he mentioned them and have read a few threads on the board of Hondaman talking the thread owner through his guidance on what worked well for the 550.  I respect Mikes work and his reputation and Brent's recent track record was through part of the benefits of Mike's head work. So, while I don't have the skill to look at a head and know if it will produce good results I trusted Mike when he said it was good. From a artistic point of view it is beautiful workmanship.

I would imagine Mike has been through some heads that didn't work as expected and were disappointing.  What works on a SB Chevy doesnt translate to a MC and some things do.

But numbers and big numbers don't always translate to great results, as it is part of a system and everything needs to work together to create a winning formula. Mike has the knowledge to provide that guidance I think.

dont feel guilty about that ,  just say to your self your doing product evaluation for your customers .  will this be the first of the 1000's to be run mike ?

If it'd look good on my mantlepiece Simon, it's good! 

[Bill/BentON Racing]

Good enough for a 100+ RWHP!!!!!! .....stay tuned! Bill

[cb550fcafe]

WOW Mike, looks better than the first head on my other bike and that thing flies. No doubt this next bike will be very fast! Its definitly port porn.

APE has the crank for lightening and cylinders for the big bore JE pistons, web 58b cam, adjustable cam sprocket, CR 29's, Yoshi header, ARP studs, Dynoman clutch, Dyna ignition and several other little performance items on a CB550 that should weigh in under 400lbs. I can't wait for this one to come together!!!

Not that I'm an expert, but CR26 carbs might be a better fit.

Nah Jim, they run 26's on hot 400's, i know a lot of guys here use 29's on their 750's but a good HIPO 750 can run 31mm CR's easily so the 29's should be just right for a hot 500-550.

My 500/4 racer and i believe that also Howell's, run CR29's and that's with just 500cc, no big bore. That said, i do think that for a street application CR26 or VM26 (actually 27) are a better option on a 550/600

[cb550fcafe]

I hear you on that FJ. However my other MRieck head, big bore, web cam CB550 has CR 29's and it runs awesome. I bought a set of CR 26's after we talked from Power Barn. I took them off, performance was not very good and they were way too fussy, I couldn't make them work as good as the 29's.

Incedently the new 26's are on the bench if anyone is interested. You need your own spigots though.

did you ever dyno that motor?

[cb550fcafe]

no, I haven't. I do want to but I know the number would just put me back in the shop trying to push up a number that doesn't affect my fun factor.

I should do it before winter. The clutch has some trouble holding the power in 3rd gear, tends to start slipping 1/2 way through the pull after I've been beating on it. Barnett clutch and springs with shims added to the springs, regular petroleum oil in crankcase. Sounds like a barking dog when I clutch out now and then. But this is a different problem for a different time.

[RAFster122s]

New steel discs in the clutch w/Barnett clutch discs and springs?

[cb550fcafe]

yes RAF, all new plates, frictions and steels, new springs also. I guess I'm just making too much power. hehe

[MRieck]

Bead blasting the steels can help with that Kevin. Not a sure cure but I have seen it work. To bad there are no double steel plates like the later K/F's had (spring washer in the center). Those work well.
