Re: 915cc cb750 cases together
man the motor looks great! love the silver on the heads to tie in the tins... great work man... glad to see i am not the only one to sue that wheel chuck! hahahaha actually pulled mine and my brothers off yesterday and stripped and blasted them. i am going to coat them red to match the lift... anal i know

Re: 915cc cb750 cases together
* side note.... sorry off topic... i just stripped 2 down and coated them last night... if you have them on your trailer be sure you are checking the welds!!! we have had 3 go bad... they rust right though on the upper support, even last night i coated mine and my brothers to match the lifts (pain in the ass by the way) but we used his 2x's to take our bikes to FL... it was rusted right though i had to re weld it before coating

The engine in the back is the original 836 with APE head. I am keeping that and looking for another 750 to put it in. As for the paint, I really liked the look of the old paint to so I don't think I will stray to far from it. I have never had a professional paint job on a build and felt this bike deserved it. The guy I am using does a great job and knows how to keep a good flow on the old bikes. http://www.meticulouspaint.com/ I am just lucky that he lives with in driving distance.JRK5892 said:
Hi Tweaking,
You have a really good looking engine build. It definitely is ALL OUT!
I actually am in the middle of an almost identical build _Mr Rieck's stage 4 head, APE super crank (w/ Carillos), CCC HD primary chains, big bore, etc.... I personally understand the cost and love required to make this happen.
I am interested in how your experience went with having the rockers hardened. Can you post some pics? Did you lighten or smooth them up also?
I can't wait to see/hear the engine completed. This project certainly will be among the top CB750s in the country. Kudos to you! I am also following the SOHC4 thread.
EDIT: is that a "GORDON'S" frame mod kit? If so, I don't need to know if you like it. If it is a different kit, please elaborate!
peace and grease,
Fang

Thanks for checking out the build Fang! I was on the fence regarding the Carillos for my "street build" but man they are beautiful. I am happy with the super rods. I set out to build a bomb proof big bore engine for street use.
Here is a pic of the hardened rockers. (not mine, from a 550) I couldn't see putting in the old rockers. No lightening, just smoothed up and then hard welded.

oh my goodness this is like free sex. this is exactly what i want done to my 80 DOHC 750C.
I've been wanting to do a complete total rebuild on my motor for a few years, never took the leap (dont know any bike mechanics, local bike shops charge $85/hour for models older than 1990, and the twins killed my pocketbook).
if you dont mind me asking what do you have wrapped up in the motor? and when can i send you mine

I just found this thread as somebody brought it to my attention. Hmmmmmm....a recent LSR CB 750K head I ported..... .100 36CFM .200 53CFM .300 74CFM .400 81CFM .500 (who cares) 84 CFM. All @ 10 inches. What is Berreth's best? I am sure I have him by about 5 or 6 @ .400 and God only knows at the low lifts which really count as they occur twice in a cycle.teazer said:

An old thread revived. Why are those low flow figures so low? Our 240cc CB160/300 flowed 59 at .20 and 79 @ 0.3". I didn't do the porting so I take no credit for the numbers. I'm pretty sure they were at 10", but can't swear to that. It was ported by Ed @ 4+6 in Chicago. His ports never looked anything special but they flowed well.
Maybe he measured differently?

No....at 10". Low #'s so low??? Are you retarded with valve size? What size was that intake valve were you flowing in that 240cc head?? It is a K750 head. If I stuck a Harley valve in there I'd get great #'s too. :teazer said:
I flowed another today with less work.. .100 26CFM .200 49CFM .300 69CFM .400 79CFM .500 83CFM. Jesus Christ.... that is better than Branch or Larry Cavanagh ever had.But ...wait....I am SURE Berreth was better though you have no knowledge, or sheets/records or...or......or...........or anything to back that up. ??? ??? :
Your opinion. :I could tell you were a guy with a chip on his shoulder...no offense again...I'll show you in real time with video and sound what is working if you want.
Bring it on brother.... F2/F3/F4i to GS 1150 with big valves. Bring it.....I am not afraid.Let's see "Ed's" #'s" on a CB750. I'd like to see his bench too.
An aside....I'm always interested in seeing other peoples total crap valve actuating systems for the bench as well as their inability to show real CFM as they flow.
Jeez...those #'s look a bit low compared to my Hayabusa lift #'s :teazer said:
: ??? An old thread revived because of your basic disrespect, ignorance and half ass attempt at being social (maybe 10" is different in Wisconsin than MA....really?......you chooch) Next....I'll post pics of my CB750 billet block. I am sure you have developed something far superior for small block Honda vintage racing (though I have thought of it using Nikasil like my 750 cylinders). Difference is I could make it happen.
Another interesting sideline I noticed...I was the 94th member of this site....you are 5019th....not that makes a difference but those who come late to party always bring the most................................
That is an interesting questioning as the fella from Australia (who commissioned the LSR head) said they where the best figures he had ever seen for a stock port early CB750. He spent his life porting but is unable to continue secondary to age and overall hand wear. He is not a young man by any means. He choose me to port that upcoming LSR head after a world search of 2 years (tooting my own horn).teazer said:
He is the one that posted those flow figures and they were the best he has ever seen for a CB and he is old enough to know. He also said the low #'s were incredible (compared to his best)....that basically means you know absolutely nothing about CB750 flow #'s ( in regard to valve size etc) except what you pick up on the internet.
You should keep your mouth shut teazer if you do not know what you are talking about especially when you choose to criticize. I will give you this gentleman's email and you can ask him about porting etc.....he has forgotten more than you will ever know.
Christ teazer....you have a way of pissing people off....at least me with you and your know it all attitude and flippant remarks. I'd love to meet you face to face and have a real dialogue about motorcycle 4 stroke logistics....I am sure it would end in a positive light for both of us. And I truly mean that.
