hey guys, I have come into a little extra money and want to start gathering parts for the second build of my CB750F. I currently have it on the road. It was not rebuilt but it is running and ride able. I will be doing lots of frame and suspension upgrades and i know what i want to do for those... but the one thing that has me stumped on what to do is the motor..... I am hoping that you guys can help me plan my motor build.
I want to have a dead reliable modded motor that is increased in performance as much as possible without sacrificing reliability from the stocker and can handle some spirited riding in the back roads, a trip here and there to the local road course, and maybe a trip down the drag strip every now and then. but i need the motor to be as dead nuts reliable as possible. I will also probably use things in this motor that may not get used to their full potential but can be great conversation pieces. (possibly Mreicks billet heads, maybe the dry clutch that has turned up etc...)
so far these are the things that i have come up with for the build. I hope that you guys can fill in the spaces for me and confirm my thoughts on these things....
Motor is a 1978 CB750F motor. It is in a 1976 CB750F frame.
Gaskets - all honda genuine where applicable
cylinder head - not sure what is good for these motors so i am hoping that Mreick can chime in on this for me as i will most likely have him build the head. I want to get it to rev nice so lightening the valve train would be great. titanium retainers will most likely get used. don't know if they benefit from increasing valve sizes. and I'm sure that he has the porting and polishing down to a science. I am hoping the valve guide problem with this motor can be addressed as well.
Camshaft - don't really know what is available and reliable power makers in this section
rocker arms - i have heard M3 lightened rocker arms being mentioned.
cylinders - big bore kit... I am not sure what size is reliable in these motors. I am guessing that a 836 us rather reliable due to the amount of people using them. which brand is best? i see kits ranging from weisco to cycleX who makes the better pistons etc...?
cam chain - have heard good things about the tsubaki heavy duty cam chains.
cam chain tensioner - heard good things about the M3 cam chain tensioner.
rods - have heard Carrillo rods being thrown around as being good rods.
Crank - will probably have APE do their magic on it. how extensive should i go before you start getting into reliability and running problems?
cylinder head studs - APE heavy duty studs.
transmission - have heard back cutting gears being thrown around. are there any other modification that can be done to increase performance without hindering street ability?
primary chains - heavy duty primary chains. I think i have heard the M3 chains being thrown around the most.
Clutch - APE extra plate kit and heavy duty clutch springs
Oil cooler - i think terry (from OZ) has a good adapter plate?
I have built car and truck motors things ranging from ford 289, 400 (now a 408), modular motors, chevy 350s,454s. etc... but motorcycle motors are a new thing to me. I really am at a loss in which direction to go for these things as some things are made by multiple people but may not be the best in terms of reliability. so what do you guys say?
help a brother out???
Thanks in advance
Justin
