ok here we go.. so i found this bike that the guy said just take it, i said ok, it has set for years and the motor locked up, he has took and took parts off for his other 2 bikes and then he cut the frame to get the motor out which u dont have to i found that out when i picked up the new frame ,,,


ok on to the plan, i want to make a bike that me and my wife can take on long rides and be comfortable, the rebel is a great bike but not for long rides. i dont want it to be show room looking , i just want it to be fun, its going to take a while to build this and im thinking im going to need help and alot of little parts that i see im missing, but whats the fun of building a bike if its all there and also i will keep the balance of what i have in it on here so lets call this a budget build, lol.. well i know i wrote a lot so lets get started..


roller and motor and little bit of parts $free
the new frame $35





ok on to pics

here is the frames

so is one frame a hondamatic and the other something dif? what are you building? btw i just found a 750 frame in my shed haha. anyway, thats a good start, will be much better to have a 750 to ride you and your girl on.

i have a 750 auto motor and a regular 750 frame, the motor fits , but i i do know im going to need a head, and maybe the jug,, valve cover, and shifter , but im have 3 rods on the shifter side and i know ones the shifter but i dont know the other 2 and i need to find out if anyother 750 parts will fit this motor or is it just the 750a parts,,,,,,,

here is my list so far for what i need , but being a budget build i have to go slow on geting parts


cylinder head
jug
valve cover
engine gasket set
coils
igntion
tires
shifter
kickstart
front brake caliper and hardware
rear brake arm and hardware
wireing , ill try to do myself.
battery, long way till i need this
chain and both sporkets
exhaust
throttle grip and cable and coke cables
nuts bolts engine bolts and bracket

i think thats it , i may add more as i go

[tango911]

i have a jug, cylinder head, and valve cover from a 77 CB 750 You would prob need to Hone the cylinder and re ring, and measure pistons and cylinder to see if they are both stock.

I have coils i think, a shifter, kickstarter lever, front brake caliper, might have sprokets, i have engine bolts and brackets.

Are you sure the Auto engine fits in the regular K frame?

i found some info on the 750a

The CB750A used the same engine as the CB750, but detuned with lower 7.7:1 compression and smaller carburetors producing a lower output, 47.0 hp (35.0 kW). The same oil was used for both the engine and transmission, and the engine was changed to a wet sump instead of dry sump type. A lockout safety device prevented the transmission from moving out of neutral if the side stand was down. There was no tachometer but the instruments did include a fuel gauge and gear indicator. For 1977 the gearing was revised, and the exhaust changed to a four into two with a silencer on either side. Due to slow sales the model was discontinued in 1978,[18] though Honda did later introduce smaller Hondamatic motorcycles (namely the CB400A, CM400A, and CM450A).

sounds like it might work then if you want an automatic. i have two extra 750 engines, non auto, if your in need of one. i had one running already, has a small oil leak but if your going to put the kit in it, you just tear it down and re gasket anyway. the other engine is from an actual 1977 cb750K it turns over and has compression. im sure it runs but havent seen it yet. im swapping engines on my 72 right now i might throw that engine in just to see if it runs well.

hit me with an email and ill send you my number. you can come over sometime and check out the parts.

[tango911]

fyi on the 750's, you have to remove the oil pan, the oil pump, and the oil filter to get the engine in and out of the frame.

Also theres a tab on the bottom right front mount hole that you can grind down to help the engine fit in smoother.

[tango911]

no prob, just make sure you check everything before you start her up. valves, points, timing, carbs, etc..........
