I think you need to decide what it is you want to build first.
Do you want to build a bike to its original design or build your own bike using the best bits from a variety of bikes? If you want to build an original bike get the workshop manual for that bike and read it.
A bike is just a frame, forks, swingarm, wheels, engine and electrics really, and then it's given controls and wrapped in cosmetics.

Re: Looking to build a CBR from the ground up

Honestly i would want the look of the honda cbr but then again for the motor i would want to build a better one and also build a better brake system. I heard building it from scratch is a lot more expensive and would take a lot of time but thats all i got.

You need to decide which CBR you want though, there are CBR's from 125cc right through to 1100cc starting from 1987.
If you want to build a bike from scratch using new parts it'll cost around three times the price of buying the bike _new_ - and a lot more if you have to get all the parts delivered to you. Using secondhand parts can still be more expensive than buying a complete bike.
The actual building of the bike doesn't take a lot of time once you have all the parts on hand. If you're using secondhand parts, then getting them and cleaning, inspecting and repairing them is what takes time.
I would suggest you work out the expected to costs beforehand to know it really is something you want to do. You're also going to need a fairly extensive collection of tools and room to work longterm.

If you have an engine that you want to build I would allow $1000 just for that, although you may come out of it cheaper. Rings, pistons, pins, clips, gaskets, seals, camchain, tensioner, crank shells and transmission bearings would take up much of that. Then add machine work like boring, valve cutting, crank grinding and such. Then add any replacement parts you might need like gears, oil pump, cams, etc. Since you mentioned building it "better" than original then you can add a lot more depending on how much "better" you want it. A set of nice cams could go as much as another $1000 for example.

And be aware that no matter how much you spend building it, even a perfect showroom-condition bike won't return what you've spent on it. For me, the pure enjoyment of building them though far outweighs the cost, and I never want to sell them anyway :-)

Re: Looking to build a CBR from the ground up

Yeai figured building it would cost a lot more but then again i love putting things together and if i actually build my own bike then i wouldnt plan on getting rid of it. I usually work and workout so building a bike would be perfect for my time.... You seem to know quite a bit about bikes which im glad you actually responded to my post. I dont wanna build a brand new one cuz i knew it would cost up the ass for parts but i do like the 07' or 08' cbr's and probably looking around the 600rr's and above. Not so much all the way up to the 1000's cuz i wanna work up to those ones. So im thinking i should build the motor second and get the body frame first. The cosmetics of the bike i can wait till the very end. I just need to figure out where are some good places to find 07 or 08 cbr frames and as for the engine im gonna pretty much start putting all the parts together as i get them. I wanted to ask how many different parts are part of the body, i was looking and saw that there was a frame and sub-frame, but what else would i also need???

The chassis consists of the main frame with engine mounts, footpegs and rearsets, rear brake pedal, gear shift and linkage, steering head bearings, lower fork clamp/stem, upper fork clamp, steering stem tension coolars and nut, forks, front axle and spacers, front wheel and bearings, front tyre,
front brake discs and bolts, front guard, front brake calipers with pads and bolts, front brake lines, clip-ons, throttle tube housing and cables, front brake master cylinder and lever, clutch lever and mount, swingarm with pivot bolt and bushes, chain buffer, shock absorber, upper shock mount/ride height adjuster, shock dogbone and linkages with bolts and bushes, rear axle and spacers, chain adjuster blocks, rear wheel and bearings, rear tyre, sprocket carrier with bearing and spacer, cushdrive rubbers, rear sprocket, rear brake disc and bolts, drive chain, chain guard, rear brake caliper hanger, rear brake caliper with pads and bolts, rear brake line and rear brake master cylinder.

The rear subframe just supports the seats, battery, pillion pegs, muffler hanger, rear lights, licence plate, battery tray and tail fairings.

The front subframe supports the headlight, instrument cluster, mirrors and front upper fairing.

The engine includes the radiator, fan and hoses, throttle bodies, airbox, exhaust system and starter motor. On the 600/1000RR the fuel tank fits into the main frame above the transmission. I can tell you that the engine itself consists of around 1000 parts :-)

The cosmetics include the front upper fairing, both side fairings, lower fairings, some infill covers, fuel tank cover, tail fairings, screen, headlight, both seats, tail lights, front and rear indicators and the mounting brackets and fasteners that attach it all to the bike.

The electrics include the main harness, front sub-harness, ECU, starter solenoid, several relays, fuse box, airbox sensors, battery, instrument cluster, ignition switch and right and left handlebar switch clusters.

Ebay is my only suggestion if you're determined to buy it in pieces. Generally you would start with a main frame, swingarm and engine from the same model of bike. Everything else can come from many other bikes or even be fabricated by yourself. If you wanted to use a different engine or swingarm though, you certainly can. You could use a 1000RR engine in a 600RR frame for example. Be aware that some bikes require the engine to assemble a "rolling chassis" as the swingarm does not attach to the main frame - the 929/954 for example.
