Project Red Headed Step Child ruh roh damage!
« on: June 03, 2010, 06:03:44 pm »
well last year i got my endorsement so i sold my dirt bike and went in search of a street bike. the only thing i found that fit my budget was a 1978 CB750K i found i craigs list. it had mostly everything. was missing a mirror and that was about it. it puked gas when you turned the petcock on but that didnt stop me. i started by taking the airbox off and that took care of the puking gas problem but didnt fix it. it only worked because the excess gas was getting sucked into the motor. finally i bought float bowl gaskets and took the bowls off. figured out the floats were way off reset them and went on from there. riding in the summer i could never get the bike past 75 period. it had lots of oomph but died right at 75. figured out i had a leaking head gasket and the rings were bad on one piston. so this past winter i took it apart and got a little carried away and here i stand now ready to document putting it back together finally. no pictures yet but i will get some up of the carbs.

a list of what im doing/done:
replace rings* and head gasket*
paint frame*
paint tree*
bondo* and repaint tank*
new fork seals*
switch to superbike bars*
new brake bleederoem one was wrong using the original for now.
paint random parts*
fix rotting seat pan (glass and go baby)*
recover seat*
rebuild carbs*, paint carbs*, cuss a lot while reracking carbs*
new points*
double spring points*
switch to podsreinstall air box*
buy new headlight bucket*(dont use aircraft stripper on your headlight bucket)
new gauge faces* (p/o put a f model tach on it so it was really off)
cuss at gauges while putting back together*
replace idiot light cover* (broke tabs off by accident)
drool over the thought of a 850 kit.(not going to happen right now)
shoot guns instead of working on the bike at the lake house*
drink a lot of beer*
repair right side cover coming up with another option
find a left side cover (flew off on the e-way)

If it's not a 650 it's not really the redheaded stepchild. ;)

Excellent!!! I'm working on the same bike!  What kind of paint did you use on the frame!?...It looks like a wicked finish in the picture.   I'll be watching this one!
Cheers!  And keep the goods coming!

i got one problem i need help on. i cant seem to get the top tree clamp back on the stem. i remember it coming off pretty easy, too much paint in there? should i sand it out. i dont want to wedge it on with a screwdriver or anything. im tired of painting.

Instead of sanding you my try getting a *very* small paintbrush and using some aircraft stripper on the inside of it where the stem slides through. Either that or get a stiff scraper to spread the sides apart a little bit.

Looks Slick man! I didn't know they had flat enamel! COOOL

About your top tree not sliding on....myself, I'd do a little finger sanding until it wasn't too tight?...maybe wrap it around a lil' pipe or broom handle and do circles.....  but the stripper sounds good too!  I'd just be careful with it.

CHEERS! and thanks!  Love the build!!!

sand the paint off the area that slips on to the stem. dont use stripper!!!! it will bubble the paint beyond the area you applied it to.

You really don't have to sand between each coat.  If you go with 3 thick coats of clear, and bake it on....you can wet sand/cut the paint with 1500 grit wet paper and buff it out.  The paint will have the wet look....and it will show off any bodywork that wasn't done perfectly.  The key to nice body work is in the work done under the paint.  a GOOD paint job will show all the flaws....especially a dark color.

Then I suggest a light color, since the bodywork won't be perfect.  White?  Silver?

Well, then if you wnat it to actually look good, and are going to paint it black....then you need to get real about getting things perfectly straight.  Any little dents sticking up need to be tapped down and filled...and the whole tank block sanded....then primed...add a black tack coat, and block some more....any areas with black paint still on them are areas that need to be addressed, and you do that until it is MINT.

Your call....but if you don't, and you paint it black, it will look like $hit, IMHO.

no....not as much........I didn't mean to be rude in my last post.....but BLACK is the Hardest paint to get bodywork to look good.  Black shows everything....it's a bodywork magnifying glass.

The bodywork I'm talking about isn't hard......just takes some time with a sanding block.

ive been a little lax on the pics but i got the front suspension back together with the rear swingarm back on and most of the front end put together. tank is coming along. it will be a 5-10 foot looker wasnt looking for perfection, just something better than what the stock tank looked like before i fixed her up. put super bike bars on upside down, thought they looked better that way, will have to get seat done so i can do final adjustment of those and see if they hit the tank that way. if they do ill flip them up like normal bars but i like how they look this way i have a crappy cell phone pic il throw up. didnt have the good camera with me today.

edit here are the pics

handle bars
