cb450 build/entry : part 1

Brad sent me some pics and a little background on the start of his build for the ozark mountain scramble. couldn't be more stoked to have others start to make a commitment to the run, let alone as much help Brad has been willing to shell out. here's the skinny from the horse's mouth...

The first picture is the 72 CB450 as I purchased it. A 24K mile unmolested original. I am lucky because I get to be the first to molest it! The bike looks a lot nicer in the picture than it really is. Underneath the seat, tins and tank it is very crusty.The second picture is after I spent a few hours stripping it down this morning. The 3rd pic is the parts that will go back on the bike in one form or another. The last picture is of all the parts that I am going to try to sell to fund the build. I was careful with the wiring harness hoping to sell it as a complete, unmodified original harness. I got a crash bar and luggage rack with the bike that will hopefully be able to bring in a few bucks. I spent $900 to buy this bike. My thinking is that spending extra for a very good engine/trans etc would reward me because I can do most of the rest of this build with rattle cans, elbow grease and scrap metal. I paid $20 for the black 1/4 fairing in the third picture so I am at $920 on a $1000 budget. I am hoping to sell most of the take off parts and maybe pump another $100 back into the budget so I'd have $180 for paint, chain & misc - maybe a new front tire. Of course there will be things I didn't plan for so I need some extra $$.
I really like the CBs that Dime City Cycles is pumping out so I am doing a mild "Manx" style early Cafe build with this Honda.

kz400 build/entry : part 8.5

this post isn't really much of an update, but i figure it can't hurt to post what's going on at the moment. to summarize in short, absolutely nothing has been done to the bike for a multitude of reasons. mainly due to laziness, crappy weather, thin wallet disease, and my all time favorite four wheel transportation kicking up random fits wasting what little garage time i have available. however i am proud to finally say that an 8oz can of POR-15 tank sealer will be in route today. this will coat both the intake and gas tank giving me the first opportunity to hear it's hearty vroom vroom noises. exited to say the least.

kz400 build/entry : part 8

time in the garage has been extremely sparse. recently i got a nice bit of motivation to get things rolling steady again and decided to get some sort of plan in action. my goal recently has been to finish one or more tasks on the check list each time i am in the garage. luckily i have been doing 2-3 per session now, which has been dramatically reducing the length of said list.

points gap, valve adjustment, cam chain tension, and timing advance check have all been accomplished. everything was pretty close to spec, so it is good to know it probably had a tune up before being cast away. due to low funds i have yet to order the POR15 to line the tank and intake, so finishing fabrication in other areas has been moved to higher priority.

fender mounts are now tacked into place and pretty much ready to finish weld. i also drilled the hole for the tail light mount, so that wraps up most of the rear. i then started working on the seat pan mounts when my welder ran out of wire, so that will have to wait till i pick up a new spool. in the meantime i trimmed the top triple tree a considerable amount to get rid of unwanted mounting tabs.

i also got a chance to address the exhaust issue i have had. whoever installed the aftermarket mufflers must have been rushed or lacked the patience necessary for proper fitment. the chain side pipe was super tight to the swingarm and chain, but just enough clearance. however, the brake side was no where near identical in placement with an extremely long bracket that threw symmetry out the window. i decided to mimic the chain side and get them both tucked in as tight as possible. no picture of the bracket, but it's not exactly anything special really anyways. since doing all of this, both mufflers and clamps appear to be sealing properly and super rigid. i took some time with the wire wheel to clean them up as much as possible, and was surprised how much nicer they looked. nothing fancy, but they will do until i can snatch up a set of new megaphones for replacement.

this weekend i would like to get the seat pan finished/mounted, make a headlight mount, front brake stay, and get the tank mounts finished.


seat pan: the bracket sitting on top in the first pic will be welded to the bottom of the pan for strength(second pic). probably way overkill, but it's ready to weld on.





fender mounts: super simple, but nice and rigid. i'm not a huge fan of the squarish narrow fender right now, but money is tight . when i get some extra scratch i'll try and get a rounder profile one to work with.





tail light: mounted and now i have to decide how i want to do the tag mount.



intake: a few more pics of it after blending some welds.







top triple tree: trimmed.



petcock: the position is making a simple tank mount a wee bit difficult.

kz400 build/entry : part 7


i've been on hiatus from the garage for quite some time now. back in the saddle, i have made some progress. seat loop can be checked off the list now. i whipped up a seat pan as well, but still need to make the mounts and sort out the foam.

ozark mountain scramble



i'm going to bump this post every few months to keep the buzz going. i'm hoping to get a pre-run in soon to start working out any possible kinks.

it's official. there are still some loose ends to tie up, but the general route and date has been determined. lodging currently is the only questionable item at the moment, but rest assured it will come to fruition. with the date set for June of next year, you have plenty of time to get a work horse assembled and your calenders cleared for three days. i'll try and update whenever new information comes to light. any and all other information will be mainly kept here----------------------------------->CLICK

feel free to spread the word around.

kz400 build/entry : part 6


i've been slowly plugging along on the kz. unfortunately i haven't had much time available to me in the garage, so i am doing what little i can here and there. on my lunch break, i snatched up some rectifiers to build a new one. the old setup was haggard and unfit for road use by any measure, so it was time to finally build one from scratch. there are quite a few different setups i have seen built before, and all are supposed to work just as good if not better than the stock setup. total cost from radio shack came in under $15 versus the usual $50-$100 used units on ebay. i have a chunk of 3/8" aluminum stock to be used as a heat sink, so that is covered already. i received my new petcock in friday leaving only a few things left on the list to check before the first start.

1. check valve timing
2. points gap
3. check advance unit/weights and clean/lube
4. make gaskets for new intake
5. simple wire job to run

kz400 build/entry : part 5

i finished the intake fabrication, which means i will finally get to hear it run for the first time. nothing beats that accomplishment other than the maiden voyage itself.







Craig at Front St. Cycle bent up some tubing to get started on the seat rails. yhe plan is to start this weekend on it, but i would rather not take focus off of getting the bastard running right now.

kz400 build/entry : part 4

got some more work done on the intake over the weekend. unfortunately my angle grinder brushes are toast leaving me fumbling to finish. not much left but the snout that attaches to the carb, so i am pretty stoked on the progress.



also snapped a couple pics of the tank mounts.

kz400 build/entry : part 3


single carb intake in process. i'm in the tacking phase without enough hands, so until i can get my buddy over to be my "holder" it will have to just wait. no pics of it, but i did get the tank mounts tacked into place with only the threaded bungs left to attach to the frame. i hope to have the intake finished and the bike fired up by the end of October leaving me all of November and December to finish tuning and any fab work.

i'll be tossing the starter once i get it tuned to a one kicker.
