83 430 Rider Project

I am more impressed every few days when I get on this thread and see your work.
Keep it up

I really hope you folks don't get offended by my picture documentation. I learned a great deal from the guys over on Yamahaenduro.com about documenting builds. Pics are worth a thousand words. Every little thing you do to a bike can help someone out. It may just be mounting a spring in the right place but if you have never done it.............at least you can see the way it goes together.

Thanks outdoorsman. I am just a home hobbyist. I like to build "stuff".

Some more updates..........Yesterday I worked on a whole bunch of other stuff. I had to make a bunch of shock eye parts, and after that I worked on the brake stay arm. The mounting holes were wallowed out real bad. I looked at the parts fiche and there should be a bushing in both ends. Of course this bike didn't have them. I had some stainless rod in my stash and made a couple to press into the arm once I bored the holes back to round.

I had already blasted the rear brake arm and painted it. I cleaned up the rest of the little parts...........to get the white paint off. Ready for install.



Put some electrical tubing over the wiring and isolated the kill switch wire so there is no doubt to where it plugs in.


More tomorrow. This build should be coming to a stand still soon. I have to order parts.

No problem on the pictures. A picture saves a thousand words I like to say

This is one thing I like to do after installing zip ties and cutting them off. I take a soldering iron and melt the sharp protruding end flat. I learned this after working on off road race cars and watching a guy cut his arm open reaching down into the rear of the car. My safety tip of the day.



I was looking around at the pipe mounting stuff that came with the bike and stuff was missing. I remembered that there was some kind of spring set up on the upper mount. The parts fiche confirmed that. I went out and looked on one of my other frames and found most of it. This will help immensely.



Greased and mounted up the rear brake pedal.

There wasn't much on the TV last night that was interesting so I decided to work on the levers. Here's a sample..



I took off all the white paint and black paint underneath this one lever and got it down to bare aluminum. I had a real fresh clutch lever in my stash that I didn't have to do much with it. This is after the black paint was taken off. Pretty rough casting.



I had a couple, 3, or maybe more adult beverages in me and decided to take a file to the lever. It smoothed it out some what. I then took an emory board and some fine sand paper and then the polishing wheel to it. Made quite a difference and will look good enough on the bike.



All mounted up on the bars.

Top mount 430/500 if it's any help

Thats a better one. Mounts of the top tube , I used home made rubber washers. Still working.

Thanks for the pics Wildebeest. For some reason in my feeble little brain, the spring thingy to me seems kinda lame. But then again I drink beer so maybe it is not. I have thought about a rubber isolating grommet to separate it. I do like your pic showing the clutch cable routing. That is one of my next things to accomplish.

I spent today going over to my buddy Brian's and going through a semi trailer of stuff that came from the Curnutt factory. I will post pics if you all want me to. It is historic stuff. It brought me back to when I was a young lad.

Thanks for the safety tip! I'll be using that one.

Hmm, talking of drinking beer, I went to a funeral yesterday. The exhaust pics post was a complete surprise to me when I looked this morning

NO MORE PUI FOR YOU!! Even though I liked the pics.

I've been having all sorts of fun mounting the tank. The stock damper is hard and won't give much. Trying to slide the thing on has busted my fingers a couple times. It was really starting to irritate me. So I pitched it. I had some of this foam stuff laying around and cut it down to this.



It was still a little thick so I tried trimming it with a razor knife. That wasn't working out so well. Hmmmmmmmmmmmm wonder if the wire wheel on the bench grinder would work. Being real careful..........it worked. The tank went on much easier and still had padding.

Continuing on with day 15 of the gubment lock down I finally got the tank on and the pipe mounted. I picked up a silencer yesterday at my buddies scrap yard in his secret treasure trove. It will fit with some mods. I had to cut the inlet down about 3 inches but still have plenty of tubing to mount it. I remembered I had some rubber tubing laying around to mate the pipe and silencer.


I made a couple of bushings for spacing it away from the frame while still retaining the stock width of the mount.









More to come maybe tomorrow.

Looking good.

The first part of this week I did get a couple of things done before they called us back to work. The pipe was hitting the plug cap no matter how I tried to mount it, so I pulled the pipe off and figured out the easy way to get the pipe in and out. I got my plumbing torch out and heated up the pipe and put a small round dent in it for clearance.



I finally figure out how I was going to do the upper mount. I tried it with a bolt and the spring deal and it was too much of a hassle to try and get the pipe where I wanted it. It may be just me but it just wouldn't work no matter what I tried. I ended up using a shorter bolt and putting a thick rubber washer in between the metal.



Of course while I was doing all of the moving the pipe around and taking it on and off the rear rubber mount separated. I just happened to have a few in stock from other bikes I have parted out. I always keep little stuff like this around. It is a little smaller diameter but the thickness is correct.

I worked on the silencer and cleaned it up a little and did a trial fit. It is gonna work.

I was surfing on one of the MX forums I read daily and this pops up with a link to ebay. One of my old race bikes I sold about 15 years ago. I built this purposely for the unlimited class for the CZ World Championships. Me and my buddies often wondered what happened to it. It was in a collection in Utah at one time. It's kinda a husky kinda sorta.

Here's the link
