2003 Yamaha Raptor 80 Restoration

Recommended Posts

Hi, All

I started this project a while ago.. I have decided to make one thread I can continuously update..

So , here we go. I got this Raptor 80 in really bad condition.. Rear end frozen, Engine toast, tires dry rotted, tons of rust..etc.. They admitted they beat on it very hard.

Since they do not make these with a drive shaft anymore I decided to restore it from top to bottom..

These are photos of when I got it home.

Next up, the tear down..

First, I needed to tear it down and determine if the rear end was still good... As we all know... That is where it would be cost prohibitive to restore if it is trashed..

Got it completely stripped down and I lucked out... The rear Drum brake was caked solid inside with dried mud. That was causing the rear end to lock up. Took off the rear brakes and the rear end spun perfectly smooth.

Once I got it all stripped apart I needed to take the finish off all the parts. I am going to be powder coating the frame and many parts.. Once the finish is off each part it will need to be sandblasted to white metal .. The guy I use for powder coating gives me a hefty discount if I bring the parts to him ready to go.

You could just sand blast, but that would take a long time to get the finish off. First I used Aircraft Paint Remover.. That stuff is pretty toxic Goggles and Resperator are required. That quickly gets you down to the metal... Then you can sand blast to white metal pretty quickly...

I had another thread I had started about a problem with the tear down... It has some great info .... here is the link... It is about removing the frame bushings. ....

This was another post i had made elsewhere:

Hi All,

Rebuilding a 2003 Yamaha Raptor 80.. Currently taking apart the rear diff. To get out the Pinion gear you need a Spanner Socket.. It looks like the part number for the Yamaha tool is no longer good.
Anybody know who sells the correct Spanner socket? Yamaha lists it as 32mm but I don't see how that is possible. Pin to Pin on the nut is 48mm.. Any help is greatly appreciated..

After no response I posted the following:

Ok, So it would appear that this question has been asked many times on many forums for many years and no one has ever answered this question... After many hours of searching I have found the correct information!

First pay no attention to the Yamaha part number in the Raptor 80 service manual, it is incorrect. The correct Yamaha Part number for the Ring Nut Wrench / Socket is YM-38404. But Yamaha no longer has this tool to ship. You have to order it directly from the company that makes it.. K&L Supply Company. The K&L part number is KL-0530R This number along with the Yamaha part number are on the tool itself. But when you call them they go by the part number 35-38404. That is the number you give them in order to buy the part. It cost $45 + Shipping. This tool will work on the rear end pinion gear and also on the rear axle hub. It is needed if you want to change worn out bearings. I am including pics of the rear pinion with the nut as well as the tool.
Here is a link to K&L

Well guess you don't get the link since I am new here... Go to klsupply.com and use part number 35-38404

Ok, getting out the Spanner nus in the rear end was a job, but the frame bushings were the worst... See the details in the links above.

Now the parts were ready for sandblasting and then to be dropped off at the Powder Coaters.

I am going with a Translucent Candy Apple Red Metallic.. First they lay down a chrome powder coating and then powder coat over that with the candy apple red.

Ok, parts are back...... These are all the parts I had done... The photo does not do the color justice. Outside in the sunlight it sparkles and looks like a candy apple.

First thing to do is to put in the new Frame Bushings.. I have a 20 ton press, but it would be pretty awkward to use for the bushings.. So, I made a bushing insert tool. It is 7/16" Threaded Rod, 3 - 7/16" Nuts 4 - 7/16" Regular Washers and 4 - extra thick 7/16" Fender Washers. The thicker and stronger the washers the better. I greased up the bushings and they went in with some wrenching. The last 1/8" was tough to get in, but the tool worked...

I got the front arm installed and I think I want to buy new shocks..

Can anyone recommend some shocks they have used and like?

Hi All,

I started stripping the engine down while I am waiting on some parts for the frame.  I ran into my first problem...   I cannot get the gear selector shaft out...   I took out the circlip.. Then the push lever behind the circlip is supposed to slide off, then you take a pin out of the shaft and then two washers and a ball bearing... The problem is the push lever seems to have fused itself to the gear selector shaft... I do see some rust.. I have spent the last 2 hours trying to take it off  and nothing has worked... gently prying, heating and tapping to  try and rock it back and forth...

Anyone have any ideas?... It is really on there...

Took me a long time to get out that shift lever. It was rusted solid... Kept spraying it with PB Blaster and worked on it evey hour or so in between other things I was working on. After a couple of days it finally broke free.

      Picked this beauty up for zero dollars this weekend. It has been passed around several of my son's friends and the last kid was just tired of tinkering with it.  Mostly complete 96 300FW. The pic is my boy robbing the swing arm and rear diff for his 300 for a big memorial weekend ride. Wiring is garbage at the battery, kick start doesnt work, no coil, smoked like cheech and chong when it ran last. I figure a couple hundred and a few hours and this will be ready to ride. Journey will be documented on Instagram at @martincyclellc if ya wanna follow along.

      I had a quad fall in my lap a couple weeks ago. The only things I knew about it was it was a Kawasaki Bayou 220, was in pretty rough shape and was free. I couldn't say no to a fun little project. I've been looking a different ATV forums gathering quite a bit of info and decided this was the one I wanted to join.
      Thanks to this forum, I found the VIN under about an inch of mud and cross referenced it to be a '98. It had been sitting outside for at least 5 years and was told it ran when parked, but had no brakes. Squirrels or mice had been chewing on the handlebar controls and it's generally just kind of beat up.
      So far, I've gone through the carb (not near as bad as I expected), freed up the brakes (will probably need new cables), replaced the spark plug, air filter, petcock and put a new battery in it.
      The gas tank had been empty and looked clean so I put some fresh gas in it and tried to crank it today. I got a neutral light, but the starter button did nothing. I tried pull-starting it and it wouldn't fire. I checked the plug and wasn't getting a spark. I started digging and found some potential issues and some definite problems.
      I have a wiring diagram I found on here but it's just a picture or scan out of a book and hard to read. I don't see a reference to a black/yellow wire, which is my first problem.
      First, it that a factory crimp? One of those wired looks like it goes to the connector in the 2nd pic. Is that just a spade lug type connector? I pulled on it with some needle nose pliers but it didn't seem to want to come off. In the 3rd pic, should there be a fourth wire?
      I've read through and bookmarked the threads Andrew Baker and Arizona have going but I figured I needed to start with these obvious issues first. I have lots of pictures, so if there is something else you want to see, just ask. If I don't already have a pic, I'll take one.

      I am hoping one of you knowledgable people can answer this for me. I have a yfm200 moto 4 engine I want to put in an off road go kart. I would like to mount a sproket where the drive exits the case before the u joint so that I can get rid of drive shaft and make engine bay compact. To do this I would mount engine 90° to axle but would also need to tilt it forward 15° to account for the angle the drive exists rear of casing. Would that be ok? Would oil pump etc still work. Any advice greatly recieved.
