Yamaha XSR 700

I found my dream bike

Be green...

recycling old parts for other uses is much better than trying fill up the land fill. But it was my fultile attempts at reusing the HKS filter, that I destroyed at a past track event, I decided to use the filter elements for other uses. Yes it's still good in my book.

Odd goods

Tissue by Yamaha? Got this from a AE92 front clip at the shop. Don't know what it says, but I assume it's some sort of promotional item.

Scooter work

It's been some time since I've actually worked on my scooter. But I seem to have a renewed fondness for the scooter. Since I was actually prepping it as a pit bike for All Star Bash, I wanted to make sure it's running o.k. Being it's 25+ years old I'm sure I have to replace a whole bunch of stuff. But i'm not going to just need to get it going. Swung by the the Scooter Shop in Orange, Ca. Replaced these things called roller weights. For easy reference it's right across the street from Motorsport Auto, the Z gurus. Luckily these guys knew what I had and was able to find something for me.


The rollers were sitting on the shelves for so long that it has long lost it's packaging, this is how I got the parts. There seems to be different weights available. Lighter weights improves acceleration at the loss of top speed and heavier weights does the opposite. I've upgraded from 7.0 weights to 4.7, for better acceleration, hopefully it won't degrade the top speed much.


Never really tore apart the drive train on these things, but it's so easy I could do this stuff with my eyes closed and one hand tied behind my back.


Here's what the old rollers look like, it's flat spotted which is a no no. Acceleration gets erratic as the scooter gets up to speed.

This is the clutch assembly, looks like shoes for drum brakes. The clutch itself seemed questionable also. The shoes and clutch bell are glazed which didn't look good at all.


Some sand paper to rough up the surface should do the trick.


While I was at it, might as well change the oil. Yes the Rotella even finds it's way to the scooter.

Results: It definitely has a noticeable pep in the acceleration department. I don't know if my top speed has improved since I didn't have a working speedo. But who cares it's a definitely improvement from $13.00 parts

Go Riva Go!

I've got the scooter up and running. It even starts on the first try, or least it on the second for sure.


Bought a new battery for cause the other one didn't hold a charge when I attempted to charge it.

Tearing apart and cleaning the carb. No I didn't do it on the dirty concrete floor. I made sure I swept the floor. Even though the carburetor was small, cleaning all the passages was a tedious task. But it's not uncommon for crap to clog passages and jets. It's probably the reason for the hard start problems when cold.

We have life.

The brakes work o.k. at the moment, they probably need to be replaced soon. The wire harness has corrosion inside the terminals, which I could try and clean but would be a headache. Easiest would be to replace the whole harness. I probably won't be doing these things anytime soon, since I really need to get my car up and running.

I'd like to give thanks to Jeffery Street's website for having the information needed to help me figure all the issues. Cause I'm too cheap to buy a service manual.

Blue Thunder

I just picked up a Yamaha Riva CA50 scooter (Traded a pocket bike I won at the 4AG challenge). It's a dinky 50 cc scooter I'll be using as pit transportation. That's right I'm moving up, all I need now is a F350 Powerstroke dually and24ft enclosed and I'm set. It needs some work to get it up to running condition. But I'm having a difficult time finding good information online. Honda Sprees have more info than this scooter. So if anyone has any web links they can send me I'll definitely appreciate it.
