Hi from Brisbane, Australia. I am recently retired from work and looking for something to occupy my time, I purchased a 1994 SRV250 with 63,000 km in need of some TLC.

It had not been on the road since 2010 and had quite a few issues, front brakes seized, seized throttle cables, tank dents, taken a hit around the headlight area with bent headlight shell and instrument brackets, leaking fork seals, surface rust everywhere and previous home to some critters (mice, mud wasps and spiders).

Tore it down back to the frame, cleaned, painted and have replaced quite a few parts.  Professionally, I have had the tank repainted, forks re chromed and the headstem lockstop repaired with the frame checked for straightness.  The motor is untouched except for new plugs, valves clearances checked, lube service and carburetor jets, gaskets, o-rings & diaphragm membranes replaced.

After almost 2 years I have just put it back on the road, been for a few short rides and loving it. 

I came across the forum a while back while searching for info on the SRV. It has been very helpful, especially for part substitution, so thank you.

Hey everyone - 

I've just got my first bike, a[attachment=163] 1994 SRV250 - she's a beauty!

Ok question number 1:
I noticed the dipstick on the oil cap is missing.. can this be replaced with a standard 2-stroke engine cap or something like that? Can't find anything online and it didn't come with a service (or any other kind of) manual..

Also what type of engine oil do we put in these bikes?
SAE 20W-40? I live in a place that gets really cold in winter and really hot in summer..

Question number 2:
I bought the bike with the choke disconnected and removed Sad
Can't find any aftermarket choke mechanisms online for this particular bike.. Is there an alternative choke that could be used for the SRV250? Like maybe one from a Virago or something??

Any advice appreciated, ta!

From 9pm Sept. 22nd to about noon on the 23rd, the forum was offline due to a power outage caused by typhoon #17.


I kind of doubt anybody noticed, but do apologize for the inconvenience.  Hopefully it was the last one of the season.

Found a great example of a wheel/brake upgrade.  Check out this link for the original.

This is a quick translation of the original post:

Yamaha R1-Z Front end:
wheel, axle, forks, disc, caliber, fender, meter gear

Apparently it's just plug and play except for the front master cylinder, which needs to be swapped for a dual caliber model.

Yamaha R1-Z Rear wheel, disc, caliber, chain adjuster
Yamaha Zeal caliber support
Suzuki GSX-R750 Rear caliber master cylinder
SRX400 1JL Swing arm (Same as SRV but the axle is 17mm so you need to use the R1-Z chain adjusters which are the same15mm as the wheel.)
He doesn't remember if he used the SRV250 or the SRX400 pivot shaft, though they are the same size.  The width of the front of the swing arm is different so he's got 3 washers on each side of it. The end plates are listed as for the SRX400.
SRV250 Axle shaft (The R1-Z axle shaft is too short.)
Use 2 washers (spacers) on either side to make up for the difference in width.
SRV250 rear brake switch (With some modifications)

SRX250 Rear Step
Apparently the pitch didn't match up so he modified it. (See pictures) This mod moves the step back about 2cm.

The swing arm is longer so you'll need to change your chain.  520-120 link should do it.  Since the mount points of the rear suspension have moved forward, you need to make some adjustments against interference with the rear step. (Again, without actually doing the mod, I'm not quite sure what he's talking about.)

Hi All,

I have just purchased a 1994 Yamaha SRV in Sydney and looking forward into giving it a little TLC. Currently the fuel tank is off and being restored, giving me time to give it a deep clean, adjust the carby, reset valve clearances etc.
Seems this forum might be a little quiet at the moment but it would be great if it were to pick up again!

Okay, this wasn't on my SRV, but I still wanted to post a ride report showing my favorite two hours of twisties.

Last day of my vacation and I finally managed to force some time for myself to join in the Japanese tradition of "The First add anything here of the year."  I got my first run in and it has been a couple of months. (My bike let me know by the battery just being strong enough to turn it over.)

The weather was cloudy and cold (about 10C) but the roads were dry as it was sunny yesterday.  Here's a link to my favorite stress release:  Nagasaki Twisties

This route will take you up behind the town of Omura in Nagasaki for anywhere from an hour and 30 minutes to 2 hours of riding.  It goes by 3 different dams and stays in the mountains for almost the entire time.  There are only a few places where the roads are narrow enough to be considered one-lane (by Japanese standards.)

I had a great ride and definitely didn't feel any cobwebs.  Concentrated on good lines through the corners and felt I was able to up my average cornering speed.

When I got back I topped off my tank with Hi-octane and then washed and waxed the bike.  The weather is gonna start getting cold now, so I probably won't be riding for a while.

Now if I can just motivate myself to get my SRV back up and running!!!!

Hey Guys,

Recently I cleaned out my bike shack and went through my parts box.  There were a number of parts I probably won't be using and I thought I'd post them here to see if anybody could use them.  If you are interested in anything shown here, post a comment and I'll post more information and/or pictures.

Since there is a 5 attachment limit on each post, I will post the pics in replies below.

Clicking on a picture will show a larger version.

Here's a nice looking Green SRV250 from Australia which I pulled from the Facebook group.  Would be nice to see some more pics of this lovely looking bike.
