Okay. With reference to this post we are only getting to this now in all seriousness. We bought the bike for next to nothing and can spend a few moolas to build something good out of it. We did not expect much taking into consideration the price we paid for it.
https://wilddog.net.za/forum/index.php?topic=57058.0
Firstly the bike starts and smokes so an engine rebuild seems on the cards. Seems that the CDI is caput, moertoe as being the reason why the engine don’t want to rev. The bike have no lights, loom for the lights, indicators, horn, switches, etc. so lots of stuff to get together.
DOOM PICTURE but nice challenge. :thumleft:
We acquired a nice workshop manual with lots of additional info from the Yanks. Seeing that there is no loom or any electrics on the bike it seems like a donor Yamaha SR250 will be the answer, preferably one with a running engine. The bikes share a lot of parts end even lots of engine components. Ultimately the engine can be fitted into the XT250 frame as well, which we want to try.
Quote from the CD: (Only if we don't find a donor SR250 engine) :deal:
“If your ignition side is Not working.
You will need a donor bike the SR250 is favourite.
Remove from your bike:- Battery, Loom, Ignition Coil, CDI, Rectifier, Over Voltage Limiter, all Bulbs, Rotor and Stator plate from engine ‘ Note you will lose oil use a drip tray.’ a Rotor removal tool helps its the same part number as a DT125.
Strip all these parts from your SR250 after confirming they all work.
Then you would need to replace the stator plate and the rotor, the rectifier the CDI and the coil, both handlebar switches, all the bulbs and the battery to give you 12 V.
You will have to make up plates to hold the CDI, the Coil and the rectifier.
Note: on the SR the 12 volt power is switched to the CDI via the right hand switch via the red and white wire, this is why you need to change the switch over. You can still use your original coil if you wish, but you would need to mount it on an insulating glass fibre plate.
Kick over the bike and you should get a really healthy spark, start the bike up and confirm the 12v battery has 12.8 v to 13.2 volts with the engine revving.
I have now done this conversion to 2 bikes with complete success.”
FINDING THAT SPARE PART.
My local Yamaha dealer has not failed me yet, every part I ask for he can find the part number and place it on order, it always turns up within 5 to 10 days, not bad for a bike that went out of production 22 years ago.
This is partly due to the fact that the SR250 which shares a lot of common parts with the XT250 has had a very long production run, from 1980 until 2004.
Other similar bikes that can supply parts that may fit or can be made to fit with a little work.
Part Will Fit straight in Will require work to fit Worth Considering
Speedo and tacho XT125 DT125/175/250 XT350, XT600
Head lamp DT125/175
Head lamp Brackets None DT125R
Loom None DT125LC not R SR250
Switches DT125/175 & DT125R
Rear Wheel SR250 ‘but 16 inches’
XT350 DT125/175
KX125/175 Kawasaki Kawasaki KLR250
Front wheel DT125/175/250
Exhaust Header Micron. CRD, BSM, Predator Kawasaki KLR250
Exhaust silencer Micron. CRD, BSM, Predator
Rear Axle SR250
Brake shoes SR250
Seat XT600E 1992 on
A further bonus will be electric start together with a 12V system as apposed to the 6V currently utilised in the XT. There are other possibilities such as adding the kick-starter to the SR engine as back-up, adding the SR’s centre stand, loom, instrument cluster, switches, indicators, big round headlight, etc. Remember, this is a project, so no limitations. 8)
So the search is on for a well priced SR250 in running condition. We were already too late for one which sold for R4 000 in good running condition and now looking for another one to break up.
Any inputs form anyone who know something about the pros and cons of such a project please feel free to give advice of throw in a 2c worth of comments in order to help us build this XT250 into a close as possible perfect small DS bike, suitable for a young lady who wants to ride short to medium trips. :ricky:
