If you have a new Fiddle II 125 and you still haven't changed out the factory lubricants, you need to change them out a.s.a.p. They should have been drained-out and replaced somewhere pretty close to 300 kilometers (around 186 miles), which is according to the Fiddle's owner's manual (see periodical maintenance schedule, pg. 23).
For first time engine oil replacement, use a good brand of 10W-30 conventional motor oil. For the first time transmission oil replacement, maybe use a conventional or semi-synthetic SAE 85W-140 gear lube.
Once you reach around a 1000 miles, I would suggest the switch-over to synthetics in both applications. Amsoil 4-stroke Synthetic Scooter Oil is touted as the best engine oil for your machine.
There should be a speedometer drive cable that runs from the instrument cluster to the front wheel of the bike.
- Make sure the cable is connected both at the instrument cluster, and at the speedometer drive gear on the front axle, between the wheel and the fork.
- Ensure the drive cable is not broken - this may not be apparent by simply looking at the outside of the sheath. You may need to remove the cable and ensure that there are no breaks inside the sheath.
- Ensure that the speedometer drive gear is not worn or broken. This will require removing the front tire and disassembling the speedometer drive gear box.
- If all the above items check out, the problem is likely in the instrument cluster, and will require repairing or replacing the instrument cluster.
Hi. I would only use a good motorbike chain lube for your motorbike as a bicycle chain oil may well be to thin and will increase chain ware. As for oil, check in your service book or manual. If you do not have one ask at you local motorbike shop and they will tell you whitch oil you nead. Regards Tony.
The honda xr125 and honda cg125 have the same engine. I have changed the oil several times on my xr125 and I can confirm that you follow the same procedure for both bikes. There is also an oil change demo on youtube for the cg125:
