Has anyone changed the clutch on a Stallion 150cc engine? I'm working my way through a cafe racer 150cc bike and have now got it running great but it really needs the clutch disks and possibly the basket replaced. Not taken it apart yet.

 

I have had a look online and found references to it being a Chinese clone of a yamaha ybr engine albeit with bigger piston / bore to make it 150cc. Nothing concrete though which is where you guys might be able to help me.

 

Actual engine on the bike is numbered JS150.

 

Ideally I'm after confirmation that it is a yamaha ybr clone or some other clone and i can substitute the clutch parts / case gasket using yamaha parts which i can easily order online. And also find the workshop manual detailing valve clearances etc to check my work. Unless any of you legends already have a workshop manual for a stallion 150cc cafe.

 

Thanks

Maybe he can help.

One would think any Stallion dealer. But OP didn't tell us where?

I'm in Phuket and we have a dealer in the town, 88 motorbike and whilst very friendly they aren't keen on supplying me just the parts. They want to fit them - understandable for the mechanics, but i love playing with bikes.

 

It is also a struggle explaining what part i want without workshop manual / parts manual to point at unless i disassemble the bugger and bring it in - i'm succumbing to the fact that that is what will need to happen.

 

For what it's worth i'm certain that this engine is not a clone of a Yamaha YBR engine or the Jianshe JS150 engine due to oil filter placement.

 

 

For bits for my 250 Stallions, I usually contact the spares dept. at the factory via LINE - the only contact on my LINE account! If you can photograph and highlight the bit you want, with a description, and send it off, they're quick to get back to you. Delivery a couple of days after payment.

 

If you have Facebook, send an enquiry about things like valve clearances to https://www.facebook.com/stallionsmotor/  and they'll reply. Used my wife's account for that. Can respond to English but Thai is preferable, of course.

There should be another engine code other than JS150. Maybe something like 156 FML. Check near the oil drain plug. Your engine seems to be based on the Suzuki GS 125. Many of these "type" of engines are based on either Suzuki or Yamaha.  Valve clearances ; (OHV - IN = 0.06 mm. EX = 0.08 mm).  (OHC - IN = 0.08 mm. EX = 0.10 mm). These are good base figures. Set on compression stroke.  These engines run hot , use 10/50 or 15/50 oil. The carbs dont like too much ethanol , so use E10 rather than E20.
