Pulse adrenaline 125 leak behind front sprocket help?

**Biker1234** · 09-26-2015, 03:57 PM

Hi, I've noticed lately that there's been an oil leak coming from somewhere on my pulse adrenaline ! Today I finally managed to get some time to trace where it's coming from and it seems to be from behind the front sprocket :( Does anyone know if this is an easy fix and just a case of taking the front sprocket off and fitting a new seal ?or is it going to require splitting the engine cases to fix it? Also if it's just a seal can someone point me in the direction of the one i need to repair the leak as nothing is coming up online . Thanks

You answered on your question - take off sprocket, pull out old oil seal, fit properly new one and problem solved.

That's good that I don't have to split the engine cases to resolve this issue! .Anyone know where I can get the seal from ? I've tried searching eBay for the sprocket seal even under Gs/Gn sprocket seal and doesn't seem to come up anything on eBay .

If I'm not mistaken, it is something like 30x40x5 or 30x40x7. Google that.

Thankfully seals and bearings are Engineering parts as opposed to Motorcycle parts. As Zorge pointed out there are 3 numbers.

Biggest number = outside dimension
Next number= inside dimension
Smallest number = thickness

Same for bearings

Even motorcycle companies have to buy bearings and seals.

Fag in this discussion is top of the line bearing as opposed to a guy wearing a suit and mincing around a wine bar.
