Front Sprocket????

[Bigfellabuck]

Hi All, just checking the front sprocket on my bike and all seems to be well. There is a dotpunch mark on the gear shaft which tells me its been off to do the mod but how will I know??? How deep is the new nut compared to the old one? And the lock tab has been bent over in two positions telling me that thats extra security after a fix.




Thanks guys  Buck
