I actually pulled the forks off last nite to added 10W.
I poured them out first and measured how much oil was in each and both were at exactly 250cc's. Put the same amount back in.

I didn't measure my used fork oil. However, I can testify my forks work much better with 330 ml of Mobil1 Synthetic ATF in each fork.

Have you noticed any difference since doing it. I have now had chance to test mine and it feels much the same, perhaps a slight improvement. |

But there maybe a few who wish to do a fork service etc. and maintain the original factory setup after a fork oil change. I'm starting to wonder if this is possible with 330cc of oil no matter what the grade. |

I didn't decide on 330 ml of for oil, myself. I merely followed the specification listed in the CSC maintenance tutorial for fork service.
http://www.cscmotorcycles.com/Articles.asp?ID=263 I also know from seven years of experience studying, and working with Chinese motorcycles, that the forks are almost invariably low on oil as configured at the factory. However, I do understand if someone wants to keep the same amount of fork oil as received from the factory. Everyone is free to configure his motorcycle exactly as he wishes.

Is this a necessary step if all you are going to do is swap the oil?? |

A lot of oil is stored in the cartridge. If you want to get the oil out of the cartridge, yes, this step is necessary.

I'm sorry to bear the bad news, but I'm betting there is a lot of oil in the cartridges. Even if you don't get 330 cc of oil when you empty the cartridges, I still suggest you follow the CSC specification.

Thanks for the feedback! We pulled the forks back off today and after removeing the spring and pumping the internal shaft many times and pouring the old oil repeatedly I was able to get much more oil out of the forks.
Just about 330 cc's The frontend feels much firmer and less dive when braking.

You're welcome.
You experience corroborates mine. I knew the forks would perform much better with 330 cc of heavier fork oil.

Just a question reviving an old post.... would changing the stock oil be a bad idea for me, as I weigh 165, but occasionally ride 2up. Also, would the Mobil 1 ATF or the lighter Valvoline ATF be better? Lastly, after reading this thread and tutorial, would I remove the spring and pump the forks until 330ml comes out, or it's empty? If i don't get 330ml's out, I would just replace with the amount removed.
Ive not done fork oil before. Thanks all! |
