Dr-ZnA Posted April 2, 2010 Hi all! I have recently bought a new to me KYB 48mm twin chamber supposedly off a 06 or 07 RMZ250. It had a seal leak and almost no oil in it.. Tried a search but couldnt find the answer.. Could anyone please tell me how much oil should be put in there? Quite urgent plz. Thanks Share this post Link to post Share on other sites
kawamaha Posted April 2, 2010 06 RMZ250: KYB oc fork approx 650cc each leg. you have to measure the oil level, which should be 100-90mm 07 RMZ250: Showa Twin chamber 380cc outer chamber approx 200cc inner chamber Share this post Link to post Share on other sites
scobes Posted April 2, 2010 48mm twin chamber kyb forks off a rmz..... think you have been miss informed Share this post Link to post Share on other sites
Dr-ZnA Posted April 2, 2010 I thought that i was misinformed too.. Been trying to find out what the forks are.. MX bikes are a very rare breed here.. So not much is known about it.. Share this post Link to post Share on other sites
scobes Posted April 2, 2010 Being 48mm theres a good chance they could be off a yamaha as they have had 48mm kyb for a few years now Share this post Link to post Share on other sites
Dr-ZnA Posted April 2, 2010 I bought it off ebay.. It was an RMZ 250 being parted.. Could it have been swapped? Share this post Link to post Share on other sites
kawamaha Posted April 2, 2010 what size wrench do you need to open the fork cap? 49mm? or 19mm? what is the diameter of the forks, 48mm or 47mm? Share this post Link to post Share on other sites
kawamaha Posted April 2, 2010 19mm and 48mm.. looks like a single chamber KYB, then RMZ250 2006 is right... Share this post Link to post Share on other sites
Dr-ZnA Posted April 2, 2010 Then how much oil? 650cc right? And do i need to bleed the air out? Which way would be the best? Thanks all! Share this post Link to post Share on other sites

Thanks all! first, visit this and look at the video https://thumpertalk.com/forum/showthread.php?p=9344409&highlight=#post9344409 then, you measure the level, not the volume 90-100mm Share this post Link to post Share on other sites
Dr-ZnA Posted April 2, 2010 Just watched it.. The problem is i dont have access to such tools here. As i said the MX stuff are very rare here. And if i order it from the US it will take 2 weeks to reach here. And i have a race this weekend.. Any way i could do it? Also what weight oil would you advise? Its for a lightweight 85cc supermoto..

mtdirtbag My Ride Posted April 2, 2010 Okay - you don't need anything special to put in the oil or measure it. I use a turkey baster with a piece of tubing; put a small zip tie on the tubing at the height that the oil should be from the top of the tube, place the tubing into the fork tube at the marked height and squeeze the turkey baster - it will pull out the excess and you should be at the correct height.
