brian r Posted March 16, 2005 Report Share Posted March 16, 2005 (edited) Good question, I've just been using 10 w 30 but I'd like to know the answer also. Edited March 16, 2005 by Brian R Quote Link to comment Share on other sites More sharing options...
vintagecota Posted March 17, 2005 Report Share Posted March 17, 2005 10-30 Castrol is what I use. Quote Link to comment Share on other sites More sharing options...
toofasttim Posted March 17, 2005 Report Share Posted March 17, 2005 That's sweet Brian. I know of one in a warehouse here. Quote Link to comment Share on other sites More sharing options...
bwc352 Posted May 15, 2005 Report Share Posted May 15, 2005 The xerox copy that I've seen of the apparent manual for the 200 indicates that it takes 600cc (or 20.25 oz.) of 10w30. Quote Link to comment Share on other sites More sharing options...
vintagecota Posted May 15, 2005 Report Share Posted May 15, 2005 (edited) The factory later revised the clutch/gearbox capacity of the 74/123/172/200 engine to 900cc. Edited May 15, 2005 by vintageCota Quote Link to comment Share on other sites More sharing options...
bwc352 Posted May 16, 2005 Report Share Posted May 16, 2005 VintageCota, So, that means that I should be putting in 900cc instead of 600cc? That seems like a HUGE change. Do you know what prompted them to revise the suggested amount of oil? Thanks. Quote Link to comment Share on other sites More sharing options...
vintagecota Posted May 16, 2005 Report Share Posted May 16, 2005 Not sure why, but I'm trusting an ex-Montesa mechanic who has copies of all the service bulletins for that info. Quote Link to comment Share on other sites More sharing options...
bwc352 Posted May 16, 2005 Report Share Posted May 16, 2005 Thanks VintageCota. I'll be sure to increase the oil to 900cc. BTW, I really enjoyed another posting of yours where you gave your ratings of the various Montesas of that era. Thanks. Quote Link to comment Share on other sites More sharing options...
bwc352 Posted May 18, 2005 Report Share Posted May 18, 2005 The service advisory for the 200 that increased the recommended gearbox oil from 600cc to 900cc got me thinking. Was there a similar increase in the recommended oil for the 349 gearbox? My 349 manual says 300cc for the clutch and 300cc for the gearbox. Were these suggested amounts for the 349 later increased? Or are they still correct? Quote Link to comment Share on other sites More sharing options...
vintagecota Posted May 19, 2005 Report Share Posted May 19, 2005 Thanks for the kind words, but actually the manual calls for 300cc of 90wt in the gearbox and 200cc of 10W30 in the clutch. ATF is now recommended for the clutch. Quote Link to comment Share on other sites More sharing options...
brian r Posted May 19, 2005 Report Share Posted May 19, 2005 I can conferm that my manual says 900cc for the 200 Cota. Quote Link to comment Share on other sites More sharing options...
bwc352 Posted May 23, 2005 Report Share Posted May 23, 2005 Thanks VintageCota and Brian. For the 200, it was my first oil change (I just got the bike) and I added 900 (thanks to you guys). As for the 349, I double-checked my manual and it really did say 300 and 300 in my particular manual. Strange. Thanks for the feedback. The more information that I can gather, the better.

dgshannon Posted May 23, 2005 Report Share Posted May 23, 2005 OK, all these manual changes, additions, and updates have me wondering about the latest and greatest on my bike. What are the recommended fluid weights and volume for the gearbox and clutch on a 1974 Cota 247? Quote Link to comment Share on other sites More sharing options...
