paullyd9f3 Posted April 14, 2016 Share Posted April 14, 2016 Hi all, ive been riding an 86 fj1200 for about a year now and late last summer i noticed a slight drag on the clutch when i first start the bike. (first gear with the lever all the way in and it pulls away and or stalls) I rebuilt the leaking master cylinder a few months back with great results and fluid is topped off. is this a common issue with this era FJ or is there an issue i need to deal with? thanks Paul Link to comment Share on other sites More sharing options...
slice Posted April 14, 2016 Share Posted April 14, 2016 Hi Paul, welcome to the YOC, just so I know did you change the clutch line and did you check the slave cylinder which has a known problem as well? On my FJ I found that the slave cylinder was the real culprit, the bore wears and you get a back flow. Easy to do but can I suggest that you check out the FJ owners club site or this http://www.fjcatalogue.com/catalog/item/7221205/7432061.htm It is a cheap fix if you have clutch drag, measure the bore on your slave cylinder as well just to see if it's in tolerance. On mine I eventually replaced the fibre clutch plates as well just to be sure, try looking at this as well http://yamaha-parts.victordrummond.net/causes-of-a-slipping-clutch this guy has it all down pat, I followed his instructions and found that an upgrade he suggested was brilliant as you didn't get that usual FJ clunk when changing into first. that lot should keep you busy for a while mate. This is the full article on a clutch UPGRADE on an FJ 1100/1200, well worth a read. http://yamaha-parts.victordrummond.net/fj1100-fj1200-xjr1200-xjr1300-tutorials/clutch-improvement-and-upgrades PS can I suggest as well that you pop over to the New members section and say hello, just so folks know your not a one hit wonder, thanks. Oh Yeah and a photo of the bike if you would, we like photos! 2 Link to comment Share on other sites More sharing options...

DutchFJ1200 Posted April 19, 2016 Share Posted April 19, 2016 Hey Slice, Thanks for the above intel. Guess what ...... yup clutch going a bit 'spongy' on me yesterday. Immediately ordered master & slave kits :-) Strange how this occurs from one day to another. Friday I wouldn't have thought twice about my clutch operation ...... yesterday it was shiet !! As for bleeding the system, this is pretty straight forward with the master filled to the brim and gravity does the rest through the open bleed nipple at the bottom. Cherio !! 1 Link to comment Share on other sites More sharing options...
slice Posted April 19, 2016 Share Posted April 19, 2016 Hi Dutch, glad someone got to use the info, seems the original guy is a OHW, oh well ! Perhaps he will come back you never know. Just as an aside, I have a full set of fibre plates for the FJ, they are the original ones from my bike, all are the full thickness and can be used again, if your interested in them PM me and I will gladly let you have them.

DutchFJ1200 Posted April 19, 2016 Share Posted April 19, 2016 Yo Slice, Yup twas interesting reading. Thanks for the offer of the plates. Can you hang on to them for a bit. I assume that having to open up the block to deal with the innards is only a matter of time & mileage :-) I have 66K on the clock now so dunno when they will give up the ghost. Mind you that would be something for the specialist spanners anyway, I'm way to chicken for that. Also in addition to my lube oil thread the bloke had an interesting take on the matter : Motorcycle wet clutches are designed to run *only* certain types of oil... While synthetics are generally okay, any engine oils that contain silicon or other friction modifiers *may* cause the clutch to slip. Whilst "Yamalube" has a stupid name, I always run only Yamaha engine oil or a general duty diesel type motor oil in my own engines as diesel oils have a higher detergent content that assists to keep the clutch plates cleaner and the pores of the plates un-clogged. Sun's out !! 1 Link to comment Share on other sites More sharing options...
slice Posted April 19, 2016 Share Posted April 19, 2016 Yeah no prob I will leave them in the garage till you need them, again Yamalube is a stupid price and no better than a good quality oil. As for Diesel oil I'll try it right after you mate Link to comment Share on other sites More sharing options...
DutchFJ1200 Posted April 22, 2016 Share Posted April 22, 2016 Operation clutch tomorrow, Master & Slave refurb with all my newly acquired bits from Wemoto Oh and I just noticed that green box with '....vehicles' in the user box on the left. Updated mine with pics of every Yam I ever had. Not much compared with some of the retards on here I must admit Link to comment Share on other sites More sharing options...
slice Posted April 22, 2016 Share Posted April 22, 2016 Easy job Dutch, should only take a couple of hours and then your a speck in the distance! Link to comment Share on other sites More sharing options...
DutchFJ1200 Posted April 23, 2016 Share Posted April 23, 2016 Mission accomplished !!!! + lubricate chain & full polish. Speck in the distance ...... Yup. Erm ... oh yeah ... was a bit too enthusiastic spannering and split the bottom part of the clamp holding the master cylinder onto the handle bar. Anybody got one ? 1 Link to comment Share on other sites More sharing options...
jimmy Posted April 23, 2016 Share Posted April 23, 2016 Well done Dutch and Slice for rescuing this from another ignorant fucker 1 Link to comment Share on other sites More sharing options...
DutchFJ1200 Posted April 24, 2016 Share Posted April 24, 2016 My pleasure Jim And to turn this thing into a bit of a 'howto' : http://www.bikers1.com/load4.php Goto technical articles - 4th one down and that tells you all about the slave. The master is pretty straight forward as long as you put the new bits in the same way they came out - note : an internal circlip plier is a pre-requisite. ... how do I know that ... lol Link to comment Share on other sites More sharing options...
