i had just had my rear suspension re-built, re-valved and new spring put on my '03 from factory connection over in quebec. i used to work in a bike shop here in pemberton bc, and we were always sending f/c our rebuild work, but down their shop in cali. always with good feed back and great service. so i thought this time i would keep it in canada and send my unit to f/c’s new shop here in quebec. i spent $500 in labor, oils and parts and then $50 each way for shipping. $600 (ouch!). i had a lot of other work done to the bike as well, and was not able to get riding until may long weekend. may 18th i think!?! 8 - 10 rides and i'm loving it. the rear end is perfect right out of f/c's box. no bottoming and smooth as butter. i'm 220lbs, and i felt 180 again! with the combo of the re-build, re-valve and new spring f/c hit the nail on the head. the $600 was well spent. but...... june 21st, 10 small local rides, only few hours each, and less the 20hrs on my completely rebuilt bike; from front shocks, new bearings all the way around, all new top end with new valves, springs,piston, rings, yz exhaust, chain, everything. all done by myself. thousands spent on parts, and all the time over the winter dreaming about one day having everything put back together and riding again (everyone here knows what i'm talking about, or should i say; dreaming about), and what do i see - a oil puddle under my bike. ahhhhhhhh. no big deal right! everything was running great. maybe it is a loose engine bolt, or gasket, easy repair right! nope. my new rear end has the leak. the only thing I didn’t do myself and the only thing I thought would not fail me. from factory, the rear-end has never leaked before, and if there was a problem on the inside of shock, f/c probably would have caught it. right! no? anyways - long story short, 20hrs new suspension, leaking, now off the bike and in the mail back to quebec (other side of country), at least 2weeks rtn. f/c says they will replace anything at their cost if they find it was their mistake, and cover the shipping. the down time is the worst thing to live with right now, and the possibility that this rear-end is going to cost me more than $600. i am not rich, and far from it. i always try and buy performance parts that will work for me, and not scared to spend for quality. but will this leak again? anyone else with a f/c suspension? anyone with a leaked rear-end? why would mine leak? thinking of buying a spare from ebay. will a '03 yz fit a wr? part numbers are different but i think they may be the same in size and probably could fit my '03 wr. pls, comments welcome!
