    With my 4RT awaiting disassembly to repair it's cracked frame, I took the 314 to the HPTA event in Lake Mackenzie, Texas this weekend. The bottom-end knock is still there, but my buddy and League team member K-Rad talked me into competing on it. Oh why not, right? Besides the aforementioned engine knock, the fork seals are hemorrhaging, the front brake pads are soaked in ancient fork fluid, the rear shock is blown, the front tire is the original Michelin and is chunking apart, it carburates terribly, and there is no kill switch. What could possibly go wrong? :lol3

    I decided to ride in the Amateur class, mainly worried about finishing on the old gal. Not many pics of it (too busy competing and taking pics of my riding partners). Here it is after completing (and cleaning!!) it's first competition section in well over 10 years -

    At the end of the day not only did it finish, but managed to win as well! Glamor shot, with a very tired me behind it. Man, this is a heavy bike!! :knary

    I got the usual catcalls of "Sandbagger!" and "Move him up!" at the awards ceremony. The 2nd place winner (an NMTA member and a friend) good-naturely grumbled about me riding that class so I offered him to go out and re-ride 3 sections, him on the 314 and me on his new 250 Beta and we would compare scores. He turned me down for some reason. :lol3

    The search is on for the parts to overhaul the bottom end. I'm pretty proud of the old gal, so phase 2 of the restoration will commence! :D

    The 315R needs a 42 instead of 40 rear sprocket, but the only one available is in UK. I thought the hub was AJP and got a Talon T210-42 six-hole sprocket for a Sherco. The 315R uses a smaller Talon T232 and that's UK with ? shipping and eBay saying "this item may not post to USA."

    Anyone got a decent 42 in the dust bin? Brutus?

    Putted around in the garage today on the 315r. It's got a decent knock going. After reading a bit online I'm worried I've got piston slap and need a top end rebuild. Sounds like finding a new piston and rings may be literally impossible. Dennis at overland said he doesn't have them and can't get em. Splat shop in the UK looks to have the pistons but no rings. Any one else have a suggestion?

    Danggggg I guess the scarcity of the parts allows them to charge a premium. $400 US for a piston and rings is pretty pricey. Albea has them at quite a steal for $200. Everyone telling me to get a montesa when I was searching failed to mention difficulty in finding some of these basic parts :/

    Now you will have a $1,230 bike that has a fresh engine and clutch! Winning.

    Try some good quality fuel. 100+ Octane Race Gas will do. The 315's are famous for knocking with low grade fuel.

    You're in the 314 thread.

    I had nearly forgotten this. I rode my old crank-knocking 314R all season long last year with the High Plains Trials Association in the Amateur class. I was convinced that the engine would let go anytime, but the old gal held together. :D I can't imagine that there are many other 314s in competition these days, and riding it last year just made me smile at wrangling it's heft around the sections.

    Year-end champ!

    I received a very special gift this past weekend from the family that originally owned my old 314R -

    I hate to drop in on this old thread, but you did name it "the 314r thread".

    I've spent too much of the last couple days looking up parts info for the 314r. There's a bike I can get nearby for cheap. The motor and rear suspension seem good... can never be sure, but it seems that way. The bike seems like it is relatively low hours, and never been raced at the top levels. But the front left fork is leaking, which has contaminated the front brake... which could explain why the current owner thinks it climbs well, but doesn't do so well downhill :) I've found a parts list (in spanish), and spent some time puzzling over it. None of the part #s are of much help as no-one seems to stock/sell them. If it was my bike already, I'd just rip the forks apart, clean what I could, measure what needed to be replaced, and go from there. But as cheap as this bike is, I really don't want to buy it and then just turn around and part it out as un-repairable. There were references to sherco's using the same paioli forks, but that doesn't seem to be the case, the sherco's don't seem to have used USD forks until _way_ later. The 315 apparently used a 38mm paioli, where I believe the 314r is 36mm ... certainly the 315 and 314 parts lists are not the same, similar, but not the same.

    Is it a dead horse? Any tips on alternate sources for fork seals?

    I ordered fork seals for mine from Mike at the Tryals Shop last winter -

    314s are big heavy Water Buffaloes. Clean 'em up, make 'em work, and any 1997 & newer (and even some Air Cooled Monoshocks for that matter) Trialer will run circles around it. Just sayin'.... :D

    awesome. Thank you.

    They gotta be lighter and quicker than the TY250R I just looked at (my other option). And it's not like I plan to race it, I just want to sharpen my enduro skills by learnings some of the trials techniques... and even in the enduro world I'm on a pig of a bike (DRZ-400).

    Since the rear shock gave up on Miss Bitters' 315R yesterday, I decided to drag the old 314R out of it's cubbyhole to run the coyote today. I wasn't too worried about blowing the shock or the fork seals since they all leak like sieves anyway. :lol3 Spiked the old buffalo with some fresh Sunoco/Motul mix, and I'll be damned if it didn't fire on the 3rd kick. It hadn't run in well over a year. :thumb

    6 laps on a big Water Buffalo with zero suspension damping sure wears a guy out.... :knary

    Has it been a year almost already? Huh. Dug this relic up out of it's cubbyhole, fired it up and ran it around the pit a while. Now if there were only an event coming up soon to take this buffalo to..... :hmmmmm
