Those tank seat units were sold by Sammy Miller products. They were very good until Ethanol was added to petrol,completely wrecked mine. a shame because it was signed by Mick Andrews.
Sorta what I thought. This one had been coated with.....something, and the coating is starting to dry and crack. I've heard a bit of muratic acid will re soften the goop and get it to coat again. Don't know if I will do that or just get an alloy tank/shelter assembly and be done with it. This one sure looks nice, though...
Ethanol isn't a problem with my bikes, I run Avgas in them so the problem shouldn't return if I decide to run that tank.
I'm also on board with a still dirty carb. Replacing the pilot jet does nothing if the pilot jet passage is blocked, resulting in a running condition like you are describing. Completely disassemble the carb, dunk it for over an hour in real carb cleaner (or get it sonic cleaned), rinse, blow out ALL passages with spray carb cleaner and compressed air. Reassemble and enjoy!
315Rs are notorious for "cold sticking". The Calvin Klein-priced Elf oil helps, but the best fix I ever ran across was replacing the solid steels with dimpled ones. Also makes the clutch action more progressive.
When I saw Brewtus found one, I had to grab this 305! Rode it around the yard today and it's going to be an awesome bike!!! She needs some love, as a former owner thrashed it around pretty hard. I have some grand plans for her...
Nice Robbie! Pulled-back bars and dropped levers say it was beat on by a go-fast guy. Looking forward to seeing what you do to that scoot.
It's probably not worth going to an OKO unless you're changing the air box and exhaust BTW, the original carbs are very good at what they were designed for
If the slide isn't completely worn out, that is. Not an uncommon problem out here in the wild, wild west, but YMMV.
Fairly rare here in the States. One of our Mountain West Vintage Trials club members has one, but doesn't compete on it much anymore due to fears over parts scarcity. Where is it located, and what kind of shape is it in?
Glad to see that waif of a Fantic in good hands. I had put the ad up over on ADVs Trials forum, that's how I recognized it. If it weren't so far away, I'd buy the 2 YSR50s that the seller had also.
Link to the ADV post, look halfway down the page -
No sir, I don't own a WB Fantic. That one was for sale up in your neck of the woods, just wanted to know if you were the one that snapped it up. Can't tell by the blurry pics, but it does appear to have a cable clutch.
you could try reaching out to these guys at Mid Atlantic vintage trials.They have been selling and setting up OKO carbs on all sorts of different bikes for quite a while and might be able to help you out.
If you left the petcock open for any period of time (especially if you transported it), I'll 3rd Line's diagnosis. It is a pain, but the petcock gets turned off on my 315 anytime it's transported or stored between events. For that matter, the petcock gets turned off on all of my carburated motorcycles for transport and storage. I really don't enjoy fuel-filled engines.
Remove the fuel tank, remove the spark plug, kill switch activated to prevent current getting to the coil, kick until premix stops blowing out of the spark plug hole (may want to lay a towel over the hole to prevent premix from covering you and the bike). When little to no more premix comes out during kicking, wipe off all the premix you can find ,replace plug and tank, point the exhaust towards and open area (or something you don't like such as the neighbor's cat), and start it up. Run it until she's nice, hot, and clear. Shut off the petcock during storage and transport, cuss at it when turning it back on, ride and have fun!
Awesome pics and mods, Wobbler. I really dig your old Warhorse! I'm starting peg mods on mine this week (hopefully) in between finishing up a couple of customer bikes and taking delivery of a couple of new additions to the collection.
