A literal barn find at the base of a ski resort. Dry stored in a relatively arid climate. Left home at 6am, drove all day with the dog, grabbed the bike for $400 CDN, drove straight home and was last vehicle on the last ferry home. It languished on my bench for a while as I sourced some silly...

I know 120/90 is the max on a rear 2.15 18 rim. So dropping down to a 70 should work no?

So I'm almost done my restoration. I'm converting it do dual front calipers. I have two brake line distribution blocks that are Yamaha but I can't seem to get the angles right. I want a collector plate on it, but the rules say I can upgrade brakes if period correct and factory option. So the...

Bought a GoPro in the winter and tried making some video last night. I didn't get some of the shifting edits right but it came out ok. Looking forward to trying some better editing software. 10 minute ride video around Vancouver Island. https://youtu.be/TxkXMTmjda0

I searched for this and maybe didn't use the right term. We've always called them service tanks. A tank on a pole that you roll, clamp or affix to run the bike without the giant main tank. There are a few on here that are pretty handy and a few that want to have some inspiration. I guess I'm...

My old yamaha two-fiddy has a 2 wire single phase alternator into a reg/rec with a ground and TWO power wires coming out. I'd like to upgrade to the three phase mosfet, they usually have a 3 phase input that can be used with a single phase stator. Although derated a bit. Anyone had a problem...

I'm using a kerchief wrap but it's not optimal. I have it folded in on itself a bit and covering my face, but I compromise neck coverage that way. I don't want to wear the kerchiefs. lol I've thought about a cheap pair of yoga pants from wal-mart and cutting the leg off as a tube. But I...

Here in Canada, insurance is cheap up until 400cc. At 401cc, you jump nearly triple in cost just for basic. Just to park it on the street. No coverage for theft, fire or collision etc. I pay about 15 pounds a month right now to insure my 250 with basic. If I had a 400cc bike, it would be very...

Yep, heading home from work in the dark last night and it was 8c on the way to work today. Heated vest, getting reacquainted with the choke, idle air screw half a turn out. Goggles away and bubble visor out. Motorcycling in Canada at its finest! Mind you, I'm not sweating my balls off anymore...

So I put a monster cam in my 250 thumper. The old one was worn to a nub. The carb has a 155 air jet and a 130 main jet. With the 130 it bogs on the top end-3/4-4/4 throttle and hesitates a bit at 1/8 throttle, just after letting the clutch out. I tried a 140 air jet, no change. 135 jet and it...

It seems like the majority of Yamaha rocker arms share the same part number family with different model number idents between singles. Example: 583-12151-00-00 29U-12151-00-00 The SR500 appears to have an oil hole on the slider. All angles, lengths and castings appear the same except for...

I've had a lot of helmets in my day. From bmx, to sportbikes to enduros etc. etc. The d-ring is a tried and true system sure, but I bought a cheeseball Zox helmet on a whim last year for passengers and tried it out one day. The quick release on this $40 helmet was fantastic. I hate fiddling...

Ok I got my 3 foot long pipe capped on both ends with silica. One end has a bolt and a lathe turned pressure plate. The sand is compact. I heated it until it glowed and tried reefing on it in the vise with the jig I made. I moved maybe 2°. Stumped. Now either I need to gain 100 pounds or I...

From what I can tell, it's a 74 750 super sport. Apparently it's the underside that is the key.

I'm looking to ditch the mags of course. Swapping to a rear drum is easy. So is keeping the disc with a front hub. I have a lathe, large truing stand and a millng machine so making something reasonable fit can be done. But where to start if I can't locate a decent rear Yamaha hub? Any dirt...

Any of you swapped to a dry sump engine and used the frame as the oil tank? The motor I'm looking at holds just over 2000cc of oil and I think I could connect a sealed off top tube to the motor. Is keeping the oil away from the fuel tank the best bet? And the replies that say "just buy an oil...

I'm tempted to part this out but it's a complete bike with even the side covers. It's the perfect cafe candidate since you're gonna rip all the rusty stuff off anyway. No papers, has a key. Good compression but no spark. I'm just not in love with it like I am the XS360 I got. It needs a home...

I've got an XS360/XS400 starter that screeches when the bike stops running. I think. It also screeches when I kick it with the kick start. Something is dry or worn. Anyone know what noise I'm talking about? The starter clutch might just be bone dry?

Signals, seat parts, tank, clutch lever, etc. What have you got?

So I wheeled the 360 into the shop from storage today. I wanted to tackle some of the basics with it to see if it's worth doing up. Turn the key and nothing. Switch checks out. Continuity until I get to the rectifier. Now, I'm colour blind so me and wiring diagrams is a spectator sport. I...
