I am new to the TDub world and so far am loving the bike. I'm having a few issues (like last time I started it it idled fine, but any throttle input would kill the motor) but there are plenty of threads to resolve that (time for carb clean, maybe 130 jet, and fuel filter, you guys have posted TONs of information :) ). But there is one issue I can't find an answer to and I'm hoping for some help.

My bike didn't come with the seat bolts, and I've already lost the seat twice (stand up riding and a few mild off the ground experiences). I've searched the web and this forum and can't find anyone that has posted the exact stats of the bolts so I can pick them up at a hardware store today. I've got the yamaha part number for them, but even then the description is always "Yamaha Bolt" and doesn't give dimensions. Anybody know the size of those bolts (ex. M8 x 15 x 1, etc).

Thanks,

Todd

M6. But I wouldn't simply replace them. Then you'll have the opposite problem in that you'll have a heckuva time getting the seat OFF.

There are a couple of threads for ideas on homebrew quick-release seat bolts or pins you might want to look at.

Have a look at the inserts in your seat to make sure there isn't half of an old bolt stuck in there. A lot of times if the P.O. left the seat bolts loose they became sawn in half and the stub is still stuck inside the seat.

Welcome to the forum.

I've had to drag all manner of weird stuff into the hardware store over the years but I didn't think about dragging in the motorcycle seat. Good idea.

It ain't as if you'll need to unbolt it...

Yeah, read through the quick-release options, but I really don't see myself taking off my seat again until the battery dies, so wasn't too worried about engineering a quick release, just a simple bolt to hold the thing on for now. Even in those threads though I couldn't find the size. Modding will come shortly :)

So M6 bolt and a washer, I'm guessing an inch in length will work. Thought about bringing the seat in, but while I live in the city I leave the bike out in the country at my parents house, so closest HW store is 30 mins ride, and that's an hour that I could spend in the woods while I'm out there. I'd rather just pick it up on the way out.

Thanks for the answers.

i went with the joe band bolt method...it's def worth the extra time when you need to get at the battery or you want to add a luggage rack and need to take the seat off or you need to pull the tank off...you pretty much need to take the seat off for some maintenance things so it's worth doing...i would get a big fat zip tie and zip the seat down, ride to the hardware store and buy your bolts and spacers and try them while you're there so you get it right then you will be all set

my screw up...not long enough to spin the wing nut


this worked though...
