All 2st Who has the sano seat fix? The Dr Suess pin just aint cutting it...

I'll check the front of the seat, that sort of rings a bell there. I wish my wr wasn't 200 miles away, it would make things easier. Home remodeling ... fun stuff...

Grease it. Dzus fasteners are great. Most commercial airliners have engine cowlings, etc., held in place with them at 600mph and they hold just fine.

How about a picture.....

If you've lost the plastic washer for the Zeus clip (which is why it will loosen up), you can make one up by trial and error using plastic lids. Alternatively, you can twist thin safety wire from the seatbase hole to the D-clip...won't stop it from coming loose but will save you from losing the bolt.

Take the pin out of the seat and try it in the receptacle. If it locks OK, then look at all the points of contact between the base of your seat and the bike. It sounds like your seat is sitting too high and not allowing the pin to protrude into the receptacle enough to lock properly. If you find the seat is sitting high or the receptacle is sitting low, do something to change it. Ie. bend the subframe tabs, remove staples from base of seat etc etc etc...

Just like ohmygewd had said about the plastic washer. The next step is to install a piece of rubber hose around the front mounting post. Remove the post and find a piece of thin wall rubber hose and cut to fit around the post underneath the washer top( don't know how to describe that front mount). It will make the front tighten up and maybe help keep the seat on. I added an additional washer to the dzuz fastener and did the front modification because I felt my seat move around too much.

So I decided to replace the whole shebang. Sick of having my seat fall off on every ride. Got the parts in and decided to try the new pin before I drilled out the pin seat. Viola! Click! The new pin clicked right into the locked parallel position and life is great again. My original pin had to be defective somehow because it never would close no matter how hard I pushed or cranked.

It's a simple thing but not having to worry about my seat was a relief. Also, not having to explain to my waiting riding partners why I'm bringing up the rear with my falling off seat issues.

Now I need to figure out a steering damper for my 12' wr300...

What size and where did you get the replacement Duez pin? I have a spare seat I want to set up.

i just received a new dzus and its washer from halls...

they sell the complete unit on ebay for $12

Glad you got it sorted...my seat seems super solid on both bikes...the tool less access sure beats bolts IMO

I recently fixed a mates WR250 who had lost 2 dzus clips and found that he had snapped one of the seat hook/lug..anyway, M10 countersunk allen head, drill through the rear guard, a wingnut and spring washer is the only way l could fix his problem at the same time of making it semi tool less.

Got the whole shebang from Hall's. Only needed the Seat pin.
