DT-1 air box #1
So I'm just doing some brainstorming here. Just got a 69 DT-1 this morning. Looking at it and it has no air box. And it seems they are obsolete. Any ideas for finding an airbox or making a different kind of intake? I'm totally new to the old yamahas and just checking into things before spending lots of money.

Thank you,
Ryan

While you are getting it running and searching for a OEM air box that could take months to locate. My suggestion would be to get a clamp on as a temporary alternative in the $20 - $25 range.

When you do locate the airbox you are going to need to trim the filter cage back, as well as get an air boot from KDI. By the time you're done it's going to get costly.

Kenny, post a picture of a KDI SEAT PAN, FOAM and COVER .. That air box may have cost more then the entire bike ...

agree ... Still its good to get an idea of the higher end prices so a more reasonable opportunity is not passed up ... I would go with a pod filter in the meanwhile and keep hunting .. Patience is essential . There was actually an airbox for sale here in Australia for a while and I was looking for it for this thread but it appears to have been sold.

Its a nice looking straight bike.. Tank, fork, rear guard all look in nice restorable condition...

Here is a more helpful link for restoration essentials that are more down to earth in price.. All their stuff is top notch...

I actually found one for a 70 DT-1 on eBay for 72 dollars. I think it had the same part number and such. A little bit of rust on it, but overall not bad! I bought it. I paid 150 bucks for the bike!

Great Job !

Honestly, I was thinking $500 if the engine was not locked up.

Carry on in Brave Fashion !

My plans are to do a lower end restoration and ride the machine off road. Clean and paint as much as I can to save on money and possibly do a motor rebuild eventually. Not sure what it will do at the moment, but I checked and it had spark and 130 psi compression when cold!
