Yammie 400

[bradleymaynar]

For those that don't know, I was given an '80 Yamaha XS400. Unfortunately the air filter boxes are missing so I was considering going to pods. What kind of issues can I expect, if any, if I do this? The exhaust is stock.

Thanks

You can expect lots of issues trying to get the bike to run right. I say this from experience having owned an XS400 before and trying pods. The only way I was able to get the bike to run right was to use the rubber velocity stacks that connect the carbs to the air box and clamp the pod to that. The rubber extension worked great to smooth out the air entering the carbs thus allowing them to run right.

Hi,
Nice little bike.. if I were you ( and not in a hurry ) I would ckeck for an air filter box on eBay. If you go the air pods route, remember that these carbs were tuned for the EPA era and most likely hard to tune. I can only speak for 1980 Yam XS650 but people have had many problems with cheap air pods bought on eBay, the easiest to tune were unipods, from Uni-filter ( the foam type). Take a look at http://www.mikesxs.com/tech_tips.html they describe what you'll have to do on these carbs to make them work . Mikesxs is also a good place to buy new parts for yammies ( mainly for XS650 but many parts were interchangeable with teh 400 )

Hope this helps..

Thanks for the link. I've still got the tube that connected the carbs to the filters. My biggest problem is that there appears that there were boxes that the filters went into. Those, and the side covers, are missing. I'll have to check again, but I believe that Bike Bandit showed those boxes as being unavailable. I can still get the filters, though. It just seemed that they'd be a bit more exposed than a set of pods (and I was looking at the Uni's).

Make adaptors and clamp the pod filters to the rubber extension tube. Worked for me.

That's the bugger!:-D Pods it'll be then.

Thanks for the ebay link, Sylvain. I think I saw that yesterday, too.
