carburetors

My xs400... Running, AND FINALLY ROAD WORTHY! So I bought an '82 Yamaha Maxim from some guy locally. It looked like Barney. :( I got it and it ran pretty smooth, freshly cleaned carb (looks ultrasonic clean when I opened it up :thumbsup:) and re-jetted. The only problems were a worn back...

Drop yer cocks & grab yer socks!. . . . .and run out an get one of these gizmos right away! 200 bucks for me after I got ass-raped outta 50 bucks on shipping ($150 for most of you south of 60). I picked up a dirt cheap '73 CB750 this spring that has been in a shed since '96. The bike has...

So I put my bike back together yesterday after replacing the battery, draining the tank, changing the oil and filter, cleaning the carbs and putting some cleaner in the fuel. I tried to start it up and no luck although it was a cold day so i was not too bothered. So today, I tried again and...

So I recently did a carb dip and ever since the butterfly valves seem to close slowly when not connected to the bike. I have not hooked the carbs back up to the bike as I found one of my diaphrams does not push smoothly, kinda makes a thud when pushing. Is there anyway to grease the butterflys...

Hey guys. Since I haven't got a vacuum petcock, I just plugged the vent-hole on the boots with a rubber-thingy. When I was out for a ride(pretty long I might add), it came off. I didn't notice until I came to a stop and the bike didn't respond as usual, kept high rpms for a while and then...

Hi ,I've been looking for a good source for carb kits for my '82 xs400rj seca.Everywhere I look,they offer some parts,but I want to rebuild them right.There was a post with a kit,but the site was in the U.K.,and I'm in Hillbilly country[$$$ for shipping].If somebody can put me onto a good...

I am looking for some insight because I am, yet again, about to give up on tuning this bike. I can rev through the entire range of rpms, but she tends to hang at 3,000, and slowly fall to 2,000. Sometimes she falls down to 1,500, but rarely or never back to idle at 1,000 to 1,200 on her own. If...

Hi all! I'm in the middle of cleaning my carbs, and think my jets are 'backwards'... The manual says: L/H 127.5 R/H 117.5 BUT, looking at them (air filter side up), it's 117.5 on the left and 127.5 on the right. I assume left and right should refer to the rider's left and...

Well a set of carbs off an 80 xs400 fit on a 78?

Can the two carbs on my bike share an air filter without causing problems? I am thinking of building a 2 into 1 air filter tube connected to a larger filter beside the engine rather than 2 filter pods. I don't want to move the carbs, just the air filter.

Well first off this is my time to this site and I hope y'all could help me on a few issues. I have a 1981 XS400 and it runs great other than sometimes when after coming to a stop after doing some riding, it tends to idle high sometimes and at times it doesn't. I'm trying to figure out why is it...
