Why are Yamaha's and Kawasaki's so frustrating? I've never had trouble wrapping my head around a Honda. Suzuki I won't comment on.
So the shop manual says that "88 and later" XV750's should have a carb fuel level of "2mm". The hell does this mean? 2mm above or below? Measuring from what point?
I've adjusted the floats to the maximum level and the fuel reads 7mm below the edge of the carb.
Can somebody please clear this up? The carbs are mounted on the bike and the bike is on the center stand. I've followed the manual's process. Here's what the floats look like now!
I don't know what series carbs I have. I can't find any 750 that shares this style.
Right, I've got a clear tube and I bleed the bubble out. I've done this before plenty of times.
These savages are playing one cruel trick. Look at how bent outta shape my float tang is and still the fuel is reaching no less than about 7mm below!
It's just like Yamaha to hop in and out of bed with whichever carb manufacturer happens to be giving it up on that particular night. Mikuni, Hitachi, this series that series...
I don't. Would have to be back at the shop in the morning. The carbs were on the bike, on the center stand, hose filled with no bubbles and held against the center of the float bowl. They're Mikuni. I can only find any acknowledgement of the existence of the carbs pictured through eBay. It seems nobody else has these or they're just ashamed ???
Yep. Using the same method. The nipple on the bottom (which has no overflow function) has a screw to drain and to test fuel level.
I've used this method on many different bikes before. This is the first time I can't find an EXACT reference to the carbs I have on this bike. Even searching the stampings gives me nothing. I've never met a more elusive set of carbs before. Maybe you will recognize them?
Hard to tell from that picture, but they almost look like a flatslide CV with accelerator pump. That would probably make them a BS series. Might be worth checking out viragoTechForum.com
40mm flatslides as I understand it. I searched online and seems that ViragoTech is probably the forum to join to see what's up. They also have a virago manual to download. Not much point in me joining it to download the manual, but could be a good source for you. Sorry I couldn't be more help.
I did download a manual for 81-99 models and it makes no differentiation between the carb models, so I'm feeling like something has been omitted here! Oy vey, off to join another forum maybe. I hired a new monkey, I'll let him go through our printed Yamaha manual page per page. Gotta earn that Ramen.
