Rebuild '84 aspencade carbs

Postby Mark1537 » Fri Jan 01, 2016 12:58 am



I bought an 84 aspencade a couple years ago. It ran well for some time, then developed this annoying issue where if I leave the petcock on all night, in the morning, one cylinder is flooded and it will not run right even if drained. I assumed it was a float getting stuck at first, but it would have to be stuck down in the empty position. Anyhow, I bought the Randaak carb kit and decided to rebuild them myself. I've never rebuilt carbs but we all start somewhere and the instructions are detailed. But once I removed the carbs I was baffled. Upon hours of research, this is what I have found. 3 of the 4 carbs are from a California model with emissions equipment. The extra vacuum line is plugged with a hose and what looks like some rtv. Because it was running well to begin with, I ignored the oddity and rebuilt them, I cleaned them thoroughly and it ran beautifully upon reinstall. But the problem persists. It floods if left overnight with the petcock on. And is not rideable for a day. I don't want to constantly run my bike out of gas every night in order to ride it to work. So I'm thinking I'm just going to buy a set of carbs from eBay and have someone who knows what they're doing rebuild them. I can R&R the carbs and will buy all parts needed. If anyone can recommend someone in the southern California/Riverside County (or nearby) area, I'd be grateful. I want someone familiar with THESE carbs. I hear they're not like rebuilding a carb for a Chevy. Thanks.

Have you replace the needle valve and or seat yet. The one that shuts the gas off when the float rises. Checked the float level and
adjusted. Make sure float, floats and not sink. those Are the only 2 things that keep it from shutting off unless there is trash between the needle and seat. No I dont know any rebuilders in that area.

consider the "keep it simple" factor. one carb floods, im going to assume that you replaced the float needles and seats and measured float height. is it a stock fuel pump with correct pressure?. since it does it "statically" remove the fuel cap after you ride and see if that makes a difference, possibly to much pressure on the vapor recovery system forcing fuel past the point of least resistance.

The kit you bought if I remember correctly does not come with float needles. You can get kits for less that last 30 years from honda for about 30 bucks a carb. Southern powersports has them as well as I'm sure others. I used these kits on my 86 (same thing for most part) and have had no problems at all. I know when you pay A LOT for his kits all you get is rubber and he says to use your old needles. Now if you buy cheap china stuff I would agree with him, but stock Honda is hard to beat.
Like was said already, if your floats are good it can only be the seat/needle assy or incorrect float adjustment

Hey guys thanks for the replies. Like I said, I was new to carbs. I'm at a point now where I just want to get them redone professionally. But I'm having trouble finding someone willing to work on it, and that seems like they actually know Goldwings. I want someone who's going to do it right. So what I'm really looking for is a recommendation. I'm in the Hemet area in southern California. Anyone within 100 miles that can take it on would be appreciated.

Sure these guys are more than 100 miles. Randakk Cycles says, these guys are one of the best GL1200 carb rebuilders. Motorcycle Diagnostics, Stu Oltman, Phoenix, AZ. 408-363-5486. Im sure it comes with a price too. He may know of someone closer to you.
