|#1: New here, 535 runs for a while, then
dies (SOLVED) Author: valenzano, Posted: Sun Jun 06, 2010

Hi everyone! If I'm not doing
this right, I'm sure you'll let me know. I'm new here.
I have a 1987
I've been reading the forums for a while, and I haven't found
something that matches my exact situation, so before I start taking the
carbs apart, which I really am not comforable doing, I thought I'd ask.
It ran well when I bought it two months ago, except (I just
realized this) the choke was always in the 'on' position. (Dies when I
It's not running so well now.
story: It first cut out while I was out riding, and lost electrical power.
It had a new battery, so I figured it wasn't charging. Found a
fault-finding flow chart, followed it, and determined that the
regulator/rectifier (RR) was bad. Bikebandit.com wanted something like
$212 for it, so I read up on here and got one from a junkyard 1984 Honda
Shadow for $4. Fixed! But...
A couple rides short rides later
(about 35 miles) It cut out again, mid-ride, and died. This time it still
had electrical power, and cranked just fine, but wouldn't start until I
let it sit for maybe 20 minutes. Then it would start and run for a short
distance, (like, 400 feet) then die again. The throttle response is
choppy. As I twist it it first sort of bogs, then races after it reaches a
certain point up to full open, but then it bogs completely and dies. If I
try to ride with throttle about half open it surges forward
intermittently. Also, makes subtle 'puff'/hiss out of intake that I didn't
notice before. (I have the dummy tank off.)
Looked in the float
bowls, everything looks nice and clean. It's got good electrical, unless
there's a short or something, but the battery's charging. It seems like
fuel starvation or carburetor issue, maybe? I checked fuel filter, it's
very good, no blockage. I ran some 93 octane from sunoco with about a
third bottle of gumout carb cleaner, which should be enough to treat about
7 gallons, cuz the bottle says treats 21 gallons.
I've run about six
gallons through since I got it, so gas should be good.
okay, but I got new ones today so I can read them better. (NGK's, like the
Seems to be firing on both cylinders, at least most of the
time, because they both get warm while it's idling.
I took the gas cap
off, no change in idle. Doesn't seem to be a vacuum problem.
seems to be working, unless it fails once it warms up or something.
(Although, it still clicks to pressurize the system when I try to start it
immediately after the bike dies.)
Both plugs have spark.
can't seem to figure it out. Anyone have a suggestion?
