  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

250-500cc 1992 WXC 360 wont start

I recently came across a 1992 WXC 360 for 300 bucks. It was missing the ignition controller so it didn't have spark. I ordered the part and I installed it today. I cleaned the carb, changed the oil and the spark plug, cleaned the gas tank, checked the reeds, and filled it with fresh gas. the bike wont start. whenever I kick it over it just stats for a second, or just pops. I have tried adjusting the air intake screw, and it still wont start. I did a compression test on it and it was around 145 psi (I don't know what it is supposed to be at). I tried bump starting it and it still would not start. Any ideas on what i should do?

Damn, that looks like a steal at 300 bucks!

Anyway, a couple of suggestions if you haven't done these things already:

Check for air leaks (carb boots nice and tight? carb top secure?)
Check carb float level
Remove spark plug and confirm good strong spark
 
is that gas/oil spooge on the ground? i bet its flooded..take the pipe off and drain it, crankcase is probably full.
might want to verify you have blue spark too. does this bike have a kill switch? it may be causing partial gounding...plug cap ok? usually where it attaches to the wire it gets weak..
 
somebody might have monkeyed with the timing
back to basics
pull the tank
pull the plug, is it wet or dry
while it's out check your spark
 
so I pulled the plug and it was wet, put in a dry one, checked the spark and its strong and blue. While the tank was of I took of the carb again, and there was some dirt in the bowl so I cleaned it again. Put the carb back on, and checked the spark one more time. still wont start. I noticed some small cracks in the carb boot when I took the carb of but none of them went all the way through the boot so I don't think air is leaking in. Im wondering if there might be something in the pipe that is plugging it up. the bike according to previous owner, sat for a very long time.

was the plug wet with gas or oil
if it's gas check your needle and seat had that on my 92
if its oil you will need to flush the bottom end
 
first order is to check your needle and seat to be sure it's sealing
if so you will need to check your timing
 
Bike has an MA plate on it, I'm in MA as well. Good find, I never saw this on craigslist or anything..

When trying to start, does it back fire or anything, backfire through intake? Choke operating properly?
 
if its not starting currently, its flooded badly and will keep wetting plugs..dont be surprised if the pipe has a quite a bit of fuel in it..
ive tipped them on their tail and watched it roll out with the silencer off.

When ever I kick it over it over it either backfires or pops. When I cleaned the carb I cleaned the choke too so I im pretty sure it is working right.

The bike was part of a package deal with an 1987 XC 250. According to the guy I got it from, neither bike has ran since 1997. The fact that all I had to do to even git it to backfire was clean the carb and get a new ignition controller, was surprising. The 250 had actually been in the guys climate controlled basement so, it 250 xc.jpg
 
oops, forgot to finish my sentence...So it was really clean and started after I cleaned the carb, and changed the gas
