Title: Bike stops every 60 miles
Post by: Kevs UK Raider SCL on Jul 16, 2021, 01:56:26 pm
We need some advice and info if someone in the Raider world knows.

One of the Raiders over here in the UK cuts out/stops after around 55-60 miles from a full tank of fuel.
I have checked the vacuum hose from the tank and it's clear, but the symptoms are similar to it being that type of issue.

It has a big air kit and today I removed it all and cleaned it all and reinstalled it.

Now, my question is this.... when the tank is full if gas, is the fuel being delivered by being gravity fed and does at some point when the fuel gets used, does the fuel pump kick in? Just wondered if the problem is with the pump.

It's important to say that the bike restarts straight away and you can ride it fine afterwards. It can ride a little rough at times but not consistently.

Any advice or answers is appreciated

The fuel pump is always delivering the fuel, no matter what the fuel level is.

When the engine stops, is it at an intersection, of does it stop while at speed? I know a few people had issues with a faulty clutch switch that would cause the engine to stall when they were almost stopped at an intersection.

It sounds like the fuel pump to me. It tends to act up more when the tank is low. I only ever had mine completely cut out maybe twice, but it would definitely run rough when coming to a stop.  It was barely noticeable on a full tank when it first started going bad.

What has been done to the bike recently?  Definitely sounds like a fuel flow issue.  Was the tank removed?  Maybe the shutoff valves weren't fully re-opened, and just enough is making it into the sub-tank then running dry.

If that was the case the low fuel light would come on since the sensor wouldn't be covered with fuel - maybe the tank vent is clogged not letting air in the tank to let the fuel flow into the sub-tank.

Maybe - certainly sounds like a fuel supply issue.  If it were a car, fuel filter would be a likely candidate.

My guesses in ascending order of difficulty/complexity:
1. Vac hose clogged. When the bike stops, open the fuel cap and listen for a hiss indicating the tank is under vaccum.
2. A quick-connect is not fully seated. I know it was a common issue on my Warrior, so I'm assuming the Raider uses the same fuel hose quick-connects.
3. Fuel filter is clogged.
4. Fuel pump housing is cracked.

If all that is fine then I would look to ignition coils. I had a nighthawk that ran great but once the bike was really warm it would stuttor and almost stall. Turned out one of two coils were bad, but only when hot. I rebuilt the carbs twice and sync'ed them many times trying to solve that damn issue before switching my attention to the ignition.
