Help PLEASE!!
10/10/12 at 08:02:44

Hi, I was wondering if anyone can help me as I'm now losing the plot!

I've got a 1997 LS650 that I've been restoring over the last few months, I've stripped it down to the frame and rebuilt it replacing various parts. I've changed the head gasket, replaced all the gaskets for the the covers etc, stripped the carb and put new jets in and the white spacer mod, installed a verslagen cam tensioner, forks rebuilt, front brake rebuilt, metalwork respray and loads more. However i've now got a major problem.
After roadtesting the bike and it running sweet I booked it in for MOT, the day came and I got a mile down the road and the b##tard thing cut out and I couldn't start it. Angry

I came onto the forum and checked out what it could be (Cos this forum's worth its weight in diamonds!!) I've performed the vacuum pipe mod/test and run on prime, I've checked the spark which I wasn't happy with (I had a new Iridium plug in when it died so I put a new regular plug in) Put it back together and it ran great.
Tooik it out for a test ride today, first 8 miles around town ok (no more than 30 mph) then took it on a dual carriage way, first 2 miles at upto 50 mph ok, coming back took it to 55 - 60 and the feckin engine cut out!! Couldn't start it again so had to push it the 3 miles back to the workshop! :'(

Got back to the workshop, checked to see if fuel was flowing from the tank, YES, checked to see if fuel was in teh carb by loosening the bottom bolt, YES. Engine turns over, bike WON'T Start.

HAS ANYONE ANY IDEAS??????

Could it be the coil that's dying/dead or anything else electrical??
Could it be a carb problem??
Or is the bike just out to make me greyer and more grouchy??

Any help would be greatly appreciated. Many thanks

In order for an engine to run...it needs 3 things. Fuel, compresson and spark. When an engine stops running....find out which one of those is missing before you tear anything apart.

Compression is easy to test.......put it in gear and try to push it, or use a compression gauge.

Spark is easy to test.......pull out the spark plug, connect it back to the wire and rest the plug on the head, and crank it over and watch for a spark. You could also use an inductive timing light and see if you get a pulse on the light.

Fuel Flow....sounds like you did that check and the fuel is getting to the carb.

If the bike is not running right now.....check the spark and let us know if you have a spark or not.

Reply #6 - 10/10/12 at 15:48:56 As mentioned, check connections, specifically the white/orange wire. I've seen the same issue in failing coils and condensers. They may operate normally for the first 15-20 minutes of the ride, but once they reach a certain temperature they fail. Next time that the coil fails, test the spark again.

Thanks for all the advice guys, much appreciated. I've got it all sorted now (Fingers x'd) the wire from the generator/stator was trapped between the battery box and the belt, green wire totally rubbed thru!
Wire musta popped outta the airbox recess when I re installed the battery box Huh

Off for MOT tomorra.

PS, does anyone know where to get a Raptor 660 petcock in the UK??

Cheers again, DT

Good to see you've got it all sorted out!

http://www.ebay.com/itm/Petcock-Gas-Valve-Fuel-Switch-Yamaha-ATV-Raptor-YFM66...

That's one of many on ebay that have free standard shipping worldwide. Simply search for "raptor 660 petcock" then click on advanced search. Scroll down, and you can select to show only items that will ship to your location. As always, confirm with the seller that they will indeed ship to your location.
