Engine won't start

Postby basmith » Mon Aug 18, 2014 10:05 am



Hi I've recently had my GL1100 engine rebuilt. It ran perfectly for about 50 KM. I heard a loud backfire and the engine died.
Took it back to the shop where it was rebuilt. Took the head off and a valve was bent. Did no visible damage to the piston.
The guy at the shop then said the valve springs were at fault so they were all swapped for new ones. Bent valve replaced.
Timing belt and pulleys were changed in initial rebuild. Carbs rebuilt and synced as well. Stator replaced since it looked fairly black.
The compression is now good across the 4 cylinders. Timing is right on according to the mechanic. There is a good spark. Gas flow seems to be
working as well. Tried priming cylinders but no luck. Seems like it's going to fire and then doesn't. I'm getting tired of listening to excuses from the
shop saying let's try this and that. Each time costing me more and more. I would appreciate any thoughts or suggestions as to what to look for.

Thank you

Do you plan on taking the bike home and repairing it yourself or wanting suggestions to pass along to your mechanic.?
No mechanic should ever charge you for his "let's try this and see what happens" type of work.
I never accept the trial and error method as a chargeable time.
Pay for what they know.Your bike should not be a teaching project.

By your descriptions,a valve stuck...dumped raw gas into the exhaust and it ignited(pop).
The cause of the bent valve after 50km of driving....Perhaps a broken inner spring.??Yes they have 2 per valve.Or at least my 1100's did.
Either way,now that the compression is back and the spark is verified,bout the only thing left is carbs.
I would first "suggest" draining each carb and looking at what comes out.
Not only what but how much.
You may find water or trash in the fuel.Expect about a shot glass full of fuel in each carb.

By the way.Not every mechanic is 100% on every bike.
You could "suggest" he/she join this web site,post questions.
We're happy to help anybody.
It all about getting the bike going anyways...whoever works on it.

Back to basics fuel, spark, compression. start by pulling plug wires off the plugs attach a spare plug and look for spark as you hold the tip on the engine block, testing 1 an d 3 should be enough to test coils, and pulser. Next do a compression check..throttle all the way open should read 140 or better and be close together in readings..if that's all good...last test fuel..air box off spray bottle with gas or starter fluid can..and crank..ps have a fire extinguisher handy just in case. If that starts it = lack of gas in the carbs or blockage of jets.

This may sound kinda odd to some, but....to trouble shoot a .gl 1100 enough to get it started is elementry to most shade tree mechanics ..l don't mean to sound ugly, but I think I would be cautious of a forked pencil.... :roll:

Thanks for the posts
I've passd on the suggestions. I'll give them some time to try a few things.
Issue is if I take it back from them and it turns out to be something they had already addressed in the rebuild I will be on
the hook for repairs. They have informed me yesterday the charges are minimal at this point just paying for the new valve and springs.
