Honda Spree and Elite 50 Forums

Alright here it goes been working on this bike for almost a year, and now it wont start. I had a bbk on my spree that somehow got a crack in the cylinder and caused damage to both the piston and rings so i got a whole new top end. In the mean time i noticed the crank on that engine was having trouble turning over later found it had crap in the bearing so i unbarried another engine i had laying around that had a good crank and turned over great. So i started the swap gears clutch pulleys and all. When i got the new bbk i put that one on and got everything put together. Compression is around 125 psi. Has good spark (meaning spark jumps over 1/2" to a ground and using ngk plugs no. 6's brand new). Im using a 19mm carb with electric choke along with the ct intake. I took apart and inspected the intake no problems, reeds looked fine and everything was operating properly. So a colleague told me the timing may be off due too a bad key. I inspected that cleaned an reassembled key looked great. Still wont start. I put mix down the plug whole and nothing. I inspected both crank seals looks great. Im stumped.... Anyone have any ideas??????

Try a different cdi u have one on the ur other bike give it a shot a vacuum leak would at least let it pop if u put gas in the spark plug hole.........

alright ill throw a known to work cdi on it tommorow and yea not even a pop....

the only thing i can really come up with is an itterminten spark issue so look for anything out of the ordinary...

im going to pick up a timing light today so do make sure of the timing.

you cood have bad crank case seal or the gap on the plug is to big ...

Inspected seals both looked to be in great shape no cracks no dirt no seperation... PLugs are gapped to spec.

the case seals are under the fly wheel ..if you have that off you no if the key is bad...
the spark plug is to speck put in at the small end of speck ..

As long as the wooduff key is installed right you cant have messed up timing. Cdi is my guess as well.

A timing light answers both questions. Don't forget that if you line up the timing mark at 0 degrees and the piston is at TDC you can confirm mechanical timing.

Yes SF as i said above i had the flywheel off and inspected both the key and seals, i also cleaned everything while i was in their.

I think I may have similar problems to you. I have a spree that sounds like it's in the same condition. Did you ever figure out the culprit and get it running?

No sir still troubleshooting to no avail.

Did you make sure the exhaust is free and clear and the filter isn't over oiled?
