Honda Spree and Elite 50 Forums

Starting a new thread this time. I have a 1989 sb50p, thought I needed new bearings on the crank because of a funny noise in there, tore it apart and found out it was actually the gear in the oil pump making the noise. But since I had it apart and an extra pump, changed that out along with new bearings.

Got it all back together (ran before I did this) and now I can't seem to get it to start and worst part of the entire process, I can hear that oil pump gear making the same noise.

I have good compression and spark, had the carb cleaned before I started this process, drained all the wrong oil and put in the Honda stuff.

Any help, suggestions would be much appreciated.

doulbe check and make sure like your fan shroud aint rubbin on nothing. i didnt know u could hear the oil pump?? as for crank bearings....u just know when thier bad. ive herd lots of spree/ elite engines that are junk. im thinkin how to describe the noise.......spinning a bicycle rim real fast.

Nothings rubbing, the noise comes when I wiggle the flywheel back and forth, but the pumps working, I pulled the tube off the carb and turned the flywheel and oil was coming out the tube. But the not starting has me baffled. I took off the head gasket, cylinder/piston, no oil down in the crank case, everything looked good there. The magnet on the CDI was a little rusty, so I lightly cleaned it with sand paper, definitely improved the magnetic ability, quickly stuck to the flywheel.

Could use any suggestions you guys can come up with.

Thanks!

I just had a problem with my ped not starting and I took it to a mechanic and he said that my crank shaft was shot. I owner before me ran it so long with a loose belt that the crank shaft teeth got stripped down causing the cluth to spin but not the shaft. I don't know if that will help but thats all I got.

That stinks, fortunately I don't have that, crank is turning fine, piston going up and down, had a little trouble putting the belt side back together, took awhile to figure out since the back end had stayed in place when I took the crankshaft out but got it and it spins just fine. I fouled out my ngk plug, the local shop only had Autolight plugs, only getting a white spark going to call and have them order the ngk plugs. Is there any way to test a CDI? I had cleaned the air filter, pretty dry, think I'll add a little more oil to it might be getting too much air.

Thanks
