Wont kick start but will bump start

[Blanky86]

I have a 2002 Banshee mostly stock.  Last seasons was my first season with it, and it was running fine for most of the season.  Now I can not get it start by kicking it over.  I can bump start it once it is warmed up i can turn it off and then kick start it, but that intitial start up it has to be bumped.  I am not really sure where to start? Or even what to look for?

How is your spark? How's your jetting? Have you checked compression? Filters clean?

[Blanky86]

There is new spark plugs in it I pulled them and they are sparking. Air filters clean.  I am not sure about the jetting, I cleaned the carbs at the beginning of the season bike ran perfectly for several trips, and from one trip to the next is when the problem occured.  Would compression matter if it bump starts?

Check compression...dont even bother looking any where else until you check compression

time for a top end rebuild bud.

[BUILDER]

Yep you have a wore out topend. Check compression and get back to us.

[Blanky86]

Ok thanks guys

[oldskool]

My guess is low compression, or did somebody already say that?

[Nieskes]

Check your valves.

[03DMshee]

^^^^^^fuck! I forgot all about the valves!

Like some of the other guys have said.....it sounds as if you need a top end rebuild.  Your compression should be in the realm of 125psi per cylinder on a fresh rebuild.....at about 110 I where you start having problems kick starting them.  Yes you can still bump start a bike that is that low....main reason being because you can gain that much more rotational force and speed. 

 

My suggestion to you is to get yourself a Clymers manual and do lots of research on here....maybe even see if you can find someone near you that is on here that wouldn't mind giving a hand...

Thanks for the feed back I picked up a compression tool from auto zone and going to check it this weekend during my turkey coma.  I also looked at top end rebuild kits ranging from 130-260 dollars.  I see that a lot of guys use wiesco over others are they just a higher quality kit?

[oldskool]

 Wiseco should be better than Namura. I've used both with no problems. Just read ad carefully, most time price difference is what all you get with kit.

pistons,gaskets,rings,wrist pin,circlips,needle bearings

If you're gonna do a rebuild and the cylinders don't need bored, you can't use the wiseco piston or any forged piston if you currently have a stock or other cast piston. If you don't need a bore you can probably get a stock replacement cast piston (Namura, etc.) and hone and put it in. Just FYI.
