Otis Posted February 19, 2004 Report Share Posted February 19, 2004 I had to get your attention somehow..... I'm havning trouble starting and keeping the engine running on my little Raptor. The bike will turn over, but won't start when using the electric start button. It'll only start by jumping, or bump starting it. (and) After it does start, you have to constantly blip the throttle to keep it from dying (even after being warmed up for 5 minutes). I'm not vary good at trouble shooting problems w/ this bike. Maybe someone can give me a hand. things i've tried already. #1 Charged the battery #2 adjusted the idle #3 kept the choke ON to see if it would idle after warm up Quote Link to comment Share on other sites More sharing options...
orion6781 Posted February 19, 2004 Report Share Posted February 19, 2004 i have had the same problem with my nephews lt80. It would only start from a direct connection from the battery charger. We rebuilt it, and it seemed to work for about 2 weeks then the same problem. I hate working on these small bikes. Everything is so compact. sorry didn't help!

bbluebanshee Posted February 19, 2004 Report Share Posted February 19, 2004 Put a banshee motor in it!! how long have you had the bike? has it always run like that? does it smoke alot? try replacing the spark plug. if it is bad, that will make it a lot harder to start.

evil Posted February 19, 2004 Report Share Posted February 19, 2004 what about the air cleaner ? is it clean ? is the fuel flowing good, no obstructions in the tank ? spark plug ? perhaps something in the wiring. a dirty carb ???? Quote Link to comment Share on other sites More sharing options...
Toomey Banshee Posted February 19, 2004 Report Share Posted February 19, 2004 Without a doubt your valves need adjusting. Very simple. My youngest sons Rap 80 had the same EXACT problem. I adjusted the valves and it starts by just touching the starter. Throw a new plug, clean the air filter and take the plate with the holes in it from in front of the air filter after you adjust the valves and you'll be good for another season of riding.

What I was thinking, I've seen that problem & cure myself. With any 4choke, I've always been sure to change the plug & clean the filter after break-in AND check the valves.

Otis Posted February 20, 2004 Author Report Share Posted February 20, 2004 Thanks guys. That's what i was thinking too(Valve adjustment), but wanted an EXPERT opinion.. I just don't understand why it would need one so soon. It's an 03 and has less then 5 hrs on it. Hey Toomey Banshee, you happen to remember what the clearances are? Thanks again guys!

fixitrod Posted February 20, 2004 Report Share Posted February 20, 2004 That may be why. The new parts fitting in with each other. My son has an old moto4 80cc and it has the exact same motor. You can let it sit for a month, touch the starter and it's running. Quote Link to comment Share on other sites More sharing options...

Otis Posted February 21, 2004 Author Report Share Posted February 21, 2004 Thanks for all the help. It was the valves alright. Adjusted 'em, changed the plug, cleaned the air filter, and she started right up. I was reading somewhere that the exhaust valves are known for going out of wack... My nephew thanks you too....
