Question about 2006 KTM 560 SMR

1 Answer

Will not restart after being warmed up, it starts easy when cold.

If im in the garage and I start it after it warms up it will start but not as easy as when its cold, if I ride it it wont start while warm at all. I live in Salt Lake City Utah. I adjusted the valves which were very tight which improved its cold starting. The oil and filter has been changed and Im running it on 107 octane fuel. Last time I rode it was this past july I took it out and it ran good didnt try to ride it until Nov and it wouldnt restart while hot so I adjusted the valves. It also pops through the exhaust when the motor decelerates when I rev it and cut the throttle back and the motor decelerates but thats been happenening since I bought the bike.

After start it backfires, sputters then runs

Hi,when starting bike you put the chock on,remeber this is to make a richer mixture for cold start,so when you start the bike put put the choke off a little bit as it warms up,other wise wat you are doing is couseing it to floud,so again as the bike warms up put the choke off little bit at a time,all the best.

What causes my04 sportster starter to drag badly when i go to restart the bike after i have driven about 5 miles

When the bike is warmed up everything is tighter so it is harder to turn it over and the starter needs to draw more amperage so if you battery is weak it will not have the ampewrqage needed but also if the starter has defective windings they may fail when hot but not when cold so you will need to do some more testing to see precisely what is the problem.

Won't start when cold

The cold start valve could need replacing. Also when cold, condensate gets on the wiring causing it to run rough until things warm up. Try covering it up at night. Check your plugs are OK.

My Yamaha wr 250 starts well but when hot just konks out, the carb has bee cleaned the head skimed, new head gasket ect, could it be the stater plate ? does any one think they might know the answer ? Tony.

my man, tony, dudeski, im a yamaha mechanic in idaho. your problem my friend is a valve adjustment. your valves are loose enough when cold to run with some compression but when warmed up they become to tight...therefore not enough compression to fire. easy fix too.

Hi when bike starts from cold theres a knock/grind noise that the engine makes for about 15/20 seconds and then goes,when warm and restarted no noise she runs rearly well when warm or cold

that is because oil gets cool............there will be no problem when oil is normal..........nothin to worry about this........keep reving your engine

200° is quite warm...
If the engine wont turn over, probabily you have a bad battery, a bad starter or a bad starter relay, or bad connections.

A hot engine has more compression. If the full battery power doesn't reach the starter it won't turn over...
