Iv Got a Yamaha YZF 400 and it a bugger to start if cold...! Any tips???

Question

I love the bike it's the don......... But a bugger to start.....

Answer 1

Bikes of this type just plain hates cold weather, it's meant to start in warmer weather. If you are storing the bike outside, not good. Store it inside a garage where it's warmer. Then it should start a little better and not act like an old woman.

Answer 2

could me one or more things. i would check ur plug. if you havnt changed it for over a year that might be part of it. another part could be jetting. also make sure that you are using the choke. if it is like most big bore four strokes then you should pump the kick start lever and then when it feels like it wants to fire kick smoothly and straight through while rollling the throttle. another option would be a hot start lever -essentially another choke.   if it is a real pain or just plain unreasonably take it to a shop and get their opinion.

Answer 3

some bike just are stupid at starting.

Answer 4

I would check your plugs they need to be golden brown, if they look black there's your problem, failing that keep decompressor in and kick bike half a dozen times get TDC then hopefully it will start.

good luck nice bike

Answer 5

thats 2 strokes for ya.

4 strokes arent as bad.

but any bike will be a trouble starter in cold weather.

before it is warmed up

Answer 6

first off after you wash your bike undo the 17mm bowl on the bottom of the carb and make sure there is no water or **** in there this can make the bike a pain to start turn the petrol on once youve taken it off just to flush it through then put it back on. when youve done that give the bike a bit off throttle then kick it over giving it no throttle at all this should work if it dont try giving it a tiny bit of throttle when kicking it over. hope this helps if i dosent you might have stretched valves or some over kind of problem like jetting

Answer 7

hey, ive got one of these, all you do is hold the decompression lever and kick it softly a couple of times to get gas into the carb. After i do this i kick mine really hard and it usually starts after one or two kicks

Answer 8

When you stop the bike turn the fuel off. this will stop it flooding. remember to turn it on again when starting. this can happen if you leave it standing, say overnight. also check the airflow. (filter/s) smallest thing with the biggest effect dirty filters. even K/Ns need cleaned. this is in addition to all the other advice given about plugs etc
