Bike shuts off when shifting to 1st

Just got my first rc and I am having a bit of an issue. Situation plays out like this...

Im sitting on the bike and I start it up. Starts right up with no issues. When I go to click it into 1st gear from neutral or 2nd gear the bike shuts off. Any ideas?

from 2nd gear?

if it dies only from neutral to 1st gear it's time eye the side stand switch.

oh, that's different.

if the bike starts in neutral and then you put it in any gear with the stand down it will immediately die. it's a safety switch down by your side stand. they commonly fail and i'm fairly certain this is your problem, but i'm not guranteeing it!!!.

you can either clean it and hope that fixes it, replace it, or hard wire the switch right out.

personally i like that switch but many take it out.

The sidestand switch is a safety device to prevent from riding off with your sidestand down, which could cause an accident.
The switch is a rotary switch that's held by the bolt that attached the sidestand.
It has a tang that's is rotated by the sidestand.
You can remove the switch and test it by connecting a continuity meter across the leads and rotating the switch.
At a spot on the switch, you'll see continuity.

Well i doubt its the stand switch. I tried it today and same thing. Then I got smart and realized that the clutch isnt engaging... which is why it dies when i shift it into 1st or second... any ideas on the clutch?

Have you found any leakage near the clutch slave cylinder?
Or how's the clutch fluid level. Maybe air's got into the lines.
Was the clutch recently worked on? Maybe it was not reassembled correctly.

i havent found any leakage. A few friends told me I should bleed the fluid and replace it. The guy I bought the bike from said it had a new clutch installed....

Wait a minute. You need to explain your problem better. You said when you put it in gear it dies. 1st of all is the kick stand down or not cause either way it sounds like its the switch, which happens sometimes its not uncommon.

Then you come out and flabbergast everyone with "my clutch isn't engaging" So let me ask you this....Does the bike jump forward when you put it in gear and it dies??? If so then yes you definitely have a clutch issue. If no then its a side stand issue.

the same thing happens with the stand up so I know it isn't the kickstand switch. When I go to click it into 1st it dies. If it had lurched at all I would of instantly thought clutch but it doesn't lurch. This bike has been in storage for years and hasn't been ridden at all. I have zero experience with these rc's... i have ridden gixxers all my life so this is something all together different.

Any ideas what the problem could be with the clutch? Maybe it just needs to be adjusted?
