Trx 90 Cold Natured

[shook]

Im working on a trx 90 for a friend, it is very cold natured doesnt want run at first you have to ride it for a while with the choke on and then its fine can you change the pilot in these carbs or do they even have one or would adjusting the fuel or air mixture help with this and has anyone else had this problem.THank=s for the help.

My son's TRX90 has to be ridden for about 3-5 minuites with the choke on, and then it's fine. It's not really a problem for us...but I guess you might be able to make it better somehow???

I just bought a TRX-90 for my kids for Christmas... and was trying to let it run a bit the other day, I also noticed that this bike is REALLY cold blooded. Is there a trick or a carb. adjustment/change that would help this out? Also, I wondering because of this bike not having a battery is there a way to hook up a headlight? (kinda like the old 3-wheelers) any suggestions would be very helpful.
Thanks in advance,
Rydogg

I've had the same experiences with my neighbors, it has to be ridden for a couple minutes before it will run.:rolleyes:

Yeah, my sisters 90 is exactly the same...but when its warm its fun to ride wheelies forever just don't jump too high shocks arn't too good ;) :D :eek: :p

Did your friend take the airflow restrictor thing out of the airbox? This caused my sister to not want to run

I took the restrictor out of my son's and it is still cold natured as ****.

Try running a a couple of rages hotter plug.this has worked for me before.i have the same problem with my 400 ex and it is a 2003 with only 6 hrs on it

ya, my friends 90 is a bit hard to start and has to run a good 5 mins, and if it is ridden hard @ first and you let it idle too long it cuts off ( over 15secs or so ) , but it is REAL fun can you can "manhandle" them lol
