Well got another one for the elders here. I recently picked up a Honda Trx 250
in pretty rough shape. Brought it home cleaned it up if thats possible. Motor was
seized, Pretty bad shape. I unseized the motor, got it to spin over, Got it to crank on its
own with the start button. Got neutral light, but no spark. Fuses good wiring is old but looks
intact. Went to check cdi box, here is where the problem lies, I dont know the year. The last one
was under the plastic on the crossmember, this one has none. Looks like a sticker was there at one time.
I checked the left side of frame by foot peg and nothing. Cant find any vin number. I need to know the year
to try to locate a cdi. One clue is this one appears to have 2 cdi boxes. One is a little larger than the other but
plugs look identical to eachother. One has green connectors and the other has white connectors. Is this only
on certain year model that has duel cdi boxes? I also need a download for a trx 250 Im thinking its about a 1985 or 86
but just a guess. Before changing i would like to check some voltages but need a manual for this. Any guess on how to
identify and or get a download for this one would be great. Wont let me post pics only .08 MB Down load available. Thanks in advance Az
Hi all, new to this forum so thanks in advance for the help.
I have recently brought a 2013 power steering fuel injected foreman 500.
It has a crack in the front casing and was running rough. I have since replaced the front engine casing and this has made no difference to the engine performance.
It starts and idles but bogs down and starts to die once throttle is applied.
It maybe be but it also sounds very load.
I have uploaded a video link of it.
We are starting this topic so that members can share their view about ATVs; what they are used for, types, etc. This topic is intended to help new members and visitors and generally those that don't know much about ATVs and would like to learn. So anything you can add to this topic that you feel would benefit a new comer, please add a reply..
Below is a quote from a response to similar question from yesterday:
"Easiest thing to check is trash in the main jet. if it idles fine, then the idle circuit and low speed jet is clear. if it bogs off idle that's when it's transitioning to the main jet."
I will go ahead and open up the carb and check the main jet, but please respond to this post as if the main jet is squeaky clean.
Below is my post:
Only starts and runs on Full chock.
Does not matter what position I have my "mixture" screw. Tried it at zero, 1 turn, 2 turn, up to five turns. Spent a few hours confirming that the position of the mixture screw does not resolve issue.
Runs great at idle and if I slowly engage throttle, it will rev up as expected. But, quick rev up or when I am trying to drive it, it spits and sputters and looses power.
I also use a propane bottle and did not find any obvious leaks, and the vacuum port is hooked to fuel peacock and I also made sure to simply block the port with my finger to see if that would resolve the issue.
New Carb (after market), New Coil, Fresh Gas. No leaks at manifold boot, hot battery. Good gas flow. Runs too good to be a valve issue, or cylinder, great compression.
I can move the choke out a tiny bit, and it will still run, but will still bog down when I try to power it up.
I also have a 250 trail boss Polaris that I require to run at full choke, but it has power at all throttle potions.
I suspect it is running rich as the choke is on, but will not run with it off.
Any details would be appreciated.
