We aquired this Quad that shows very little use but had been sitting for a while. I have it starting easily now - but it does not have much power at all. It seems like it's loading up with gas and bogging down. Spark is good - have replaced the coil and plug - replaced the carb with a new one and still the same issue. Thoughts?

I have worked about 4 weeks on my Griz600 and have burnt 2 CDIs up ! I added a wire harness and stator and It starts but runs erratically like spark timing is off ! So I would like to try another CDI but I don’t want to Pay an arm n leg ! Anybody have one ? Thanks

I have been trying to get my Griz600 running right for 3 weeks ! Grandsons used it and it quit running , no spark ! New stator etc and started but ran terrible ! Found a burnt capacitor on cdi . Installed used cdi and burnt it also but ran same as other cdi . Came to conclusion wire harness had short so stripped it and found some bad spots fixed and another cdi ran terrible again ! Bought another harness and same rough running ! Checked spark timing with light (put tdc mark on case and on pull start hub) and when it starts timing right on but will jump 25+° retard ! When timing is on tdc marks it has no power ! The stator is new but I am wondering if the pickup coil is triggering incorrectly ? Also had top end apart when I first started having trouble and although rings were good I installed new rings . Also new timing chain and check the valves , they were good also . It kind of seems to boil down to the last stator I installed new ? I have done trouble shooting on quite a few cars , trucks , dirt bikes and ATVs but this is frustrating me ! Just wondering if anyone has any ideas ? Carb was new last yr and I checked it ! I IMG_4379.MOV

IMG_4272.MOV Originally had my griz600 stop running and then wouldn’t start ! After testing all coils , valve lash , compression (115psi) and all tested ok I bought a used cdi . After cdi install it still wouldn’t start (no spark) ! So even though the stator , pulse/trigger and charge coils check within good range I decided to switch the stator etc ! It started but It is very unresponsive on throttle and acts like it is running in 2 Different spark timing ! With slight throttle it will take off good but instantly go into a very different running mode with no power like timing very retarded but it will switch back to running good for short period then bad again ! Since I replaced the stator and it started I then decided to install the cdi I replaced and it did the same thing ! Also I noticed the Used cdi I Took off had a capacitor that had swelled and extruded from the back of the cdi . I had always heard and I believed that when these CDIs go bad they machine will quit and will not run . Is that true ? I also checked the cam/valve timing and its ok ! Checked with timing light and it does fluctuate on idle ! I am thinking I have 2 bad CDIs . I also switched the trigger Coil wires and would not start then . Man , this thing ran good before and I am confused ! Video below may help ! IMG_4272.MOV

New arctic cat owner, I've read alot on the gauge issues, but let me say I have power, good ground, the aux also has power, the memory has correct voltage but no output of any kind. Only the LCD color works. I have also fully removed EVERYTHING and cleaned it all... what I still possibly have a cut wire knowing that I have good power to the back of the plug and good ground to the back of the plug but no outputs of any kind?

I need some advice on my 700 kingquad. I recently went out into some deep water (not sure if this is the issue or not) I did not submerge past the seat all the way, however I did wheelie out of it with the back end submerged for 5 seconds. I realized after I did this that you could hear the engine going up in rpm's but there was no power to the wheels after a point. You could only hear the whailing of the engine. Could someone lead me in the right direction... basic knowledge would be to check air filter, belt housing for water, spark plug. Otherwise I am at a loss. Thanks in advance!

Do you think a King Quad 300 would have enough power to move a set of tracks in low all the time?

i bought a 2004 raptor 660 and the guy had jeted it and it would start but bog down so i replace the jets the jets were 140 but everything was stock so i put stock jets back in. well it starts good and idle great. but when u put in gear and try to take of it has no power it seems like its in neutral, its goes but slow i push the gas and all its doing is reving up. i shift gears, all gears go in perfect but still no power... HELP!!! plz

Hey so I just bought an 01 raptor 660r 46.4 hours on the bike. Anyways I road it a year ago and it has been sitting since then so I bought it from dads friend anyways I changed the oil oil filter new gas and some sta bil. Anyways it feels like it has no power from what it had when I last rode it. It will get up and go but it just doesn't have the torque I remember it having.. any suggestions

i have an 07 400ex that i want to spice up a little. ive already decided on a jet kit and exhaust and maybe a cam. what brands give you the most for your money? and would a stage 1 or 2 cam be better? and is there anything else i can do and gain more?

I got my son a powerwheels quad. We bought it off a member of this site (wonka). Thanks!! It's soo cute. I'll take some pics soon and post them so everyone can see. He just turned 1 today!
