This quad was a hot mess two weeks ago when I got it. I've been tinkering on it and have it running pretty good. It didn't have a pull start. I just got one and installed it today. Here's a little video of my first try at using it. Hope it's worthy of a "onya" from Mech! 🙂 IMG_3274_Trim.mp4

Mech..I'm betting the positions on the petcock, based on the symbols, are up is "normal" (taller standpipe), down is "reserve" (shorter standpipe), and horizontal is "off". That "hose opening upwards" is not connected to the carb. It disappears into the instrument panel and I can blow through it. I think it's what was connected to the original petcock valve.

Mech...I knew you would try to help! Thank you! Here are some pics...I do not have the vacuum petcock. Looks like someone might have replaced it already. There is a short piece of hose on the carb that is plugged. I assume (you know the acronym I bet...) that is where the petcock was connected. There is also a piece of hose, disconnected, that disappears under the dashboard. Probably the original petcock vacuum hose. What are the positions on the petcock shown?

I just bought this a couple of weeks ago. The oil sightglass was FULL. When I opened the fill plug, oil/gasoline LITERALLY gushed out and flowed for several seconds...FROM THE FILL PLUG! I drained it, changed the filter (no metal bits), and refilled with new oil. Opened up the carb and cleaned the float needle. Blew into the fuel inlet while manipulating the float and it seems to work. Buttoned everything back up and it runs good. Now my question...was the fuel getting into the engine because of a stuck float needle or is there something else wrong?

Operator error! With the rearend raised. it shifted through all gears while rotating the wheels! Thanks Mech! Now I just need to learn how to ride it! 🙂

As soon as I get the front wheels back on so I can try the rocking thing, I'll get back to you. Right now, stationary with engine off, 1st and 2nd make a distinct "click" when shifting. Further "pulls"/toe-taps on the shifter feel like shorter travel against a "mushy" stop...if that makes sense. No matter how many time I try shifting "up", two clicks down takes me back to neutral. When I have more info about "rocking" or even riding results, I'll post again. Thanks again for your help!

I have tinkered on a Chinese GY6 150cc. It stalls unless the idle is set high.

Never ridden two wheeler. Had a1983 Honda 3-wheeler for many years...similar "clutchless" shift. I just got this one last week for cheap. Trying to figure out the actual condition. I rode it just a couple of times before starting work on it. Crankcase was full of fuel...got that sorted out and cleaned the carb. Right now it's jacked up waiting on brake parts...cylinders blown in both wheels, right side didn't even have shoes! Not worn out or broken...not even THERE! While waiting, I thought I would try to figure out the shift issue. Just for background, I'm 65 years old and road submarines for twenty years. Former nuclear engineer...new to 4-wheeler maintenance 🙂 I certainly appreciate your help!

Are you saying de-couple the shift cable from the output shaft and rotate it to a new position and tighten back up? Forgive my ignorance... It won't shift when running/rolling, not just stationary.

All of the above...I just got it. It won't shift above 2nd running, not running, rocking...nothing. 1st and 2nd is a solid "click". After that, nothing. No matter how many times I pull up on the shifter or how hard, two clicks down and I'm back to neutral.

Got engine issues sorted out...kinda. Engine starts easy and idles smooth. It had gasoline in the crankcase...lots of it. Drained, changed, and fixed stuck float. Now it won't shift into 3rd, 4th or 5th. Reverse works as it should. 1st and 2nd click easy and with no abnormal noise. 4WD, superlow, and LOCK all seem to work. What should I check next?

Hello! New member here! Retired Navy Submarine veteran living in Georgia. I just picked up a 1998 Suzuki Quadrunner LT-F250 for CHEAP. Small 4WD double locker was exactly what I needed. It had LOTS of issues...gasoline in the crankcase, NO brake shoes, blown wheel cylinder, smokes BAD, only shifts into 1st, 2nd, and reverse, etc. Looking for all the help I can get to sort things out.
