    Been absent for a while, but I got a new project!

    Hey all! Been some time since I've been on here. A lot of things have changed since then but i'd like to show off my newest project! All I know about it is that it's a two seater Carter frame with full suspension, torque converter and dual band rear brakes. It has a few obvious issues like the...

    Adding a battery to a mini bike

    Hello all, it's been a while since i've posted anything and I hope this post is allowed since its not gokart related. So I just got a trailmaster mb200 a few days ago and man I love it! I want to add a battery to the system to keep the headlight on all the time. I already have a small...

    Custom pedal stop

    So i'm making a pedal stop for my Murray Explorer (going to a 22mm Mikuni soon) and I just cant decide what size of bolt to use as the stop. I haven't made a hole in it yet, I want to get everything figured out before I start drilling and welding. I would also like to trim the metal so it's not...

    What frame is this?

    So I might be able to get this 150cc gokart if i'm lucky. Its been sitting in a small gas engine yard for 3 years now and someone recently stole the carb off of it apparently. Literally everything is locked up tight as a drum, even the rack and pinion steering. I was wondering if its a GY6 and...

    PZ22 and Briggs intake

    What do I need to do to get this combo to work? Its an OEM B&S intake with a PZ22. Should I grind on the area holding the square nuts in so I can take them out and use regular bolts? Thats what it looks like I need to do but I want other opinions

    Valve seating question

    Is this an acceptable place for the sealing ring to be on the intake valve of my 5hp B&S? I still see a small ring of unground metal at the edge of the valve head so I assume its good to go. I know that ideally the ring should be close to the center (Not sure why it uploaded the pic sideways)

    5hp B&S coil question

    I got a simple question here about a coil for a 5hp briggs. I need a new coil but I want one with a connector for a killswitch wire. Is this the correct one that i'm looking for? I'm just now learning about briggs motors and want to be absolutely sure I have the right part

    6hp Tecumseh question(s)

    So i'm fixing up my 6hp Tecumseh and noticed that it has 3 wires coming off the coil. Which wires do I extend so I can move the killswitch closer to me while driving? Also, when I pulled the side case, the governor weights were destroyed and just laying in the bottom of the sump so I pulled the...

    5hp B&S teardown

    I thought I would share some pictures of the teardown process. These might be hard to look at for those who love Briggs motors. I'm going to remove and inspect the rotating assembly so I can send it off to a buddy who has a spare block and parts. He can build me a good performing motor for $50...

    Head rebuild

    Im in the middle of trying to rebuild my 212 hemi head with new valves and guides but I can't find any valve seals that will fit my new 5.5mm guide and intake valve stem. Its not a racing motor its just an offroad/trail riding motor. I have to have a seal so my motor doesn't suck in oil through...

    Hemi head rebuild

    Why is it that the hemi heads on a predator 212 have a seal on the intake valve guide but not the exhaust guide? My dad the engine building expert told me that the exhaust guide needs a seal so my piston doesn't get oily carbon buildup on it after an hour of run time Heres a picture of my head...

    Driver pulley rpm limit?

    I finally found a long flat desolate road to test the top speed on my stage 2 Murray Explorer with a 30 series TAV and governor delete. It was revving quickly from 3,500 to 5,000 rpm then it just stopped revving and took a long time (probably another 1/8th mile) to go from 5,000 rpms to 5,100...

    Cheap tach issue?

    I have a cheap one button tach on my Stage 2 212 that i recently built. It was reading fine with the stock flywheel and tach set on 1P1r (one spark per revolution). I have a billet flywheel now and every now and then it will stop reading, then come back a second later. Im wondering if I should...

    Head stud torque question

    I just got a package of head studs, valve cover studs and side cover studs from GPS. I haven't seen any other post on this so my question is. Should I follow the torque specs on the bags or follow the factory bolt torque specs? I've included both below so y'all can give me your opinions on this...

    TAV destruction

    So a thing happened while I was out riding my Murray today. Somehow I sheared the welds on the stationary sheave and had to push my kart about a 1/4 mile back to my shop to replace it. Luckily I had a new spare from GPS. I only have a stage 1 kit with 18lb springs and the belt is still new. The...

    5hp Briggs questions

    So i'm getting ready to clean up this old 5hp Briggs and get it running again after sitting out for a couple years. I'll be getting a new carb and inspecting everything inside. My main question is, what is this assembly under the tank? Is it governor related? Can i remove the governor and this...

    Possible springer front spindle issue

    So I replaced my front wheels and tires a while back and while the front end was in the air I noticed that one side of my springer setup isn't really doing much with that big gap at the top of the spindle. Does this have anything to do with why the left tire comes off the ground when I turn...

    Manual caliper adjustment

    I finally got some new brake pucks for the murray I got but the kart still doesn't want to stop. I can still move the kart with my foot all the way down on the brake pedal which I know isnt right. I cant find any way to adjust these calipers, I tried earlier today with no success. Should I buy...

    Need advice on a future 212 build

    I'm looking into building a Hemi predator soon. I'd like to get a HOT265 cam, 22lb springs, Billet Rod, Billet flywheel, a header and a real Mikuni VM22. I haven't seen anyone else run this combo and i'd like to know if these parts will work together. My goal is to have a motor that will run up...

    Murray Explorer TAV cover options

    I have a question for anyone with a Murray Explorer. Will a replacement TAV 30 cover from GPS fit on my TAV plate that bolts to the side cover? If so that would be awesome! I'd really like to cover the pulleys up after I put the correct belt on to keep sticks and stuff away from them
