    K1 ct70 stuck in gear

    I got everything cleaned up nice but I used a lot of brake cleaner, so I need to pop the bearings out and take care of them. Started working on getting the valves and camshaft out but the exhaust valve cover is stuck, and now stripped. Let the PB sit for about 29 minutes then got it hot and let...

    K1 ct70 stuck in gear

    Alright I’ve got the cases split and everything is disassembled. A small bit of rubbing on the inside of the case is the only damage I can find. I understand I’ll need to get new circle clips to reassemble properly, anything else I need to buy for the inside of the motor? Are the complete gasket...

    K1 ct70 stuck in gear

    I already took the points and could off, I can get the screws back in and pull from those though maybe. I can kinda pry up from the bottom side through the timing chain channel, but I don’t feel good about that.

    K1 ct70 stuck in gear

    Okay I’ve got the clutch and shift shaft removed. Had to drill out the stator plate screws as well, now the stator plate is stuck. Can’t get the brass small primary drive gear bushing off either. Im so close to splitting the cases to get everything cleaned up, hopefully it goes back together...

    K1 ct70 stuck in gear

    Still can’t get these 3 screws out of the clutch. Stripped one out so I started with a screw extractor kit but I’m not getting anywhere with that either.

    K1 ct70 stuck in gear

    Picked up a ct70 this morning. It had a lot of water in the motor, so I drained it and started disassembly. Head came off fine, it had been removed before, there’s red sealant everywhere. Cylinder head and piston and valves look okay but but there’s sludge on everything. Trying to take the...

    1972 ct90 Lifan swap

    Engine didnt come with any paperwork other than the shipping tickets that were all in Chinese. Came with an ignition coil wire and a cdi with the harness to connect everything. So far I’ve only connected what it needed to run thanks to the guide of a mechanic buddy. I’d like to get at least...

    Can anyone link what I need to do to get the lights working? I’m not running electric start so I don’t believe I need a battery, but I assume I need a converter, that’s what I keep hearing but nobody has said what it is or linked me to one. I’ve never messed with wires before and the guy that I...

    Side note; the Apache 2800 through 4800 fit great on the rack as a tool kit/wallet/lunch holder. I used a single lashing strap to hold secure it and it also stayed water proof when I tipped into the creek

    1972 ct90 Lifan swap

    I’ve got pretty much everything dialed in, went out last weekend on gravel roads for about 2 hours and ended up dropping it in a creek. Took probably 60-75 kicks to get back started but once it did it ran fine the 2 miles back to my cabin. Before I flooded it I got some good clutch control work...

    1972 ct90 Lifan swap

    Have a friend who is willing to help with the wiring. New rear suspension is installed from isvintage (site looked American, but turned out to be very Chinese). They’re much stiffer than the old ones and I have no rear tire rub when hitting bumps, but my front wheel is clipping the front fender...

    1972 ct90 Lifan swap

    I’ve had a few friend tell me that since there’s no electric start on this bike, I can just hard wire the electrics. They said I’ll need a converter but it should be easy. Any negative side effects of this?

    The part I ordered was called clutch dampers, the rubber bits in the rear hub

    Nate, I don’t know that it’s the wrong engine. The bolts all line up now, I was overthinking everything at first. It’s a Liffan 125 from t-boltUSA. The engine came with a magnetic drain plug and pulled out a fair amount of fine shavings, nothing major, I also wiped it and held it under the...

    Got screws for the rear section of heat guard for the muffler in this morning. Bent the old front heat guard to fit the shape of the new pipe *enough* lol. Also put the 1,000th mile on the bike and changed the oil after 46 miles on the motor. There was a good bit of metal shavings on the drain...

    I sanded down the inside of both rims and lines them with the band as well as tape on the rear wheel. Got the new dampers in and am having an extremely hard time getting the sprocket to fit back on the wheel.
