z50

Howdy. Hopefully I've come to the right place with all these questions of mine. I am currently building a 1995 Z50R with a KLX110 fork upgrade, +3" swingarm extension, and (possibly) a 140cc Piranha engine. At this point, I am starting to think about brakes. With a 140cc engine, I feel like...

I have an 82 Z50 that ran great but was starting to smoke so I put a new piston and ring set in and honed the cylinder. Set valves to 0.02 intake and 0.03 exhaust. However now I’m only getting 60psi compression. Bike idles just fine and runs great in neautral. But under load it can hardly make...

I just reacquired my 1987 Z50R from my brother's friend who has had it the last 20 years at a vacation home. This was done without my knowledge or approval but long story short, it was in great condition when I last saw it last and now it isn't. I got it new for xmas in '87 and it has great...

Hey everyone, new forum member and first post on here. Thought I'd share my Z50 restoration project Ive been working on during the winter. First time working on a z50 or really any bike for that matter. Aside for a 70's vespa moped lol. I picked up the honda from a customer for the great price...

Hey folks I am restoring a 1969 Z50 K1 to it's former glory. I need a battery box...Yes I have seen the ones on eBay from Vietnam but $110 shipped is steep and it will take 30 days to arrive. Anyone out there in the community that might have one of these laying around that they'd be willing to...

I have a 1973 Honda Z50 with an engine that is a mix of 1985 ATC70 and 1973 Z50 parts (the cases, top end, and transmission are ATC; the ignition, crank, kickstarter, and shift shaft are Z50; the clutch is a mixed bag). I want to install an ignition cover from an XR50, but I can't shift with the...

I am experiencing Neutral & 1st gear working, but the bike isn't shifting into any lower gear (no 2nd or 3rd). I think the drum stopper may be in the incorrect position, due to the shift arm being in the wrong position. I have read on thumppertalk that the flat side should be vertical and...

Greeting's everyone, I am new to the site here. I'll keep this short and sweet. Just picked up a 1988 honda z50 for me and my nephew (age 2.5) to have some fun on. The engine in missing the magneto cover, and it's seem's almost impossible to find. The clutch cover has a big slab of silicone...

Hello I'm having some issues with my 1986 Honda Z50R. I have discovered that there is a fuel filter/screen located inside of the gas tank. I'd like to change this filter as I believe it may be clogged. How is this filter removed? I have taken the petcock out but I cannot figure out how to remove...

Been getting worked by this lil eBay purchase carb in the tuning game so far. This OEM Honda ATC70 carb of mine has a periscope-like body hole pointed out in photo. It looks like it should be all good & to help prevent air lock or something. I have no clue & was looking for wisdom on what...

Hi, I'm looking for a z50jz frame 1979-1989 model. If you got one, please contact me. Thanks

Picked up a project Honda Z50a monkey bike where the PO cut into the neck of the frame to fit the OEM stock CT70 carb and intake to the 72cc upgraded top end(Z50 bottom end). Creative...Yikes. After the frame gets repaired, I will need to refit the carb to the engine & have read a few options...

I rebuilt this bike from a real heap. I bought a motor on Ebay, to replace the trashed motor. Disassembled and rebuilt with fresh paint and fresh new or near new parts. Both OEM and some high quality reproductions, but mostly OEM parts. The tank is a repro, but, if you want, I can replace it...

looked everywhere but everything I am finding is for a 4 bolt rim. My current hub's sprocket studs are stripped and after a failed attempt at fixing them i believe i am in need of a new hub. any suggestions where i should look?

I've done some research online and was looking of a way to wire headlight and taillight to my z50's. I do not fully grasp it but so far it seems the AC that comes from the AC generator must be converted to DC through a rectifier then the DC power can be supplied to lights. So I have a 1978 that...

I decided to build my stock 91 Z50r. I picked up a Piranha 140 complete engine setup, TB klx triple, klx forks and had a parts china bike laying around. I like projects, so I figured Id convert the Z to a single rear shock. I had a swingarm that was a +3 compared to the stock Z50. So I modified...

Hello everyone. I an starting the process of rebuilding or at least getting my childhood motorcycle up and running. The bike spent half a decade or more out in the elements and has not been started in over 15 years. I am just curious, If you had this bike what would you do to it? Also please...

Hey everyone, I'm new to the site here (well I've been on here quite a few times over the years, but just signed in) and I've noticed a lot of people, in a lot more places than just this site, thinking about buying a complete Piranha, Pitster, Daytona, etc. motor, or building their motor. 10 or...

I have a 2004 Limited Edition Freddie Spencer 50cc Monkey Leisure Bike in CB750F Colors that is in absolute pristine condition, it has extremely low miles (585 Kilometers.) This bike was given to me as a gift I've done some due diligence and it sounds like these were only available to be...
