Do you have wiring diagram for clocks? I have crashed my clocks and ordered new from eBay, and now I need to mess with wires, I got wire diagram for new clocks but can’t find oem gt125 lcd clocks diagram
DONE!!!
Ultrasonic cleaning, and slide needle mod has helped me
still will put jets if they will come eventually, but yes it runs now like a new bike
total spent on bike from buying 1600~
and now it’s in the best condition with new michelin tyres on (from previous owner who was a twat)black widow exhaust (same from previous owner)
spare engine with blown front cylinder (oh yes)
and spare carb (dirty)
could sell spare parts if someone needs it (just give me a message here)
Oil is on l level almost (as I’m waiting for 7100 delivery) so don’t fill it up at the moment
ive done what you said and clearly seen like oil was soaking from that seal what I’ve told you, so now I’m 100% sure it’s that seal
there was bubbles coming out and it’s wet in there, so means it’s coming out of there (not really much)
I just want my bike to be perfect so still would like to change that seal (I will email you right now)
I’m more then sure that it’s not valve covers (I made some photos)If it’s not clutch arm then I don’t know what it could be honestly, but if there is a seal for this arm then it should be it leaking nothing else isn’t it
I got my old carb (looking better than new one) for ultrasonic cleaning today, and ordered new jets from jetsplus two days ago (not sure if coming and if it’s not scam as ordered with Royal Mail 24 and it’s been two days already)
as soon as jets will arrive, I will get it replaced on my old carb with carb rebuild kit I ordered here
hope all of this helps
(also I remember that air fuel mixture screws on them old carbs was 2.5 on front and 3 on rear, should I do the same when will get all ready?)
nice to have 2 engines (got every spare I need and can get them for cleaning while riding on main one 😅)
so yes, will get spark plugs as soon as all gonna be ready
Oh sorry my autocorrect messed that up
k&n air filter
yeah I ordered baffle should arrive tomorrow
also jets and carb rebuild kit so as soon as arrives I’ll do all of the mentioned
one more thing I’ve noticed, if I’m doing cold start, it want me to turn the throttle 3-4 times so it can start (without choke)
Keeps idling fine on warm, but cold a bit hard so giving it a bit of throttle
aaaand, I know I shouldn’t do it but I did screwed in air fuel mix screws about 1 turn in and magic happened it’s not jumping on warm anymore but does on cold
last engine front piston and rings absolutely gone, I’ve opened it and was really surprised as it was just 9k miles
going to keep last engine for parts in case I need it
I will update you after my manipulations with jets and slide needle
Also just noticed another post about upgrading jets, if it could be a problem with this jumping on throttle
I got black widow straight piped exhaust and ktm air filter which also give more air
can it be jumping like that because of them two? And does it means I need to upgrade jets?
and if it’s possible what can I do temporary until I will get jets as I use bike daily to work and back
This is what I found when was taking out oil from engine (this is magnetic oil drain plug)


I didn’t see any smoke at 10000 rpms as I remember honestly, I did rev it on neutral but didn’t see smoke last days but what I do remember is when I was buying this bike, when the guy started it up I’ve seen a bit of smoke come out of exhaust but I didn’t gave it a reason for it to be smoke as it was about 8 degrees so might was just steam, same as in rainy weather.
I will keep you updated tomorrow. I’m really lucky to have you here Marcel! Thanks.
Well day was hard but I did it!
I took whole engine off the bike lol
i don’t mess up riding it until it dies 🙂
so, carbs absolutely needs cleaning and replacing (or upgrading jets and all of that)
I will take the head out tomorrow and see what’s going on with rings and piston it’s front one
i will get seals and all of new engine gaskets anyways to make sure and keep it going as I need it daily for next few years (haha)
and yes it’s smells petrol inside oil cap
So, I got to the air filter just to see what’s going on
that’s funny but, is there is any place where I can get new pistons and rings?
front cylinder fucked up
Front cylinder spark plug full in oil, smells with petrol inside engine, oil and petrol in air filter
needs an engine rebuild… spent grand on this bike 👍
So after 5 days of owning it, It’s seems to be working fine when warm. I don’t have enough money right now to buy all the filters and compression check tool, I will get paid on Friday and order all of the filters and will get to the carbs to see what’s going on.
so main problems right now is. 5 am in the morning about 5-8 degrees, it’s quite hard to start up, but with choke on and almost full throttle it starts.
rear cylinder seems to be always more colder than front one and when engine is cold I can clearly feel that one cylinder doesn’t fires up until 4k rpm
i use it daily to get to work and back, when I start it up at 2:30 about 13 degrees outside it’s start ups fine without choke but giving it a throttle
there is actually no smoke from exhaust so it’s might been just steam
Oil level stays in same position so it’s not going anywhere , so I don’t really think there is problems inside engine but I will anyways check compression later and will update you
and also just as temporary I put inside that wynns thing in fuel tank to see if it will change anything before I will get everything
and last bit! I’m not sure if it’s a really something but it smells quite more than should be with petrol from exhaust but it’s black widow exhaust without baffle fitted on
im not English (sorry for mistakes if there’s any :))
