You do know, I hope, there is a way in that requires no tools? Turn forks to left, lay on ground (if an old guy) on machine right, look up to back of ignition switch, grab cable housing on bottom of ign. switch and pull along cable axis as best you can. Repeat yanking on cable housing until seat unlatches. Take two aspirin and call me in the morning!

Thanks Karl, this trick saved me a lot of time and frustration.
One latch got stucked (second one was disabled long time a go), after a couple of days i found this trick and worked like a charm.

It was the best possible outcome, nothin broke, nothing snapped .. only thing that happened is the main screw on front pulley axle came loose so that front pulley fins made contact with CVT cover. I have inspected everything, no major damage, put everything back, after putting two drops of loctite on front axle nut.

Thanks for help !

Downtown 300 / Sudden loud noise from engine
« on: June 04, 2022, 09:37:22 AM »
Yesterday while i was driving all of the sudden loud noise started coming from engine, it sounded like it was construction worker breaking concrete. I turned the engine off and pushed the bike back home. I have enough fresh oil and new filter, checked the coolant level - all good there.. Now when i start the bike i hear this noise..

My guess is that something is wrong with valve clearance job. Maybe tolerances are bad, and get worse when engine heats up.

Changed the bearings in both front and back wheels,

In the process i managed to overtighten front axle pinch bolt and broke off the part of the fork .. can this fork be saved?  welded ? drilled? tapped ?

I need help with one thing though, when i removed the front wheel i have used the opportunity to check the wheel bearings.
They seem a bit hard to turn, but i don't have any experience with motorcycle wheel bearings .. i know they turn much, much easier when i played with them when they are new and from box ..
I'll post a video of me trying to turn them, there is a mark on bearing so it's easier to see the speed they are turning.

I have changed fork oil, no vice, no help.. it was tricky until i stopped trying to remove snap ring with screwdriver and used utility knife at this step

 - it took a second only .. using utility knife for this operation should be in kymco manuals, it was so easy..

This was some time ago, i have painted oxidized black plastics. I could have done a better job, but for the time & money invested i'm more than happy with the results.

I've used matte black paint for plastic bumpers in can

Replaced broken plastic CVT cover, bought used part, from bike that probably crashed sourced from Italy, filled up damage with
F211 Bodysoft - HB Body, sanded with 220 - 400 - 500 grit sandpaper and spray painted from cans.

Things to be done by service manual

I noticed you haven't mentioned changing oil filter, i would do that - they are cheap and easy to replace (make sure you are turning the oil filter cap proper way - counter clockwise, take note it's turned upside down)

Downtown 300 / Re: Identifying noise - Does this sound bad to You ?
« on: July 20, 2021, 07:47:40 AM »
After a long waiting time for springs & belt, vacation on island of Thassos i have changed OM contra spring with malossi spring. I have ordered 2 springs - white and yellow, only difference between the two is the stiffness. After instal i decided to keep the yellow one because that flapping noise from belt is almost completely gone with the yellow one.

The belt i have received from aliexpress is out of spec, namely the width is not specified 2.53cm but 2.7cm, so i kept the OEM. What do you guys think, can this belt still be used?

For now i'm pretty happy with the results, bike is working much more smoothly it is not jerky like before and flapping sound can be only heard when completely stopping only "tap tap" somewhat quieter for a second - not like before when it flapped any time when lowering the speed to 10-15km/h like "tap tap tap tap tap tap"

Hope this helps someone in future
