Re: QS 138 70H with Gearbox

Derbi Senda sprocket seems to fit nice if you're using 420 chain. I will use 420 now in the beginning. Guess I will switch over to 520 when I find matching sprockets.

Re: QS 138 70H with Gearbox

So from what I can tell, the shaft fits a 420 chain with a JTF249 sprocket from JT Sprockets. Same sprocket for Honda 125 Grom. Does it need a retaining clip of some sort? If so, where do you find that? Or does that come with a JT249 sprocket when you order one...? ***update*** This post is full of...

Re: MH RYZ (derbi 50cc)

Shouldn't it be possible to just download new unlocked software to it? Ask ASI for unlocked software?

Re: MH RYZ (derbi 50cc)

Looks great! Could you describe the issue with the asi 8000? Isn't there a way to fix it? Sounds a bit sad to have a useless controller when its just a software thing.

Re: European Dirtbike Conversions

This is just wild guesses! One reason could be that for example in Poland university is free for everyone with permanent residence and since there is a movement away from fossil fuel, a lot of students might chose to do such projects and then continue afterwords with own projects. It could also be t...

Re: QS 138 70H with Gearbox

Please make your own thread for these questions because its not related to QS138.

Ofc will the settings be saved, otherwise would you need to program the controller everytime you dissconnect the battery and thats not resanable is it?

Re: MH RYZ (derbi 50cc)

It looks good! I didn't realize you would be able to fit the battery like that!

Have you decided which battery cell to use?

Re: MH RYZ (derbi 50cc)

I would have placed the controller where you have it in the first pictures since I would like to use the space where you have it now for batteries - but it all depends on the form of the battery. Its also a matter of getting the weight of the batteries as close to the ground as possible to get a low...

Re: 260v Dirt Bike 2021

Everything gets more expensive, why would you want to go that direction?

High Voltage motor controller for example:

Re: MH RYZ (derbi 50cc)

What kind of welder do you have? I have a cheap stick welder and when using 1.6mm electrodes I found it way easier to get a good weld. Now i got a cheap ass MIG with protection gas, havent tested it much but seems even easier to get a good weld.

Re: QS 138 70H with Gearbox

Thanks for the excellent photos!

Regarding sprocket, do you think welding two together to get a wider sprocket would be better for the shaft? I don't want to round off the splines.

Get a better removal tool!

I'm a bit jealous of your chassis, I'm building on the old Rieju Drac and have no good place for batteries.
