Which engine?

Gramigno · Yesterday, 06:40 PM

Hi.
I'm learning about Chinese bikes and I have many questions,

I'm locking for a 250cc, 4 strokes, chain timed ohc, single cylinder, carburetor fitted , possibly with balancing shaft, which I don't know the name for English, it's a secondary shaft that rotates in the opposite direction of the main shaft and helps diminishing the vibrations of the engine.

I would like it to be 250 because I'm an heavy fat 300pounds guy, I prefer it with carburetor cause it's more simple to adjust and repair than an EFI circuit for a normal non professional person, and I wrote on the Enduro section cause I think the only real work oriented .motorbike must be able to overcame every road condition, flooding included and if I properly understood in Panama rains very often and very violently and I can imagine sometimes the road will be a 1 foot deep river and I still will need to go through to make my delivery.

My first question is if you know if such engine exist and if it exists, in your experience which one is the most reliable?

Reading here I found out Jincheng and Zongshen are good manufactures but I'm sure you know this topic way better than I do!

Thank you very much for any answer

Cheers!

Try this one:

I ordered a 250 four valve and got screwed, so YMMV.

Just buy a PR250 or 300. If you want to get fancy buy a CB300RL.

Do not order from CQHZJ on Alibaba.

Hi, I can't order from Alibaba, I will need to go to a shop and buy it,

And I wasn't able to properly explain myself because I wasn't locking for an engine but a dual sport or adv bike which already has this kind of engine fitted on.

Recently I discovered the Zongshen 250cc models named RX and TT
On paper they seems good but because here you have a ton of experience, maybe someone already bought and used them than swapped them for a better model which I still have never heard about.

I'm trying to understand which is the most reliable and long lasting 250cc Chinese dual sport or adv bike in your experience because it will be my work tool once I'll land on Panama and start working a s a rider, and then I'll have little time to make my own opinions, that's why I'm asking to share your experience if someone already have it
