Hi folks,

New to here so thought I would say hello. I got myself a pretty awful $90 chinese morotized bike from banggood and I'm trying to fit it to a 18in Kona Hanana frame.I'd appreciate some advice - although I've managed to overcome some problems, I'm struggling with the chain rubbing on the rear forks. Here are some pics;

Had to 180 the cylender head - I understand this may reduce performance, but its the only way it would fit.

Had to get a Z shaped carb connector. Air filter still won't fit, but think I can 3d print one of those.

Had to use the mounting kit. This is as snug as I can get it

The main problem - The chain is going to rub on the upper part of the fork. I understand that the chain tensioner works from the bottom - can I get one on the top too to push the chain down? It only needs around 5mm more to get good clearance. Or can I position the smaller spoke closer towards the clutch?

Apologies if I've posted in the wrong place. If anyone has any good ideas, please let me know.

Thanks folks

Bligh me another Limey! :) Sorry NB, a moment of weakness.
Welcome aboard. I,my self, am a 4stroker but hopefully the smart guys will chime in soon. You need to post a photo of your engine as mounted in the bike frame to get good advice.
