Chinese Engine Swap? How to use stock honda exhaust on crf50 crf70 with start-up and rev sounds

Yes you can use the stock honda exhaust on a Chinese engine swap. It might not be the best performance option for the larger engine but it will work and its easy and cheap.
In this video we show you how to modify your stock honda exhaust pipe to work with a Chinese clone like a lifan 125.

Exactly the vid I was looking for! I need to use the quiet stock exhaust. How much louder is new engine? Can you use stock air box to keep intake noise down?

Hey man, trying to do the same thing you did with my crf70f, where did you buy your motor?

[@johnmoore333]

Amazon has them

[@johnmoore333]

What all did you have to buy extra my son's transmission just went on his 70 and I think it'll be cheaper to buy this motor

[@DynamoDanm]

I am going back to 420 chain and sprockets on mine and using a 420h chain. outside that it was an easy swap. You may also need a new throttle cable depending on the package you buy, some are just motor and carb others have all the doodads

[@collinwillie]

What did you do for the throttle cable?

[@randomgenius8551]

I used a cheap pitbike cable similar length. Cost $15.

Did you have to change the chain length when swapping

[@dirtybikeclinic1237]

Ellija Mitchell no I used the stock chain length.
