Hey guys,
I bought a second hand lifan 140cc engine which didnt come with a cam sprocket cover. The cam sprocket itself looks really small? The one on my genuine thumpstar pro is alot bigger, yet they both have the large sprocket cover? Check these pics and tell me what ya think? Have they put on a different cam sprocket or something?
By the way the engine is not running yet, i am waiting to pull the topend down to check the bore and head.
This has got me stumped, any help appreciated.
This is the Lifan 140cc
This is the Thumpstar 125
Just remember the cam sprocket cover is the same size?! What the?
Is this the genuine lifan sprocket? Please help ASAp!
