[inspectorcritic]

Ive started a project and am curious after receiveing the kit i purchased was from gasbike for 299.99. Its a 2015 model states the sticker im curious what all i should probably do before installing ive already noticed it has scratching on the piston from shotty porting and theres debris in the engine from first glance.View attachment 78501 View attachment 78502 View attachment 78503 View attachment 78504

I bought one from Gazbikes blew out 2 cylinders then the bottom.
Long 100 mile+ rides maybe I should have used a banana or better exhaust instead of stock.
But, I see here Frankenstein has risen from the dead and is walking back out of the graveyard so this is an old post 2017 you tell me how did you like your ride?
