trumanbuckley1 Posted January 28, 2020 Report Share Posted January 28, 2020 They sell stock bore AM cylinders, I’m unsure of the type of bore though. I mean stock OEM Yamaha cyls. Not aftermarket stock bore/styleSent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

It’s hard telling what you have when you buy a used bike. 1 Quote Link to comment Share on other sites More sharing options...

Deets Posted January 28, 2020 Report Share Posted January 28, 2020 Guess I’m also just used to having plated cylinders. Banshee is the first 2 stroke I’ve had with a cast iron bore 1 Quote Link to comment Share on other sites More sharing options...
Keno Posted January 29, 2020 Report Share Posted January 29, 2020 Download Tapatalk on your phone to post pictures. Your pictures suck. Stock cylinders are not nikasil coated. WSM are not Wiseco. WSM started as a jetski aftermarket parts company. IDK about their banshee pistons, but their PWC pictons are pretty okay. Does the bore look good? 120psi is fine for a stock banshee. It could be that the head damage is from before the topend was repaired. Buy an aftermarket head with 22cc small bore domes and run premium gasoline.

DoubleJay Posted March 9, 2020 Author Report Share Posted March 9, 2020 So after 1 1/2 months and at least a $1000 bucks . She’s up and running . Just wanted to thank the guys that helped me on forum. So new Wiseco 65.25 pistons , polished intake and exhaust ports . New cool head , new clutch w billet basket , +4 timing plate . Pro design filter in stock air box. Carbs jetted w 280 main , 27.5 pilot. And a few other odds and ends . She rips pretty good . After the first set of plugs . I synced carbs . Now plugs a light brown color. Running amsoil dominator 32:1. Do I need to do this plug chop thing ??? 1 Quote Link to comment Share on other sites More sharing options...
