spurdy Posted June 28, 2017 Report Share Posted June 28, 2017 It was a 513 series piston wasnt it? I thought the 513s have stock pin height for stock length rod and the 795s were raised. If not disregard what i saidAh, I didn't pay attention to any of the numbers aside from the diameter. But he could use stock pin height pistons wit a spacer plate and you would be able to tell, right?

spurdy Posted June 28, 2017 Report Share Posted June 28, 2017 Other than the fact that there is a spacer plate. Lol!Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

I was thinking the same.. his all started from looking for the source of a leak. But I don't have a way to test my port I'd have to get my hands on the tool, as for the builders there's a few well known ones down here, ray and Shane from performance atv I believe, my buddy is pretty cool with Shane so I'll be calling a few builders to see who I feel would do the best job Quote Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk no doubt thats why i mentioned assuming there is no spacer plate. the problem here is we are totally guessing without detailed pics and more information. 1 Quote Link to comment Share on other sites More sharing options...
Rawnold Posted June 28, 2017 Author Report Share Posted June 28, 2017 So the piston is flush on my cylinder does not pop out like you said so I'm guessing stock. Just took off my left cylinder ( one with low compression) the right one is being a bit more troublesome to take off. Heres some pics Quote Link to comment Share on other sites More sharing options...
rubberneck Posted June 28, 2017 Report Share Posted June 28, 2017 ouch that piston is trash, i think you found the reason for your low compression lol Quote Link to comment Share on other sites More sharing options...
rubberneck Posted June 28, 2017 Report Share Posted June 28, 2017 what are the markings on the side of the rods Quote Link to comment Share on other sites More sharing options...
Rawnold Posted June 28, 2017 Author Report Share Posted June 28, 2017 2 minutes ago, rubberneck said: what are the markings on the side of the rods Yeah it didn't look too good to me. Only see an x on the left side of the rod and 28L on the other side. This is for the left piston, haven't been able to pop off the right side cylinder yet. Should I rip the motor down further to inspect? Or should I worry about contacting the shops for the cylinder & pistons first? Quote Link to comment Share on other sites More sharing options...
Rawnold Posted June 28, 2017 Author Report Share Posted June 28, 2017 Actually says 29L not 28 Thats my right side Quote Link to comment Share on other sites More sharing options...
ginger Posted June 28, 2017 Report Share Posted June 28, 2017 so a stock crank IIRC. you can prolly get away with a fresh bore and pistons. Then after reassembly, leak down test it. something had to have made it lean out. most likely an air leak. Quote Link to comment Share on other sites More sharing options...

Was told by my dad's mechanic (he's been at my house for the past couple of days watching me work on the shee) to take the cylinder and the piston to a matching shop that he knows, he said that he can do the bore by machine and also give me fresh pistons. should I give that a try before calling any other shops? Or should I entrust this only to a banshee specialist? Quote Link to comment Share on other sites More sharing options...

Not that nobody else can do it but the chamfers have to be right so as to. Or snag a ring and two strokes are more particular than four strokes since your porting doesn't exist in the cylinder walls on a four stroke.

Sent from my iPhone using Tapatalk I hear you, but what I meant was more toward type of piston brand and all that, is it very specific to banshees like they only take a specific type of piston and the mechanic either knows that or he doesn't? i guess what I'm asking is if I didn't tell a mechanic this was for a banshee.. cause he likely won't know what that is. Will he be able to do the porting & match me up with a good set of pistons? e- not that I don't trust sponsors here or nothing like that, id just rather do something locally before sending it off Edited June 28, 2017 by Rawnold Quote Link to comment Share on other sites More sharing options...
Ayesully810 Posted June 28, 2017 Report Share Posted June 28, 2017 Chances are if you dont go to a sponsor and take it some where where they dont work on banshees or know them they are gunna order u some shit namura pistons. I had a local place try and do that with a kx i just re did. Just send it to a sponsor. That way u can remove any guess work and get additional questions answered Quote Link to comment Share on other sites More sharing options...
rubberneck Posted June 28, 2017 Report Share Posted June 28, 2017 personally id go back with the forged wisecos like you had. Its always a good idea to have the pistons on hand for whoever is boring the cylinders so they can get the clearances correct. sure there are plenty of guys out there that can bore and fit pistons to your cylinders your friend might do great work we cant answer that. Like mentioned the ports need to be chamfered correctly or you will catch a ring know the guys here do it all the time and do it well.
