[img]i/expressions/brokenheart.gif[/img]I need Help!! My banshee was runnig bad back a month ago, I took a compression test and it was down to 70PSI on both piston,So I pulled it down, sent the jugs of to a place in L.A. that rebores and does porting,Put new Wiseco piston kit in it 25mm over to clean it up. I got it all back togather and have been fighting it for a week,got it running but starts hard cold,tryed everything no luck. I finally did another compression check on it a lord-behold, now I got 65psi on both pistons!!!! What the h-ll!!!!!!!!!!! I will have to tear it down again,they either bored it to big or the piston kit I got was for a std 64mm, This is what I am thinking!!! does this sound like whats happen to u Guys???? I B really Upset about the Whole thing. James Ps Any feed back will sure help me out. Or anybody else gots a Ideal.

 

You may want to break in the motor first, then do a compression check... The rings havn't seated yet... and use regular 2 stroke oil not syn.

 

[img]i/expressions/face-icon-small-confused.gif[/img]Thanks, I was able to get it running but not happy at all with it,it starts hard cold,once I get it warmed up it runs pretty good,I think the shop ported the jugs to much and that has dropped the compression,may get another set of jugs and start over, keep the ports stock,my understanding is the bigger you port these or OPEN the ports up it affects the compression, I just wanted a clean-up port job, and got a DRAG port job done on it.the builder says I can get the compression up with a NOSS head&chambers- but were talking a lot of money!!!! And will it be Dependable?????? and start easy?????????? I hace to pour gas in the plug-holes to start it now!!!! Thats not RITE!!!!!!!!!!!!!!!!! I have run it a few hours now and have 112psi compression,with a 35ths milled head.Thanks.
