KickStartMyHeart Posted September 23, 2009 Report Share Posted September 23, 2009 Ok, so here goes nothing. I am super anal about my banshee and any noise out of the ordinary I immediatley diagnose and fix. Ok, so here is what I have some questions on. I have an '01 and I just rebuilt the top-end two weeks ago. Prior to the rebuild, I ran a compression test and had 60 lbs of pressure in each cylinder. I bored the cylinders .030 and put Wiseco pistons in it. So I ran a compression test yesterday after riding it at sandfest all weekend and I have 130 lbs of pressure in each cylinder. I assumed I would have at least 140 -150 lbs of pressure after a fresh top end rebuild. If anyone has any input, please share. What is stock pressure in each cylinder?. Ok, so on to the next question. I started it and ran it for a while yesterday after putting my dirt tires back on. I noticed a chattering noise coming from my clutch area. Its not the kickstarter either. I know the dunes are hard on clutches, so I might be in need of a new clutch. Has anyone else heard a chattering noise like this? and what did you do about it? If I tear apart, I'm gonna replace the entire clutch with a hinson basket and new metals and front and rear plates with heavy duty springs. The clutch currently in the bike is a stock clutch. Keep in mind, it is an '01. I'm just curious as if what I'm hearing is normal and if I'm freaking out over a little clutch basket chatter? Thanks guys for all the input, Like I said earlier, I'm a worry'er and I would rather spend the money now than get out riding and F the thing up worse and sit with a sad face.

Paul M Posted September 23, 2009 Report Share Posted September 23, 2009 IMO you should have more compression ! when you did your comp check were you holding the throttle wide open ? and clutch chatter is not normal pull the cover and take a look. and I believe stock comp is 145 someone please correct me if i am wrong as i would like to know to .

When I did the compression test the engine was cold and yes I had the throttle wide open. The Wiseco pistons are forged pistons therefore they swell a little bit when they warm up, that could have been the reason for only 130 lbs. of pressure????

Coupelx Posted September 23, 2009 Report Share Posted September 23, 2009 clutch chatter is when the clutch kinda 'shakes' and possibly makes noise when being released. mine did this when i broke a couple friction plates. in a car with a multi-puck clutch its normal.

KickStartMyHeart Posted September 23, 2009 Author Report Share Posted September 23, 2009 Well, I just got off the phone with the dealership where I keep it and they're gonna check it out 2day. I never noticed it before I went to the sand dunes. I know the sand dunes are hard on clutches because ya gotta slip the clutch a lot more 2 get it to move. As for the cylinder pressure, I am going to get the engine to operating temp and then do a compression test tonight and see what it shows up as.

KickStartMyHeart Posted September 23, 2009 Author Report Share Posted September 23, 2009 My banshee is a bastard child...lol!! I put all new front suspension on it, top end, chain and sprockets, new clutch and other crap. I enjoy messing with it, but damn I wish it would just run solid. The sand def played a tole on my clutch and now I'm looking for a hinson basket to solve all my problems. Quote Link to comment Share on other sites More sharing options...
shee4speed Posted September 23, 2009 Report Share Posted September 23, 2009 are you running a stock head?if so,your comp.is just fine. Quote Link to comment Share on other sites More sharing options...
KickStartMyHeart Posted September 23, 2009 Author Report Share Posted September 23, 2009 are you running a stock head?if so,your comp.is just fine. Yes, I have a stock head. I was just under the impression that a new top end would boost my compression up to around 140-150. What is a stock banshee compression? I want more HP from it after riding it this weekend. I rode my friends 100 hp banshee and WOW!...that was just sickening! I really would like to get a set of CPI drag pipes, but then I gotta re-jett it and other stuff.

shee4speed Posted September 23, 2009 Report Share Posted September 23, 2009 stock comp.is between 125 and 130.You really need to port and cut your head or pickup a coolhead.Call HJR and get some ideas on how much you want to spend.I didn't see what pipes you currently are running.If you go with CPI's,you need to port for them.I like Shearers.

shee4speed Posted September 23, 2009 Report Share Posted September 23, 2009 if you want to make power,you need to port.Yes you will need to port for shearers.You can still run stock carbs with port work and haul ass.But bigger carbs are also kinda necessary.

Paul M Posted September 23, 2009 Report Share Posted September 23, 2009 Ok so the stock comp should be about 125 130 ! I wasnt sure. and yeah porting the cyl and milling the head will give you a very nice boost! Quote Link to comment Share on other sites More sharing options...
KickStartMyHeart Posted September 23, 2009 Author Report Share Posted September 23, 2009 Now I don''t want nothing totally radical.
