Blowtie316 Posted November 1, 2014 Author Report Share Posted November 1, 2014 Yeah I think your right. Silencer mounting didn't help a bit. Quote Link to comment Share on other sites More sharing options...
Blowtie316 Posted November 2, 2014 Author Report Share Posted November 2, 2014 I rode this thing all day yesterday and the more I think about it, the more I think the vibration is slower than crankshaft speed. Im going to pull the clutch cover off and check everything out. I wonder if I can get it started with the clutch basket removed to rule out the crank. I know I won't be able to kick or pull start but maybe i can get it going with a drill or something. Might be a lil sketchy.

Phelps Posted November 2, 2014 Report Share Posted November 2, 2014 check the play in the basket. the bushing maybe totally gone. Quote Link to comment Share on other sites More sharing options...
Blowtie316 Posted November 2, 2014 Author Report Share Posted November 2, 2014 Got it started up with the clutch removed by using a drill and socket on the primary drive nut. No change in the amount of vibration. I guess this thing is just going to vibrate. Sent from my SGH-T679 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
Phelps Posted November 2, 2014 Report Share Posted November 2, 2014 you can decrease vibration with ample isolators. going by your screen name i assume you're use to getting a car/truck engine balanced to where you feel little harmonics through the cab. nothing about these banshee motors are balanced. i use oem hangers for pipes, rubber isolated engine struts, engine washers etc also bar choice and they even offer dampened bar risers. if it's going to be a rider.... drag bike i just deal with it. been on bike that would make your arms and legs damn near fall asleep when everything was rigid mounted.

Blowtie316 Posted November 2, 2014 Author Report Share Posted November 2, 2014 Im not worried about felt vibration. Im just worried that it will rattle itself apart. It shakes plastic and makes the handlebars blurry. I get that its going to vibrate, this just seems excessive. Is it going to be worse with a serval top end and cpi inframes?

sleeper06 Posted November 2, 2014 Report Share Posted November 2, 2014 Did you ever check the pressed in motor mints in the case itself I have seen my fare share of issues with them Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted November 2, 2014 Report Share Posted November 2, 2014 They are very rigid when new if you can push them around with your finger they are too worn Quote Link to comment Share on other sites More sharing options...
Blowtie316 Posted November 3, 2014 Author Report Share Posted November 3, 2014 No I haven't checked them. I honestly cant see how they would increase felt vibration when they're worn unless the engine iss moving so much it rubs metal to metal somewhere which isn't happening. The engine itself vibrates much harder than what I feel in the pegs and bars. If I put my foot on the clutch cover it shakes the shit out of it.

sleeper06 Posted November 3, 2014 Report Share Posted November 3, 2014 Seems like you have tried everything else but what I said. And yes you would feel it if it's worn . I'm not someone who has one banshee and seen it on my friends bike or heard about it. I have built 100s of banshee motors and done my fair share of chassis work. I don't see them go often but when they do they feel like what your explaining last yr I built around 30 motors , one had bad dampners , it's not all that common but does happen. In my mind I don't how you can't understand how they would effect felt vibration , Quote Link to comment Share on other sites More sharing options...
n2otoofast4u Posted November 3, 2014 Report Share Posted November 3, 2014 My vote is that the crank is out of time slightly..... Ive experienced this before and it will make it vibrate harder than skeeters ex ol ladys dildo! 1 Quote Link to comment Share on other sites More sharing options...
registered user Posted November 4, 2014 Report Share Posted November 4, 2014 does your gear shifter vibrate alot ? mine does. hands also get tingly after a while. ive determined the crank bearings have a couple thousands slop also, so i suspect this is mostly the root cause. although i doubt these engines are very smooth even with everything in perfect working order Quote Link to comment Share on other sites More sharing options...

At this time, I am not worried about how much vibration could be transmitted to the chassis through weak isolators. I am trying to determine if the vibration I have is normal or excessive. As it is now, it doesn't seem like it would last very long. Quote Link to comment Share on other sites More sharing options...

Ive experienced this before and it will make it vibrate harder than skeeters ex ol ladys dildo! I'm going to check runout again on both sides of the crank. Is there a way to check for time with it installed? Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted November 4, 2014 Report Share Posted November 4, 2014 Degree wheel and a top dead center guage, and I'm not trying to be a dick! Just some insight. It's hard to get true runout with crank installed in all the areas needed to eliminate crank problems. With it out and in a true stand you can check the inner bearings which is where I see most runout issues on stock cranks Quote Link to comment Share on other sites More sharing options...
