twoody Posted June 1, 2009 Report Posted June 1, 2009 Hi everyone! Im new to the atv's, I got my first banshee a yr ago. I traded even up my 95 honda shadow motorcycle for the 96 banshee last summer. I only got not even one day ride out of it and found out the top end needed rebuilt. so i went ahead and took the jugs in found out it was .030 over and i had to go to .040 over and had a light port polish done as well. i put a set of 28mm keihin pwk carbs on w/ pods and the banshee came w/ a boost bottle and pro circuit platinum pipes, also has a spacer for the reed cages. other than that everything is stock. through the winter went through and tore frame completely down and painted, actually everything has been cleaned up and painted. i just ordered the carbon boyesen super stock reeds. so hopefully ready to run this weekend. but i wanted some thoughts on this build, anything i should be concerned w/ or possibly need to look into? whats the best way to break in the motor as well? any serious thoughts and opinions appreciated.

Welcome to HQ! While it's half-way apart already, I'd strongly consider just tearing the motor down all the way and getting the crank welded and throw some new seals in it. If not, just make sure you do a leak-down test once the top end is back together. I normally just ride the bike for a few minutes (not overly hard) and let everything warm up to normal operating temp and shut the bike off til it cools. Rinse and repeat several times for the rings to seat, etc, and that's how I normally break in a new motor. Good luck with her. Also, make sure your jetting is right, or you'll be putting another top end in it in no time. You may want to look at milling the head to raise the compression some, and get an adjustable timing plate to bump your ignition timing up a few degrees. That will give you better throttle response and HP going up through the RPM. Quote
twoody Posted June 1, 2009 Author Report Posted June 1, 2009 thanks. sounds like a definate good idea to do the leak down test. you mentioned rinse, what do you mean by that? another question, i read in the manual that there are suppose to be rubber plugs on the bottom of the jugs for coolant (?) are they suppose to be there? i dont ever recall them being there when i took them off? should i put some in?

mopar1rules Posted June 1, 2009 Report Posted June 1, 2009 you will need to put those rubber plugs in the bottom of the cylinders. w/o them, you will have leaks occuring from the cylinder bases. Quote
twoody Posted June 3, 2009 Author Report Posted June 3, 2009 k, i was able to look at pics i took of my juggs when i tore it down. I did get a pic of the btm of the jugg and there are were no coolant plugs in them when i took them off. When i did ride it, there was no coolant leakage outside or inside or at least no signs of any leakage. so this isn't making any sense that they are suppose to be there or i will have a leakage problem but before i tore it down they wasn't there and no problem w/ leakage. any thoughts?

yamahaman244 Posted June 3, 2009 Report Posted June 3, 2009 Ya I bought a 87 really nice shape after one day of riding a ring fell off Quote
AKheathen Posted June 3, 2009 Report Posted June 3, 2009 it may not leak now, but it can when you're ridding, and it'll become a serous problem. can you post that pic for us to see? also, i wouldn't put the reed spacers on the jug side. just my .02, and welcome to the hq Quote

twoody Posted June 4, 2009 Author Report Posted June 4, 2009 just curious for what mods i have am i setup more on the low, mid or highs? Quote
shee4speed Posted June 4, 2009 Report Posted June 4, 2009 just curious for what mods i have am i setup more on the low, mid or highs? did you get rid of the boost bottle yet? Quote
twoody Posted June 4, 2009 Author Report Posted June 4, 2009 nope still have it, came w/ so i'm just gonna keep it Quote
AKheathen Posted June 4, 2009 Report Posted June 4, 2009 just curious for what mods i have am i setup more on the low, mid or highs? you're more in the mid, and should have some nice lowend. even better low-mid if you go +4 on the timing. Quote
twoody Posted June 5, 2009 Author Report Posted June 5, 2009 cool, thanks for all the input. im going w/ the +4 on the timing. minus the timing i should have this up and running hopefully tom. if all goes well. only rode it once since i got it, so i can't wait. Quote
