90Bansheedude

Ive measured several times, and I keep getting 64.80mm. Is this acceptable with a light hone (no deep scratches) to drop in a set of wiseco or other (recommend brand) pistons that are for a 64.75 bore. Current pistons are toast. Maybe im being over careful, but I dont want to bore if i dont have to, but I dont want it to blow up or run like $hit either! Simple question for an experienced builder. Thanks Brian

I dont know, we have an auto shop, and none of our spring compressors worked good (they were all to big!). So i made a smaller hook attachment for them so they would kinda work, and it was a PITA, but I got them on.

I only have 91 were I am, unless i can talk the airport guy into giving me some AV gas again, its leaded fuel. So...is +4 ok on 91, and up to what comp? Also, is leaded AV gas ok to use? ( I think it might be about 110 octane.)

they aren't! They do get damaged! LOL, JK it is a pain in the ass! A proper spring compressor helps, but its not fun.

Thanks Brugal, I appreciate the suggestions!, Ya i know, I looked on the website (of course mine aren't new) and about shat myself when it said $1k for 2 shocks! (thats also why my post was so long, i was excited! :biggrin: ) It doesn't look like the stator could have moved, and its tight!, but i suppose its possible. Or they just didn't have a clue were to set it? Does this sound like a good plan? Clean the cases out fromt he melted piston, reassemble with new pistons and a hone job (cylinder measures approx 64.80), find out what compression is with the stock style head (any specs so i can check if its been milled) to see what I need to run for gas (91 is all that is at the pump, but I may be able to get leaded AV gas, is it good to use?) Put timing at +4, Change the jets in the stock carbs ( to what, i dont know yet, has k&n and bills pipes, and im in Nebraska). And it should be a decent runner. Sound good? Or should I put domes or mill the head if its not? Im going to be trail riding and some flat land playing and sand drags.

yeah, sorry about the long read. I picked it up for $260. I hate to part it out with all those nice parts though. Any idea why they would have had it at - 1 1/2 degrees?

I made a post already, but i couldn't figure out how to change the title, cause i named it cheap banshee mods, and thats not even close to what I am wanting, and i figured it would get lost because everyone wants cheap mods. I am curious what I ended up with, and what i should do. http://www.bansheehq.com/forums/index.php?...=116263&hl= Theres the link to the previous post, if it should be moved, thats fine. If I shouldn't have posted here to, I apologize, and Mods you can delete it. I just need to know what I should do! I dont want to spend alot of extra money, (keep it cheap), but with the mods it has already, I dont want to waste them by not using some of their potential. Any ideas what i should buy, or not buy? Thanks guys, i really appreciate it! Brian =)

I should probably add, that i want to go fast, but I want to make sure its reliable, and isn't going to blow up again. Im new to banshees myself (ridin them a little, but 1st to own), but Ive rebuilt a blaster (it was very nice) and I also have a 02 raptor 660, did a tranny fix for it. Its got pipes, filter, jetted, normal main stuff. I was debating throwing in a streetbike 600 or 1000cc, but then when i found the motor had all the stuff done to it, i think i changed my mind.

Its almost like opening up a treasure chest! :biggrin: Well I brought home a banshee late last night, after driving 5 1/2 hours round trip soon after i got a phone call from a guy who said he had a banshee i might be interested in. I went and checked it out, and paid the guy for it, brought it home, and tonight im just getting to tearing it down. When I got it, the head was off, and the left piston had a hole in it, and the right one had a droop in the front, but it was not locked up. So, i knew it needed a top end rebuild. he mentioned some things like it had a ricky stator, welded and trued crank, k&N filter, and a few other things, but you never know if you can believe them or not. What I do know, is it has extended chromed TIG welded A arms and J arms. J arm measures approx 13" from pivot to center of ball joint. A arm is about 15 1/2". (how much extended are they, and who made these? Denton racing maybe?, there is a Denton sticker on the plastics) It has a aftermarket axle with 2 spacers before the hubs on each side (measures 34" from inside hubs) with large hubs (about 6 1/4") warrior maybe? What brand of axle, i dunno, but its adjustable. It has Ohlins shocks up front that have adjustment screws on them with the attached reservoirs, and Im not sure what the rear is, but it looks beefy with a blue spring and a remote res that looks like it has cooling fins all around it. It also has a steering dampener on the front as well. Has a set of Bills Pipes and silencers and K&N filter with box lid on, but hollowed out the tube intake passages above the filter. Nerf bars, aluminum bumper and swingarm skidplate (left side nerf is broken pretty bad though) Wheels and tires Fronts = Dunlop 21 x 7 x 10 on ITP aluminum rims - about wore out Rears = Bandit A/T 20 x 10 x 10 on Yamaha aluminum - plenty of meat, feels like they were roasting on pavement though! :biggrin: Extra Paddles = AMS Aerospeed 20 x 11 x 10 on ITP aluminum Motor, like I said had the head removed, but there (looks stock, he said it was milled), has stainless water pump and clutch cover and the tors carb tops have been replaced (if tors was on 90s) Wiring is much to be desired and the bike has definitely been well used and rode, but frame looks good and solid. OK....now I start taking the motor off and apart to clean it out and see if i need anything else and see whats actually inside. First, I find that the cylinders have been ported (not mirror polished, but ported well) have studs, and are engraved on the side is "play 3738" (whats that mean?) and the reeds have a large reed covering both sides, then a pair of small ones on top of that, with none of the stock curved metal guards or stops on top (no idea what they are, no name)...then I take off the stator cover to find a adjustable timing plate, with I think a Ricky stator (as the guy said it had, but i gotta order a flywheel puller to get into it)...I was kinda wondering though cause timing was set at -1 1/2. negative? purpose? Then I look at the crank to see if i can see anything before its split, and its a Hot Rods 204 Crank with 121 rods! NICE!....now to take a look inside the clutch cover. Found out that something (lock washer maybe!?) came loose and made some good marks on the outside of the clutch basket, and took a small chunk out of the aluminum oil deflector that is part of the cover (i think it might be ok, clutch and cover) Take the clutch out to inspect, and the basket says JP racing on it! It has a little slop, so I think the buttons (right word? rubbery dudes underneath the back cover) could be replaced. Anyone know of JP racing, or were to get buttons? I Googled for awhile with no luck. Also I noticed, the crank kind of looks like it is a little to far towards the clutch side of the motor, but maybe its just me,...is that possible, and what would cause that? Further notes...I cleaned off the top of the cylinders a little, and I can kinda see an impression in the remaining gasket residue that says 66m?, 18cc, 12deg?...its kinda hard to make out, but I think thats what it says (it is like a mirrored image, so its bassackwards). So i am wondering if the head he took off to inspect the pistons was a cool head, chariot or something with 18cc domes, and he sold it, or a previous owner did? what do you think? The carbs I believe are stock, and the one i opened, had a 280 jet in it. Gas smells kinda good, or the oil does. (not sure if its race gas, or oil smell, my sniffers messed up right now) =) Im curious why the top end melted. Bad jetting?, they put the stock head back on?, timing -1 1/2"?, fuel octane issue?, or just running it too hard to long? Anyhow, thats the start of my story of the build, what do you think? What would have been a good price for this bike? Just curious. Ill tell you what I paid tomorrow. Also if anyone has any interesting or useful information regarding my info, I thank you in advance! Brian =)
