I'm am going to be listed stock cylinders and stop pistons 65mm bore. I have too many spares and want to free up space. if interested contact me or look here for them FS.

I buy a lot of hardware from McMaster car. You can get nuts and bolts and washer in different hardness's and normally they are a lot cheaper for a pack of 50 then a few OEM persay.

I ordered the jets today as the Yamaha dealer by my work which is 30 miles from home had nothing larger then a 220 mains. I guess todays 4 strokes and all the FI bikes this jetting at dealers this carb shit is a dying thing. I got the 30 pilots and 280 mains. If the temps do not hold I will be out of commission with this until spring. I normally ride in temps down to 45 degrees and up to 90 degrees, much more then that wen you get wet makes your feet cold all day long. I had bought all new gaskets and OEM air boots with all OEM clamps and clips. I'd think there is no air leak, however I can not preform that lead down test as I do not have those tools. I think the half assed shop threw it together and collected some cash before they close the doors for good. I can try other plugs but this is what came with the bike and what the shop also said to run. I noticed a few online threads about running the same plugs so only thing I can do is try the ES plugs and see if results are different when I get the jetting closer to the ball park. It's not dusty where I ride. If you do donuts for 30 mins in 1 spot then it will be but if you running up a hill and off to another one there is little dust and its all behind you. summer months are not even bad. It's not like a dry MX track in September where I ride...your lucky to see 5 guys out everyday. Attached below are the photos of the plugs I got 2 hours on with 25 pilots and 310 mains per what JR's cycle shop did. Thank you for all the help so far. In a few days I will post any update results.

YFZ shocks are harder and for MX, you will just beat yourself up. A correct pair of shock for the bike will work good. A guy up the street did some YFZ shock mod and his bike sat all kinda funky. Alba arms are not very strong, they are made very cheap honestly. I'd run stock arms before I ran their arms.

Thank you for all your help. I will swing by the dealer tomorrow. I do not trust eBay single jets.

Thank you sir. Should I buy a a certain brand or a kit light dyno jet or fmf or just swing by my Yamaha dealer by my work and grab some?

Black and red was the project bike. Blue and white is the result after I fixed it up. OK guys here are the jetting specs. 25 pilot 310 main AF screw 1.5 turns out from seated position BR8EG plugs FMF full fatty exhaust open air box lid EHS screened and prodesign foam filter No reed spacers or boost bottle Anyone seem something not right? my pilot should be larger and my main should be lower. Per FMF jetting specs. This shop hosed me...and today I find out when i went back to tell them about the issue they are going out of buz by thanks giving...wow total crap. Thanks in advance.

Once I am back close to the bike I can tell what jets are in it. I noticed the shop didn't write down on my receipt what they put in it. The bike is in a shed right now and I am 30 miles from it. I can try to get those jet sizes tonight perhaps. Plugs are NKG BR8EG Pilot Jet (TBD) Main Jet (TBD) Exhaust full FMF fatty Open air box lid with foam filter and no snorkel. No reed spacers or boost bottle. FMF states 30 pilot and 260 main for the mods I have. I'll let you guys know in a few days, hopefully tonight or tomorrow. Not having my garage due to renting while house in being built really hurts garage time. Gave as much info as I can right now. Thanks.

Was not sure what to expect out of the banshee but this one is not scaring me as most guys have told me. I may be spoiled by my YZ426f but I still like my 84 KX125 over that bike. I like riding in the power band for 2 strokes. As I said I rebuild it from the ground up, so anything messed up got thrown out or sold off. I bought a titled frame and swaped everything over also. has shocks rebuild, all new brake stuff, anti vibe stems bars, axle wheels tires swinger..the works. I wanted it build for what I did the right why the 1st time. Please do not flame the cost I have in the bike. I just am looking for help on why its not running properly. I build most of my bikes to keep so they are ground up redo's Thanks for any help.

Eastcostatv is a joke...I do not like them guys. The shop I used JR's Cycle Shop in Ephrata. The elevation change was not much if any. The hills I go to are not high up in coal country. I ride between Williamstown PA and Tremont PA and are at the bottom of the mountains vallys. The issue I wonder about more is why I ran lets say good for 2 hours then fire it up and it dies after revving...then seems to bog trying to get into power band. I'd hope a reed didn't shit the bed also. I ordered new plugs a 4 pack since my local autozone wanted $20 for 2....I'm not close to any ATV shops. I only bought the banshee to climb hills my 1985 atc250r couldn't. But a bunch of guys may of hyped them up for me to buy one not sure. Never owned one before but its a comfortable bike. Basically I have $6,000 into my bike and if a few simple tricks are not gonna help me I'd rather not pour too much more into it since the bike is 100% new from bolts to everything. Getting burned on that receipt of bad of topend rebuild didn't help my cause

I had a receipt for an OEM $250 stator. They refused to buy anything off eBay for their bikes. I can not work on the bike until Saturday do to having no light in a shed or power since I am still not in my new home yet so I can post information after I rip into the carbs. Thanks for the fast reply's. I was hoping this thing would have power like my YZ426f...I'm sort of let down at this point but it rides perfect for what I built it to do.

Recently this year I bought a 98 banshee since I have always wanted once. Had receipts of a top end rebuild so I figured it was done right. Got it home ripped bike to the frame redid it. Found many issues but expected that from a $1800 banshee. Inspected the top end found 80 over cylinders with fresh deep wear lines on side where someone reused old wrist pins...they backed out and ate up cylinders YAY rebuild a rebuilt motor. Lots of money later and due to moving (build a new home) I ran the completed banshee up the road to a MX race shop. I had no place to work on it at this point so rather then wait 5 months figured lets get it done right the 1st time. I removed all the torrs stuff. I removed all the torrs wiring also, also removed all head lights, no switch key stuff...basically I stripped the wiring harness down to like a 2 stroke dirt bike, just kick it and go. I followed the wiring diagram I found on this site and crimped all wires also. OK so after all of this shop said stator was giving random spark. Got a new one, fixed issues. They jetted the bike to my light mods. Full FMF fatty pipe repacked Stock Bore Rebuild carb Stock reeds (I think but kind of looks like Boysens) Pro Design billet foam air filter assembly, oiled the filter with maxima oil (I ride coal hills so will never used K&N in this dust) EHS open air box lid with screen and snorkel removed with EHS screen. This is my 1st banshee not my 100th 2 stroke it seems. I got it back from the shop ran good, fired up 2-3 kicks. Loaded it up in the truck drove 30 miles home (since I moved) Unloaded it went to ride...dead, no spark. Kill switch shit the bed. Removed that fired up ran good. Yesterday I took it to the coal hills. Fired it up 2nd kick with choke on, took it odd and slowly revved motor about 1/4 throttle until both pipes were warm, normally do this about 3 mins or so until I can feel heat thru my gloves. Road a 1/2 mile lap to get it all warmed up and then went to play. road 2 hours felt like it didn't have full blown top end power like it faded off after 3/4. Chalked it up to 13T front sprocket (down a tooth from 14T (oem 41T rear) and heavy mud lite 20x11-9 tires. Ate my sub, fired bike up started 1st kick and revved the motor...it went blaaaaaaaaaaaa and died. Instantly thought well shouldn't of fouled plugs out. Removed plugs...pretty black, blacker then normal milk chocolate brown I like to see the electrode. (it's 60 degrees mind you) Put in a set of plugs I had new. Fired up and went to ride after warmed up. Went across the road over to some hills went to shift into 2nd to get into the power band and now its loosing powe wanting to die...running horrible. Back down to 1st runs good, 2nd same issue, tried revving it to 3rd same stuff. Back to truck, pull plugs...black fouled our about done. Didn't ride in any water after lunch, no settings moved from original marked positing's I placed on the carbs. I am running 93 fuel with maxima premix oil @ 40:1 I do not know what jets the MX shop put in. I guess I have to redo all their work but I know the needle is at the middle clip. This is all I can provide at this time. Hopefully this is jetting related. This is not a beat banshee either...adult owned 32yo coal hill rider. Thanks in advance sorry its long, figured you should have full story.
