But wouldnt it have dried or dissipated by now? I can wash again and reapply less oil ...2 months approximately that i cleaned and oiled......it runs beautiful without filters ....but once i put them on starts spitting and backfiring at high rpms....probably need to go size down on my main.....

Appreciate ur response jereme...and yes ur correct actual head terminology on 2 stroke is basically lamest term a cap ..top holding ur plugs and cooling passage.........no ports to polish........👍 but going back to my baybay today imma pick it up from surgeon , he mentioned my air pods are restricting flow....without filters runs titts but with the individual air pods seems to choke a lil.....they are not k&n brand , just that style..before sending my quad to shop i degreased them and applied oil..close to month and a half ago.....so imma be on hunt for some good flowing air filter set up...

And "milling" or also known shaving is a procedure to remove material either on surface of head or engine block deck where they both meet to increase cylinder compression or correct warped issues "if still in tolerance."...and NO this procedure is not only a 2 stroke thing it can also be PERFORMED in 4 stroke engine aswell to increase cylinder compression...as of 160 psi. I did ask the builder to get max psi to run pump gas...he claimed 160 is max on pump gas ,setting timing at zero.......i have to trust him on that cause thats above my paygrade..the info i come across online im right at the edge but just in case i do detonate ill start looking for a good know octane booster or higher octance gas around this area..i just told him what i wanted, how i rode, gas i used, and to max head job.....

Thanks for ur response jereme, but Correct me if im wrong. 2 stroke might not have "valves nor cams" but it does have "ports" like any other 4 stroke engine........ Cylinder has an intake opening "port" where it sucks fresh air and opposite side u can find the exhaust "port" that spits out burnt gas.....so 2 stroke engines "ports" can definitely be ported( enlarged) for more volume flow and (polished )for increase velocity flow..... Correct me if im wrong....im no mechanic, but im youtube certified....hehehe

What? Ur from la area??or atleast clise by??..im down once my babay comes out of surgery

Wont let me upload images....too large file...

So update!! Anyone interested in my issue........its been with quad doctor " mehcaik" and found couple issues....he rejetted my mains from 310 to 280 and had an vacuum leak from top cover like i had mentioned... no more sputtering and engine sounded responsive but in test drive it would just wind up and no power. He took initiative to remove side cover to inspect clutches and upon removing cover found bolt head, and alot of metal debri, suspecting only clutches , he removed clutch carrier and found carrier was welded and clutches just fell apart...found where that head bolt came from and a clip from shaft was came off and damaged it unabling to secure the clip....he has a donor banshee that was gonna swap the clutches only but looks like im getting the shaft with damaged clip holder, carrier, and clutches. ..he ensures me it will work but if not he put on new parts with no extra labor ..just whatever parts cost.. ...i have a frankenstein bansheeee..buwahaha..hey as long it works...and saves me money ..its a win win situation for both...🤞🤞🤞🤞

Yoooo..now im here trying to suggest things..hahaha sounds like pretty much ur studs are junk even if u get them off, possibly too much rust or whatever...but in my case i would accept my studs and nuts are goners...i would try tightening nuts if grabs thread so they can break off or if theres no thread to grip to weld nut to stud and make sure u protect ur wheel just in case u knick ur wheel while tacking it....and same procedure try tightening to break off stud and continue to replacing studs if available or whole hub.......just an idea??

I have not checked everything unfortunately theres couple things to try but that single day i had it was happy cause i was taking her home and riding following day but it didn't ride good enough to rip her in trails so i just checked whatever was simple and in reach......and was mentioning to the local mechanic about my issue and wanted to see if he could get it running for my ride but unfortunately he didn't..."well havent heard from him" it was turkey weekend so didnt want to bug him.......but ill call him later on today..to see if he worked on it or what he found...i have a game plan that i wish to see what i find.....want to swap cdi box, with another banshee i have here, compare stator resistance which i also found some specs online, and read plugs, and also possibly swap flywheel or atleast see how it looks like....i honestly dont have much faith he will get it going...lol..the gasket i found was missing was when i was checking to see if previous mechanic swapped the slides left to right or installing backwards...lil bottom arc has to be facing the rear....and thats when i removed top carb cover to see the slides off carb i saw bare metal..no gaskets on both tops...... Rubber boots good, andfloat bowl is good too...thanks again pk31!! Appreciate ur interest and help!!.im always the reader not much of starting topics.

Fyi...I have also swapped , coil with wires and boots from known good banshheee with same results before sending it to mechanic. I can actually swap module too.....but didnt think that would do anything since either it will run or not if bad module...

Turkey weekend went out riding to El Mirage without my babay that was left behind in a local mechanic shop. It was truly missed😔. Throughout the first night i couldn't sleep just thinking about my sheeee..and the revelation i had throughout the night i remember seeing the top carburetor covers without a gaskets......could that be it ?? Leaky carbs?? Sucking air through the top cover??? I dont have have shee with me so cant not even try , test, or even comfort her....will get sheee by monday or tuesday regardless....mechanic "not the one that did the work" wanted to take a stab at it since i was going crazy trying to get it ready for turkey weekend and was over it..now im ready to to start checking stuff

Tors are removed, with stock crank....

Good read on that article.......obviously my carbs are clean and according to dyno shop that machined my heads adviced on this jetting size and needle position. And due to fact they were going back and forth repair shop and machine shop mentioned it could possibly have an ignition issue....dyno/machine shop was sure jetting not an issue so putting on dyno and fine jetting wouldn't help.......

I forgot to mention, it fires up first kick, once warmed up it revs up without a hiccup, sooo purtey , but once i get it going it sputters like mention and lack of power......its not as bad as it falling on its face , or stalling. Its just a good enough cruiser to chase around the 80cc quads that are swarming around camp.

Originally purchased quad with single carb set up and after riding year and a half i decided to put dual carb back into it....i had checked cylinder compression on both cylinders and measured 100 psi. Quad was running ok just felt like it was missing that extra grunt from dual carbs....so took it to local shop to get top end freshened up and install 26mm mikuni carbs back on. But after completion quad has not rode like it should....after going back and forth with shop i decided to bring it home....and take a stab at it and possibly try another shop since im not banshee worthy yet...i have only rode quad down my residential street and sputters, back fires and lacks power Mid to full throttle or probably all range...this shop works with a dyno tuning/machine shop that got my heads port and polished with MX HEAD MOD that recommended certain jets. Got thrown in wiseco piston 66.5 mm , bore and honed cylinder, and ended with 160 cylinder compression on both sides. Jet kit 310 main, 30 pilot, ct needle in 3rd position. Have removed air box , and rocking DUAL k&N filter pods, t5 pipes, timing set at zero "0" , running pump gas 91, oil mixture 32:1, my home elevation is 70 BUT i do most of my riding 1000 ft above elevation. Any suggestions?? Im somewhat mechanically inclined , so i can probably adjust a thing or two....am i missing any additional info needed??please..felt more power with single set up and tired top end....
