Jetting my carbs, also hinson clutch question!

[toyotaman]

Ok before I ask my questions I want to tell you guys what I have. Just so you know this will be a little long winded so bear with me please!! I have an o4 banshee that I just had some motor work done on and I was wondering if you guys could get me into the ball park jetting area Im suposed to be in.I know that every quad will be a little different but im hopping youll be able to help. I also have a question about my clutch that Ill get to later.

OK so heres what I have.

-tommey t5 pipes

-stock carbs with tors removed tommey needles and 360 main jets with 30 piolets, needles are on 3rd grove

-K&N pod filters

-cool head with 18cc domes

-timming advanced 4 degrees

-v force 3 reeds

-cylinders bored .40 over stock with wiseco pro lites

-Hot dune port done by camron at Redline racing

-Running Torco 110 octane race gas at 32:1 with Torco GP 7 two stroke oil

so theres everything done to her. I just got it started after the build and its running rich as hell. Before I had the work done I was at .30 on the bore with a mild play port and ran 340 mains. so i jumped up two main jet sizes with the more aggressive port work and the bigger bore wanting to be more safe the sorry when i started the bike. The bike is a dune bike that I run at sea leve but i am breaking it in at my house which is approx 1600 feet,(In Eagle Point,OR). My issue right now is it does not want to idle at all. my carbs are synced and I did not change any of the carb settings from where they were before, besides adding bigger. jets. the thing is really bogging off the bottom and has absolutely no low end, atleast for banshees sake. it basicly doesnt want to stay running unless you hold it at half throttle. when i had the cylinders done camron told me that i would have to do only minnor tunning changes after putting in the bigger jets. so im not getting why its running so rich on the bottom end when in theory with the more aggressive porting it should be just right at the elevation im at. so i know i have prolly lost you guys at this point and your saying what the hell is he talking about, hopfully one of you can read and understand all this bullshit. any ideas would be great

 

secondly, im running a hinson 8-plate clutch on it. im using my stock inner hub and pressure plate that havent been modified. my problem with this is the adjuster screw for the clutch is not long enough and doesnt reach the ball inside the clutch, there fore it wont dissengage. Im running on of the pancake berring kind of disengagers from cascade and i called them and they told me to buy a longer stud for it, unfortionatly i cant find one like it that is a bit longer. when I called redline and told him my issue he simply said to take out the eigth plate and run seven. i did this and from the little bit of putting ive done with it it is grabbing. the problem is by removing the eight plate from that basket it doesnt allow you to tighten the clutch springs down as far, so when the clutch is engaged its not pushed together near as hard. you guys following me? has any one had this problem with a hinson basket, i did a search and couldnt find a thing about it. any help would be great guys, thanks. :smile:

Ok well I finally got the quad running decently. realized my slides were in backwards. I also dropped my jetting down to 330 mains because it was running very rich. now i've ran into another issue. If the bike sits over night it does not want to start. the only way i was able to get it started was with a little bit of ether after about 60 kicks. i don't know what the issue is. its getting good spark. i tested the wires. but my plugs are really wet looking when im first trying to start it, almost as if its flooded. its driving me crazy. any input would be really appreciated.

are your carbs synced, dots and idle screws? choke tube/o-ring good? what's your compression?

what kind of weather you in and alt? your main should prob be about 340-350 at 0-1000` with the slightly cooler temps, and with a smaller p jet 27.5. your floats my be sticking. once you get it started do a plug chop, then check and make sure you have no air leaks after getting your floats loose and set, then sync and have a blast.
