    Where Can I Find a Plenum Small Enough To Fit 32 - 36 mm Intake,

    Would A BOV Not Do The Job Then From Experience

    I Want IT Runing Around The 12 PSI Force And Drop The Compression Ratio To 7 : 1

    Finally Started striping Down The 250 To Respray And Modify Found Out It Runs A Mitsubishi Electrical System

    Il Have A Few Pictures Soon Now Its Been Moved To Our Workshop I Can Crack On

    Turbo is exhaust driven Supercharger Is engine driven but it will need some sort of pressure release system between charger and engine BOV seems to fit that purpose

    I have been on hold on this project due to unforeseen circumstance

    But went and had a look at the 250 yesterday and it should be in the bike running Stock in a month or 2

    then il start on the charger

    so the other day iv pulled me bike out jumped on rode off, I get to the end of my road and just about to join an roundabout and the engine cuts out . . . :madflame: WTF keep trying to start it nothing. pulled choke in and it start then after 15 - 20 seconds cuts out and wont start

    I keep trying nothing cant even smell petrol come through Hmm, so I bust out mini tool kit open up the carb bleed to see if the carbs getting petrol, nope no petrol id all ready checked the petrol tank when it first cut out so iv isolated it the fault to the vacuum tap to the float needle (pray it wasn't the float needle) took the petrol hose of the vacuum tap and check its operation... petrol pisses out, blow down the petrol hose to the carb nothings passing through. . . shit needle jam iv had this problem before and im not having the carb in bits again iv got somewhere to be trying to think of ways to unblock it tried taping the carb till it drops (worked previously) nothing running out of ideas here, I remembered I had a mini tyre pump in my bag worth a shot so I placed it on the hose end over the pump, 5 presses in and I here a tss come from the carb and can freely blow in to the carbs petrol hose. Fucking yes reconnected every thing and petrol starts to come out the carb bleed Yes Yes Yes I was quite literally jumping up and down, tighted up the bleed and gave it 10 seconds on the starter it lives RESULT :D

    so my quick solution if ya carb float needles jammed a tyre pump on the petrol feed hose will unblock it :D I went and grabbed some redex to clean out any shit that made it through any one else got any amazing roadside bodges

    I once whent 10 miles with only an elastic band holding my engine sprocket on, after sprocket and the retainer shot off while heading home 6am sunday morning

    best allround on/off road tyre on the market in my opinion Metzeler Unicross

    im on my 3rd set now and they are amazing

    dry or wet tarmac they have never failed me and as on/off roader tyres go

    on the dirt sand and gravel they bite the floor and away you go

    they last a good 4000 - 6000 miles on a 125 on road

    very aggressive tread pattern

    bad news is you cant get them any where as the don't produce them any more

    also for tyres I seriously suggest using

    openeo.com free delivery (2-3days) cheapest around shipped from poland

    if I can get me a set for cheap il give em a go though

    Need the electric tech guys (yamaha YBR 125) Please

    nope I think theres only one and a spare in the back of the starter solenoid holder

    and neutral is also a kill switch for when the clutch (kill switch) is engaged before starting

    find where that spark came from

    or do as I did run it on 30amp fuse that problem connection/wire will will soon start smoking then you will know which one and just trace in a new one

    ^I don't seriously suggest this^

    it was just my lazy way of finding a problem wire but it worked, its just lucky nothing else blew

    XT has died

    no there is supposed to be oil in bothsides for definite

    you can be sure of this also by the starter motor being stator side that will need oil on the gears

    whats actually wrong with it dose it start at all, any funny sounds nocking or smells burning oil or electrics, what colour is the exhaust smoke

    the only oil seal I could think that would cause it to die and still be holding oil would be the piston oil ring and is letting oil up past the piston

    that would usually be down to there being to much oil or a blocked crankcase breather

    so how many miles has it done

    do you self service

    keep on it tho mate its the worst pain seeing ya bike and not being able to ride it

    need any pointers message us

    well it seems to me that stock bikes tend to go ? into 1

    im guessing this would be to make them quite and you do lose some performance because of this pressure change

    but I suppose it depends on how you setup and if your taking weight in to account

    I think were going 2 - 2 less welding to do and less complicated abit heavyer

    if ya got a good welder and grinder to hand also got a bar bender it should not be to hard

    iv been checking on comparison but wont get quoted

    il try when its done and dyno tested or give them the stock BHP and add that its been super charged

    im not a 100% but il try anything this principle of a supercharged engine is way easyer than turboing to me and is more efficient and cooler

    but its getting it to run at the right ratio increasing RPM from head to compressor and getting it a good PSI and being well balanced which will be the hardest so the XT don't just vibrate to pieces

    gonna have to I think engines run at different RPM's and Suzuki only has a 6 pin cdi xt has 7 same block connecter though

    have the loom battery fuse board just need rec coil and cdi I can loop most the kills and the rest il use the XT's ie key ignition lights clutch switch and break switchs

    as most riders I love me first bike but knowing that I was doing me DAS test this year (Now Passed)

    I started to think what bike to get next and almost brought a 95' ZX400 that fell through

    then decided to look in to what engine I could change for my XT 125

    250 seemed a reasonable upgrade

    about a Year ago I payed for an engine for mine and a friends project which ended up going back to a 125

    That will do It came off a Suzuki GZ 250 (marauder)

    not the most powerful engine but its already double a stock XT's BHP on a heavier bike

    so iv started to buy the electrics

    came with A 34mm CV carb iv restored and boxed

    spec is a Single AC 249cc SOHC 4V Twin exhaust ports

    so it has a chance of being modified

    while sat there looking at the engine then the manual then the engine over and over

    I noticed the cam runs a duplex cam chain :) and on the head cover on the side

    there is a cap centered with the end of the cam shaft (chain side)

    im thinking damn that's strong enough and so perfectly positioned . . . SUPERCHARGER

    so il remove the cap have the cam remade with higher lift an added output shaft to run the SC system

    add a oil seal ring where the cap used to be correct to the output

    then figure out the correct RPM Ratio for the compressor to reach the correct Psi via 2 cam belt setup

    this will not be easy a lot of trial and error

    but when it works damn it will be a one of a kind

    im hoping it will take less than 3 months so progress may seem slow

    any pointers welcome and il try to keep this updated

    I get the ultimate combo on the way back from work about 7am sundays

    a woman in a black 1.8 BMW always over takes me and drives like a dick

    tempted to load up me pocket with nails and see what happens next time

    not worth me getting banged up tho

    well its an Yamaha XT125R with a Suzuki GZ 250 engine

    = YamaSuki XT 250 Z

    and theres enough room for modifying with the 250 to add some ridicules mods :)

    yeah that is a very worrying trend and not to prejudge but tend to be young female drivers in small cars

    Passed me DAS yesterday woop woop

    and nearly head the same thing happen during my test

    young woman head phones in typical

    tester must have seen I have ability to remain calm and in control these situations

    iv fixed the XT now so im gonna get working on the 250cc supercharged engine to go in

    need to make the super charger this shouldn't be to hard just need two more electrical parts

    and make new full exhausts

    naming it the YamaSuki XT250Z :D

    I will post a progress on the projects forums
