  1. I’m building a new motor: 

    t5’s 

    4mm long rod crank 

    68mm bore 

    hjr mx hardcore port w/ case match

    vforce 4 reeds 

    cool head 24cc milled domes   Since I’m trying to run pump gas 

    and 36mm pwk air strikers 

    3000ft


    was wondering what Jets I need to run just to be in the ball park  Im used to the mikuni jet sizes   The only needles I have  are what is stock in the carbs and also what bp racing supplied me with  Im sure those needles are fine  all the gave me was two differnt main Jets and no pilots (and they call that a jet kit) what Jets should I order  thanks in advance 

    also, if I Plan to swap out the domes and run race gas would that change my jetting ? 

     

  2. Alright so my 97 shee just got dune ported by redline, I put it all back together did a leak down fixed a minor leak around the boot and when I did the compression test the cylinders only kicked out 120 and I believe it’s supposed to be somewhere around 150. I have 

    21cc domes 

    toomey t5’s 

    300 ft Above sea level

    no air box

    redline racing dune port and fresh hone  

  3. Just got the juggs in about three days ago, yesterday I put everything back together I had already sealed up the cases since the welded crank got here a while ago. Got it all leaked down (had some minor leaks from both intakes used yamabond and got them sealed up) 
     

    now I need some help with the jetting 

    300 ft 

    75 degrees 

    Toomey t5’s 

    pods 

    redline dune port 

    21cc domes 

    +4 timing 

    Stock carb, Jets I have in now are 320 main, 27.5 pilot, toomey needles at 2nd clip from pointed end.  Feels boggy at the low end. Hits band super hard tho but takes time to build up in rpm. What should I change for that bottom end slugg pilots or needle clip position. Also should I plug chop that main to make sure it’s perfect first or try to figure out the bottom end bog?

  4. I sent my cylinders to redline they got the package but I rember when I spoke on the phone with them they said that they’re really backed up right now since everyone is working on there stuff right now with the Rona going on with that being said not sure who’s doing the cylinders yet And my crank is being trued and welded by Kevin Herr since he’s closer to home. When cracking the cases I found that one of the plates In the clutch stack was showing a lot of wear so I ordered the driveline clutch kit my basket and inner hub had no signs of pitting everything else looked pretty good with my untrained eye haha but I also ordered a clymers just to go through it all since I’m already here.

    Woulda been best off sending complete engine to him. Unbox when finish, install, done. 

    Yeah but all that extra labor for shit I can do we’re in quarantine so I got more time then ever. I have a buddy who is a pretty awesome welder and isn’t welding a crank just a couple tig  welds ? Ima see how simple it is and if not I’ll just ship it out I already got to removing the engine now it’s me and south Texas for the next hour or so haha

    30 pilot, 320 main to start, put the clip on the needle closest to the tip.

    should be super rich with that, Buy 27.5 pilot, 270-340 mains, and a toomey needle (or equivalent) Oh and 2 or 3 set of bowl gaskets and the allen cap screw bowl fastener sets (you will thank me later)

     

     

    Oh and buy 20-30 plugs so you can do plug chops after every tuning change to verify where it is at.

    My 98 had a dune port with 21cc domed cool head, vf2 reeds, fmf pipes, dyna ignition, stock timing and stock tors deleted carbs. In glamis it liked 27.5 pilots and 280 mains.

    Wifes 96 is stock port, cool head with 21 cc domes, boysen reeds, toomey piped, stock carbs and likes 27.5 pilot and 270 mains....

    I spent so much money on plugs I would have though I had stock in NGK...

    each bike is different.

    Yeah as of now I have from 240-350 mains and 25-30 pilots    Just got My Toomey needles bout a month ago    But I do need to order those bowl screws ur right there a pain always striping   And yeah I need more spark plugs only have about 6 sets left   I JUST got the jetting right but I want a little more power   

    were u running an air box on those two bikes? Jetting sounded lean to me. My bike has always liked the leaner side of things people say got 290-300 and shee like 280 main 25 pilot and second to leanest needle setting plug chops come out perfect tho. Thanks man that’s a lotta of information that’s gunna help me now I just gatta choose between FAST,   Her juggs or  redline 

  7. Stock head but I was planning on getting a cool head anyways   Right now stock carbs but I also have a set of 34mm flat slides those are probably to big   Based off the information you guys are giving me I would lean more towards a play port. Because I do more trails and messing around but when people are running drags I like to hop in the mix. What would u guys suggest is best for my riding style ?
