    Keihin PE28 Jetting for GPX155z with Big Bore and V2

    He guys, I finally bought a Keihin PE28 to go on my 155z with a V2 head and big bore kit. I've had no luck with the OKO 26mm and OKO 30mm, so here's hoping. My main question is what jetting should I go for? I've seen plenty about jetting for the 190 anima, but then again that has...

    Daytona Anima 190 F FDX FLX, Zongshen 155Z , Yinxiang YX150 YX160 Clutch Basket repair

    an engine i worked on had a lot of rubber in the oil filter strainer down the front/bottom of the r/h engine case so i thought i had better check the clutch basket. it looked ok, but when i held the alloy basket, i could move the gear on the back forwads and backwards. that shouldn't happen...

    yx 160 head on 155z

    I currently have a 2010 dpro 160 with the 155z engine (oval cam chain cover) and shes getting a bit smokey. Ive changed the rings with little or no improvement. Some have suggested valve stem seals which seems too hard for a rookie engine wizz like me so im thinking of buying a yx head (with...

    155z v2 hi comp piston failure

    Sold my old 155z v2 headed motor and lasted all of 10 mins apparently, I was told by someone there when he installed it that he used any old filthy oil out of the drained oil drum and when it went bang at top end around 12000 rpm she grenaded, not the worst ive seen but none the less it caused...

    Does a GPX Head fit on a yx160

    Hey guys, I am looking at buying a yx160 for my bro's build, and also looking at the possibilities of rebuilding it in the future with the spares I have. So in effect my question is: Will a GPX 155z/160ho Head, Cylinder & Piston, fit on a yx160 bottom end? If not, what would I have...

    crash and quick pop of the shoulder

    Took the bike for a spin again to try another jet setup in the 28mm koso, went from a 36 idle to 40 and made the bike run junk again at lower revs so ive got a 38 on the way to try, everything was good going, got nearly to the top and i dont know what happened but i think the front wheel came...

    hillclimb

    the camera doesnt show the true angle but it is quite steep and loose rocks and dirt, having a 155 with hi-comp piston and v2 also with the 1/4 turn throttle can make it quite interesting trying to wrestle it all together. <iframe width="560" height="315"...

    Cheap mods that really work thread?

    I'll go first:) When you turn the manifold around on a KLX and chop the starter boss off, you need a shorter tensioner. I use the YX/Z ones. If you are SURE you are smarter than a spring-loaded plunger, and nearly as diligent, you can either buy a $100 "billet" adjustable one, or spend 5...
