    jetting, premixed open air box, .040 over.

    for the tors all i did was the two under the hood, so ill do the carb end as well. ok so 270 as a base line. ill get a leak tester, i dont plan on running it till i check for a air leak.

    jetting, premixed open air box, .040 over.

    well i finally figured out the electrical on the 03, (ignition source coil was weak) and went to do the break in, at first it was great just the avg blaster, then it did a classic 2 stroke run away, well i let it set thinking it could have just drained the carb, but when it fired again it ran...

    no spark! im at my wits end!

    i have the 2 wires unpluged for the key, and can the flywheel be bad and still light the light on the dash?

    StrokedTater244 Swingarms!!!!

    Doesn't look like a weld failure to me, looks like it started on the shock mount break then broke the other side

    aftermarket clutch kit?

    the factory clutch doesn't need the "spring washer" sounds like the hub boss and preasure plate aren't splined in right.

    brute force

    what compression you running? i built both a 700 prairie and 750 brute at the same time and ran 11.5:1 in both thinking the oem comp was like 9.6:1 or so just to ive them a bit more pep.. OH HELL did it give them the "pep"! the 700 was to much of a hand full after the snorkels and carb...

    another yz 125 cdi question

    a spark knock is not a detonation. pre detonation is by definition detonation before ignition by spark plug. see in a 4 stoke motor (and im sure the 2 stroke is very similar) pre detonation has to do with to much compression on a low grade fuel, perhaps a 13:1 on 93 pump gas, thats gonna pre...

    another yz 125 cdi question

    i know i dont know everything about strokes, but how will advancing the spark cause it to pre detonate? wouldnt that be called a early spark not pre detonation? ive done alot of research on the issue on 4 strokes while i was building my 350 warrior and could never find a documented case of a...

    another yz 125 cdi question

    been on for ever, never needed anything but to see the pictures lol is a .040 over wiseco, no P&P, it has a FMF full pipe on it, and a drop in K&N and rejetted. so i doubt predetination will even be close to a issue. but on this other blaster im building may be a problem.. its a ,040 over...
