    Best rebuild options

    Hey everyone! so I've got an ultimate question. I have an 07 yz250f and i want to install a 13.5:1 piston in it. Is it better to replace with a OEM 08-11 piston into an 07 or to buy a wesico kit? Is it okay to put a 08 OEM piston into a 07 bike? Any modifications required? are there any cons to doing this, such as less reliability or valve life? My last question is, should i hone the cylinder or not???????? i know alot of these maybe have been answered before, but i want to see it all put together in one post. Thanks

    New ROTELLA?

    I was at walmart today and noticed ROTELLA T5 synthetic blend. I have used ROTELLA T conventional triple protection for three years and love it. Would anyone sugest using the ROTELLA t5 or t6 synthetic oil? Or should I stick to the conventional triple protection?

    2008 piston kit

    I know this has probably been answered 300 times... but i want to be able to double double check the answer. I have a 2007 yz250f, i will be doing a top end at 100 hours... I was looking at getting a 2008 top end kit for the extra compression... This is a drop in thing? right? no modding for a 2008 piston? are there any cons with using the 2008 piston kit instead of the 2007?

    Oil sight window

    I have a question about my 2007 yz250f. When I ran my bike a few weeks ago I looked at the oil window and noticed all the oil was being sucked out the window area and was circulating. Today I started the bike and just thought to look into the window and noticed that I could still see the oil while the bike was on. I was afraid oil wasn't being sucked away and pumped to the head but I unscrewed the oil pressure line check screw and it was working fine. So should I be worried? Does your bike still have oil in the window while running? Thanks Also when I checked the oil pressure check screw, I had to unscrew it quite a but to see it spew out, is it normal to have to unscrew it so much to see it spew out with oil?

    lead substitute

    this guy was amazing it what he does and he knows engines better than anyone... he said it will give motorcross bike hundreds and hundreds of life on the valves and everything around it... and that lead is a big deal in these five valve motors... he makes his valves from scratch from a metal called inconel which is wayyyyyyyyyyyy stronger than our valves as well

    lead substitute

    i heard from an amazing machinist today about lead substitute.... he makes all his valves himself and explained it to me today... Lead substitute cushions the landing of the valves on their seats and reduces wearing down of the seats... the valves don't stretch, they just wear at the head and pull up farther... lead substitute was explained to me to be amazing to put in your gas as an additive... and i really believe in this guys opinion as he can build an engine flawlessly... does anybody have thoughts on lead substitute? its 8 dollars for up to 120 gallons worth and ive read nothing but great news about it
