I don't know much about spark plugs. My friend seats his yzf 450 dirt bike with factory jetting. When ruining standard copper plug, it runs fine. But when he installs an iridium plug, the engine goes lean and wants more jet. What do you think? And is there a reason you don't see iridium plugs in mos...

I don't need extra oil clearance, I need to tighten things up from std. On both rods and mains. Does anyone make race series rod and main bearings for this?

Take plug out on back of block then the surprise is in there. That part is already done. Obviously, lol. The gear has been unbolted. On both sides. Yet the jackshaft still only pulls out about 3/4" before I hear a dull thud and it stops moving. Wear else can possibly hold it in? Everything is ...

Stock bottom end 302, w tw 170 runner heads. Older version. NOT the 11r. Ok. We are bowl blending the heads, and doing a valve job. General touch up work and trying to make the heads as good as they can be without making them too large. Somewhere around 270cfm to 280cfm at .600 is the goal. The engi...

10.32@131mph is nothing to be ashamed of. I would love to get my 355 to run a number like that, that's a great time. Mark's stuff just runs well becuase he take the time to research a good combo out. Have to give credit where credit is due. Im telling you.....I pour over his posts just looking for ...
