ZRT6 Performance

Does anyone have any suggestions for boosting the performance of a ZRT6?  A
friend suggested milling the heads to raise the compression and then adding
another base gasket so the pistons don't make contact with the domes.  Would
this really increase the compression?  It seems like on change cancels out
the other.  I am also considering an aftermarket head from Black Magic.  Any
suggestions are appreciated.

I found that piping my ZRT 6 really helped it out...and a gear changed was
also a big help.

Do not..I repeat..Do NOT go with the Black Magic stuff.  I have been pretty
dissapointed with the quality of their stuff I bought.  I would encourage
you to look at D&D instead.

Good luck!

Yeah, compression won't change that much... (assuming you mill off the same
amount as the thickness of the base gasket.)

This is basically a 'poor mans port job'.  It changes the port timing by raising
them all the thickness of that extra base gasket.

Some engines it works good, some it won't... :\

If you're interested, I've got a set of D&D trail pipes I'd sell, adds 18 hp.
They helped my 600 zrt.  I'm putting mine back to stock and selling it.  Also
have a set of V-force reed to sell too.

I have a machinist friend who milled the heads on his ZRT6 to raise the
compression. I can ask him how much he took off if you want to know. BTW I think
the ZRT6 is one of the few sleds that has flat top pistons.

I put set of D&D pipes and clutching on mine. I also put the Black magic head
kit with v-force reeds. Luckliy I have the dial adjust front arm shock on my
zrt600 as the front end would not stay on the ground. I also have a D&D power
breather,192 studs, I have also geared it. It takes my brothers zrt600 by 6
lengths out of the hole and keeps walking away. This year I added a set of 39.5
carbs. Kevin

I'd like to get $350 for the pipes and stinger (list $749) and $150 for the reeds,
plus shipping.   I'll be out of town for the next week.  We finally have plenty of
snow and I've got to go to Miami for the next week............    # 97-98 600ZRT
