I need a new piston for my 185s.Options?

[StangLX302]

Well, my poor 3 wheeler has been smoking for a few months now and now it barely even runs. It's time for an over haul. I want a piston that will bump my compression up a bit. I don't mind running race gas if I had to. I can get race gas all over town here.

What are my options? Anyone make anything for maybe between 10 and 11 to 1 compression? How much can I SAFELY bore a 185s over? What is a fair price to pay for the bore job?

Go with a Wiseco 10.25:1 piston, and anly bore it enough to clean up the cyl. wall. Any more of a bore is just wasting future cyl. life.

I was just checking out Weisco web site and you basically have to use a standard sized 200s piston and bore it .080" over. Would that be OK?

Don't overbore unless the cylinder is so bad that it must be done. Have you tryed looking at Pro-X pistons yet?
I looked at the Wiseco site, and they are listing only a 200cc piston as a 185 replacement. You may have to go with just a normal comp. 185 piston, OR pick up a good 200cc jug and go that route.
Another option is to buy a Honda 200X piston rather than an aftermarket unit. I did a 200cc machine recently, and the Honda parts were cheaper!

That will just bolt on without changing anything else?
