Prox Pistons And Teflon Coating?

[streetshee]

hi there,my shees now lost a lot of power,one year old,15,000 street km,and have ordered some prox pistons because ive heard they last a bit longer on the street than wisecos,i wanted to get the vito super stocks but i need them this week and ordering from america takes too long and costs too much. my questions are,: are the proxs ok and has anyone any input on teflon coating pistons? my boss swears by it,but hes a fourstroke man and im not entirly convinced its a good idea on a 2 stroke????????? any help will be greatly appreciated,thanks.

I read somewhere about someone coating pistons with something. i think it may have been teflon. Supposed to reduce heat build up...... I think it was in an RD 400 engine though.... I am not sure.

what my boss aez iz,we first pre temper the pistons at 250-270 degrees for half an hour,let em cool,then a micro thin film is sprayed on and back in the oven same temp and timed at 40 mins.the teflon coat we use is green colour and is supposed to glide better and retain oil better,reduce friction and realy does last,ive seen pistons with tef after 3,000km,and was realy surprised about how the coat held up. what about the proxs? anyone?

I think Duncan racing uses them. Check there site or give them a call for more info.
