figaro Posted October 27, 2011 Report Share Posted October 27, 2011 I was thinking of having my Serval block and pistons, exhaust shearer or R 2 rocket pips ceramic coated from this company. http://www.performancecoatings.com/index2.html is it worth the money and will it help or hurt the pistons if they where coated ?

Coupelx Posted October 27, 2011 Report Share Posted October 27, 2011 thermal coat the top of the piston, not ceramic coat. Quote Link to comment Share on other sites More sharing options...
figaro Posted October 27, 2011 Author Report Share Posted October 27, 2011 thermal coat the top of the piston, not ceramic coat. ok will that make a big enough difference to be worth my money ? would it make it more reliable ? Quote Link to comment Share on other sites More sharing options...

Coupelx Posted October 28, 2011 Report Share Posted October 28, 2011 ok will that make a big enough difference to be worth my money ? would it make it more reliable ? its debatable. its gaining popularity in forced indection apps in the automotive world though along with coating the piston skirts with some slick stuff.

[/quot thank you for your input. my main concern was about heat since i raid my bike in temperatures of 100f to 120f Quote Link to comment Share on other sites More sharing options...
figaro Posted October 28, 2011 Author Report Share Posted October 28, 2011 had my pipes creamic coated. its very nice where they coated in side and out and how much did it cost ? is it shiny as chrome ? Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted October 28, 2011 Report Share Posted October 28, 2011 I had the domes and piston tops coated with a thermal barrier and the skirts coated with a dry film lubercant. Quote Link to comment Share on other sites More sharing options...

jbooker82 Posted October 29, 2011 Report Share Posted October 29, 2011 Here is what happens when you put a motor together that is on the tight side. I heat cycled it a few times. Took it out for an easy ride. Put about half a tank ride time on it. Went and opened it up to do a wot 1-6 gear pass. When I let off the throttle the back tires locked up. I grabed the clutch and snapped it a few times and it broke loose. It continued to Idle just a little slower than normal. I let it idle for a little bit and took off finished my ride. No other probelms. Compression tested out at 185/185. Fast forward about 60-65 gallons of fuel. I had a cylinder nut come loose and blew a base gasket out. I shut it down at the first sign at a high lingering Idle. I took it home figure replacing a base gasket. When I tore it down I found this. The coating saved the cylinders. There whas just a tiny flake of aluminm on one cylinder. It was easly honed out. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted October 29, 2011 Report Share Posted October 29, 2011 You couldn't even feel those marks with your finger nale. It was like they were drawn on. Here is what the pistons and domes look like from the coater. I used Swan Tech out of NY. Quote Link to comment Share on other sites More sharing options...
figaro Posted October 29, 2011 Author Report Share Posted October 29, 2011 hank you jbooker82 for sharing your experience and i am checking out that website they look legit. how much did it cost to have yours done ? also why did you have such a high compression was it because of the coating in the piston and the dome ? how do i have my domes cut to accommodate the extra .002on the piston and the .002 on the dome ? i am about to buy a Serval 421cc Quote Link to comment Share on other sites More sharing options...

It was around $160 bucks for the pistons and domes. I had the TBC done on the domes, and piston head, and PC9 on the skirts. I though about sending the cylinders in to have the intake coated with a flow coating, and the ehaust ports TBC. You can seak about as much money as you want in to internal engine coatins. They do work because they are used in racing applications, and now auto mfg's are starting to use them as well. I didnt do it to make more hp. I done it to improve reliability. I had high compression because the engine is setup to run straight 110 race fuel. Quote Link to comment Share on other sites More sharing options...

I also want to do it for the reliability as it gets very hot where i ride my bike like 120f so i want my 421cc to be as cool as possible. i think i will do the same job you did but what if i also have the oversize radiator also coated would that help dissipate the heat ? so your cylinder got damaged from over compression ? how do you like the Serval ? I am getting a serval this month 421cc do you recommend anyone ? also is the top of your piston flaking coz it looks lumpy ? Quote Link to comment Share on other sites More sharing options...

I am getting a serval this month 421cc do you recommend anyone ? also is the top of your piston flaking coz it looks lumpy ? The damage was done right off the bat when the motor locked up. I then ran 70 gallons of fuel through the engine before I had a cylinder come loose and blow the base gasket out. That is what I found when I went to replace the base gasket. The problem was the cylinder bore clearance was to tight down in the bottom of the bore. I could get a feeler gauge in there but it was a snug fit. As for the stuff on the tops of the piston I think it is from running leaded race fuel. Normal lead deposits, and probably rich jetting.
