Although you shouldn't find nearly as tight as was new, preheat before each start.

I went a tad lighter than my medium tightness both your sets. I suggest richen high + low needle setting 1/2 turn and Heatcycle 4-5 easy tanks on the track easy at half throttle max, cooling between tanks, and you should be ready to start race tune.

Hey RayA,

What would you recommend doing if the piston head has a little scuff on it? Is it worth repinching the engine, or will there still be performance issues?

My view of a "scuff" is a surface finish condition less severe than minor pitting, that which with my process improving surface finish conditions would not be operant after my servicing. Please note, we need to be on the same page here and your "scuff" I will hope is not a "chunk" in piston. None the less, ship the set to me and should your set be un serviceable at my incoming inspection I will consult with you by email. Feel free to call, text or email me with any further questions....or just post here this RCTECH thread.

Kind regards,

RayAracing

Here are a few pictures...

From the pics illustrating side piston damages there is no doubt surface finish damages of the sleeve liner. Unless the liner scratching hones out the set is garbage. You are welcome to ship the set to me to inspect further. First clean sleeve bore well yourself and decide if the scratches appear shallow or deep. Light scratching will hone out and the set will re-lap in; Deep liner scratches will NOT.

Brent,
Your package next day aired "Marked Urgent" deliverd here today, serviced and return shipped. Calculated monday delivery you in Cal. Slight blemish on side piston (2) places inspected and with light liner honing should relap in nicely. With this light-medium tight resizing go easy 6 tanks on the ground 1/2 throttle max, and should be ready to race tune. Keep me posted and good luck your race weekend coming. Call , text, or email me with any questions.

Kind regards,

RayAracing

Ray you did my 821b and fms for me about a week ago.Man that 821 came to life after 5 heat cycle's and 3 tanks.It just fricken rip's.I'll get on that fms later and let you know how that go's.You do great work at a awesome price and for that i thank you sir.You and Mark from PowerHouse are the only one's that do work for me and that's the way it going to stay

How many times can you have the same piston and sleeve re-pinched ?

Billy,
The 821b was a piece a cake, cleaned up with a 2+1/2 tenths resizing. Now the FMS is the one I need to hear about. You see the note on invoice - it requred some serious EXTRA ATTENTION with reconditioing process, before streightening out. Please keep me posted.

MadBrad,
It truely depends on the wear factor,surface finish condition,resulted geometrical sleeve-case fit, along with engine model you are refering. I always note on invoice what I see each engine model piston + sleeve set recieved and serviced. With out seeming short here, I have seen some not worthy "one" reconditining-resizing service, with other repeat customers getting 2 and even (not often) as many "three" light resizings the engines life.

Hi ray, i sent off my piston, sleeve and button for the Nova Mega .12 today.
I forgot to include a note with it asking for you to give your thoughts on the wristpin and conrod....(which i have ordered new anyway).
I't will be interesting to see how long it takes to get to you as it's my first international posting.

Cheers

Martin
