Thanx for all the advice, they are going to fix this mess.

@theatiss Stock pistons ceramic coated and friction reducing coating. I was in a bit of a rush to get the crank to them so never weighed it.

@gazx10 Vance and Hines did a performance valve seat job, they were never suppose to coat the valve seat as the valve seats weren't originally coated when I first received it. The head has been decked .015 if I remember correctly. Think it should be enough to raise compression with thinner head gasket.

@mpp12 I'm hoping the the ceramic wheel and transmission bearings as well as the ceramic coated main and Conrod bearings gets me close to 200hp. Another friend got his gen 3 gasflowed and cams with stock bottom end made 191 hp, a 2015 s1000rr made 182hp on the same dyno so hopefully the ceramic bearings get me the last 10hp. Just spinning the transmission by hand it spins 10 times easier.

200hp might be a bit optimistic but I'm going to try and stay positive even after al the shit that has happend. And yes I do regret sending the head to get ceramic coated. But thats just the way it goes. If I didn't do it know I would have done it 6 months down the line.

can measure easily to see how much decked. on first 4 gens those 2 small head bolt cast bosses on the head just outside the cam chain tunnell will measure very very close to .670 inch length on every one i ever ck'd. so .015 off will measure very close to .655 from top of boss to head deck surface. .015 off or not just saying those chambers are huge still. let us know how u come out.

@gazx10 Maybe I can go with a thinner gasket then .45, removing middle layer of .60 gasket should make it thinner than .45 in theory. should be enough for huge chambers. Thoughts? Piston to valve clearance will be tight so will have to degree accordingly. Kinda leaning towards sticking with the .45 gasket, as I'm not certain of chamber size with out measuring it

It is been a long time since I've been on this form, studies and work has been hectic

Managed to get the bike back together after a lot of issues...

Took it to a "reputable tuner" got the bike back idling at 2000rpm and running like ass... Decided to pull the mapping and guess what timing, ignition map is still stock with fueling all over the place. Well decided to road tune it, correcting the fueling so I can use the motorcycle for the time being as is. Motor lasted about 280km and spin a conrod bearing. Turns out oil and water pump decided to destroy themselves...

Long story short fixed it, got the bike on a reputable dyno and it made 186hp on a very hot day. 35 degree Celsius and bike temperature at 105 degree Celsius. The owner of the dyno mentioned a 2017 s1000rr makes 181 hp on the same dyno but I have not seen a dyno graph confirming this...suggesting it needs to be taken with a grain of salt. The dyno did, however, show a gain of 22hp which is a significant gain but 14hp less than the original 200hp I was hoping for. Guess I was a little naive about the gains I would get.

I'm planning on getting the bike back on the dyno to get the ignition timing tuned as there might still be some power left in it. The dyno owner mentioned that they have gotten a few more horsepowers out of these bikes adjusting the ignition timing. Sounds promising...

I'm considering supercharging the bike as it currently sits but that will only come at a later stage when I have more time. In the meantime, I managed to total my er6n. Walked away with just a badly bruised leg and light concussion. Forcing me to purchase a new daily, thus I am now a proud new owner of an Aprilia Tuono 1100RR. Loving it but the zx10r will always be the weapon of choice.

The bike does accelerate like a bat out of hell, and I have raced another zx10r, gsxr 1000 and zx14 all of which did not come close to me.
overall I'm happy with the outcome and looking forward to getting input.

P.S Still need to race BMW S1000RR and looking forward to the opportunity to do it.
