Long story short I tested a good handful of valve springs and found the exhaust valve spring for the 2013-2015 ZX6r fit and I can shim them up to about 46-48psi. Stock is 22-24psi so this should be a good upgrade for valve springs.

I just got the new set of zx6r springs in on Friday but was on vacation for the weekend. I'll be getting my springs tomorrow or tuesday but I'll be getting the head ready to be swapped over. I am hoping by the end of this week or into next week I can have the bike up and running with the spare motor with stiff springs and see if this will help.

Will keep all posted when I get some results in.

If the springs don't work I'm most likely going to quit this project, just out of time and money with it

Wait...what?

garth285 · May 14th, 2015, 12:13 PM

Progress:

Cylinder head off the spare engine all set up with the 13-15 ZX6r exhaust springs on intake and exhaust. 2 shims on the intake for 46psi of seat pressure and 1 shim on the exhaust side for 38psi of seat pressure.

Just have to find the time to swap the heads over and try it out, I think I might be able to get the head off in the frame so I don't have to pull the motor, or well at least thats the plan!

Will keep all updated as usual

The wife let me clean the parts in the kitchen sink:

Parts laid out ready to be installed:

Valve/Springs installed:

Adjusted the valve clearance:

mgentz · May 14th, 2015, 01:08 PM

The head can come off in the frame. I've done it many times.

choneofakind · May 14th, 2015, 04:34 PM

^^yepp yepp. Done it on a pregen too.

garth285 · May 14th, 2015, 04:53 PM

Thanks guys, I figured I could do so, was not sure if any of the cam chain guides would be a pain or not.

Hopefully I can get this head swapped out and give it a go again soon!

Ahhh progress, looks really good. You realise if this fixes your issues I'll be working day and night to get mine tuned and post some figures.

Lol get on it! Your turbo setup looks way cleaner than mine! I'm still worried maybe it's the headers I have made up but we'll see shortly!

Somchai · May 15th, 2015, 07:06 AM

Hi Shawn,

good to hear your still on your way, I'm confident you'll do it.

Good luck

garth285 · May 15th, 2015, 11:10 AM

Well heres some icing for the cake, pulled the head off the motor and found what appears to be a pushed head gasket, soooooo I may have gone threw the valve spring trouble for nothing possibly. I am going to yank the rest of the motor out of the frame and swap in the spare engine since I know the gasket wasn't pushed on that bike. Wish I had the time and money to put in some 10mm studs but thats not happening.

I think boosted your going to need a solution for the head gasket failure.

I agree. I found stud info a while back, I think the best thing would be to drill the cases to accept 10mm studs, you can get a good amount more of torque on those stud nuts vs 8mm studs. Not only that ARP makes a set of 10mm studs that will work perfect for the 250.

The spare motor with the fresh head and gasket is on the bench ready to go into the frame. Stock tq is 23lbs on the 8mm head bolts. I went in increments of 5lbs up to 30lbs total. maybe a little extra pressure will keep the head gasket in place.

Old motor is two bolts being pulled away from being out and then I'll have to throw the spare in there.

Now if this goes well and the bike is running good but I have head gasket problems down the road I'm going to probably do the 10mm studs but for now I'll see how this goes!

garth285 · May 24th, 2015, 09:52 AM

Engine is in, just finding the time here and there to work on it.
Don't judge for the mess lol...

garth285 · June 5th, 2015, 12:11 PM

Well the bike rode somewhat good, until I revved it once a little and now I have a sweet top end noise.

Going to part this bitch out, done and over it. I need to buy a house soon and need to free up money.

Lol. I think most of us are in the same boat!

I would love to take on your build Shawn if only I had the moolas and time

swarfman64 · June 5th, 2015, 04:07 PM

Hate it when life gets on tha way of a fun project!
I love the concept of turbo 250 but it's not that
Cost effective per HP when your doing all the development.
I've spent way more than a used 600, possibly two and
still may fail at the dyno. If you really do part it out I hope you
get good money for your bits.

No, am running a stock one. I don't think it jumped a tooth as it still ran right, it may have spin a shim or could be worse.

The motor thats in the bike I'm going to pull and inspect the top end, I'll put the stock springs in the head and make sure the motor is sound and will be selling it, same with the other motor.

So if anyone needs a 250 motor let me know as I'll have 2 for sale.

garth285 · June 6th, 2015, 10:33 AM

Yeah sorry guys, I just can't keep working on this project, its been going on to long and fighting me to much, now with a 2nd baby on the way I'm going to be out of time even more.

cuong-nutz · June 6th, 2015, 11:50 AM

Would the setup fit behind the stock fairings?

garth285 · June 6th, 2015, 01:05 PM

The charge pipe will probably hit the right fairing but you could probably get away with a spacer. I have yet to have all the bodywork fabbed up.

Speaking of which if anyone needs race fairing let me know!

how 'bout selling me your valve springs ?
check your inbox please Shawn...

ps. I am really sorry you have to give up on your project... I was looking forward to enjoy it completed... please consider just letting it rest in the garage for a while, until you get a chance to pick it up again... it's such a pity, you are so close and so much money, time and effort invested...

@Somchai... Roland may I ask why you ask ? I mean, if sth was wrong with Shawn's setup it wouldn't even rev up to 9 or 10k... right ?

cuong-nutz · June 15th, 2015, 06:05 PM

Spark weak at that RPM? Typical torque peak is around 10k on a regular motor?

Somchai · June 15th, 2015, 06:55 PM

Maybe this is the reason
-----------------------------------------------------------------250R-------------- 250R-FI--------------- 300
Crankshaft Sensor Resistance (Ohms) -----100 - 150-------- 100 - 150------------ 180 - 280
Crankshaft Sensor Peak Voltage --------------3.2 V or more---4.5 V or more----- 4.5 V or more
Primary Windings Resistance (Ohms) -------2.1 - 3.2--------- 1.0 - 1.6-------------- 1.1 - 1.5
Secondary Windings Resistance (kOhms) -10 - 16 k --------10.8 - 16.2 k --------6.4 - 9.6 k
Primary Peak Voltage ------------------------------223 V or more -90 V or more -------90 V or more

The FI-Models only have the ECU for controlling everything, but the 250 carbed has a separat IC Igniter for the Ignition.

Also take a look to the attached picture how the Stick coil cables are connected at the 250-FI (backwards) and 300 (left side and front).

So better don't mix electronics between the different bikes!

Dang, well I am right down the road and I am in need of rear and front wheels. preferably with rotors on them, how much? Not sure what I can affored at the moment just got back from Key West, but very interested.

garth285 · June 19th, 2015, 08:02 AM

I'm selling the set complete with rotors, spacers, metal valve stems and BT-003 tires 110/70 up front and 140/70 in the rear. Tires have about 50 miles on them at the MOST.

Asking $450 for the set but if your local I can make you a better deal on them.
