Honestly, isn't this just a port job with an ecu, cams, and a high compression piston? Who is going to pay 3.5K for that?

Fully assembled by JGRMX engine techs and ready to install
Kit includes assembled cylinder head, JGRMX-spec camshafts installed, GET RX1 PRO ECU (with WiFi-Com, two-position map switch and installation instructions), JGRMX high-compression piston kit, head gasket, base gasket and NGK spark plug

$3500.00 sounds outrageous to me. Yikes.
No ecu in my case though.
I would love to have that full setup for my rmz but if I was going to spend 3-4k on something it would be towards getting A kit suspension not my motor.
new valves - 360
valve springs - 40
buckets - 200
keepers - 5
retainers - 40
1100 ish
Complete Cams plus race ground - DCR cams is getting 1200 for billet sets right now
Then CNC port it - typically a builder retails this service for 600-900 these days at minimum
plus a race piston kit - 350
GET ecu - 900
Assembly - 200
Custom developed maps - priceless
My loose total is 4600 off that
Can you take your EXISTING parts and modify them for cheaper?
Yes
Does JGR want to deal with any of that bullshit - NO
In my world - 4500 is a drop in the bucket for a high level race engine. A twisted build or proven build is generally quoted around 10k - OTD maybe a little less

Here's some facts, the RM-Z450 is the same horsepower as the Kxf and Yzf, and it has more torque than the kxf, yzf and crf and almost identical to the ktm.
The RM-Z450 is only 1 pound heavier than the Yzf and 2 pounds heavier than the Crf. The suzukis are very close to being an amazing bike, but people think they're down 20hp and 50lbs overweight.
With the JGR package, these motors would be absolute rocket ships! Throw on some WP cone valves and traxx shock and you have a serious weapon of a bike.

Buy a-kit for 3500 keep stock stuff.
Put stock back on when sell bike. Sell a-kit seperately for lets say 3k. Your out 500 and had a-kit the whole time.
Buy jgr package for 3500. Put back to stock, sell kit for 2500?
Your out 1000 in my scenario vs lets say paying 700 for porting alone that wont add any to resale value and many times even hurts your selling power.
As for putting it back to stock when you sell it and the parts, good luck with that too.
I have a 2012 RMZ450 that does not see a lot of ride time. Stock it was far from slow but I felt like I shifted a lot. So I did a few mods, one at a time.
1) -Ported the head for low to mid power. (kept the rest stock)
2) -Moto Tass air4orce
3) -Crower cams (This mod really spread out the power) My theory was to use the cam and Vortex to spread out the power.
4) -Vortex (may be the single best mod)
That was all done by me. I still run the standard Vortex map(s), so there alone I’m leaving some more tuneability in the table.
I also do use race fuel. The question I ask myself is that if I had the time and money I would of like to try a HC piston, with stock Cams. I was told the stock cams on Suzuki are good. The point is that JGR did all your homework for you, took all the trial and error out of the process. So you can know it’s done right, and reliable. I don’t think it’s a bad value after doing what I have done.
Now selling the bike & recouping the cost is a another topic for dicussion. Suzuki is far underrated as a mx machine imo.
Yes I’d rather buy a RMZ and make it like I want it, then buy a Orange or white bike for $10,000.
