.....but I can't stop, it's just too fun. Lol. Yeah I've put a ton of stupid crap on it that's a littler overpriced and most definitely not needed. But this is the first bike I've ever truely built on my own and learned the mechanics side of things after 11 years selling parts in the motorcycle industry and racing off-road for several years.

No carbon wheels for me. I would love them, but I'm not set up with them as a dealer and I can't afford to pay retail for them. They are badass though! Considering doing the Grom wheels swap just so I have some other options for wheels though. But I just did the powder coating and rotors, so I don't want to switch immediatly. Lol I gotta recoup some of my money first!

Beautiful build. You better keep it for a good long time to get your money's worth of enjoyment out of it. I can understand how easy it is to dump money into a bike. My old ninja 300 race bike ended up costing me $10K. And I lost more than half of that when I sold it. Every bike after that I'm pulling in the reins on spending.

A cool mod for your bike would be a map switch and adding a 2nd tune for MR12 race gas when you get it on the dyno.

Edit: wait, that's not going to work with the Bazzaz, it has no ignition timing. I did a MR12 2nd tune on my 300. But I had a PCV which allowed for ignition timing changes.

Regarding performance, carbon wheels are generally wasted money on these little bikes. The small wheels already have low unsprung weight, and with superlight wheels the bike loses some of it's gyroscopic stability. Then it's a little too flicky and skittish, moreso at the higher speeds a BBK allows. Carbon wheels sure look cool though - the ultimate bling piece.

Learn something new everyday!
Thats a very good point about wheels losing some of its gyro precision. I have no plans on getting cf wheels just because of the price. I wonder if they might still be beneficial to super good rider that is competing at a track though.
Neat stuff!

Carbon wheels may have a good benefit at slower speed kart tracks that are seriously bumpy. Might help to keep those tires planted rather than bouncing around.

I feel your pain. I went though this on my ZRX. Dumped what I call Harley money into it. I won't recoup a third of what I spent unless I part it and then maybe half. But I still love it. lol....

I am trying HARD to leave this thing relatively stock. I am having a hard time with that. lol...

Me too, on both accounts. I have already ordered parts for the Z125 and the bloody thing is not even in my garage yet, I blame @Greedy.

I also have the Pro Circuit T6 exhaust, will be fitted for me when I pick up the bike. Just trying to resist the Ohlins, I had Ohlins front and rear on my ZRX and it was awesome, I imagine the Z125 would be the same.

Out of all the mods you did Bryan, what ones gave the most benefit do you think?

Love the build out. I see some things on that list I hand’t Thought of (dammit). The Galfer lines, rotors, Brembo caliber, etc. I’m struggling with $1000 for a full Ohlins setup but we will see how it does at the track that might get the nod. Your right its WAY to much fun.
