Hey everyone, I'm new. I bought a 2013 locally a few weeks ago and I scrambled to order parts and get it built for track/race duty. I'm coming from a 2012 CBR1000RR and a 2012 RC-8R (which I loved). Had a 2009 GSXR 600 and I've had countless dirt bikes. Currently ride a 2010 KTM 250SX converted to a 300SX (2 stroke powa!!!).

I decided to replicate the BSB WD-40 ZX10R. I'm pleased with the build, but I have so few hours on the thing that it still doesn't quite feel like home. It will.

Mods:
Archer Flash
Bazzaz Z-Fi
M4 Street Slayer Exhaust
Woodcraft Clip-Ons
Woodcraft Lever Guards
Armour Bodies Pro Series Plastics (SBK tail)
Ohlins TTX GP Series 2 Rear Shock (Sprung and revalved for me and linear link below - Kyle Racing)
Kyle Racing Linear Link
Vortex Sprockets
DID Chain (520)
Pirelli Slicks (SC2's)
EBC GPFX Pads
Adjustable Shorty Levers
Zero Gravity Double Bubble
Stainless Steel Brake Lines
Pro Grips
Vortex Frame Sliders
1/5 Throttle Mod
Paint from a local shop.
Various decals 'n bling 'ish

There you have it. Looking forward to having some fun with her. I'll probably do a Racetech revalve/springs on the front forks if I need them, rearsets, and an Annitori quick shifter. I can't think of much else I want.

I've been lurking for a few weeks as I read about the platform and how to fix various minor issues I ran into. For example, I still need to tighten the steering stem collar nuts to get rid of the 'clunk.'

Cheers!

Well she does look the part Fo' Sho!!:love10: I'm sure you'll acclimate to her really fast. She is quite different than that RC8R, loved my big twins too.

:welcome: and enjoy the site!

Thanks, man! I like the ergonomics and this engine is just unlike anything I've ever felt. It rips! Tipping into a corner still feels vague. I have a track day Monday (Memorial Day) and I'll get to do a proper shakedown. I will fiddle with the forks to get the front end feel I need to feel comfortable. It's really just a function of seat time. I only have 2 track days before my first race so I really need to get all of the miles in that I can. It will come. Thank you for the kind welcome! Cheers!

Nice dude, I see you don't have a seat pad yet, I'd recommend staying away from the one that woodcraft offers. I couldn't get the corners on mine to stay down for the life of me, tried 3m super 77 adhesive with tie downs holding it down for the drying process. It's just too thick and too wide at the front. I got my seat pad from here: Racing Motorcycle products, race seat pads, performance parts

It's narrow enough in the front so it doesn't want to peel up.

Stock forks are good enough for front pack amateur times I feel, I'm about to upgrade to a K-tech cartridge kit to push the front even further. Also got some good feedback from my tuner on correct pressures to run for the pirelli's. Using the recommended pressures provided by pirelli are way off apparently. I'll report back once I've had a chance to try it out myself. I did find this pdf that has a good chart on the bottom to get you started: http://racecenter.com.au/wp-content/uploads/2015/08/Tyre-Pressures-V3.pdf

Hmm...I did get the Woodcraft seat pad and it fits much better in the front than what you describe. Perhaps they accidentally cut from the wrong mold? I will take a picture when I get it back together. I pulled it apart again because I'm shimming the rear shock up 6 or 7mm. I also added my race numbers since these pictures were taken over the weekend.

We'll see on the forks. I'm lucky enough to have a fairly well known superbike racer as a friend/mentor. His suspension guy will redo my forks if necessary. We'll see how I feel with them. I really like the BPF and the spring rate seems good for me.

Oh my gosh! Thank you so much for that PDF! Great info! I'm coming from Dunlop GPA's (MUCH harder sidewall) and I ran only 22 psi rear. I knew I couldn't get away with that with the Pirelli's. This PDF is great because I'm running the SC1 front and SC2 rear, as is recommended. Thanks a ton!!!

Let me know what you think about the K-Techs. I live around the corner from wicked Racetech guru and we have the K-Tech guys and Ohlins guys in the garages all the time at Utah Motorsports Campus (formerly Miller). On a budget, guys are saying the Racetech stuff can really feel great. I'll let you know how I feel with the front end after my first day. Man, I have a lot of work to do.

I found this hard to believe but my guy said the pirelli rears work better down in the 22psi hot range as well. Gonna give it a try and see what I think. He was also super adamant that the SC1 front is by far the best tire anyone can buy, I've been running mine for 5 track days now, probably have over 100 laps on it and it's still sticking, I've done some pretty stupid shit mid corner and it held just fine. Apparently I was running the wrong pressures in the front too, was running 31 and he said I should be atleast 35 and that some of his guys run as high as 41.

I don't doubt your guy. My buddy has raced wild card in WSBK and I'm going to let him be my guide. BUT, if you think about it, rear tire pressure affects braking/cornering stability very little. I mean, we're trail braking until mid corner and the weight is really probably > 75% on the front tire until the apex. That's where the softer sidewall of the Pirelli front would really come into play and would explain the higher necessary pressures to keep it from buckling, compared to the Dunlops. I'll ask to see what pressures the fast guys are running out here and I will let you know.

22 psi rear was MONEY on the Dunlops. I would lay THICK rubber stripes and there was plenty of grip on corner exit.

Very sharp ride. I would also check out the GP cartridge kit for the front. I have been getting some great feedback from the front with them. I run sc2 front and sc1 rear. It works well in the desert heat here.

Ohlins? No doubt, but I've spent a fortune in the last few weeks. So, I'm thinking the front solution will have to be a budget build or the wife is going to go psycho on me. :crackup:

I've done a few laps with your buddy around Thunderhill. Very good dude!

I agree from experience that the BPF are very good and will run at the front of novice times. They do reach a point where you can out-ride them though.

If you have the Woolich kit I'd advise adding on the race tools which gives you a quickshifter, plus launch control. You will probably get fast enough that the stock TC is starting to hold you back, and Woolich lets you adjust those settings too.

I like the paint scheme.

I use Pirellis as well and I couldn't get comfortable with the SC1 front unless I ran 35psi in it. It was just too soft. The SC2 front just works better for me personally. I use the SC1 rear. I have found that the SC1 has more grip on corner exits and lasts nearly as long as the SC2 rear unless the track temp is really cold.

Yeah, he's a nut! Unfortunately, I don't have the Woolich kit. Being able to adjust the TC settings would be awesome. Unfortunately, I'll probably just turn it off once it starts bothering me and holding me back.

I'm not going to ship my forks anywhere. We have enough resources locally that I can probably have this done while I wait at the track. We'll see what route I go.

I agree about the sc1 rear. It has tremendous side grip and equal or greater life compares to the sc2 rear. I LOVE the sc2 front and run 33 psi hot with no issues. Excellent feedback from both ends. And yes....I meant gp suspension in Washington. It is not that expensive.

Sorry for the mistake. I'm still getting to know some of the ZX-10R specialists. We have so many good resources for suspension locally that I really don't think I'm going to pull the forks and ship them. I can probably get this done while I wait at the track because Racetech, K-Tech and Ohlins techs and trucks are always around. It's partly the peace of mind of having your suspension guys right there next to you while you test things.

I can understand that. I was without my bike for a few weeks when I shipped them off. I had help from Dale Kieffer at Racers Edge to get everything set up. I also put a JRI shock on with the Jeremy Toye link. I wonder if the Attack triple clamps would be worth the bucks.

1st trackday down. Jeez...I need seat time. Everything is so different. New bike. New engine character. Dunlop to Pirelli switch. New brakes. 5% throttle tip in mid-corner at high RPM was abrupt. New freaking everything. It started out rough, but I got A LOT faster throughout the day. On top of that, I'm out of riding shape so I was exhausted by the 7th session. How in hell am I going to race this thing in 2 weeks with only 2 more trackdays before then?!?!?

The rear end felt fantastic on corner exit, but I was a gear too high and I didn't have the torque to pull me out of the hole (-1/+1 gearing) and I didn't have the confidence to take those same corners a gear lower because of the abrupt fueling. Does the Bazzaz clean this up for a smooth transition from off to on throttle? Suggestions?

BWAHAHAHA!!! I saw that race last year. It looks like they left the fuel petcock unlocked or something like that. I'll try to avoid that! Thanks for the tip! hahaha!
I had a brain fart once and forgot to twist-lock the fuel cap after filling up. Needless to say, half way into my out lap, I got sprayed with fuel as the cap flew off, never to be found. Luckily, the bike didn't catch fire and I babied it to the pits. #notaproudmoment
