xaarman posted:The bluing combined with the mega brake fade was what had me concerned. Scoping around, the changes above should do the fix and it doesn't look like the integrity of the rotors were hurt, but I normally expect them to look something similar to this: The blueing is normal, mega fade can be a lot of things. If any single part of your braking system is sub par or not properly maintained, you will get fade as you up the pace. Motul RBF 600 and new pads are a good start. Eventually, you're going to have to start bleeding your brakes every few trackdays or the fade gets really nasty, really fast. Also, if you're using the stock MC, tolerances are pretty loose on those...some are good and some are bad and that can have an effect on fade too.

xaarman posted:Do it, let us know how it goes. My rotors got massive bluing after my last weekend at Hallett, turn 2 is killer. Ordered new EBC EPFA brake pads and RBF 600 to try and fix it, anyone know anything about scrubbing rotors? I hear brake cleaner and scotchbrite does the trick, some people suggested steel wool. something came up, and i wasn't able to make it. i'll make it up to myself by riding some MX tomorrow. on the topic of brakes, see if you can snag an 08+ R6 brembo master cylinder. made a huge difference on my race bike. it got to the point where bleeding it wouldn't make a difference. i'd still have mushy brakes by the end of the day. R6 brembo master or bust!

Forgive my newbie-ness, but how does a master cylinder help brake fade? (legit question, I understand why hot fluid/pads/rotors, but a MC?)

He races a GSXR - they are well known for having lovely master cylinders that are drat near impossible to get a solid bleed on.

Went to Jennings for the weekend, had a blast. The first half of Saturday was pretty much rained out until noon or so. There was a huge storm system that just lingered over us for a solid 5 hours and drenched everything, making the entire place miserable. It didn't help that my tires were crap in the wet and I didn't feel comfortable enough to warm them up to rideable temps. After all the poo poo passed though, it was a great day. There was only 9 dudes riding that day, with only 4 being in my group total (the rest were in a combined intermediate/expert group), and each group got ten 20 minute sessions in over the course of the day. Today was a little more populated, with about 15-20 riders and 6 in my group. Even though it was my first weekend on the SV (and my 4th trackday), I was improving measurably throughout the day. By the end, I had chopped 15ish seconds off my previous best laptime on a 250 and just felt way more confident overall. Shame this poo poo costs so much.      I also accidentally wheelied at the start of the mock race

How's the track surface holding up at Jennings? I haven't been there in a couple of years but I hear that the back section keeps getting worse and worse. It's a shame, because I think Jennings is my favorite track, but it's hard to enjoy it when the entire back section is like riding on rumble strips.

It's still nice there aside from 8 and 9, and even they aren't too terrible because the usual line goes in between most of the patches. I can't speak for the really fast dudes or in regards to racing since I was doing the same line all weekend, but its definitely not bad enough to avoid the track or anything. That said, it would still be amazing if they fixed up 8. One of the harder corners shouldn't be allowed to get torn to bits as the years go on IMO.

The entire day I was so excited that I was finally getting off the bike, and then I get the pictures back and see that everything was moving but my shoulders  Also, with only 3 of them in the track, I was so bad at the right turns. I was even conscious of it the entire day and I still didn't get to the point where they were caught up with my lefts. Any of you that have been, I'm talking about 7, 9, and 13. 4 doesn't count and 14 is easy.

So the first time back on the track since my crash, and it was terrible. I've basically got no confidence in the bike, the tires, or my riding ability. I was extremely slow, even for B group. Every session was all stress and no fun. I left a couple sessions early cause I didn't want to push my luck and crash cause I couldn't focus on anything but whether or not my tires were slipping. Any pointers on fixing where my head is at?

Let your tires warm up, then find someone slow and don't do anything worse than they do.

Don't try to go fast, just try to be smooth and eventually speed and confidence will come. And if you're not feeling comfortable out there, sitting out is the right thing to do.

AncientTV posted:I'll keep that in mind next time. It did just feel generally awkward hanging off the right side, I just wasn't able to pinpoint exactly why while I was there. to add to this topic. dunno how tall you are or how much you weigh but, lets just use this as a general base point for body position. Get half your butt off the seat, butt crack should be on the edge of the seat. balls of your feet on the pegs. rotate hip out, open up your hip to the turn. rest your heel on the heelguard or swingarm. this will stick your knee out. okay thats your lower body. for upper body, like your hips, point your shoulders to the turn, elbows out, relaxed grip on the bars. drop your upper body, everyone says 'try to kiss the mirror', or touch your chin to the bar end. and always light on the grips, hold throttle like a screwdriver/doorknob (that way you're not hamfisted on the gas).your spine should be straight, not looking like an 'S'. oh, i forgot to mention: hook your outside leg on the tank flares. with your bike on stands, and you in the correct body position, you should be able to let go of the bars and stay in position by holding yourself up with your thighs and core. like i said earlier, use that as a baseline to set a body position that is comfortable, and works for you. personally, i like preaching the race line more than body position. if you're on the race like, and running a decent pace, you'll learn body position out of necessity. that, or crash. hope that makes sense. this pic shows the 'triangle of light' formed by rotating your heel in, and your knee out.  drop that upper body  outside leg 'hooked' into the tank flares

Thanks for that, I've heard bits and pieces of this ad naseum, but it helps to have such a complete explanation. I'll see if I can't brush up on it all next time I'm out at the track. Hopefully it'll serve to give me a bit more confidence than I was getting last weekend in regards to comfortable BP. The tips on foot placement should be especially handy, as mine were just kind of floating around both days.

AncientTV posted:I'll keep that in mind next time. It did just feel generally awkward hanging off the right side, I just wasn't able to pinpoint exactly why while I was there. Funny I have exactly the opposite problem... I'm comfortable on right handers but lefts have me confused to some extent. I've never felt anywhere near as comfortable on lefts as rights. I think it's an issue related to the fact ALL the tracks within moderate driving distance of me are run clockwise. I've just had way more chances to practice right handers than left handers. If you have a track near you that's clockwise oriented go hit it up so you get more practice with the side that's been giving you trouble Older pic, but it shows difference in body position pretty well (and is exceedingly exaggerated due to the fact I ride a sumo with knee down, not foot out body positioning)  I'm in the back on the orange KTM (in honda leathers  ) setting the guy in front of me up for a pass with cornerspeed since his 690 outpowered my 625 by a fair amount. I'm carrying roughly the same lean angle as him but due to my body positioning am carrying quite a bit more speed through this corner. Note toe tucked up on the peg for clearance, heel rotated into the bike, not much rear end off the seat, and outer leg locked into what little there is to lock into on the tank (oh how I miss sportbike tanks!). In retrospect, it's not a sharp enough corner to really be in ATTACK position but that's what I was comfortable with. Should have had my knee tucked and just hammered through with my shoulder/head down but hey, it worked .gawddamn I need to do a trackday asap. It's been far too long!

Unfortunately I don't really have any tracks that are both close to me and run clockwise, but I may just hit up Jennings again when they do a backwards day.

Part of me wishes they'd repave the back section but at the same time I know how expensive that is and I think Jennings would suffer if they had to up their prices to compensate. Oh well, I'll still head down there when I get back on the track one of these days. Love that track regardless. Also: Anyone going to be at VIR for WERA in a couple weeks? I'll be up there in the pits that Friday helping out some buddies with their endurance team.

Well, weekend complete at Heartland Park Topeka. Fastest track I've been on, there are three straight aways and lots of flowing curves... really only two that are hard turns. Brakes worked like a champ, so very happy about that. Because of the quickness of the track, it was quite frustrating being held up by people who can pass you in the straights and park it in the turns. The SV is great, but I've been lusting over the already-showing-up-used 2013 675Rs and 636s... Definitely a potential offseason acquisition in my future. Work is taking me to Alabama for the next 2 months so I think I'm done for the year track day wise though = [ xaarman fucked around with this message at 05:07 on Jul 23, 2013 |

Keep the SV till those people don't hold you up in the corners anymore because you pass so well and carry corner speed. Then get the 600. You'll thank me later.
