First track day of the season finally came this weekend! A friend of ours rents out a local track couple times a year. Open track, come on and off as you please. Great group to ride with.

Novelty knee sliders. The spectators liked them, but some riders find them distracting :p

The first few laps always feel so weird. High pegs, narrow bars (as compared to the FZ). But after a few laps it all comes back. These Dunlop GP-A's have great grip and great wear for a DOT tire.

- 5 points to doserdave for guessing the track

- 5,000 points to whomever can figure out why my bike is stuttering. It's a little hairy when your bike intermittently cuts out exiting a corner or when you're trying to go around someone on a straight.

Buck I like the picture with the sparks flying. Is that Calabogie Motorsports track?

Good to hear that you are back into it Buck. This weekend will be number 7 and 8 for this year, for Peggy and me. I've got one of the new Power Cup Evos on the rear for this weekend.... can't wait to try it out.

I wish! I have yet to book any days there. Probably going to run a weekend in July and August. Love that track.

Wow. That's more than I do in a year! I'm jealous.

Both of those scenarios where the bike is cutting out (corner exit and passing) require heavy throttle use. Running too rich perhaps? If you have an EXUP exhaust valve in your header, ensure it's working correctly. I wired mine open after a spill rendered the servo useless and every time I grabbed a handful of throttle the bike would stutter for a second then start pulling like a freight train.

It took me a while to see this thread, but that's an easy 5 points, Shannonville, Fabi circuit. :)
Question for buck for bonus Doritos at the track, why the hell wasn't I invited to this private track day!? :p

That doesn't look good, but at least clutch packs are cheap.
$300 for OEM. Luckily there's a new Yami dealer close by so I didn't have far to pick them up.

Now if this rain would stop so I can try it out.

8 friction plates + 8 clutch plates @ $18 ea plus springs and gasket.

Haven't installed yet. I'll toss them in oil before installing. Some of that nice red coloured synthetic stuff.

Well new clutch went in, and still the bikes shuddering.

Said f-it, a shop can take it from here.

They put it on dyno to replicate shudder, and low and behold - transmission is shot. :mad:

Now to decide if rebuilding transmission, or sourcing used complete motor is the better option. I thought Yamaha's were indestructible!

That sucks... I was talking to someone at the races Saturday who said his R6 transmission is annoying too, and that other racers have problems with their Yamaha transmissions too.

I hope it wasn't my quickshifter that killed the transmission. I put the QS in at beginning of last season, and mid way through last season is when the trans issues came about.

Bike has 80K on it though... and with years of track on it I guess it wasn't going to last forever.

If I don't get it sorted by mid-Aug, I guess I can always take FZ to track.

I've often wondered about quickshifters possibly killing transmissions. I've always felt that if they weren't adjusted just right that they could hurt the dogs, but how do you know it's adjusted right?

Exactly. I fiddled with the fuel cut time until full throttle high rpm shifts were smooth. For short shifting, it wasn't as smooth. There doesn't seem to be a common ground setting that works for various loads/rpm.

I may be hesitant hooking it back up once I get the bike sorted..
