Race Bike Build

Recommended Posts

Next was the slipper clutch. I was really excited for this.

A slipper clutch is far from necessary, even for racing, but my first bike (which I bought race ready from another racer) had one, and I can't imagine racing without it. Not having to worry about rev matching as you're coming in hot to turn 1 at the end of the front straight is absolutely worth the price tag on the slipper. Also, the confidence you gain when you down shift and dump the clutch the bike just purrs as the slipper controls the back torque just right and the bike turns on rails. As opposed to riding a bronco when you screw up the rev match and the rear starts hopping around underneath you.

I drained the oil, and got the clutch cover off.

I forgot to take another picture of the new clutch installed. I feel foolish. It was a little odd, all the spring bolts and retainers stood about 7mm proud of the pressure plate after torquing the bolts to the 5.8 ft-lbf as per the Yoyodyne instructs and Yamaha service manual. This had me a little freaked out, so I sent Mossrider a panicked private message, and he assured me this was normal. So I continued to reassemble everything.

I took the opportunity to install my case savers as I was reassembling the clutch cover. I bought the Yoshimura case saver kit, and the clutch side guard covers one of my safety wire points, so the bike got its very first bit of safety wire installed.

From there it was just a few more bolts, and a quick google search for instructions on the Yoshimura case savers to figure out which bolts and spacers belonged where. Weird that the kit doesn't come with instructions.

I poured the oil back in. I foolishly did an oil change in the fall at the end of my riding season, so it was brand new oil that I drained from the engine.

And that's about all I got done this weekend.
Now I wait for the damper rod tool to arrive so I can keep going on the forks.

 

I love your guys' feedback. And it's cool to hear about what you guys have done different.

Next time you pull the clutch cover just tip the bike against your workbench (or use the kickstand if attached) and you won't have to drain the oil. 😉

A couple more fasteners you may want to wire/drill depending on your rules package;

Exhaust can to head pipe junction, exhaust hanger bracket to frame juncture, backside of brake lever fulcrum and fasteners depending on manufacturer, silicone on the stator cover center cap and the cam chain safety plug on the right side of the head.

Looking good! I wanna do another now too.

PS, here's a look at mine, same 7mm you mentioned, meh

Yeah, I figured I could probably put it on the side stand and save draining the oil, but my "lift" doesn't really accommodate the side stand, and it was more work to get it down off the lift.

I've never thought to safety wire any of the exhaust hardware, it's not required for my club. The brake lever bolts will all get silicone, but no safety wire.

I have a manual cam chain tensioner on the way, so that will have to wait. But that's a good idea, I'll have to safety wire that plug.

Come to PHX and do mine too :P

Looks good! I am going to be doing the same thing after Christmas but putting in a Suter instead. I too changed the oil before putting it down for the winter like an idiot. I may try laying on side but will be hard on the lift. 
Why Yoyodyne instead of another? I think I know the answer but just curious. Nice build you have going!

By the way, did you get that swapped in w/o piching your fingers? You are better than I, lol.

When she's done and if you're ever in the neighborhood I'll buy you a sprint race at BIR. Be fun, we have at least a dozen of these fool things running around any given weekend trying to beat up on a dozen or so Suzuki's and a bunch of Kramers and whatnot thrown in.

I have already bought my bandaids from your recommendation. Lol

You only have to lean it a few degrees, enough to let oil sump to the left.

I bought a Yoyodyne for my wife's R3, and it worked great.

Also, Yoyodyne worked with Andy Palmer to develop the slipper for the FZ-07 to make sure that it provided good engine breaking and didn't just free wheel, without being too aggressive. This sounded really good to me, so made for an easy decision.

I didn't have any issues with pinched fingers at all. Might be that all the safety propaganda at work about staying out of the line of fire is actually good for something. Or maybe Moss just likes to put his fingers where they don't belong 🤷‍♂️ 😝

I definitely want to come down for a race round once I get this thing built. If for no other reason than to meet the guy who convinced me to build this damn thing in the first place.

It's a really long drive from Edmonton though, so probably not in 2020, hopefully in 2021.

I get blamed for a lot of stuff, most of it not so good. You never know where these fingers have been.

And if you can get to Winnipeg, I can get you the rest of the way, we have a crew that comes down from Peg every month.
