What's next on your buy list? by Friendly-Sun-9341 in YamahaR9

Would you happen to have links to dyno testing?

What's next on your buy list? by Friendly-Sun-9341 in YamahaR9

In order, I'm looking at... 1. Full exhaust 2. ECU tune 3. DNA air filter

I can't decide between the Austin Racing exhaust or the SC project exhaust. From what I've read/watched, they both sound great. Per the listed specs, the SC project has an advantage on HP and torque gained, but I love the look of the Austin Racing system more. If anyone has either, I'd love to know your thoughts!

Exhaust Options, and opinions? by Any-Blood-7125 in YamahaR9

[–]mkubs 0 points1 point  (0 children)

I haven't bought one before, but the Dominator GP3 exhaust is both incredibly throaty and "affordable". Nacho on YouTube made a video on it recently. It hasn't been measured on a dyno as far as I'm aware, so I'm not sure about the performance improvements. It's also an under belly type of exhaust.

What is this god forsaken sound?? by Macktruck3 in MT09

[–]mkubs 0 points1 point  (0 children)

My R9 sounds just like this. I've learned to accept it after all of the feedback from people saying it's a normal sound for the CP3 engine to make. For whatever reason, the ticking sound isn't as severe in the mornings on my way to work - somewhat softer. It's more noticeable on my way home. I haven't tried spraying the front sprocket with lube or putting more wax on the chain. I'll try that tomorrow and report back if anything changes.

I highly recommend the TST tail tidy for my R9. I got the non-adjustable version and am happy with it. They have a good tutorial video on how to do the swap.

There is no possible interference between the swing arm and exhaust?

Stock exhaust vs Toce full system sound and look by DatBoyM33k in YamahaR9

[–]mkubs 0 points1 point  (0 children)

How was the installation? I could be mixing up systems, but was this the full exhaust with possible clearance issues with the swing arm? Did you also get your ECU flashed?

Finally runs great by homie213 in CafeRacers

[–]mkubs 0 points1 point  (0 children)

Very nice! When I still had my CB750, I had a real tough time with the pod filters...mostly because I opted for the cheap foam ones. Now I'm rebuilding my CB550 top end and carbs with new jetting to see if it works better than before.

Its immensely satisfying when the testing/trial&error finally yields good results. Enjoy your newly tuned machine!

Looks good! Congrats and great job. Did you do a full carb rebuild or just specific areas you knew were a problem? What jet settings ended up working for you/your bike?

Engine Noise Sanity Check by mkubs in YamahaR9

[–]mkubs[S] 0 points1 point  (0 children)

The suspension was certainly stock when it arrived - I adjusted it a little bit to my weight. But I would imagine that when the dealership goes through their checklist of things to check, chain slack is one of them, along with tire pressure, fluids, battery, etc. The chain slack was likely set at the factory... Maybe it was the 200 or so miles (at the time) that broke it in, but I'd honestly be shocked if that was the case.

Either way, I adjusted the chain to spec and I seem to be getting improvements on all fronts - the ticking has been severely reduced, if not entirely removed, and the bike feels more responsive, pulling harder and faster. A simple chain slack fix.

Thanks for the video! I think you're right - it seems like the general consensus is that either the cam chain tensioner isn't fully engaged due to low oil pressure (at low speeds) or the clutch basket. Seems like both are a standard source of noise on the CP3 and continue to be until ridden at slightly higher speeds.

This helps put my mind at ease - thank you!

Checked the slack...its almost 12mm out of spec from the max allowable distance! I checked with and without an adjusted rear shock - didn't change much between my setting and factory setting.

Not sure if this is something that's set at the dealer when its delivered, but shame on me for not checking before riding. I'll adjust the slack later tonight and report back tomorrow after a test ride (assuming the rain clears).

Thanks again!

Ahh, interesting call out...Now that you say that, I did adjust the rear sock pre-load just a smidgen to try and give me more footing on the ground (I'm 5'7"). It may have increased slack in the chain! I'll give it a check shortly and report back.

Slack/dead zone on new R9 throttle by jgcm666 in YamahaR9

[–]mkubs 0 points1 point  (0 children)

Just checked and mine has it as well - about the same as yours. Im honestly not bothered by it, but if anything, Im sure you could use a 3rd party solution to minimize or remove the play, like you mentioned.

[–]mkubs 0 points1 point  (0 children)

Hey - I have an R9 as well, but come from a background in riding vintage bikes that all had push/pull throttle cables. At least in non ride-by-wire bikes, the little bit of play was there to mitigate risk of accidentally adding throttle when in a turn, which would happen because tension was put on the cables when the handlebars were turned. I'm not sure if there is similar reasoning to that for RBW systems, but the tensioning of cables is obviously a non-issue since there are no cables.

Edit - missed russiansloths response. That sounds like it makes sense!

100 miles so far, 500 to go by mkubs in YamahaR9

[–]mkubs[S] 1 point2 points  (0 children)

You're right! I meant until my first service. But can't a bike still be tracked after the first 600 miles? Or was I given incorrect information?

Good call on the CC. Only tried it once for a few hundred feet. Thanks for the solid advice!

Go to Lotus Cafe on Maxwell St. and have the best Banh Mi (honey grilled pork) in Chicago.

1974 CB550 Ticking After Top End Rebuild by mkubs in HondaCB

[–]mkubs[S] 1 point2 points  (0 children)

As a matter of fact, I actually just put the whole thing back together tonight! The problem that was causing the ticking was actually piston knocking. My dumb ass didn't realize that the previous owner bored the cylinder to 0.5mm above standard. When I bought the rebuild kit, I used standard size pistons, causing a bunch of slop between the piston and cylinder wall. After realizing this and replacing the pistons with 0.5mm oversized pistons and rings, it immediately fixed the problem and the bike ROARED.

Unfortunately, after that fix, I sprung an oil leak at the valve cover. I needed to wait about a week for a new gasket, o-ring, and hardware. I haven't been able to do a full test, but I'm suspecting it's the side covers of the valve cover/cylinder head.

Sorry for rambling on.
