Today I added more POWAH to my bike. Only set the plastics* on fire once!





Hopefully my hand will be healed and I can test it out this weekend.

*slightly melted the plastic sheet used to hold the wire bundle together behind the front fairing. I got it out of the way once I realised it was melting.

Trying to crank with a low batt can kill your starter and/or sprag clutch, neither of which are generally cheap / easy fixes ('specially the sprag.)

I only tried it once and immediately realized what happened. Addressing the wiring in my bike is the next project. I want to put in a usb outlet and check the main wiring harness for rubbing since that was apparently a recall which was never done on the bike.

Finding out where the edge of the razor is, turning to face the darkness and revving his 690 into it's vast gaze. You gotta live this to learn it bro.

FWIW pushing the pistons back against the master cylinder is Not A Good Thing for every component involved. I don't give a gently caress on cars and do it anyway, but on bikes I prefer to open the bleed screw and push them back. Also means you don't have to worry about trying to siphon down the fluid in the reservoir. Especially if you have a cast alloy reservoir which is painted, as opposed to the plastic sort.

Obviously, don't do this unless you have some kind of hose to put over the bleed screw and direct the fluid somewhere other than your bike :v:

Why? I can see no part in the system that would be stressed by fluid flowing backwards through the system - yes, the fluid is moving through the bleed hole in the reservoir vs. a bleed screw, but the concept is the same. And if your braking system can hold max pressure hard on the brakes, the force of your fingers pushing in on the pistons is nothing. That goes double if you eject the pistons with air or a grease gun.

I know. I used to use that exact argument. And yet, having seen a couple of bikes get hosed up this way, I now do it the 'proper' way.

Also some ABS systems don't like it either.

Abs is a completely different setup - each system has it's own quirks.

What broke on bikes you saw getting screwed up by doing that?

Master cylinder. VFR400 nc30 (mine) and VTR1000F (my mate's). I think if you have a tired brake system, doing that just pushes it over the edge.

Putting aside weird systems like some ABS, I can't picture why this would be true. When the master cylinder piston is at rest, there's free flow of fluid up and down through the system through a hole in front of the piston. Pushing the caliper pistons in will just push fluid up into the reservoir. Unless the reservoir is full and the cap is on tight or something.

And actually, the weirdest ABS systems I'm familiar with (BMW) will behave the same way, despite not having a piston. Push the caliper pistons in and it'll just push the fluid level higher in the reservoir.

How is pushing the cylinder with a c-clamp different than the cylinder being pushed by the brake disc after you let go of the lever?

Slavvy
Dec 11, 2012

The disc doesn't push back the pistons appreciably, most of the 'pulling back' is done by the piston seals themselves.

My theory is that the sheer volume of fluid being pushed back when you use a clamp is somehow more than the system is designed to deal with, and a tired MC just gives up. I really don't know, I know it doesn't make much sense, but I've heard of it happening to other people too. Not to mention the majority of car mechanics don't like doing it either for *reasons*, but cars are so much more robust than bikes in general that I don't worry about it.

It could also be that either of those bikes had semi-seized caliper pistons and that getting a fresh MC forced them back out the way a lovely old one couldn't.

If there was crud in the calipers and you force all the fluid up and out you're going to probably deposit some in the MC, where it could gently caress up your already tired piston seal.

I put the cover back over the back half of my seat. Something the PO has mounted, little plastic thing - I took it off when I got the bike, but since I removed my rear passenger pegs I thought it needed a little something. Looks pretty nice.

SW-Motech mount with givi adaptor.




A whole lot of room for junk in the trunk, Givi 55L top case.


Really like the Motech replacement grab bars and mount, and that when I don't need the case removing the adapter plate is 3 easy quick release screws for a cleaner look/strapping poo poo onto it direct. Well worth the increase in price over the givi rack.

The hardest part of the drat install was getting the grommets in the givi adapter plate, I gave up and put them in a slightly larger hole, but they are still held in decently.

I thought I was good on maintenance since it's only been about 4 months but happened to check my spreadsheet (yes, of course I have a spreadsheet for maintenance) and realized I did my last O&F change over 5,000 miles ago. I put on way too many commuting miles and not nearly enough fun miles.

Nearly dumped it while dicking around off road, then went to get some fuel and aired up the tyres to find out they'd dropped to single digit PSI levels :ohdear:. Hadn't been riding for a week but I was probably on under inflated tyres for a while before then.

2008 drz400. Changed oil, oil filter, and air filter. I cleaned, lubed, and adjusted the chain. Finished checking the rad and brake fluid. Noticed a bolt missing from the side cover on the exhaust side. Removing the remaining bolt to match it led to cranking the rear spring adjustment all the way down and turning the slow speed valve all the way in to accommodate my 300 pound self. I can hardly believe the difference. Now instead of the rear end dropping and wallowing around when I gas it, it just goes. And now it wheelies better. The bike is 100% ready for March Moto Madness this weekend in Tennessee.

Sure why not
Installed the after-market pipes that came with the SV1000 I bought a couple of weeks back and took the bike for a spin. Jesus Christ, I sound like an rear end in a top hat now. These slip-ons are so loud it actually hurts my ears to give the bike any revs, and I can see heads turn as I WUD-WUD-WUDD down the road. "Oh look," bystander expressions say, "there goes a man with a tiny peen."

SAD FACT #1: Even these ridiculous cans can't mask the high-pitched overlocker whine of the engine so the bike still sounds so-so at best.

SAD FACT #2: The previous owner installed a power commander and had the bike dynotuned for this exhaust, so the fuelling seems off for the (otherwise fine) stock exhausts. Either that or I have a previously unknown affinity for coaxing backfires out of motorcycles.

IDIOT QUESTION: Kind of sad to lose the (alleged) additional horsepower the previous owner's mods gave the bike, but I'm yanking these bullshit exhausts back off tonight. Would it be worth keeping the power commander and installing a downloaded map for standard pipes? Is there such a thing as a repository of PC3 maps?

All 4-stroke engines backfire (or crackle and pop) to some degree. How audible it is depends on carbs vs. EFI, cylinder size, exhaust, emissions equipment and a bunch of other factors.

My old bike had a completely free-flowing exhaust (no emissions equipment of any kind), backfired like a mofo, flames shot out of the exhaust when hitting the rev limiter, and it sounded like popcorn when engine braking. The mixture was spot on, exhaust temperatures were dead even across all four pipes, carbs were synced pretty good. Everything was as it should be, but it was still flatulent.

Even my reasonably modern current bike will pop if I rev it and snap the throttle shut, and crackle on deceleration, despite being completely 100% stock with cats etc. intact.

All you need to recreate it is to take an ancient carbed and oil-cooled 4-cylinder, and throw a completely free-flowing exhaust on it. You get a nice uneven idle to go with it, too.

My friend's Ninja 636 shot absolutely insane flames constantly - nothing wrong with the bike and I don't even think it had a tune - but it did have a completely straight through exhaust.

Probably depends on how picky you are. If you buy a bike with a Power Commander, make sure you load it up on your computer and check the map! The PO could be a huge dummy. I had a PC3 and Scorpion exhaust on a FZ6 and it ran rough as hell on the low end. I loaded up the PC to mess with it one day and the PO had the wrong engine map installed. I downloaded the stock PC3/Scorpion map from their site and it was great! PO's can be dum.

It wasn't a perfect map or anything but it was good enough. Sure it would have been better if I had got it done at one of the dyno shops that tunes them.
