heh, i have never paid more than about $35 a month to insure any of my bikes, that makes no sense to me. motorcycles are high risk but low chance of doing bodily harm to other motorists beside just killing yourself.

i've been riding for almost 30 years and have never been in an accident on the street, but i also don't always ride casually either. if you get on your bike with the intent of focusing every bit of your attention on your surroundings and your job of keeping control of the bike, and not doing something moronic then your chances of crashing are much less than if you don't.

i also always try to avoid riding in the rain, you have less than half the traction of riding on dry pavement, hence you need twice as much room to be safe which isn't always available.


motorcyclists should be given incentives to not clog up highways, not be punished with assinine rates even if you are a proven safe rider. they use less gas and take up much less space in cities which are turning into parking lots filled with SUVs and minivans.

Given proper tires a bike can have amazing performance in the rain (watch a wet MotoGP race to see), but it ain't the water that's gonna get you on a streetbike, it's all the oil and coolant that cars drop.

all the variables on the street i don't trust to stop the same from one stretch of road to the next, quite different than being on the track with wet track tires versus commuter hard tires. my duc spins the rear just accelerating from a stop on our crappy street asphalt.

After gaining some respect for the machine (and an appreciation of how terrible their skill set was), reinstall the frippery and carry on.

And yes, I have seen with my own two eyes people crash in the parking lot, not 100 yards from point of delivery.
Nowadays with new riders, you just throw on sliders and cheap chinese fairings until yor first crash, saving the good stock ones for after the crash.

As for crashing in the dealer parking lot, I am always am amazed how many experienced riders can't seem to get through their head that new bike tires are slippery!

Mufflers were straight through style but not true straight thru. Kinda like this:


Idled fine around 750 to 800 rpm. After the streetport which included a med sized exhaust port(pineapple EP2) the idle was rough and a tad lower. I've got it idling between 800 and 900 now but it wasn't via the idle screw as it did nothing as you suggest. Had to play with the stop on the secondary butterflies but I had it all screwed up and idling at 1500 in the process. I think in the end I had break out the feeler gauges and reset the gap between them and the bore to the spec in the FSM to fix the idle, and then increase it slightly with a little larger gauge to get my idle up.

ETA: Always had a 180 degree thermostat, though the current one is a Stant. Previous was OEM.


Basically the same as you, other than the actual exhaust itself. I have 3 "actual" straight thru mufflers with one of them being in the factory cat location. The lower idle around 450-500 doesn't hurt driveability at all, so I never really took much thought into finding a way other than messing with the idle set screw once and it was ineffective.

I know the sound it is making is from the increased overlap, even though it isn't extreme, and the lower idle because of the same thing.

I need to make a video I guess, just not in the position to do it right this second...if it's slow at work tomorrow I'll make one. It actually sounds cool.

not really, but i meant without trying.

most people just don't respect bikes or the fact that you are so vulnerable on them.

I thought I would never down my bike, but I believe in "dress for the slide; not the ride"

I was on my way home one evening and hit a deer almost broadside on my bike at about 30 MPH. Never tell yourself it can't happen to you, because it will.

In my opinion, it's not a matter of IF, but a matter of when you down a bike.

in sutations like that it is unavoidable. i first learned to ride offroad, you learn to respect the pains you have when you hit the ground. i have dumped my dirt bikes more times than i could count and i still have pains from some of those wrecks 25 years later.

That's how I learned. My dad bought me a 125cc vintage Honda that we turned into a dirtbike. Downed that bike way too many times, but loved every minute of it.

I have all but stopped riding daily, because my commute is too far and in heavy traffic. Can't split lanes here like our friends to the south, so idling in traffic becomes a nightmare.


When I hit the deer, time slowed down and I knew I was going down. My only thought was "This is gonna hurt" BLAM "Well, that wasn't too bad" Fortunately, I was in all of my gear and I was able to walk away with bumps and bruises.

I actually could have left mine alone and for a few days until I figured out how to fix it with the FSM I wished I had. I have those 2.5" straight thru ones I posted earlier in the thread now but with that undersized y-pipe from this thread: https://www.rx7club.com/2nd-generati...-pipe-1079591/

Never have gotten around to learning to weld even though I've come into a flux core welder. Just too busy with other stuff right now. I need to make a new video shootin' flames and post up for the O.P.
