    Default Newb with Exhaust Question

    Just brought this one home 2 weeks ago. A 2012 Gen 2 with Scorpion slip-on and Renthal bars and only about 3500 miles when purchased. Enjoying the crap out of it thus far. Never owned a Yamaha street bike before nor a 4 and this one's a gem certainly.


    Couple quick questions.
    1) Previous owner did not map the Scorpion but he did gut the airbox or something of that sort. I'll try to dig more and find out exactly what he did. But anyhow, the bike runs fabulously well most of the time and makes some nice noise, but the noise (even with db killer in) starts to wear a small bit on me after about 200 miles. And too, as with most untuned slip-ons I've ever had it has that uneven idle and is a slight bit jerky at low speeds. It's nothing that bothersome and I know most folks would tell me to get a pc or something of that sort but honestly, and don't shame me for this, I am considering just putting the stock muffler back on it but I'm unsure how it would do with his airbox mod?

    2) Also, where is the best place to get a longer brake line for the bike?

    Nice ride!

    What is your idle RPMs set at? You should be showing 1250-1300 RPMs. Below that, the bike will fluctuate. Scorpion slip-ons are notably loud Check to see if the CAT was removed too. I have a Two Bros with the P1 tip and it is a deep note but still quiet enough to not bother me.

    As for the brake line, did you put those bars on or did it come that way? If it came that way, maybe consider the OEM bars? Partshark has them fairly cheap if you don't have the originals and it would be cheaper than new custom brake lines. If you like those bars, then contact HEL and ask for a custom FZ1 set that is 3" longer. this will be two lines with a double banjo at the master cylinder.

    Good luck!

    Got a Vstream shield today and initial run seemed to work better for me on the highway than stock but it'll take more miles to see.

    You know, I haven't even checked the idle speed; I'll note it next time I ride for sure.

    Guy who owned it before me put those bars on it. They are really nice Renthals, seem to be vibe free as well. But to bring them back further I can reroute the clutch line to make it work if I had to but that brake line is too tight as is so I will definitely check into a custom brake and maybe clutch line too.

    Also, I just received my 16T sprocket I want to install. I did the same with my 950 KTM and it really did the trick. I'm enjoying the FZ now but yowsah, I don't think nor hope I'll be running 150 on a regular basis though I did find myself nearing it the other day (man this thing is scary fast in that upper register, gotta watch myself ) so I'm probably gonna go down that one tooth just to get a slightly better jump off idle. Or at least that's what it did for my KTM and didn't seem to negatively affect highway work much either; hoping it does the same here for the FZ. But quick question about that. I haven't even greatly eyeballed the process for install yet. With my KTM it was lift rear, loosen axle, completely slack chain, pop off sprocket cover and nut, remove, replace. Is that the basic process here for the FZ or is it significantly different in some way?

    Get your Ecu flashed by Vcyclenut. He can correct your speedo for the gear change and fix your fuel map for the airbox and pipe for $200. Best money I spent

    To replace the front sprocket on this one, you will have to remove the shift linkage then the bolts for the cover. The cover also holds wiring and a coolant hose in place so you'll have to carefully work the cover out. Try and get the lock washer bent out of the way and the nut loose before going slack on the chain. Without an impact driver, it will be tough to get the nut loose. Once loose, you can go slack and pop out the sprocket.

    Did you buy an after-market without the rubber dampener or did you buy the 2001-2005 Gen I OEM sprocket (dampened)? Gen I was 16T stock. I have one in the garage from my 2009 but never put it on the 2013. I'm already doing bad enough with fuel...

    I got a JT sprocket. But hey, I'm with ya on the mpg. That 950 Supermoto (rejetted carbs and FMF muffs) drinks gas like gatorade, getting about 29 around town and at most 35 on the highway so I am loving the FZ's ability to do respectively well for tank range while still being a very performance oriented bike. Maybe I'll reconsider that 16T or at least think about for another several 100 miles before install.

    I also just bought FZ1, its a 2010 with very low km, 4200. I like the stock exhaust, it looks OK and is nice and quite with a low rumble. I put a yoshi exhaust on my previous bike, a FZ8, and after a year put the stock back on, it was hideously ugly but I couldn't stand the loudness of the yoshi on long trips.

    Welcome to the forum!

    I'm a stock exhaust kind of guy, too. My FZ1 had a stock pipe, as did my 919 and my current VFR. I've purchased a few bikes that came with aftermarket cans but I found myself putting silencer baffles in pretty quickly.
