Update on all mods done on the hawk. Questions about baffles? - Page 2

I'd either remove the cat (if you have access to a welder) or replace the header with the non-cat version, per BlackBike's recommendation. Once the cat is gone, you can re-jet to compensate, and see if there's a benefit. After that, you can decide if you want a new muffler.

Agreed,
First, going to do the simplistic solution and remove baffle. Test, if it's not satisfying I'm going to run the bike at least another few hundred miles before messing with the cat or thinking about replacing. Thanks for the advice.

Removal is ok for testing, but I don't recommend poking a hole in it. That's not easily reversible.

what about the weight of the stock muffler? an unrestricted header and lightweight performance muffler will make a noticeable difference with the right carbie setup.

One of the most important things you can do is keep your options open until it's broke in. These CG motors change personality continuously (at least all of mine have) until they're loosened up.

I'm one of the few who can't afford to lose any more weight, my motorcycles have to do that for me

So once my friend gets his TIG welder I will drop a good 15 - 16lbs off our Bashan WILL exhaust system

, that combined with weight I dropped off when I ditched the bulky air box/emissions nonsense that 'didn't do squat' for a UNI Pod Filter... the bike is almost to that "20 lb diet requirement"

, and it should have a few extra ponies too the way the exhaust was restricted on our bike

Removed baffle last night did maybe 20 miles to test. I couldn't really tell differences it felt more stable at 60ish but I also removed my rubbers from the foot pegs. Also, it felt like it let open a little more while at full throttle. But nothing substantial to report on preformance. Sound wise, a 100 times better it sounds really good with the baffle removed. I would recommend this to anyone, just to have a little louder exhaust to make people more aware around you. i think this is all I'm going to do with the exhaust for awhile I'll update when I decide to swap it or mod it anymore.

You probably won't notice much as long as the cat is upstream. That's your main exhaust flow obstacle.

after tailpipe change , single biggest weight lost gain, swap out the battery for a lithium job. gotta b 7 or 8 lbs and balance feels LOTS better.

i'll have to take some pics.

but basicly, the bracket and nuts (Rear slider) that are used to to tighten the chain they are shit. so i swapped them for better washers and nuts.

the chain guide, is the rubber piece on the frame that helps guide the chain into the countershaft sprocket. on my bike if you lined up your sprockets perfectly this chain guide actually will not line up with countershaft. so i got rid out it, this won't necessarily throw the chain, but it's not helping.

pcspecialist · 05-13-2016, 04:37 PM

so you didn't swap the chain guide, you simply removed it?

I was thinking about filing down the ridge on it so it no longer guided the chain but did protect the swingarm.

yes i finally removed it. i did try to swap it with a old honda chain slider but couldn't get that to quite line up either. also just filing it down is probably a better idea haha
