  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

New exhaust worth it

Finally got past the break-in period. Changed the oil and checked the valves yesterday and got up extra early to act like a retard before work. FUN! So now I would like to get some extra ponies. Already have the power up kit and was considering a new exhaust. Is it worth the money? On my sportbikes I basically got them because they sound better but the stock exhaust sounds good on the Husky. 3-4 horsepower on top of 150 doesn't really make a difference. Can you get the same 3-4 hp gain with an exhaust on a 510. I'm guessing that you would feel it because it would a larger percentage gain but I don't know.

Are you running the stock exhaust with the power up kit and what year is your bike?
Different years perform differently with the stock exhausts, my 08's stock exhaust is a very heavy restrictive single item, I run a full dual Leo Vince now, not cheap I admit, but looks and sound the dogs. It also has bigger headers than the stock items and is far far less restrictive. I dug out a dyno graph from an 08 SMR with the power up kit and i beat tune, and it was showing about 48hp and jut over 30ft lb of torque, which didn't seem that great (see thread for SMR510 dyno results). However when I had mine dyno'd the other day it ran to just over 54HP with about 38ft lb of torque (the torque and power came in earlier and remained longer as well)
Admittedly I am running a PCV and Autotune as well, but it gives you an idea of what gains can be made (from an 08 at least)

Holy crap! That is a huge gain. Yes I have the 08 with the cat in the exhaust. 6-7 ft lb of torque would make this thing a monster. Time to go shopping. I wonder if a PCV and just the arrow that comes with the power up kit would give me a large gain? Don't really feel like paying $2k for an exhaust on a $5k bike.

Get rid of that stanadard exhaust, it really won't run correctly with it on (and also weighs as much as a small moon!), get a second hand single arrow or similar, I can't speak highly enough of the PCV and the Autotune is also a no brainer in my opinion.
The original headers as fine, my Leo's are slightly bigger in diameter, but I have no idea what difference that makes (may give a little more torque).
The 530 kit is apparently superb, and defo' a mod I will be doing when/if I ever need a top end rebuild, I gather that the torque it produces is the most impressive thing about it:thumbsup:

Good luck

Dave
 
you could gut and shorten you standard can if you can weld 1mm stainless steel ,
cost me about £50 { packing , 2inch Perforated tube, and tig gas ]
took me about 6hrs in total to do but i did have to learn how to tig weld and i did not have a workshop, i also made the endcap removable so i could repack ,
the alloy arrow can costs £360 [$500 ] here in the uk
 
Will definitely try the 530 kit when the time comes. Going try the Arrow exhaust with the PCV. Thanks for the tips.

Get the Autotune as well, superb bit of kit:thumbsup: Otherwise you will have to get it set up on a dyno:eek:

Dave
 
I know a guy here in town that is willing to tune it just to say he's done a husky so I might give him a try before throwing the scratch down for the Autotune. Don't really take it outside of the state so autotune isn't necessary if he can get it close. Can't wait for some more torque, this thing is fun already.
 
You could also look into Leo vince, Adrien Chereyre runs dual Leo's on his bike to race in the FIM series over in Europe!

That's the same as my exhaust, and I can't speak highly enough of it, the problem is that I had to sell an internal organ to buy it:eek: I think our friend wants to do it on a slightly tighter budget:D

Dave
 
I like my money and where it has got me today by keeping in my pocket... Improving my riding skills will make me go alot faster than throwing money at my bike ...
 
I didnt necesssarily mean go out and buy Leo's dual setup. Just look for a single can setup off someone elses bike. Used or maybe a shop is discounting their in stock exhausts.. Look around Brandon, You may find something.

And yes, The indian needs improvement before the canoe does!

For everyone's benefit you need to put what bike you have in a sig or something. So many differences between models the last few years it helps other members help you better.
 
I have in my husky sm510r 2010 with twin arrow slip on, are those front/mid pipe on leo´vince fit my bike:excuseme:

I would be surprised if they would to be fair, for the money they would cost I would keep the standard headers etc. I bought my exhaust as a complete system so it was not an issue and probably didn't cost much more than the Arrow slip ons either:confused:
