Hello all, Raining in Southern California & bike in for 620 mile service leaves extra time to obsess over the important stuff. Would greatly appreciate any input regarding your opinions on which would be an easier install overall, the Jardine slip-on exhaust, or HMF's slip-on. I'm just being cautious in not getting in over my head with the install. I'm leaning towards the HMF, however if the Jardine is a considerably easier install I'm sure it would fit the bill. Your thoughts on me having someone else install it if I deem it to be too difficult (just want to stay within my mechanical limits). I will go with a K&N air filter, my final question... Is a fuel mapping device mandatory, recommended, or could I just install the pipes & air filter with the primary goal being for sound and street usage. Thanks a bunch for your input. So many threads on exhaust that I wanted to start a new one to pose my question. | ||

A fuell mapping device is not recommended. A well made fuell map is recommended FYI:Tthe 2009 AMA championship winning 1125R used a stock filter. IMHO: Stocker is washable and breaths great. Get the K&N if you like oiling a filter. | ||

Common man I'm ridding my CR through the rain. riverside to LA and back every day! its sooo fun doing 110mph burnouts in third  | ||

Rock On Capt. America!  Super Power's, indeed! Tornado warnings & flooding no less. You've earned your rank, that's for sure. I'll just blame it on my bike being serviced. No excuses after Thursday morning though! | ||

Barker, Thanks for the info. When you say "stocker", you are referring to the stock air filter, correct? Made your point nicely with the AMA championship win. When I mentioned the "Fuel map" (which is very new to me) I was meaning something like the Jardine Pro tune 3 Fuel Programming Card, which apparently "Fuel control without altering the stock fuel map". Again new to me. That's why I'm interested in all info & opinions. Is there a HMF equivalent, and are either necessary when putting on the slip-on pipes? Thanks again. | ||

Ok, I think I found the HMF equivalent... The "Optional" Z-AFM Air Fuel Mapping Kit. The optional part may answer my original question. I also think I understand fuel mapping better than I did 15 minutes ago. Still interested in any & all info & opinions. Thank you much! | ||

I've only got 90 miles on my 1125R but so far have been pretty happy with the performance with the stock map while cruising and while under load. I don't doubt that there's some performance or rideability improvements to be had with a custom tune, but $300+ for what is basically a mail order tune is way more than I can pay with a clear conscience. I do plan on either having my stock exhaust modded or buying an aftermarket/custom slipon, but I plan on seeing how the bike responds without any sort of assistance. I do recall hearing from at least one rider who changed the muffler and switched to a K&N and had the bike running poorly, presumably due to being too lean. Perhaps the K&N pushed the bike over the edge into not running well. I'm primarily interested in better sound as opposed to more power, so I won't be doing a K&N. My point being that you could just swap out the exhaust and see how the bike runs before deciding on a tune or a tuner and a K&N. | ||

Great point. At this point that will be the plan. Still heavily leaning towards the HMF slip-on. No K&N air filter and only a tuner if necessary. Thanks for all the input. | ||

The jardine run extremely lean. It's been posted numerous times. This is without a k&n. | ||

Just remove the inner air box and de-noid the thing so it doesn't kill you when your passing a car in third. It probably doesn't make any more power but it makes the bike sound mean and nasty! sorry I'm off topic... Mark lets meet up sometime and ride. My buddy down the street has a 99 cyclone M2 and his dad has a new XB12.... | ||

I suspect you'll find that with a stock filter and stock map just putting a slip on exhaust won't unduly impact the riding experience. But the bikes run on the lean side when standard and with the stock muffler. Most of the aftermarket ones will actually make that lean running worse. So whilst it might "feel" OK you'll be running the bike even more lean than it was designed to do. That'll have an impact on the running temperature and potentially the longevity of the motor.. The bolt-on "fuel mapping" devices that you're looking at really just add extra fuel, normally across the entire map so they'll mask the problem rather than resolve it. They're probably "OK" but you won't be making most use of the potential gains...but theoretically they will fix a lean running issue introduced by the slip-on. | ||

De-noid is definately one of the first things to do.. Although when I went to do mine I found the dealer hadn't actually fitted the cable to the TB so it was "unneccessary" but being as I was in that area anyway I went ahead and removed it and fitted the resistor plug. | ||

I agree with Jules saying that the Piggy-back systems just mask the issue and not solve it. Personally I would save some cash and have the lean issue fixed by changing the map inside the computer then you could run any filter/exhaust combo you wanted and not have to worry about melting a piston |
