I am now the proud owner of a Sabre butnhave some issues bike is a 03 when I picked up from dealership was cold like 35 degrees and bike had a stutter coming off idle figured it was just cold after riding for about a hour it’s still doing it.it has Vance and Hines longs shots with baffles removed and stock air box.bike has been jetted already but not sure if they took the baffles about before jetting or after dealer said the stutter was there because if temperature outside had kind of a random lean pop anyone sure of this weather being a problem or is it possible carbs need synced i ride all year long so trying to figure this out.thanks to all in advance

You might try turning the mixture screws out a little. They’re covered with plugs you’ll need to remove first.

2-1/2 to three is what I usually go with and if it’s over 4 4-1/2 then Jets. The rear jets are larger on Sabres cooling rear cylinder I think. Mine is so far out of stock at this point IDK

I found the problem they put a nipple on the intake to run a fake hyper charger I removed it and put a cap on it some how the cap came off creating a vacuum leak was gonna hook my vacuum gauges to check the balance on the carbs when I found it lol thanks for all the help

Yeah I think the stock jetting on the Sabre is supposed to be 175 and 180 for the mains - when I had to take my carbs out I found that they had actually been jetted smaller... with open baffle V&H longshots... go figure, but she ran real good before she didn't. If you don't have to take them out, don't. But if you do, you can pull them out the side. I found that easier than out the top like the manual says.

Yeah it is super loud for a Honda, but to me it sounds really good given the engine design. No it will never be as burbully as a Harley, or as deep - but it also won't bleed oil and cash... The nice thing about aftermarket exhausts is that they are for the most part designed to have the baffled removed or installed. The stock ones you have to hack and drill at, which is where you can get into trouble if you don't know or don't care what you're doing.

I like the Harley’s but I like my Honda better plus the guys around my area wear skinny jeans and Oakley’s ride Harley’s and act like there better than everyone that’s just my area but the Harley guys haven’t got to good of a rep in my area lol

The issue may be that Dynojet uses a tapered needle design so the jets are sized slightly smaller than the stock Keihin jets. So lets say what you found was a Dynojet 170. It seems smaller than stock bit is actually equivalent to Keihin 190.

I checked, they are all Keihin jets - but it's got aftermarket needles that were shimmed, so who knows. Tuning carbs takes some serious trial and error.

As I was typing my previous post (#15) I was thinking no one mixes needles and jets right? :eek:
The horror! The horror! (-:

It happens, my bike has Dynojet jet needles and Keihin jets.
At some point I got frustrated with the proprietary sizing of Dynojet mains and the lack of local availability of their stuff except in kits and I got rid of them and converted back to Keihin sizes.
When I need a size that is not in my box I can now find suitable jets at just about any place that sells/services Japanese motorcycles or snowmobiles.
I've been buying EBC jets lately and they seem accurate to the Keihin sizing.
