Hi Pratik,

It really is worth doing the tuning yourself. It can take a bit of time, and a lot of test riding (change jets, test ride for a day or two - or a week - change jets again, test ride again etc.).

I was completely new to motorcycles, and mechanics, about a year a go. I found tuning the carb to be a very satisfying (and exciting) experience. I also learned a lot about the bike along the way.

The key is to do lots of research first. There is a ton of information dispersed throughout this forum.

Here is a link to get you started. I think this is the best summary of carb tuning I've read on here.

I'll post some more links in this thread over the weekend - when I drop into the forum from time to time.

A couple of quick points:

1. You'll need to find out what jets are in the carb at the moment. The previous owner may have changed them

2. Is the muffler you installed an open pipe, or does it have a baffle? Open pipes present their own specific challenges for carb tuning.

3. If the muffler is open, or nearly open, you will most likely need to tend to the intake on the carb, using a more open air filter.

Oh, and welcome

I will tell you what I was told about backfiring, Don't ''snap'' the throttle off when shifting, ROLL it off some to shift but not all the way. With a little practice you can stop backfires while shifting just by changing your wrist ''programming''. After a while it will become automatic.
And you are not riding a multi cylinder bike, if you try to use heavy engine braking to slow down with a big single you WILL get backfires, some bad enough to damage your muffler's baffles. That is one of the ''blessings'' of big singles and is VERY hard to get rid of totally.
Ride more, worry less! A S-40 has a ''personalty'' and the best way to learn more about it is MORE MILES!
What do you mean guys to ride with this summer?
Local, medium distance, or long distance?
And what is a long ride for you, 100, 300, or 1000 miles?
There are a couple of rides coming up in western NC, and north GA that will be fun. And you can trailer your bike there, or close. Unless you are experienced at long rides to a campground trailering can be better as you can carry more ''stuff''.
Meantime just ride, clean, and get to know your new bike. (Cleaning is important for a new bike rider combo as you will be checking things over as you clean. Look for loose ''things'', oil leaks, marks that weren't there before, and fluid levels and tire pressures. Learn your bikes ''normal'' patterns and then something ''abnormal'' will stand out to you.)

Late model Savages are jetted lean from the factory.
Your new muffler is gonna require you to rejet, bet on it..
It's not technically difficult. Getting the bowl off is not usually easy.
Start drizzling penetrating oil on the four screws now. And get a No Kidding, real,
JIS screwdriver. If you have a battery powered or air powered impact, that is helpful. A handheld, hammer impact is begging to break the carburetor.

It's probably gonna blue the pipe if you don't get it running richer.
If you can feel the loss in power, it's a good bit leaner. That's not healthy for the motor

Elevation for My place is 85 feet. If someone can give me instruction for get it run richer and also replacement jet size pls.

Thank You.

Got it Mr. Gary. May I know where you from in NJ if you don't mind?
