Welcome JD ! Seems  it's up to me to say something to try to answer your questions. I'd jet for sea level ,you'll be running rich in Mt passes, but that's better than running the bike lean (hotter ) at sea level . from what I see (if correct) your header looks very blue and the carb could already need larger jets and the white spacer mod. Jets when installing an after market air cleaner and or the HD shorty will vary ,we'll need to know your elevation above sea level ,type of air cleaner ,and if the muffler is stock (baffled).
      I'm not to knowledgeable about Z-bars but I THINK 10 inches might be the limit.
      There are cast wheels that can be used from older Suzuki GS bikes, and there are companies that will lace our hubs to larger rims or provide the rims and spokes ,if you wish to do it yourself. Again I'm not the one to tell you . but you'd have to tell use what style you intend the bike to become.

There isn't a direct bolt on for the front.  the intruder has a 21" wheel but the disk isn't compatible.  but the intruder front end would swap.
For the rear, wouldn't recommend anything larger than 16" or 26" diameter as it wouldn't fit in the swingarm w/out a mod.
Get a jet kit from lancer and you'll have everything you'll need.
Then run thru the jetting instructions in the tech section.
Every bike is different and nobody rides like you.

I would lace up an 18" or 19" rear hoop.  If you keep the tire diameter at 26" and keep the stock shocks, you won't have to modify the swingarm or swap out the belt.  

I went skinny.  If you want to go wide you probably need to mod the swingarm to allow for a bigger tire or maybe go 17".   I don't know if anyone has gone 19" on our bikes, but you would need to stay really skinny.  Like old school skinny.

Avon makes 19" Roadrunner and Roadrider tyres that can be used both as front and rear rubber. They even have a racing compound if you have extra need for grip http://www.avonmotorsport.com/historic/motorcycle/am26---roadrider

The stock 100/90-19 tire is a pretty common size size - unless you are used to seeing the narrow 21" front wheels that a lot of choppers use. You can drop down to a 90/90-19 front tire if you want a smaller tire up front - but it won't fill the front fender up anymore.  I am not sure what tire your bike has on it now - but if the tires are the original IRC and are 22 years old....that could be what is throwing you out on the curves (the stock IRC tires are not very good).

For your chopper/bobber look - I really don't think you want to go to an 18" rear wheel.....that size rim works on Cafe' and Tracker and Traditional style motorcycles - it just doesn't fit the style of a chopper/bobber.  There are some vintage spoked wheels/hubs from Suzuki are 16" that will bolt onto the Savage - I don't know off the top of my head which ones (GS or GT bikes from the 70/80's) - the problem is that they are very narrow 2.15" rims which severely limits your tire choice, and it is very hard to find one that isn't all corroded and nasty.

There is a complete thread on tires for the Savage, and I will post a link at the end of this thread.  The Stock 140/80-15 rear tire is only made by a couple of companies and is hard to find.  If you want the best/quickest handling and want to keep the bike close to stock - a 130/90-15 tire is recommended.  If you want a bigger tire a 140/90-15 is significantly bigger and you have a lot of choices - it does slow the acceleration down, makes the bike a bit less eager to steer, and it is a larger diameter and helps cut down engine rpm when cruising.  It is about as big of a tire that you can fit without rubbing issues.

The stock airbox works well on this bike....if you can stand to keep it you will have a much easier time getting the bike jetted so that it runs well.  Cone filters don't always make your bike run better - and some make it run poorly.

Hey Guys,

The stock air box delete is for looks. Definitely want to use an intake or velocity stack on it. I just like the bare bones look. I love seeing the frame etc.,. I have rejetted many many carbs and been able to tune them with no issues.

Yes, this is going to be a cruiser. I have built my fair share of both choppers and cafe style bikes. The savage frame is perfectly set up for a bobber/chopper look.

I still haven’t been home to get the tire sizes. They are definitely not the original tires as they are fairly new. Not worried about front fender not being filled as it will be replaced with a better looking front fender.

I will be keeping all the stock parts to replace back on the bike when my girl is ready to ride.

I definitely need to figure out a seat situation. For some reason while riding the stock seat forces you forward into an uncomfortable position. I don’t want to modify the frame as I want to be able to put the bike back to stock someday.

Just ordered some 10” z’s. Looking at different muffler set ups. I’ll post up some pics of the progress as I go.

Thanks for the help guys,

SAVAGEJD
