savage carb upgrade
11/04/05 at 21:15:30
 
hey all,, newbie on this site because i just aquired a "95" model savage. very good shape but needs a little wrenching that will happen this winter, first thing i notice is the CVK carb. most experience i have with these to date is simply putting a mikuni,sudco bank, etc in its place to cure the lean condition wich its likely to have. i have been down that road trying to buy needles,jets,springs,shut-off kits to make the CVK work and i wont do it anymore, because the truth of the matter is it cost as much as a new carb by the time your done when you count legwork and phone calls etc. before i get into my stock of carbs and grab a mikuni or something else i want to hear from people who have made the change already, its to cold out already to ride the bike so i have no reference on stock performance. thats where the forum can help me make up my mind to upgrade it this winter or not.

Welcome aboard!  If you're trying to tune the stock carb, please take a peek at the posts on carbs and idle mixtures in the Technical Documents/Reference forum but please don't post there.  Post any questions in this forum.  I would highly suggest doing a few searches on white spacer and rejet and do some reading.  Most people get pretty good results with a white spacer mod and rejetting combined with an air filter and exhaust upgrade.  If you are looking to replace your carb, shoot Lancer a PM and see what he may be able to offer or suggest.  He plays with, tests, and builds carb kits for the Savage/S40.

You rang??

Thanks for the "promo" Rob!

Charlie, you have raised the right questions on this issue.  An old cv carb can easily cost as much or more to rebuild/fix than to replace it with a new performance carb.  But you do not know for sure until you take it apart, clean and check all of its parts.  I have done quite a few, some end up working fine and others have resulted in some unknown "carb demon" that simply refused to be found...the answer to that situation was always a BIG HAMMER...I HAVE NEVER FOUND A CARB DEMON THAT COULD SURVIVE A SLEDGE HAMMER...always works the first time!!!

This past year I have sold rebuilt Edelbrock Quicksilvers,  and new Amal Mark II's and Mikuni VM's.  I would like to try a Dellorto but have not had the opportunity yet.  I am out of all the Amal's except for one lone 34mm.  It is a bit small for the Savage for top performance but would have good low/midrange.  We usually use the 36mm VM for a stock Savage and the 38mm VM for a modified engine.
The bare minimum for a carb swap is carb/mounting flange/throttle cable, which runs about $200 with shipping.  If  you want to do the "FULL MONTY", the whole kit is $295 + shp.
I have them listed on Ebay  "Suzuki Savage Performanace Carburetor Kit"

ftp]http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1&item=4585837211&ssPageName=STRK:MESE:IT[/ftp]

If you have carb questions I would be happy to TRY to answer them.  There are a lot of folks on this site who can answer virtually any question about any part of the Savage...and do so with gusto!  Welcome aboard.

I have the 38mm Amal from Lancer, and can attest that you get A LOT more power and range, especially at higher RPMs.  And, no backfiring!!!

I'm currently bidding on...
- a 35mm Dell'Orto double barrel  Shocked
- a 36mm Dell'Orto motorcycle          Smiley
- a 37mm Mikuni from a GN400     Smiley       ,
and I'm watching a few more (including a 40mm Mikuni CV but it doesnt look very clean) Tongue

Something will have to work.

What should I use as the final connection between the carb and the head? Metal headers are specced to engine/carb specs, but once I customize...
any ideas  ???

Most performance carburetors require a change in the mounting flange on the Savage.  I use 3 different sizes, depending on the carb to be used, for mounting on the Savage.   I am a Sudco dealer and get mine from them.  If you need to know which one to use for a particular carb give me a shout.  I will need to know the OD (outside diameter) of the carb, on the engine side.

Right, will do.
I'm actually daydreaming about the Dell'Orto double barrel, with forced air induction, a reworked head, a heavier flywheel and ... too bad I can't change the gearbox like on Harleys and the old English bikes... Grin

It'' probably remain a 'plain old cruiser', although I am a glutton for wolves in sheep's clothing  Wink

mpescatori,

A heavier flywheel?  Why?  Will this make it run smoother?  A gearhead friend of mine suggested that the flywheel could be lightened to hot-rod it (not realizing I was talking about a single).

In the old Go Kart days we used to use a 2 1/2 hp flywheel in a 5 hp engine ( much smaller and lighter) to make them quicker and faster and they are a 1 cylinder..

When I got my FCR from Allens Performance (UK) they made a screw in spigot for the carb that fitted the standard mounting rubber.

Your comment is not wrong, but there are buts.
A lighter flywheel is OK for 4+ cylinder engines, as they rev very very high and the flywheel is sometimes needed only for the starter motor and to smooth out at idling. However on a big single a lighter flywheel would make idle lumpier and at high revs it could actually be prone to more vibrations.
A heavier flywheel, on the other hand, would make idle much smoother, would imply less rev drop (c/o piston compression etc.) at gear changes and much more engine brake when downshifting. If one is to cruise on a perky engine, rather than lap around a circuit, I'd go for a heavier flywheel.
Actually many modern singles have one flywheel AND two smaller flywheels that rotate in the other direction !

Anyway, weren't we talking about carbs  Wink
