01 TE 570 jetting Q

Recommended Posts

hi all,

 

Been off of my bike and TTicon1.png for a while.  Have an 01 570 and doing a rebuild of carb.  The problems are many after sitting for two years.  I have had it running but not well the last few weeks thus the rebuild. 

 

Here are my jet sizes;

Starting jet - 60

idle jet - 57

main jet - 162

needle jet - AB264

needle valve - 300

needle - K32

 

Riding in Nevada approx. 4600' elevation.

 

The body is getting a full sonic bath tomorrow and fresh screens and gaskets all the way around.  The bikeicon1.png was flat on full throttle on the last few rides after a local mechanic "tuned" the carb to try to resolve the performance issues.

 

I am prepared to adjust/jet until it is runninglb_icon1.png perfect so I am looking for some experience and a starting point.

 

Lastly a big shot out to the guys I rode with in Baja a few years ago, Steny, George, his boy and all the others.

here are my thoughts...pilot jet too big for that elevation.float valve due for a change out unless recently done.the k32 needle may be worn,the ab 264 needle jet may also be worn.is your manifold cracking?is your flywheel magnets coming apart?dan

Hi,

 are you 100% sure you are getting enough fuel to the carb,

 

 the 570 / 610 need LOTS of fuel at high rev's,

The carb body is getting a sonic bath today and some glassing to get some crud out of the bowl. Replacing most of the parts that can wear I.e. needle and jets.

I haven't opened the case to inspect the flywheel. The clutch is tight and works well. I am replacing the floats. I received an education on the importance of floats and float setting this morning.

I'll replace the parts mentioned Charlie. Thanks guys. A couple of the o rings were shot and the guy who worked on it last sealed the throttle cable cap with gasket maker.

Soon as its done I'll post some pics.

Ok I had the body, banjo, choke body, bowl and bowl nut ultrasonically cleaned.  I took it to a local carb guy Competition Carburetor.  He builds race carburetors and ships all over the country.  He used a cav tank.  The results were amazing. 

 

Got a Delorto carb kit from Bevel Ducati in Concord Ca. 

 

After cleaning everything and rebuilding the results.......AMAZING.  Bike kicked over first time!  After some tuning I headed up the mountain.  WOW.

norman foley has always said as long as it's clean a dellorto IS the best carb on a left kicker,

 

your bike looks great ! well worth the effort ; . }  never seen a steering damper on a left kicker before..!!,
