A few things about 2001 SV650S

[kenny]

any info on these:

iridium spark plugs, are cr8eix the correct ones to use.

the standard jet sizes i think the last owner rejetted it up because it had a aftermarket exhaust on it then removed it and replaced the with the standard system when they sold it so now its lumpy on the tick over.

Thanks,
KeNNy

cr8eix is the correct plug although cr9eix is slightly harder and MAY be better for the summer.

Don 't know standard sizes but I found this on the net at https://www.geocities.com/catpoopman/sv650_rejet.html

Jetting Info:



Pilots: 17.5
Main Jets: 137.5-140 (for stock exhaust)
140-145 (with aftermarket exhaust)
Needle: 2 shims under clip
Air/fuel screws: 2-3 turns (2.5 seems good for most)
Float: make even to leanest float. (if you even check it)

Jack Roe's multiple dyno runs showed an aftermarket full exhaust and stock filter worked best with: 140 mains, 17,5 pilot, 2-1/2 turns and 2 shims. Read the whole article HERE.

My current setup: desnorkled, full race exhaust 152.5 mains, 17.5 pilot, 2-1/2 turns, 2 shims, and a drilled slide hole.

Another good setup is desnorkeled, full exhaust 152.5 mains, 17.5 pilot, 2 1/2 turns, 2 shims.

Your setup could be different depending on type of exhaust, air filter, altitude and other mods. Trust your butt but stay close to the recomendations you see here.

Here's the standard jet sizes (UK):

Pilot 17.5
Main 137.5
Pilot screw 2.5 turns out from full in
Float height 7mm
Fuel level 17mm
E-clip should be on second groove, with only the spacer underneath

You must also realise that the information given on the above link is for a Californian model SV, and therefore the jetting/needle position will probably need to be different for UK.

Some people also talk about using a slightly larger main jet on the front carb as the front cyclinder block is a slightly lower temperature than the rear. Whether this is a good idea or not, I don't know, but a 140 front/137.5 rear is not uncommon.
