Default Y2K Curvy Jetting - Anyone have similar?

Hi all

Looking for a base jetting kit for the following:-

2000 SV650 with the following fitted:-

Pointy inlet cam / Curvy inlet cam in Exhaust
Standard downpipes but race can ( ART Oval Carbon)
K&N Filter.

Had it on the Dyno witout the cams and it's running lean throughout the range, I would like to try and get the jetting much closer with the cams fitted as the dyno isn't free again until mid may.

Any pointers from someone who has a carby, with the cams / filter and pipe would be great

Thanks

Jim

I did the cams, devil system on my bike (2001) and had it dynoed on base settings for carbs (not sure what but i THINK they are stock) and it ran at 79.1 rear wheel hp.

I then put my K&N filter in and the bike barely ran. So i took it out again and left it as it was.

Well thats because it needs jetting, even with a devil system and cams it still should require jetting and it's breathing more.

K&N would take it over the top into really lean teretory, get it jetted with the K&N in and you will see an improved performance.

Just saying i haven't opened the carb yet. its something i might do once ive sorted my suspension out. That is how it ran on dyno with pipe, and cams, i decided to leave it at that for now as its not a race bike and it was the most powerful SV they had had on their dyno so far (out of around 8 i think)

Hi All

OK here is the graph of mixture from the SV with the K&N and ART Can

Looks like the main is at 14, and needle about 13.6 and the idle about 15

Any pointers on jetting to correct this please?
