Title: Jets again! Places to buy
Post by: 90GS500rehab on July 15, 2003, 03:03:33 PM
Has anyone heard of this place?

http://www.motorcyclecarbs.com/mikuni/mik_tuning.htm

Also which are the correct jets? Looks like N100.604 is the correct main but the description of N102.221- fits it better.

For pilot N151.067- Non-Bleed looks right?

Anyone got input on this? My carbs aren't here so I can't hold them up to the screen lol.

No one around here carries jets and they all will charge me more than ordering online for "special order".

Thanks

Assuming you have a pre-2001,  N100.604 is the correct main, and N151.067 the correct pilot. I don't know about post-2001.
See my rejetting page (http://www.angelfire.com/mt2/mikesgs500/rejetting/) for detailed pictures. Those prices are rather high. You can get mains for $2.50 from the parts unlimited catalog.

BTW, thanks for the link on the ds650 site. Finally a good explanation of the difference btw Dinojet and Mikuni jet sizes.

OK I dont believe that info is accurate on the correlation between DJ and mikuni. Atleast not in the GS jet kits. And AKAIK...DJ dont make 145's or any 5's for that matter. DJ flow control in the GS kit is entirely dependent on the needle. Their recomended stage 1 is a 118 or 122 (or 124) which has the same diameter as the mikuni 122.5. The DJ mains dont add flow. In fact there was this guy on the old and now parallel BBS that just put the needles in and that seemed to cure all his woes except the very low end which actually he was able to air screw to where it was OK. I hadn't seen the DJ jets then but now I know why. Its like going up 3-5 jet sizes up in the top end, and 2-3 in the midrange and -1 right at the bottom. I was surprised he didn't go too rich but he probably was super lean at the start. Dunno about the Vmax but 122.5 mikuni and 122 DJ's are the same hole dia. Of course the internal profile could alter flow a bit but I cant see any real diff. The DJ jets are also smaller in their head dia and that could affect flow also but again I dont see any significant reason why it should.
Cool.
