Has anyone used them?

They do have wide range of Solex Cisac jets and almost every other parts readily available...

I was just thinking of ordering few jets from there if can't find elsewhere, just delivery costs might be quite high...

Jani, I'm no expert on carb tuning, its a bit of a mystery to me, but IIRC you were saying that fairly high throttle was kinda OK, it was light throttle and part throttle that was poor.

If that's the case, I wouldn't look to changing the jet sizes tbh, but see what emulsion tubes you have and look to changing for a slightly richer one and see how that helps.

Main jets only change overall fuelling. My guess is that its a progression issue, with the new cam, although possibly you might want to go up 1 jet size on mains too cos the K draws more, although tbh, if its working well on full throttle and also on 2/3rds then I would leave the mains well alone.

I'll stop before I start rambling

I posted few questions to my solex and idiot thread

If I order from that shop, then I will order also emulsion tubes, I think there was those with different rating too so I can swap many parts and make all really well messed up
