Full Version: Jetting Question for HRC Kit
Quick question to all you jetting gurus out there. My 450 already has the unlidded box and K&N type filter, an un-corked stock exhaust and stock cap on it with a 190 main jet in it. I purchased the HRC kit really cheap online (mainly for the endcap and cam) and istalled the HRC cap and by the end of the week hope to have the cam in. My question is should I leave the 190 in it with the unlidded box or should I put the 185 HRC jet and needle in it with the HRC lid. I can't find any thing on the needle except it says C55D on it and the HRC needle says C51B. Can't find any info on Kehin needle markings to see if the taper matches the 190 or if it is a stock needle. thanks in advance.

190 is way too big, try a 175 - 180
