OK, i know on the CBR forums the guide states to have jets 1 step up in cylinder's #2 & #3 to run them a bit richer and therefore cools them. This makes sense...
I recently jetted my FZR250R but my stock Jets are 100s on cylinder's #1 & #4 and 97.5 on #2 & #3.. completely opposite the the CBR. Would this have anything to do with the fuel feed from the pump coming in between #2 & #3 first therefore their already richer?
I've already put 112s on the outside and 110s in the middle's but can't test it as the bike is still in pieces undergoing a rebuild and complete fairing repair and respray. Kinda just wanna know if it sounds rights before I put it all back together as i don't wanna damage my paint job removing stuff again.. its been in pieces in my garage for like 3 months :(
On a side note, are 112/110 enough for the below mods:
- Custom foam filter mod
- modified/hacked airbox
- straight through muffler
Because for the same mods the CBR guys used 115 but their stock jets are also 1 step bigger so i just did some backwards maths
