Z400Gramps.. Your responses are so humorous.. Change the Damn gas!!
I feel like I'm talking to my dad... no offense..
I think you solved my problem though..
I'm on the 4 clip down from the bottom.. However I wasn't aware that the nylon spacer goes under the clip.. I didn't get any instructions with my jet kit from Alba.. i just got the kit.. So... Tell me what you think..
I'm going to put my jet needle on the third clip from the top or right in the middle for the most part and put the nylon spacer under the clip and see if that makes a difference.. That has to be a really lean spot in the range.. You know and I could tell, and I even raised the needle up some more to give it more gas, but I thought the new needle completely replaced the stock setup....So missing that spacer is why i'm running so lean from 1/4 throttle to 3/4 throttle.. my plug is checking fine though.. That just goes to show plug checks aren't always accurate.. Rich on the bottom, lean in the middle and rich on top will yield a good plug reading. However will not mean your bike is running up to par..
To address the filter issue.. I have a stock replacement Uni.. I removed the Snorkle, and added the vents in the top of the box and I'm getting mad airflow.. This setup is getting me plenty of air.. Besides I have to keep my lid on.. I tried to find a median between no lid and a lid.
Thanks..I'll make this change tonight and post you guys on the differences.. It is going to be in the teens tonight here, so I'm going to be one cold .......... Thanks Gramps..LOL
