I know boss! We're glad to have ya! Haha, I was trying to detour the idea that your bike might have a PHYSICAL or MECHANICAL issue. I wasn't trying to be mean or condescending to him; just didn't want you taking unnecessary steps to fix it when it ain't broke! Ya know?!

What are you doing on here?! Go ride and run your tank down like I asked you to!

 

Lol im about to head out thanks again!

 

Good man! Be safe.

 

i skimmed threw and didn't see anyone post about sprocket change.. i had millage and running rich problem when i first got my f4i and it was the fpr..
after i swapped to the 600rr swing arm i changed my front sprocket to -1 so the chain would fit.. i noticed big difference in rpm on highway and millage went down a bit too.. i have read where people doing sprocket change to -1 in front and +2 on rear.. to me seems like you would waste more gas than it would be worth.. i have another chain and am going back to stock gearing.. i'm not a racer and the bike is fast enough on take off for me...

 

Nobody mentioned gearing because USUALLY the owner of the bike has done his research and knows what will happen with a gearing change, and the OP didn't mention anything about a sprocket(s) so I guess we ignored it. Good suggestion though!

PS- I agree. Stock gearing is just fine. With a sprocket change, you can't go on any long rides or enjoy a simple cruise the same way you can with stock sprockets haha.

 

Ok so yesterday I had the fuel reserve indicator come up at 146 miles. As a reminder, I've put 3.688 gallons before. I've also noticed quicker starts with the 87 octane gasoline.

 

What was the mpg for that tankful?

 

well, i only know that i was able to do 146 miles on 3.688 gallons, which would give me roughly 39.58 mpg. also, i've been trying to ride carefully not exceeding 5k in the city.

 

sorry if this is partly off the subject at hand...
I've been running 93 octane since i bought the bike (it's also what the PO said they ran). i know that one time i had to get gas the station only had 92. (I also realize the owner's manual says it's designed for 87). so, i figured 92 shouldn't make any noticeable difference, but the bike seemed to run really rough on it, so I've been afraid to run 87.

all that being said, i was wondering how response of the bike has been on 87 compared to 93??

 

here in CA we have 87, 89, and 91 octane fuel. i used to always get 91 until recently when i've switched to 87 and i notice a slight improvement in engine response and start up. hope this helps.
