I assume you are running the stock CV carb... except for jetting? Air leak more than likely!   Logged     The administrator has disabled public write access. #431564 Ratl (User) Time is just, priceless and it expires. Platinum Boarder Posts: 1102 Re:leaning out? 1 Year, 6 Months ago   I'm not saying this caused your sudden change of mileage. I'm pretty sure everyone is on the right track there with an air leak. However, while I know you said you cleaned the air filter, but if you have one of those OEM cheap paper filters that come with the bike, you might think about changing that out. They get clogged up and blowing them out doesn't work very well. They'll still restrict air flow, cutting down your milage. I was surprised at the difference when I changed mine out to a K & N. Just one less thing to worry about.   Logged     Some days you\'re the bug.

It will pick up the smallest of vacuume leak. When the engine increases rpm, that's the spot.   Logged     [img size=150][/img] Cooter Scooter 06 Roadstar   The administrator has disabled public write access. #445434 tristate (User) Senior Boarder Posts: 287 Re:leaning out? 1 Year, 5 Months ago   It doesnt make much sence, with a dj-160 it should have been way to lean from the very start,something else has happened, the equivilent mikuni is a 150,I am pretty sure I,ve never heard of running that small a main w/o problems, I went down 1 size from dj-190 to mikuni 172.5 very limited change. good luck.   Logged       The administrator has disabled public write access. #445436 JEastonjr (User) Drive for the greater good.

Its a long shot on that but it could have happend. I'll go with that cause everyone is saying your main is to lean anyhow. I know I was casing a air leak all summer and went thru H--L hunting it down. Turned out my exhaust valves are leaking.   Logged     feel free to look thru my albums email me at jasonwoody1982@yahoo.com my 2005 midnight 1700 ORIGINAL ROAD SLAMMER   The administrator has disabled public write access. #445527 texasscott1 (User) Two of a kind Platinum Boarder Posts: 2487 Re:leaning out? 1 Year, 5 Months ago   With the stock airbox and exhaust DJ actually recommends the 160 main for a 1600. If the bike is fairly old you might check the coasting enricher for cracks which would cause a vacuum leak. So, why do you think it's lean? It would help a lot if you would fill out your profile. Bike year, air filter type, exhaust type, jetting, etc.   Logged     My 99 Standard Test Mule Scott B.   The administrator has disabled public write access.
