i have a 84 v65, it runs fine it just doesnt get very good mileage, my brother in law has one just like it and his gets much better mileage. i have put new air filter, checked spark plugs, they look fine, not black like its running rich. its only getting about 27 mpg.. any sugestions?
how are you computing the gas mileage?
Are you judging it off a "gas light"?
My gas light is very sensitive. It'll come on at 80 miles, but I can go to about 150 miles before I need to fill up.
Do you have a reserve?
How are you hitting that throttle?
If I ram it constantly, my mpg drops to about 35, if i nurse it, I can maintain 50/51 mpg!
Have your valves been adjusted? Carbs cleaned/rebuilt? How's compression?
i dont go by the light, i figure it by how many miles i have been and how much fuel it takes to refill, as far as the trottle, i try to baby it, keeping under 70mph, not hitting the trottle hard, carbs have just been cleaned,rebuilt,and syncronized, compression, is good. one thing,, this bike is a california bike, i have taken the charcoal canister off and plugged the lines, that might have something to do with it i dont know..
Yeah. I personally don't have a v65 but our bikes are very similar. Hopefully, a more wiser member can lend more assistance.
I just now when I hit it hard ...i average like 40 mpg...but if I always kick it into the highest gear, and never use my brakes....i hit 50mpg +
Got some place you can take it out and blow the soot out of it? A little Sea Foam a couple of hours of hard riding, getting the rpms up in the 7 to 9 K range as often as you can will do wonders.. Mine runs like a sick calf if all I do is ease around town and never get the rpms up, I try to get mine out on the superslab occasionally just to blow the cobb webs out, I ride a 3rd gen 750, and the V-65's are built for higher speeds than mine. I usually average about 50 mpg. Hope you get your problem solved ..
I am riding a 1986 V65 and check the mileage every tank and it ranges from the low 40's to as high as 50. I average mid 40's. I ride it work which is 40 miles each way with some city driving included. I don't baby it through the gears and on the highway stretch speed is 70 plus mph just keeping up with the traffic. I have read that these bikes were made for the higher rpms. Mine runs smother above 4000 rpms. Also mine is not the Calif. model. I have a KN filter use reg gas sometimes plus and my exhaust has no baffles in them. Just my 2 cents worth.
