How many RPM are you turning in top gear at top speed? If you're not red lined, your engine is not pulling the gearing. You may be overgeared. You an try dropping to a 15 on the front. It's cheaper to change the front gear. See what it does. It may peak but at a slower speed. Then again,it depends on how many RPM you pick up. You could bring the gearing into a range where the engine can now pull the gear and actually increase the top speed of the bike by dropping down a gear. I've seen it happen many time. If not, you'll have to do something to get the power of the engine up.

Good Luck

Burns to much gas

my similar problem on 4 cyl jeep was cured by replacing both O2 sensors and coolant temp sensor (for second time). Also problem seemed to be related to putting too much oil on spector air filter and using carb cleaner which appeared to foul O2 sensors (a second time). replace sensors O2 sensors a 2nd time, stopped carb cleaner and now wipe off excess air filter oil and let dry in sun, and fuel economy went back up to 75-80+ miles per 1/4 tank of gas (vs. 55-60 miles per 1/4 tank of gas with fouled sensors).

06 Fatboy Engine abruptly dies at idle, and hiccups at highway speeds.

This sounds stupid I know... but change out the spark plugs and stay with the standard plug, no platnium or irradium plugs.

Jeep wrangler is using too much gas

I have a 4cyl 97 jeep wrangler. My fuel economy went from 75-80 miles per 1/4 tank to 55-60 miles per 1/4 tank of gas. I traced this to a bad coolant temp sensor (replace twice), and fouled O2 sensors believed caused by my self by placing too much oil on spector air filter (now wipe off excess and let dry in sun), and using carb cleaner and or gas treatment (stopped using). fuel economy went back up to 75-85 miles per 1/4 tank. (also disruption of sensor input/output signals didn't help from battery sliding into computer wiring harness, which I cured by placing a 1" spacer on rear clamp to keep battery away from computer.)

Jaguar XJ 6 - 3.2 Auto-1997 P Reg. When the engine is cold very slight engine miss at idling speed which goes off atfer 2-3 miles Diagnostic test done. Changed one fuel injector and full service carried...

Try running a good fuel system cleaner through it. LOTS of questionable fuel going around these days. Consider running cleaner every other month to keep system clean.

95 wrangler yj. has no power at high speeds

Have you had fuel pressure tested, and/or filter changed. Have you checked for plugged exhaust, such as catalytic converter? Quite often engine will also run a little hotter than normal when exhaust is plugged.

94 yamaha xj 600 wont rev over 6000 rpm

You bike is running rich on the main jet. Go down on the main jet size. Alternate to that, move the jet needle clip up one notch.

Go to the site below and you can download a free PDF service manual and parts manual for your bike. The service manual is 45th from the bottom of the Yamaha listings and the parts manual is 19th from the top. Now you can tune the carb and adjust the timing chain slack and a whole lot more. It saves my keystroke finger a lot of work also.

Please rate this solution. Thanks glouellette!
