[dsn_klr650] octane rating.......cylinder out of round...

[k650]

When you lay down on the tank as in your example there is less wind resistance than sitting upright which acts like a parachute putting more load on the clutch which if the disks are worn, springs weakened or just the cable being misadjusted can be just enough to cause slippage of the clutch needing more engine RPM to maintain the same speed as when there is less wind resistance achieved by laying down on the tank. In short slipping the clutch changes your gearing. Walt

How about wind resistance .... Last time I checked moving through the air creates a certain amount of drag based on the size of the object. This drag slows you down .... Why aren't Moto GP riders sitting up on their bikes as they go down the straights - because they can go faster when on the tank. Pete

Agreed, IF you had a bad clutch. There was nothing wrong with this guys bike, and he was referring to all bikes when he made the claim. The guy was just a bull$# !tter. Always was always will be. Rick A17

Years ago I had an XS650 with a weak clutch that behaved in a somewhat similar manner. In 5th gear beyond X RPM at highway speed you gained no acceleration if you hit the throttle hard. You could creeeep up your top speed, but past a certain total load (of which wind resistance was a major component) the engine would turn faster but the clutch would not transmit the increased power to the rear wheel.

Yes, they can go faster, but that isn't what we are talking about. This guy was claiming for instance, that if you ride a bike at 55 mph, and the engine is turning 4,000 rpms, that you could lay down on the tank, and the bike would run 55 mph at 3,500 rpms Rick A17

Rick I 100% agree with ya. !! here is some info for you Walt: The octane rating is a measure of the resistance of gasolineand other fuelsto detonation(engine knocking) in spark-ignitioninternal combustion engines. High-performance engines typically have higher compression ratiosand are therefore more prone to detonation, so they require higher octane fuel. A lower-performance engine will not generally perform better with high-octane fuel, since the compression ratio is fixed by the engine design. The KLR has a 9.8:1 compression ratio. 10.:1 ratio is the level at which an engine becomes a high compression, therefore requiring 91 octane or higher fuel. I know my KLR does not ping with 91, but does with any octane lower. if your looking to save a few pennies at the pump.... buy a moped !! haha.. were talking about a 6 gallon tank. most of the time, you fuel up after reserve kicks in. so, 4.5 gallons of fuel thats 6 cents more... no problem.. -Mike- ----- Forwarded Message ---- From: k650 To: ramachm12@...; dsn_klr650@yahoogroups.com Sent: Thursday, April 9, 2009 1:55:10 PM Subject: Re: Fw: [DSN_KLR650] Cylinder out of round... Your bike is either set excessively lean or has large carbon deposits on the piston top, valves and head. I would try adjusting the mixture screw. You might lose an MPG or two but with the less expensive regular gas the cost per mile should still be less. Walt
