Title: power loss after highway cruise
Post by nateordie on 05/29/13 at 01:16:00

If anyone can help I'd appreciate it.  So I was riding on the freeway the other day and I had to pass a car to switch lanes so I gave it more throttle to pass picking the speed up to around 85.  I held it there for about 20-30 seconds and then passed the car and went back down to 70.  When I exited the freeway and got to the stop light it felt like my engine was dying.  I know it wasn't out of gas cuz I literally filled it up right before I got on the freeway.  Anyway the light turned green and then I had to give the bike about twice as much throttle as normal in order for it to accelerate.  It just felt really dead and unresponsive.  As if the engine went from a 650 to a 250.  I got home and shut it off and that night about 5 hrs later I took it for a test ride.  It was hard starting at first and it seemed a little weak in power but after 5 mins it seemed back to normal.  Now it runs fine but I hear something like a faint buzzing noise coming from the left side of the engine.  Can anyone make sense of what happened? Thanks.

Check your oil level in the sump  :-X

85mph on the Savage is more than light speed... more like "ludicrous speed".

30 seconds at WOT at full revs WILL be taxing on an air cooled single...  :-/

Really... 85?   ;D  don't ask,  :-X  don't tell... just grin   ;D

usually, that's outtadoor speed.  but I do manage it in the morning ocassionally.   ;D  everybody notices when mr excite walks in.   ;D

will hurt your bike? don't think so.  But you probably have some jetsome, or flotsome swimming around in your carb that got aggitated and sucked up into a jet.  I'd drop the bowl and remove the slide, spray some carb cleaner, dislodge the dead cats, blow out the air filter and drain the airbox.

Do you still have a stock petcock on that bike?  Some people have had problems with the diaphram going bad, and causing the bike to act wierd!!

When you gave it more throttle, did it go up in rpm though?

Wait, what?? I commute daily on the freeway and periodically am at this speed for 2-15 minutes. Is that damaging my engine? :o :o

IMHO, any time an engine is pressed beyond about 80% of its max its causing wear at a higher rate. Short bursts are no big deal, but extended operation at higher than 80% of max is just hurtful. That the crank & rod are on rollers is a good thing I think,

Yes it did go higher rpms.  It felt like I had to give it gas to keep it alive.
