Air Filter

Postby flatwing » Thu Sep 17, 2009 3:50 pm



Hey Guys, Quick Question. Is It possible that A Clogged Air Filter Could Cause A Bike To Lose Top End & Horsepower? I Changed mine Yesterday After having Some loss Of power Climbing Hills & hammerin Noise! I took a Quick test Ride Today In between Showers. It appears To have cured the Hammerin & Has More Power!! Quite A bit more & it sounds Different! Sorry, For possibly A Dumb Question! :shock:

Thanks In advance

Yes a dirty filter will cause your bike to loose power and knock.
I like the foam uni filters....... :mrgreen:

Ok Guys, I Need Your help! I have A 1984 1200 Aspencade W/ 71k Miles on it.
My problem Is When I'm running along In OD 65-70 Mph, I come To steep incline Holding steady Throttle I Lose 10-11 Mph by The time I'm To the top! If I try & increase Throttle It acts like Its Giving me All It has! It won't Increase Mph & If I Hold My Head Down close to tank I Hear Noise Sounds Like Someone Playing drums On a tin Can!

Here Is what I have done to correct problem w/ Out It helping Much!
I switched To 87 octane. I Replaced Spark Plugs, Air Filter& fuel filter! It has A 2 year Old Fuel Pump per P.O.
Also P.O. Says He Rode 2 up All the time, No Problems!
Please Help! I've About Decided I Bought a dog!! I've owned About 3 weeks.

Thanks In advance
James

Mine turned out to be spark plugs. Replaced with NGK's with correct gaps and its a totally different bike now.

Flatwing, is the spark ok? You said that you changed out plugs, but have you checked the spark from each wire? Measure the resistance on the wires?

Flatwing, what RPM are you seeing when the bike slows down on a "steep incline"??

The reason I'm asking about RPM, maybe you just need to gear down one or two gears? I'm not trying to be a smart alec..just sounds like the engine is working too hard? :?

No Problem Bladerunner9,
When I Gear Down To Fourth, It Helps But Still can't Pick-up Speed very Fast.
Shouldn't These 1200 Be able to climb Hills If Your running 70-75 When U Hit Them?
Thanks All

Flatwing, Ive just recently learned that the project bike I currently have, a GL1100 was only running on two cylinders. I replaced the plugs and it seemed to work okay for a bit, but I checked the left side plugs and they were fouled only after less than 100 miles. Apparently, this bike sat for a number of years and Im now in the process of going through the carbs. Shellac is everywhere so far. I turned over the bike with the left side plugs out and she shot a geyser of gasoline out of both holes. I just dont think thats normal ;)

Hopefully today, rather tonight, I can get everything back together and see if the cylinders start to fire once again.

No rebuild kit, as time is diminishing for rides and Id like to get it out on the road for a couple of weeks. I plan on rebuilding all 4 carbs with akit this winter, in my "spare time".

I havent worked on a carb in decades, but with the stuff that Ive found online, its making it interesting and fun again.

All 4 cylinders are firing and whoa...what a difference. She purrs now, doesnt backfire and has a lot of pickup.

I think that this winter, Im going to get the Randakks carb kit and do her justice, but for now, I just wanna ride!

Good luck flatwing!

Make sure you check the vacuum hoses forward of the airbox. If they are not secure or need replaced, this will cause loss of power, and also on mine a backfire at de-cel.
