Reving High With Low(er) Power

[ledofthezep]

Bike runs great in all the other rev ranges. no bogging no hesitation just giving up in the high revs.

 

Not trying to sound stupid or anything,...but have you ever replaced the stock clutch? Mine did that too a bit,...I just lived with it for a while & it ended up being the clutch slipping. I couldn't believe the difference after replacing the clutch. Just a thought.

I bought mains today

ranging from 300 to 360,

 

330 sounds good! ill try that Benbb

 

Nah the clutch isnt slipping, but a new clutch is on my wishlist.

alot is

 

Need new tires first.

Going for the Titan fast trekkers, look nice and i think they will do pretty good allround. (trials) (construction sites with mud and sand).

 

Upping the compression.. hmm i still have a stock crank (unwelded),

I dont want to pound it much more since i read alot about the seperating crank issue..

125 psi at sea level is pretty good. this test was done with cold engine throttle wide open.

I'll do a retest when my engine is warmed up.

Anybody happen to know the stock dome size on a banshee?

My guess would be 22cc.

I found a nice head on alba for about 85$ its already milled but the dome size is not mentioned.

Went out for a ride yesterday,

Am still using the 340's with the drilled airbox cap.

 

The wheater was a bitch. it rained all day,

But the banshee drove fine all day, except for the bald tires,

and some white smoke now and then.

i checked my radiator but i couldnt see any bubbles so i figured it was ok.

 

After a whole day of driving, we washed the quads, and did the usual maintainance.

Turns out that the holes in the airbox cap had been passing water all day.

My airbox had a descent amount of water in it.

and i think this is also where the white smoke has been comming from!

 

I drained the airbox dry and removed the filter,

the filter was feeling wet,

Using a flash lite i saw a white fluid in my airbox boots,

oil+water = white fluid.

 

Since the banshee drove fine all day, i dont think much water passed through.

But what can the damage be?

Should i be affraid me crank bearings go?

 

The airbox cap with holes isnt such a good idea.

As a little test i drove without the airbox cap when the road was dry.

The banshee ran even better.

 

i'm left with 2 options:

go back to 300 mains and use the airbox cap without holes.

 

or keep the 340 mains buy a knn filter + adapter plate,

and use outerwear to keep the water out.

 

Is the outerwear really water proof?

Cut the end of the lid off, just 1.5" right behind the clips so you still have all four clips.....the cover will still protect the air filter....A K&N w/ flange and outware would also be a good idea.....cover the holes on top w/ rubber plugs or plastic pop ins...

Thanks Banchetta,

 

I dont think the engine suffered any damage,

Ive got an mp3 of the banshee flying trough its revs with 2 peeps on it.

(me recording, cousin driving)

This recording was made after water in the airbox.

sounds good.

but should i check something anyways?
