SLP Pipes on 4 Mil Cub?


Recommended Posts

I want to keep my Banshee dune-able and I'm curious about the SLP Pipes. They are supposed to be torque monstors. I would not mind sacrificing some top end to have a bike that is easier to dune around and play on. I figure that the cub is going to make enough HP with any pipe but I'm worried about the lowend due to exhaust port sizes etc.

 

I have new CPI Big Bores on the way but I don't think I want to run them.

 

Thanks,

Justin

Whats wrong with them?I know there fitment just sucks and good luck changing spark plugs but do you not like the performance or is it the fitment?

 

Long Story :P First set did not fit, had to put dent in the pipe to clear the head AND use 1/2 inch spacer. Then on 2nd ride the chrome started to peel off.

 

Returned that pipe, new one leaks oil out of the seam and the other origional is leaking oil at the mounting tab.

 

Have another set on the way but I wish the first set would have worked 8 months ago. I just want to try somethign else and when I get the replacements I can sell them as new since they will be. 3rd times the charm right? but I think a Cub with alot of torque would be a killer setup for dunes.

its a cub its not going to have lots of low end it wont really come to life till 6500 rpms. mine you when it hits it will really scream.

Well my friends 7 mil cub has more lowened than my biek currentlyt does..

 

I would hopt switching to a 4 mil,and keeping my compression up would help wth my lack of lowend or at least help keep it where it is at even though I would be swithcing to a cub. Mind you I'm not riding trails but I don't want to have to keep my bike reved to the moon all the time. Thats alot of work on a 3 hour dune ride and make it more of a PITA than a fun ride. For example jumping off a small razorback I would have to nail that shit to keep the bike in power. I would liek to be able to slow down some and approach the razorback then Punch it and launch off it...Not have to suck in a my breath and Slam into it and bottom out my suspension / eat shit to keep the bike in power. Also I don't want to have to double and tripple shift down all the time if I hit some super soft sand. I want a fun bike to ride but want more power than where it is as now.

Any Dyno Runs to look at, preferably comparative ones?

 

Call Trinity or Nmotion if you want those. John Stallworth ran the Trinity's over the CPI's for the pikes peak hill climb on his 7mil cub. Not sure what type of curve he was looking for in that race but I'm sure he tested a few pipes.

Let me run them on my 421 and I'll tell you how they work. :biggrin:

 

A local builder runs LRD big bores on his 421 motor and it seems really snappy into the power a little more down low even with 39mm carbs. My rockets seem like they sort of come on the pipe around 4-6 but real weak and then they kick in HARD at 6K it somewhat helps for trail type riding. But I do know what you mean about jumping and wanting the power but its not there because your around 1-2K to low in the RPM's where a ported stock cylinder motor would still rip.
