e-series?(does length really matter) RodH or Mr Porrit

5 posts in this topic

I was just looking on Rod's site and noticed a picture of his e-series Hawkins replica and noticed that his muffler extends way past the side cover compared to mine as I can only just see the start of the E-series emblem due to the side cover, as far as I know I have an e-series s-bend, how many types are there? and what does the differance in length do? and finally what header would you run with it?

P.S. RodH if you havn't yz-timed your bike yet, do it your missin out on a heap of fun, I didn't think that it would be advantagious in the bush, I was wrong..

Size always matters!! your Mrs should tell you that!! :D:)

There is 3 E-series S-Bends to my knowledge though I think only 2 are readily avail.

The STD, Hawkins (longer) and the Shorty.

Bottom-mid orientated pie, and a mid pipe.

longer headers give more torque/lower the peak torque. but it sounds like it was just shoved in the tailpipe a bit further!

Hey Matt, it's good to hear that you're making a speedy recovery, but would you be able to answer me this: I think that I have the shorty muffler on my bike, so could I run a tapered header or a longer one to try and increase the top-end? or would it just be detrimental to the performance? The reason I ask is because I rode Mitch's bike last week-end and although he has the super-trick airbox, this bike just goes absolutely balistic from midrange to topend, where as mine seems to make most of it's power from bottom to the midrange.

If you have the S-Bend then you really have the wrong pipe for a screamer from mid to top.

Don't get me wrong, the S-bends are an awsome pipe, but if you're going for a mid-top bike like I did the the Pro-Mega is the pipe you want with a short hi-flow header.

Also disc numbers play a big part.. my YZ4F feels strangled with any less than 10. There is a big difference between 8 and 10.. not much (if any) down low but the mid-top is VERY different.
