As well as s***y roads (200 yards from a farm) the roads have had their first salting of the winter which plays havoc with my polished aluminium wheel rims.

Salt plays havoc with everything except stainless. No need corroding your bike....of course, sliding off the road plays havoc with things too.... Wink

I like spending other people's money too. Can you help with that? Roll Eyes

At the moment, I can't spend money on unnecessary things...as much as I'd love to, anyway. I need to get across the country first.

That is a good idea though...if I could find a good used one that doesn't have the cam journals all worn out. That and the FCR41 are still on my "to-do" list.

Does the Savage have any other nasties. Clive W

I am not familiar with the carb you guys are talking about, but I have replaced the stock carb on my bike with an Edelbrock flatslide, and it runs great. Took a little while to get to the right jet needle and then get it adjusted properly, but once doneit is very smooth. I had significantly modified the stock carb with larger pilot and main jets, modified needle and throttle slide for quicker response, and also added a Dial-a-jet to bring up the rear. Made a big difference in performance but not as much as the Edelbrock.
Have a good New Year.

I have read lots of good things about the edelbrock on the XR 650 R site. The FCR41 is actually 42mm at the slide, what is the edelbrock? Clive W

The Edelbrock I am running is a 38mm. This carb is used on both the 883 and 1200 Sportsters, stock and modified, and on stock big twins...so it is more than capable of taking care of the Savage. The needles available for the carb range from #3 -#19 I believe, and the one that works for the Savage is a #6...lots of room to grow fuel-wise.

Can You or do you know anyone who can fabricate an exhaust pipe if so you need a 1 5/8 od pipe which at 1/16 wall thickness will give a 1.5 inch (38mm) i.d., the optimum for your carb.
As far as length goes 47inch tunes things in for 5000rpms and 52.2 works around 4500, 58.75 is for 4000rpms and peak torque,3700 = 63.5 inch's.
These numbers are for open pipes.
I you want silencing you must use a absorption type silencer (perforated tube) which has an i.d. at least 10% more diameter than the header.
Hope these numbers help.

I am planning to build a header pipe and reverse cone megaphone for my Savage to test the power characteristics. I will probably use 3 header sizes (1 /38", 1 1/2", & 1 5/8" ID), with variable lengths from 30" to about 38", and probably 2 different sizes of the megaphone...not sure of the exact sizes yet. At this time I am MARGINALLY proficient in welding, and need to buy a MIG welder before starting the project. So, to answer you question, no I am not able to make one right now, and I do not know of anyone who makes custom pipes. However, if you call around to muffler shops in your location, you will probably find someone who is willing to do it for you...or at least get a name/number of someone else who does.
Good luck, and let us all know how you make out.

Go to www.headersbyed.com, you will find the HOLY GRAIL of exhaust/header/muffler info. ED, has been building headers for about 40 years and knows more than you will ever see/read in any magazine or book. He explains what works and what does not....and why. Check it out, you will be amazed.

I have been designing (and re-designing) motorcycle exhausts for 20 years, specializing in 1,2 and 4 cyl both two and four stroke, mainly for sidecar racing use, but have no experience of big V8's or 12's etc.,which appears to be what Ed's site is about.

My KLX pipe was made by sand packing, heating and bending to give the exact shape required, not just welding a series of bends and straights together.

In my experience gas and tig are best for welding exhausts/headers.

Are Your header diameters inside diameters?
