Pipe Building

Thankyou very much. When doing the cones is it easier to make a straight pipe and then bend it or use a cones that are cut the right angles?

Also Steve how does the power of your pipe compare to the FMF Gnarly on a EC250 power wise, and how much does it cost?

Thanks for all the help.

Thanks

A longer head pipe gives more low-rpm torque and a flatter hp curve. A shorter head pipe will give you a steeper hp curve and will rev quicker. If you want to do some testing first start by replacing the left side powervalve cover with a flat plate. That's a small dose of the same thing.

Start with a bunch of 1-2 inch straight cut cones and then trim them or overlap them to make the curves.

Our pipe was really meant for mx, it just hit and pulled harder all the way up the hp curve. I was surprised that so many enduro type riders liked it.

Cost...? We don't have anymore of them.

Steve, so, if you had a section of the headpipe cut out, (Messico Pipe) and installed an LTR P/V Cover would there be any thing to gain from this mod? Since the P/V Cover helps w/ lowend, and the shorter headpipe increases mid would the 2 mods work togther?

Thanks

More likely they would just cancel each other out. The powervalve cover is part of the header pipe.

Steve,

Thanks for the info

I put a Motowest pipe on my '98 EC250 and it did hit quite a bit harder than the stock Messico. After waffling the stock FMF pipe on my '01 XC300 I put the Motowest pipe on that bike and could never really tell the difference between the two.

What I really liked about the Motowest pipe was that it was made from heavier gauge steel and tough. In six years of crash-testing that pipe only has one ding and has never been bent out of shape. Can't say the same for the three FMF pipes hanging in my garage.

Thansk for all the help.

I had bothe the motowest, well one of the prototypes apparently, and the FMF,, the motowest was better,, had more low down and even tho it had a real hit,, it came on smoother than the FMF.. The FMF felt like a true MX pipe,, less bottom,, hard hit and signed off early.. I still have my MW pipe,, but its almost crushed beyond use.. I'm thinking my winter project it to bring it back from the dead.. and mount it back up to my 97 ec 250.. going 2-stroke DS bike with that one..
