Pipe Design !!Pictures!! on page 4! Nasty fast.

Very good job, I can't wait to see a finished product with proper welds.



Oh yeah, swap your tires around! lol Those pro-wedge's are meant to be run with the scoops backwards.

[RubberSalt]

I need to, now that i have more hp. Some reading I did claimed i could run them backwards, for lower hp machines. I need to test them the other way. Maybe when i start tuning I'll swap them. I was happy to get them pro wedge - $30 :-D

[RubberSalt]

Well, it's been to long for me, atleast 3 days! Thursday looks to be my next chance to tune it in. I can't wait to see what the bike does then! It makes me sad, i got this beautiful hideous pipe that i haven't got to really play with yet lol.

I'm strongly considering using my 34mm carb, i do have big reeds now.

My pipe works. Hit 3rd gear where i normally top out 2nd. Then i lost it and hit the ground pretty damn hard with my knee.

I don't normally drink, but right now, i am. Pain is gone. I also have ice on my knee and my leg is being kept elevated and straight.

[zzmegad]

take care of those knees, ice is good, knee pads better, my knee just started bothering me again last month from an injury that happened over 10 years ago... And it's been fine this whole time, wth

When it got on the pipe after tweaking the jetting some.. DAMMN it pulled like a bat out of hell on steroids!.

I've started taking vitamins, to help target what my body needs.
Vitamin A
Vitamin C + rosehips
Magnesium
Calcium - liquid gels
1 more i cant remember right now.

[Chazz of Blades]

I made a booboo about a year and a half ago, I layed a mini bike over in wet grass, going MAYBE 5-10 mph, cracked my right kneecap in between ground and metal tank. I can't ride in the backseat of a car anymore, and my knee still hurts like hell every now and then.

[RubberSalt]

I'm going to have to figure a home nasty fix remedy for it. Cut it open, JB weld the bone together, use my acetone jbweld mix.. lol. I've got 2 knees to practice on.. right? lol

I want to make a 2nd pipe, but a swing arm is more important.

[RubberSalt]

I've noticed a fn thing about my pipe. It pulls harder when cold. Sounds like i need a wider stinger or to extend the pipe a few mm.

[RubberSalt]

Looks like I'm going to be starting on another pipe soon. This 1 is for a Blaster. I'll keep this thread updated once I get started working on it. I know it's not for a 3 wheeler, but it's still building a pipe!

[Six Stroke]

Oh yeah, If any of you want some pipes designed by this neat little program of mine, let me know.

I'll need to know a few things though. Width of exhaust port. More or less, as close as you can get to the total surface area. Stroke, bore, exhaust port durations and the transfer duration. Desired RPM range and what type of pipe you'd want. High HP with narrow power band or Low HP with wide power band. I prefer a wide top end power band :-p


And what bike/engine it's for

I may have to take you up on that when my YZ Moto project is a little further along. Something better than a stocker 175 pipe would be righteous.

[RubberSalt]

Now that my knee is useable - im thinking about a new pipe... Out of frame design.
The 3 issues i came across with the YT - cramped in the frame, tuned length made the extra shorty exhaust meet the end of the grab bar, many bends, pipe is right above the engine - less cooling on engine

Out of frame = no cramped areas, no length issues... and less bends... and more air flow to engine & extended cooling fins = more comp i can have
Out of frame downfalls - if i roll bad, good bye pipe, pipe temps will be hard to maintain, have to design it far enough away, that its not in my way.



btw - i got a mig welder to use now lol
