pipe coating

Recommended Posts

I have the raw metal version of the DEP pipe and so far ive been getting by with using wd40 and a scotch brite pad to clean it when some rust appears. Well last weekend i went riding in mud and it got really rusted. I managed to get all the rust off but there are black spots left on the pipe and i cant get them off with the scotchbrite pad.

You guys have any ideas on how to get those spots out?

Also afterwards i wanted to coat it with some kind of high temperature coating to stop it from rusting so easily. Anybody got any suggestions?

Thanks for the help :busted:

find some local ceramic coater and get it ceramic heat coated, or nickle plated, but if you dont want to spend some cash just use high heat engine paint. if you want it chromed you might as well get a new pipe. thats expensive.

Powder coat typically holds up decent...about like a kawisaki two stroke pipe...though I don't like the glossy look...

You may be able to find a local guy or buddy who has the oven and spray tools to do it themselves.

I couldnt imagine it being too expensive for a expansion chamber. my dads cobra pipes were like $200 and those things are pretty big. its probably more expensive than powder coating.

Sand paper will get the black spots out. You can just use high temp paint on the pipe if you want.

what grit sand paper? like 800? I did want to go the hi temp paint route but wasnt sure if they offered a high temp clear coat or something close to it.

Yeah, 800 would probably work. Then go over the whole pipe with a scotchbrite pad to make the spot you just sanded blend with the rest of the pipe. I believe they sel a high temp clear coat engine spray paint at auto stores.

I'm gonna bead blast my old pro circuit pipe. I may use hi temp black or the clear does sound appealing.

Do they make a clear enamel that's hi temp?

I have used the high temp clear before. It turned an odd color on the first 8-10 inches of the pipe, but still looked much better than the rust.

that sounds interesting. I might try the clear. If I don't like the discoloration for the first few inches I can always blast it again and paint it black :busted:

I dont think you would hate the way the clear discolored...the color was not clear, but it was not black. It was not blue....maybe a combination of all with some gold thrown in for good measure.

I like it because you can polish the pipe like crazy before the coating. Once you clear coat it, the bike basically takes care of the coloring. The first 4 inches of pipe leaving the cylinder went black. From there it started to lighten up. Most areas had sort of a goldish finish.

The best clear coat I found was only good up to 500 degrees. Let me know i fyou find soemthign better, please.

yea same here. I just drove all over town trying to find some and the best i could find is the 500C stuff. I wasnt sure whether that will be good enough so i ended up not buying it...

RCannon - is that the stuff you used?

Yea, thats the stuff. I felt like it was not enough for the first four inches of pipe, but ok after that. Even still, nothing bad happened..it just turned black. No fires, bubbling or anything fun.

thanks for describing that, roland. I'll do a little shopping and see what I come up with. Now that my motor spins well, I'm onto the cosmetic stuff :busted:

ok thats good, and it still works like a clearcoat by protecting the pipe from rusting right?

      Ok so I'm looking for opinions from those who have been on yz125s and 150 exc/xcw's and maybe the ktm 200's exc/xcw's. You gotta be out there.
      Here's the deal...I'm 5'7" 165lbs. A couple years back I was looking for a small bike for my wife to learn on and for me to play around with and race. Could only afford one bike. I got a '09 ktm 105 sx. Once I got it sprung for my weight it was great. I have been top five consistently in my local harescrambles B class, believe it or not. Ya, you were not the only ones shocked. And did pretty good in the local mx races as well, junior class up here in Canada. Lack of power was sometimes an issue but I learned to deal with it and just scream, scream, scream!
      However my wife is a complete beginner and she is scared of it. I have since moved her to a 4 stroke.
      Just got a mint '01 yz15 mid summer. Like less than 200 hrs! I have absolutely loved it on the mx track. Suspension is perfect and I love the extra power. I had planned to set it up for woods/mx with a suspension revalve. However, did a harescramble race a month ago that was really technical. Granted I have not done anything to the suspension minus clickers, had too much psi in the tires (13 front and 15 rear) (yes I know that's wonkey, I only had time to get a heavy duty tube in the front and had a stock tube in back. Less psi in the back would have been instant pinch flat because its so rocky) and it was running rich. I had to scream the thing to keep it running and even changed a plug mid race. Well I'm sure you can guess but it was the worst experience I have ever had on a motorcycle. The more open sections I passed a lot of people but the tech sections required way more effort than I liked and the suspension beat the hell out of me!!! Like my knees, wrists, and shoulders were just done. (I was out there for three hours).
      So keep in mind that I just came off a 105sx with suspension mods (set up for woods/mx). I have no problem slipping clutch and shifting precisely, yatta yatta. (I don't think the 105 would have done well here either due to even less power, however...) I've been second guessing fixing this 125 up for woods ever since I rode a friends '09 ktm 250xcw. I rode it on a local mx track. The power was just so effortless and I was absolutely floored by how the suspension worked. I never thought that I could hit the woops that hard and clear every jump on the track on an xcw and feel THAT good! It felt a lot heavier though, and I think the price tag on these things are going to be a stretch.
      So here's my question. I want the lightness of a 125, but want to be able to race both woods and mx. How does a 150 exc/xcw ENGINE compare to an mx 125 engine? I love the 125 engine, but more low end would be usefull in tech areas. But if there is not a huge difference, I will probably just revalve the yz for woods and go tubless, etc. The 150exc's are so expensive and I hardly ever even see one for sale unless its brand new. I don't want the weight of a 200/250/300. I barely touch the ground on a 125....so it has to at least be light. Is it worth waiting for a 150 engine? Thanks guys.

      Hey TT, I know there's endless topics on YZ250/ two stroke tuning in general but I have not been able to find one that helps me get my 09 YZ250 set up for my riding style and where I ride so I'm here asking for help. I got this bike around 1.5 years ago and have not known how to set it up properly. I know no one can give me a perfect set up but I'd like a good starting setup to work from and tweak to perfection. Throughout this time I've had this bike, its always been covering the bottom of the entire silencer and dripping all over the swing arm and rims with oil. Also, the joint between silencer and expansion pipe has oil around it too but I've heard I have to close the gap a little to squeeze the silencer a little tighter and stop the leakage there. I don't have too much experience messing with carbs but I've messed around with previous two strokes and tuned them a little better. I change the oil on my bike after 15-20 hours on it and clean and oil the air filter after almost every ride. The sparkplugs never last me more than a few months but recently have been lasting me no more than a few weeks. With the excess oil from the pipe and spark plug fouling you can see why I need to set my bike up to stop this. 
      The bike:
      Completely stock with V-Force 3 Reeds and a FMF Shorty silencer. 
      Usually running around 32:1 premix with 91 pump fuel because I prefer to keep it well lubricated instead of running rich.
      Riding:
      I ride enduro in Ontario, Canada. So mostly single track and some fire roads but nothing close to MX and not a lot of time wide open. Therefore, probably mostly 1/4-1/2 or 1/4-3/4 throttle range.
      Where I ride:
      Usually 0-500' above sea level. With temperatures ranging from around 15-35 degrees Celsius (55-95 Fahrenheit).
       
      If anyone can give me a setup to go from, that would be very much appreciated. Even multiple set ups for different temperature ranges or any suggestions would be much appreciated. Thanks and sorry for the long read, I just didn't want to leave anything out. Ask any questions if you have any, too.

      Hey guys... so I have a problem... I took the bike at Cal City, broke it in, and while I was doing so, the bike was bogging in first gear (Yes, first gear). Also it doesn't idle at all. I have to keep blipping it otherwise it'll stall. So I adjusted the screw circled in image 1. Well I was listening to the sound of the of the bike, yet the rpm's weren't increasing, and it was still stalling. So then, I unscrewed the screw in image 2, well I found out that it was fully twisted to the right. So then, I twisted it to the left, still nothing; it was still stalling... where's the idle screw? I am sure that the screw in image 1 is for the air/fuel mixture screw, and the screw in image 2 is the idle screw, just broken? I don't know, any and every help would be appreciated.
