So far so good. Checked/repacked/replaced all worn bearings, fluids, tires, clutch plates, brake pads, chain, sprockets, bars, grips and levers. Replaced all incorrect size/length bolds, nuts, screws. Removed a ton of red loctite. Usually at the expense of the threads and or bolt, nut and screw! BAD TOAD!!! I want to convert to electric start. The parts are out there. Let me know if you have done it or know someone who has. -

TRX400EX WHITE BROTHERS E-SERIES MUFFLER MOD TO FIT 93 XR250
CRF450XINOZ posted a topic in XR250R & XR400R
With the White Brothers E-Series mufflers no longer being made & unable to find a secondhand one to fit an XR250 I had no choice but to modify one to fit, After looking at the mounting brackets I new the TRX400 muffler could be made to fit This is basically the same although mine must be a later revision as it has 4 bolts on the end rather than 6 rivets so it can be re-packed easily First step was to drill out all the rivets at the front & disassemble it then trim the front section of the muffler off to clear the frame, 2-1/4" was cut off the front section, 2" would be enough (The shorter the muffler the noisier it will be) After cutting the body of the muffler, Drilling 6 new holes (which need to be precisely in the correct spot to line up with the inlet piece) it was ready to repack, I bought some 2" stainless baffle tubing & removed the 1-3/4" baffle tubing that was inside the muffler, Got some muffler packing/matting type stuff & some stainless scourers from the local supermarket Cut the baffle tubing to the correct length, Slid the necessary amount of stainless scourers over the baffle tubing then a layer of the muffler packing sheet wrapped around that & it made a pretty snug fit when it was slid back into the muffler body I have found the stainless scourers work quite well at soaking up the sound rather than the matting wrapped around the baffle tube which does not allow the exhaust noise to be soaked up in the muffler body I bolted the front section back on rather than using rivets so it can be disassembled again easily if needed My newly fitted XR's Only stainless header ends in 1-3/4" so I bought a 1-3/4" stainless mandrel 180/U-bend to make the intermediate pipe between the header & muffler, Some tricky cutting & working out is needed to make it all line up neatly & once it is TIG welded it will look rather nice, I hope to have the intermediate pipe welded up in the next few days if I get a chance to get my bike to the exhaust shop where I used to work or an engineer shop down the road, Both can do excellent TIG welding just need to see which one of them will be able to do it first? The White Bros muffler should work well with the new header pipe, I did not get a chance to ride it with the new header pipe so with the new header & muffler it should be nice -
Can somebody tell me what's up with my exhaust??

Anyone a skeptic??? I sure was, until last night. Here's what I did, and to what: I dented my FMF Ti header pre-running for the Baja 500 recently. Sure it wasn't too bad, but bad enough where people see it and say "hey... your pipes dented..." Enough to make you want to fix it right?! After reading on several forums about filling the pipe with water and putting it in the freezer to pop out the dent, I was pretty skeptical. I thought, "how can freezing water be that powerful?" Also, not being any kind of engineer or scientist, I had to try it! Skeptic? Yes. That is until I actually did it last night and found it to be 100% true! Simply amazing and so easy! Here's just how easy it was: - Took the header off in about 5 minutes (from CRF450X). - Added enough water to fill the dented area of the pipe, plus a bit more (did not end cap the pipe or plug anything). - Placed in freezer so that the pipe wouldn't leak any water. - Woke this a.m. to a near perfect repair! This repair sure saves taking the pipe to a welder (which I am by hobby) and having them use a rosebud and air to blow out the dent!! Plus, this is MUCH cheaper. You may need to attempt this two, three or four times to get the dent completely removed. But don't give up, the reward is worth it. Good luck!! And have fun! An edition to this article by sootgrinder In the tech tips section there is a nice write up on how to use the freezer to pop out dents in your exhaust header pipe. It is a nice article, and the process works well for four stroke pipes that are a consistent diameter, I.E. not stepped headers or Powerbomb type headers. But it would be nice is you could put some language at the end of the article to warn against using this tip on stepped headers and definately not two stroke expansion chambers. I have personally seen expansion chambers ripped apart at the welds when trying to use the freeze technique. I just want to prevent someone from ruining an exhaust system, and getting upset because they thought it would work for expansion chamber pipes as well.

Anyone on here ever went from a MRD/SSW (Z-PRO) on a DRZ to a FMF Q4 with the powerbomb header? if so please give me your honest review and thought on this, thanks.

Cons - Not the fastest 450 ever made OEM Rear Shock Sucks. Once hot, no rebound damping Air fork not everyones flavor Pros - Light & Nimble Reliable Good handling (After some suspension mods) Map Switching Strong re-sale values -

Third bike and second supermoto. So far it is my favorite bike. Thing is fun to ride on the streets and can touch dirt without exploding. Only problem is it's going to take up a lot of my money making it even better. -

Bought an old race quad and redid it. Ended up buying new plastics, so there are pics with it yellow, some red, and all red.
