So far, awesome machine! Changing out the 14t sprocket for a 13T makes a huge difference! Stock exhaust dropped 10 lbs off the bike and removing the rear fender/ lic plate assembly for a DRC Edge2 install dropped another 5 lbs and cleaned up the tail end quite nicely. Stock tires are find for light trail riding, but slippery hard pack or muddy conditions really show how a tire that does well on the street, makes for a lackluster woods tire. I have had this bike on technical terrain and the stock suspension has faired well. I am 190 lbs and the rear shock did require some addition of pre-load. Suspension upgrades are on the 'to do' list on down the trail.-

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.

I wanted to know if you guys have any tricks to fixing this. I have read a lot of forums but I have heard about the ice cracking the pipe. Is that true? Has any had that experience? I will put pictures up when I get home at 3

Anyone ever stick a thermometer on the header pipe after a ride to see the temps generated? Or the whole system for that matter?

Did a search, but didn't find much. Wondering if anyone has the FMF Powerbomb header and results. Their claims sound impressive- but I know how that tends to go. With all the mods I have to my engine, I figure that I stand the best chance of seeing a worthwhile difference. Heard good things about the oversize Powroll header, but the FMF looks like a better mod than the Powroll, and Powroll's website is AWOL lately.

My 2003 450 was sold to me with a fancy racing exhaust -- an FMF Titanium 4 with an FMF titanium Power Bomb header. While these 2 components are no doubt lighter and better performing than the factory original stuff, they are loud and cause the bike to pop on deceleration. I've even purchased and added a "quiet core" insert and USFS approved spark arrestor end cap (both titanium as well, I believe) but the bike is still too loud for my tastes. The Yamaha dealer tells me that these pipes are all prone to the problems I've cited for bikes used at altitude and suggests I go back to the factory stuff. The guy who sold the bike to me actually gave me the original muffler (virtually unused as the original selling dealer put the FMF on it before it left the showroom). But he could not find the original head pipe. I've been running a WTB ad here on the classified page asking to purchase a factory head pipe, but have not gotten even one offer to sell. I've found them on eBay but it seems they are usually in bad shape. That leads me to a question for all of you: Are there aftermarket head pipes (preferably stainless for durability) that will work with my factory muffler? If there are, whose pipes represent the best value? I'd also like to get your take on any other possible solutions to my noise and decel popping from the FMF. It could be there is a better solution to going back to stock. TIA

Need help with my header bolts that connect to header plate, or whatever it’s called, on 2017-2020 Honda Crf250l any ways, it seems when I took my header off, the bolts seemed to be bent out About 1/6” each outwardly.( so now plate won’t go over them) just enough where I cannot Re-install my header. I was thinking about widening the holes on header plate that slides around pipe header, With a drill or rat tail file on the backing plate that secures the header. I also don’t wanna strip the threads on the existing head bolts, so I heat and tap with double bolts ? Or is it really necessary to double bolt and then wrench out the head bolts and install new head bolts which I’m not sure what silicone or locktite or what ever , if even any sealant was used when factory screwed them in. possibly I’m riding to hard and my header bolts bent out a little due to so much heat?? is there a better way, maybe slight heat and a light tap? I just don’t want them to break off, because I DONT wanna play the game “get the snapped/broken head bolt it out” w welder and welder nut anyways I really don’t wanna snap the bolt so im depending on someone on here please and also why we are on the topic , what’s the correct lb torque for the mega bomb fmf header when I do get this alll figures out thanks and please help if you experienced this on a 2017-2020 Honda CRF 250l

El Cheapo Partial Header Wrap - An Edelbrock installed on a Honda XR650R rests painfully close to the stock header. One cheap method of isolating heat from the bowl is to pick up a muffler patch kit from your local auto parts store. These kits contain a piece of foil backed fiberglass insulation, screen and glue (the glue you don't need) and sell for under five dollars. A can of flat black header paint can be used to spray the foil and screen and stainless steel zip ties will look better than the tie wire I used. After cutting the insulation and screen to size, I wrapped some heavy duty aluminum foil around the header, followed by the fiberglass, then screen, then tie wired it all together. The wrap in the photos has been on the bike for 2 years and other than needing some spray paint touching up, is still working fine. The fiberglass insulation will soak up water, so after washing your bike, be sure to run it long enough to burn off any water collected. Special thanks to Dafna for taking and posting photo's.
