Hey guys have a question on the FMF Powerbomb header

I'm replacing my existing header (unknown brand) and noticed that on the powerbomb, the left tube is a decent bit longer than right tube. My old header doesn't have this, and is pretty equal length.

What are your thoughts on this? I know equal length headers work better. I also noticed the part where the two tubes join is kind of pressed together into a slightly smaller opening and then enlarges

I know it might be only 1% difference, but since I'm spending 300 dollars to _upgrade_, I want to make sure I'm getting something that's an upgrade, otherwise I might as well keep the current header (maybe needs a recoat, but tube might be a good setup)

Thoughts and experiences / comparisons welcome! Thanks!!

If your header is stock, just take it off and take a Dremel to the squarish welds at the manifold.

Acerbis, IMS, or Clarke Tank?

Hi Inmates,
I'm considering upgrading the stock tank to one that will carry a bit more fuel while out in the boonies
Are there any preferences as to manufacturer,Acerbis, IMS, or Clarke and if so why, size, shape etc.
I don't need something with enough capacity to cross deserts. just a gallon or two more, plus something that won't be in the way should the bike take a tumble.
Thanks
Mark.

I am about to embark on the mighty 300+ page read to see whats been happening with these great bikes.
Cheers all and I look forward to learning a lot in the coming months

I have the IMS 4 gal..at first I was a little disturbed at the front end weight when the tank was full, but now I am use to it..abt 160 miles to a tankful (ballpark, YMMV) and it seems to be a pretty popular tank.

I have the Baja kit on mine and have so for going on 4 years now..no issues at all. Have replaced the headlight bulb a couple of times and swapped out the OLD bulb (1157 style) tail light with the LED one and have not relaced any of the turn signal bulbs, no need to, they still work!

Over all, on the Baja kit. It works and was pretty easy to install and it got my bike tagged..I can now ride my dirt bike into town and thumb my nose at the cops!

Stock 2.4 gallons
Clarke is 3.8 gallons
Ims is 4 gallons
Acerbis is 5.8 gallons

Clarke tank because of shape clears most all front end changes... Other than stock top triple, Usd fork conversion, etc
Ims tank is longer and sits a hair lower but hits w/ most if not all top triples other than stock, and some front blinker locations.
Acerbis tank is really an ADV tank. I have not tried one with other than oem front goodies...? Tho it is crazy big, if filled only to desired 3-4 gallons, weight sits much lower than other two tanks. This is not to be over looked cause adding a oversize tank is gonna change handling on your xr... Besides the obvious added weight to front end Clarke and Ims sit higher than stock which makes them feel even heavier than the added 8lbs

I can confirm that the Clarke tank does not interfere with a USD conversion. Plenty of clearance actually.

I've had the IMS 4.0 installed for 6 yrs, no probs. Recently, anticipating some rides where the range could potentially exceed 150 miles between gas stops, instead of spending $$ on an even larger tank I bolted a Kolpin 1.5 aux tank to the Cyclerack giving me an additional 60 or so miles. I can conveniently remove it at anytime and install it on different bikes as well.

Same tank installed on the KDX..

Exhaust Manifold

Hi all, just doing some maintenance to my 98 XR. Took the exhaust headers off to give them a good clean and replace the gaskets. Removing the headers revealed that the previous owner has perhaps had some trouble with the studs in the past. Only two studs remain of the four. The other two have been replaced by bolts, one of which it looks like has stripped the thread inside the head. I plan on using helicoil to repair the thread but before I do I am just seeing if anyone has any horror stories with this kind of work/method before I set about doing it.

On another note, does anyone know if you can still buy acerbis upper fork guards? If so a link would be greatly appreaciated.

Many thanks.

What can you guys tell me about the kicker ratchet!? When I pulled the side case off (to replace cam chain) the kicker ratchet fell out. I know how it's supposed to go together but the manual is a little vague on how much tension to put on the return spring. Anybody have pics orrr....

Thanks in advance!
I'll shoot some pics later this week when I pull it apart.

I'd be interested in hearing too. Actually, I'd also like to hear if anyone has a source, or if anyone wants to get rid of some of the Acerbis/SRC upper fork guard sliders. I managed to score an SRC fork brace, cheap. Has the holes for the slider mounts......since I'm doing this as an old school privateer rally/ADV bike I'd like to add those upper guards too.
