Regardless....all I know is that I was broken down in MX due to a problem that I payed a shop to address, and they didn't. I replaced the dried out orings McGuyver style, and was able to complete the next 900 miles of my journey and made it to my destination.

And yes...I will be interested in one of your rebuild kits and "fuel enrichment" plungers to take with me upon my return in July. I will be sending you an email soon. Thank you for your condescending "tone"

The needle seat o-ring and the cold start enrichment feed pipe o-ring sort of hold the float cage in place when the bowl is off. When the bowl is installed, there are three plastic tabs attached to the cage that hold it more securely in place by being sandwiched between the main carburetor body and float bowl.

Although condescending at times, Derek is only attempting to be accurate, very accurate. Once you understand that, he makes complete sense.

Here are two of the three plastic tabs Derek is talking about.

I've never heard of self torquing nuts. What a brilliant labor saving idea.

Maybe I missed this before 'tween all the carb posts but I finally understand the difference. Thx for the brief description.

Well, put my klr in the flea market and hoping to make the switch to a dr. Can't afford to spend a lot right now, so I'll be buying used and hopefully modded to my liking.

What about should I expect if all goes well, compared to the klr? I currently also own a plated XRR, I imagine a dr will be somewhere in the middle. I'm actually thinking about selling the xr next, assuming the dr is good enough off road. I think it will be.

I can see that in stock form the dr isn't really a 'highway' bike, but it seems like with a windshield it'll compare to my 2005 klr, or at least be close enough. I have a taller windshield and heated grips on it, got me spoiled a bit. I'm planning a mostly paved and light off-road 3,000 mile trip this summer, need to consider such things. The guy I'm going with is on a klr and rides it like a motocross bike. It gets interesting following him sometimes.

From all I've seen there is basically no issue with getting the bike hot, I guess for one reason or another it just plain works. Actually I haven't seen any issues that seem to really plauge the dr's, except for the third gear that seems to be fairly rare.

I pack light normally, so I don't see luggage being much of a concern. Some wolfman bags and a small luggage rack should do me. The bag I use on my luggage rack is about 20" long, I'm pretty sure it can fit longways. It basically fits everything I need, I'll just lose the back seat cooler storage.

Hopefully this can work. I tried to get a dr last fall, ended up with a trade deal for the klr and somewhat regret doing it. If anyone's looking to trade I'm listening.

intimantors install help

Hi,

I'm installing ricor intiminator and have some questions:

The current oil level, without any spring (or anything) fully compressed, is about 180mm from top of for to start of fork oil or about 7 inches.

Do I fill to this level after intiminator is back in and fill to 6.5 inches (fully compressed), as per the instruction on this thread: http://www.advrider.com/forums/showthread.php?t=468588

Preload:

If the base thickness of the intiminator is around 15mm or so; can I just remove this amount from my spacers to give my my original preload??

thanks heaps

I'd go to 160mm from the top and if you're using the original springs, leave the spacers at stock length.

Original preload is usually not enough preload...

From what I have heard a "self torquing nut was not possible last time I heard...that is if u want any kind of accuracy.....

The only thing I found was there was a lot more room on my 03 KLR for comfort when on long adventures and less need for bigger tank...Just fixt the doohucky and every thing was fine then I got the idea I needed something different. What year is ur KLR?

The stock spacers were to much preload with the Intiminators when I first installed them. Ride was very ruff. Called Ricor and talked to a tech. After taking his advise to make a shorter preload spacer I am extremely happy with the performance of the front forks. Sorry but don't exactly remember the oil level that I set but belive it was 6 inches.
