I know xrsonly has the mikuni pupmer available for the XRL but don't hear of anyone using it... on my bikes in the past it was a given that a flatslide was a hands down advantage; is this not the case on the L?

Is the DJ or Dave's mods enough?

Would it be more beneficial if you were changing pistons, cams, etc?

Daves mods and a cv carb do very well.

I run a FCR41 pumper. The throttle response is the positive. Power output the same. As you progress in your engine mods, a flatslide might just compliment those mods.

Flat slide will not be as friendly if you will as the cv.

Very true. Mine has an occasional cut out at the WOT to 3/4 transition. Cant jet it out.

Big fan of the flatside. Easy to set up, easy to maintain. No bog or cutting out on mine. It's a must for the Batt relo/pod users.

Yeah, the CV carb doesnt do well with pod filters.

With a pod filter on a CV, there was a 1/3 throttle hesitation...:confused:

I had a Mikuni flatslide on my first XRL and sold it to get the Eddie. I'm on my second 650L now and did Daves mods to the CV and am pretty happy. But that could change in the next 5 minutes.

That is probably a keihin, they have a problem with the choke butterfly breaking off and getting sucked into the engine. I have a mikuni on my xrl I'm very happy with.
After much agonizing last week I put a deposit down on an 08 Husky TE610. :confused:

I'm happy with my flat slide no cut out or any problems easy to set up. Stock carb with Daves mods was good but I like the mikuni better and the price wasn't too bad.

Humm, I just got a mikuni pumper and honestly I'm about ready to chuck it in the trash and pop the stocker back on. It's got a wicked flat spot and sputter that I can't seem to jet out of it. Oh and tech assistance over at (name withdrawn) shop where I bought it has been no help at all. I'd say stick with the stocker.

These were the reports I had read when I finally decided on the FCR.

Try a post in the jetting forum, Eddie S. is very well versed in this subject.

Unfortunately I've gone that route. I've been jetting and re-jetting daily for oh about two weeks now...fun. :thumbsup: Sad part is my local shop wants $400 just to look at it...minimum! (Not gonna happen). :thumbsup:
