@timberfoot

I thought the same thing when I bought my KLR, however, mine is 24 years older and has been...not well cared for.
@Damocles, @DPelletier, and @pdwestman can all tell you about how much of a basket-case mine has been.

The performance is tractor-like (which I'm looking into what I can do to bump up for the least amount of money), but very proven and reliable.

I hope you enjoy your bike and welcome to the forum!

DO NOT QUESTION IT!

Hello all

I have contacted a local Harley shop in Adelaide. I spoke to the very friendly and helpful guy in the spare parts department. He told me that he has sold a lot of CV40 carby slides for KLRs and several other bike types too.

I have arranged to pick up a new slide on my way home from work tomorrow. I don't know if I'll have time to install it this weekend though. I have a very busy weekend this weekend. It is daylight savings time now though, so I may be able to find the time.

I will let you all know how it goes once it's installed.

Thank you all for your advice and well wishes

Cheers
Timberfoot

Hello All
I installed the H.D. Carby slide today.

I can tell anyone that wants to know that the Harley slide is the same part, as the Kawasaki one. The only difference being the Harley slide does not have holes in the side, whereas the Kawasaki one does.

There is a definate, but moderate improvement in acceleration at 3500 - 4500 rpm. I took the bike out and attained 140kph before I had to slow down for a turn. I don't think the bike had a lot more in it. I did not drill out the hole in the slide. I would have had a greater improvement in acceleration if did, reportedly. To reiterate, and sum up, there is a definate, but moderate, perhaps moderate to fair improvement in performance. I think it was worth the $74 i spent on the part.

May be factory lean now like mine was. Shimming the needle made a huge improvement.

Yep; next step (if you want to go there) is to install the KLX jet kit and pull the airbox snorkle.

I'm not sure how I feel about he KLX kit. I may do it, but not just yet. The bike does perform better with the slide change. I would recommend it to Australian KLR owner. It is fairly easy to do, and there is a marked improvement in performance. it's still not a racing bike, but it goes noticeably better when the throttle is twisted a little bit aggressively.

I used the Clymer 2017 KLR650 manual to guide me through the job. Interestingly, the instructions in the manual included removing a vacuum hose that does not exist on the 2017 model and did not mention the little coolant/antifreeze line that plugs into the front of the carby

The KLX kit is up to you; if you want a bit of a boost and better throttle response, do it...if you're fine all stock then that's good too. I do the KLX kits on mine to correct the factory EPA compromised jetting; the KLX needle/jet was designed for the same engine without the EPA considerations and simply works better. I didn't do it for power.

The coolant line to the carb is an Australian (maybe european as well) thing, we don't have that in North America which is why the Clymer doesn't mention it.

Cheers,
Dave

Hello Dave
I didn't realize the KLX needle is designed for the same engine. The main reason I did not want to install the needle was that I didn't want to use a part that was not designed for my bike. I now think that I will put a KLX kit in my carby...

Kind Regards

Matthew

Matthew,

Full disclosure; the KLX needle is designed for the KLX which although similar and shares displacement and some internal parts, is not identical. it has a different head for more flow, different case and a gear driven balancer. .....but the KLX jetting works perfectly on the KLR.
