KLR Thumper Well my bike has 15000 km so I'm sure the ring is as seated as its gonna get. Well I'm gonna take a ltr of oil with me this weekend but I'll let yas know it I use oil or not. 500 km a day of hiway at 120-130 km Ann hour will show it

LoneRider Maybe this is one for "Mythbusters."

Wonder if anyone would perform a "blind" test; i.e., have a dozen or so trials, mixed PCV valve mod and stock configuration, without the rider's knowledge of whether a PCV valve or a plain tube connected to the air box.

Then, after each trial, ask the rider whether the PCV valve mod or the vent tube only was in place, sight unseen . . .

I appreciate your honesty and integrity in reporting your experience. Possibly, your rings seated more fully, independent of the PCV valve mod, reducing oil consumption. On the other hand, if the PCV valve mod is effective, seems like it's "with" and "without" effect could be measured, perhaps even explained.

KLR Thumper I have no idea. I also did a ton of other mods at the same time. Like the Doo and .22 cent but they should no effect on oil consumption. I'm not entirely sure if the PVC mod did it either. But this weekend will be the true test on. I had a good gain in performance but like I said, lots of mods were done. I sort of wish I did one mod at a time to see the benefits individually.

Congratulations!

Any idea HOW a PCV valve in your crankcase vent line prevents excessive oil consumption?

Some have suggested a "crankcase vacuum" somehow is responsible, but no crankcase vacuum has been detected, in normal operation, with or without the PCV valve mod, ball-and-spring or reed valve device.

Did you notice other benefits (e.g., increased power, enhanced engine compression braking, better fuel mileage, improved ring seating, etc.) also, as others have reported?

Regardless, glad the PCV valve works for you; still curious about the operating mechanism.

Seems the way with the PCV mod. All of the things it is reputed to do actually happen, but hey are vanishingly small in effect. No one has been able to record the effects!

Well I'm not entirely sure but I have put 1000 km on my bike with the PVC mod and I have not had to add a drop of oil. Normally by now I would of used a half a liter. Not saying its the pVC mod yet but for some reason I'm not burning oil. I drive it the same way I always have "hard" but this weekend I will put 1500 more km on in the mountains and see what happens. What ever happened I'm happy with it!

My goodness, what more do you EXPECT from another washer? Why not TWO more washers? I know, FOUR more washers!

All a waher does is, fuel-enrichen the mixture at slide elevations in mid-range operation. If your bike's running smoothly and responsively between, say, 1/4throttle and WOT, then . . . what ADDITIONAL benefit do you think you'd get from another washer?

Not trying to blow you off, but . . . Googling, "Care and Feeding of the CVK40" might interest you.

Best wishes.
Nope I'm happy with how it runs but I have seen alot of guys ran two washers after they did the exhaust. I haven't ridden it with the L mod done. I just figured since more air is going in and more exhaust will be going out that the fuel mix may have to be done again that's all.

KLR Thumper Quick question. I did the .22 cent mod and the L mod and I run a [email protected] airfilter so it only makes cents to do the muffler mod next. I'm just gonna mod my stock muffler for now and down the road put a aftermarket one on. The question is now that it's breathing better should I add the second washer to the carb. It works awesome with one washer right now. If I add the second washer it will be .060 thick and I was told to keep it under .050.

Thoughts

KLR Thumper Yeah that's where the needle is. Well I put it together and rode it. Wow there was a good difference in throttle response. I lost a bit of top end I think. She had a bit of issues around 150 km but that's no big deal, it is also the winter storage gas with sta-bill in it. I don't run er that high to often anyways. But lots of good lower end pick up. I'm happy and the back firing sorta went away. I didn't notice it on my short 8 km ride and I rode it hard. Well it's done and running great. Thanks for all the help everyone. Now just waiting on my new centre stand, rear side guards and rear master cylinder guard to arrive next week and she is done until next winter!

Cheers.

terry_1956 Set your idle mixture screw out 2-2.5 turns out from lightly seated, still get some minor popping out of mine after mod. It does seem that some of us on here never sleep, lol
