  • Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

125-200cc More praise for the WB 165

Just buy one I have a 38mm lectron on my cr 165 and after 1.5 hour race of a mix of very fast and very slow no spooge out silencer. I do think I might need to run race gas at 25% because at long wide open sections I do think I hear a little knock so I just shift up but it would be nice to just hold it a little longer so II do no damage. Plug looks perfect I have never seen a plug so overall tan. My bike does have 210 psi compression. I was thinking about trying it on my 2012 ktm 250sx but the bike already brutal fast for mx but I am sure the 38mm lectron would improve it even more
 
the 165 can be whatever you want. depending on pipe and setup. It is an amazing motor Walt built. I have ridden about 8 flavors of this motor now and they can be drastically different but all amazing.

my 165 - smooth mid range monster, 165, Lectron, Doma KTM 200 pipe, reed stops flipped for low end, PERFECT power for me

Blakes 165 - PC KTM200 pipe / Lectron less low and mid but screaming top end power, way more than 125

Brandon (PC) 165 - high comp head, race gas, fmf HUGE power, like a 250

it is simple to set this 165's up for whatever you need
 
My video ride on the Lectron test ride was 40 + miles of tight trails and I still had almost a 1/2 tank of feul left in my IMS 3 GAL. tank.No reason not to love this bike,even an old guy at the controls can have a blast on the 165.

Does it pull longer and is there more power ?

I was dealing with some knocking issues in the upper RPM due to too thin of a base gasket, so I can't comment on the longer pull. I will say it is much cleaner and crisper down low and overall the power feels more linear.
 
So what is the knock. I hope it not metal on metal and hope a little race gas can up octane enough to stop it.
 
It is likely "mechanical hammering" commonly called pinging or detonation....it's not metal-on-metal, but you are hearing the metal resonate from shockimpact. You can up the octane (it will tolerate the combustion pressures), lower the compression (will lower the combustion pressure), or retard the timing a bit (will lower the combustion pressure). In some machines / states of tune, just richening it up a bit will eliminate it.

If you run race gas you will eliminate the knock or even a 50:50 mix will probably do the trick. I run 50:50 mix of pump premium and 100LL av gas. Great combination and relatively inexpensive.
 
Before I had lectron with a mikuni being very crazy rich and lots of spooge it would still knock at very high rpm with high load. So I will try a 1/3 vp c12 mix with premium should put octane around 97-98 and see how it works.
 
Just a up date ran a 1/3 vp c12 mix this weekend and bike quit it high rpm knock. It did seem a little less crisp not a lot but a little down low. Did not hesitates just not as crisp right off idle would richen up bottom end help bring back a little of bottom end snap. Thanks for help and hope this help anybody else with this problem since it worked for me.
 
I do have an issue with High RPM knock

I did put already 2 base gaskets in the assembling but when revving it open to High RPM I do hear the knocking sound

I am limited with my gas choice as I only can buy from the pump premium (octane95) and knowing that the chance is big its mixed with cheaper additives

or buying the gas from the countryside road while riding and that's the 91 octane with guaranteed mixed with cheaper additives

the lubrication I do is 1:40 but I am not revving it all out as the sound is not healthy

low and mid rpm is not an issue its only on the wide open stretches that you want to rev it out and all what I do now is modulating with the throttle

In one way happy that the trails I ride is 95% mid RPM work where the motor shines it best in my opinion

would octane boosters (only Wurth is available here) be an answer? not cheap though

I was praising the crap out of my 165 racing a 120 mile 7 hours ISDE this Saturday as it pulled me up 2000 foot silty climbs at 8400 feet. This motor just continues to impress. Awesome.

Which 2 gaskets are you running?

I tried octane booster in my KTM 200 and noticed no difference.
 
Octane boosters are a waste of time. The amount you have to add to actually significantly raise the octane rating is close to 50%. Then there are other problems using that much not counting the cost.
