  • 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 The previous version was outdated and no longer supported.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!

250-500cc Another Lectron question - cable routing

AA Class
Hi All

Lectron owners - quick question about the throttle cable where it exits the top of the carb. On the mikuni there is a tube guiding the cable out where as the lectron has a brass looking bolt and the cable drags across this on its way out. Might be over thinking it but should this be guided out or is there no chance that the cable could get damaged over time/use?.

Thanks in advance

Myles

I have not had an issue with the cable but Lectron does make one with a guide.

Thanks Kelly - that is good to know it is meant to be as mine is.

Thanks also for sending on the lectron too. Fired right up and runs great.. seems like the hot starting issue is long gone as I've tried it a good few times and no issues. I'm leaving it set up as it came as it seems good to me!.

Mine was very rich out of the box. The bike started good and all that you mentioned but as I kept leaning the Lectron I was getting better top end and it kept improving. I may still be a bit lean. Vinduro said to keep leaning out till you need choke when cold starting. But during the summer, cold is relative.

Cheers sarbortooth. I've a race on the 17th Aug so will see how the plug looks after that. I've run it around the roads where I live and the plug is nice and brown. Hopefully it will be the same after the race.. I'm not a full on flat out rider so mid to top end isn't yet within my skill set :)

I've not tried starting with no choke from cold but will give that a go to see if she likes that.. doesn't fight starting when using the choke though.. cold is definitely relative!..

Will update after the race, hopefully with a few good photos.

I just installed and had to modify the brass guide from the top of the old carb. Had a 45 deg. threaded into the top of the Mikuni. Cut that fitting to about half of it's length and slid inside the brass fitting on the Lectron. Cable was too short with it, and too long without it. Slides very smoothly. My carb was way too lean from the box. I think it's about right at 1.5 turns richer. May need more fine tuning, but is drastically better than the old Mikuni as is.

thats not WAY to lean as we made the bottom end ramp on the rod slightly more gradual so there is more fine tuning the bottom. I'd say these carbs should be within 2 turns of correct. So many variables with the bike and settings and fuel it is hard to nail but they should all be really close.

Mine runs fine so I'll get the first race out of the way and see where I go on leaning it out. If it is a bit rich it's not causing the hot start problem so the fine tuning will follow once I fully understand the carb and tuning it..

Thanks for that tip. I did wonder if that part was something I could modify to fit. Will have a ook at that tonight.
 
Not to hijack the this thread, but did i hear correctly that Lectron is working on a much shorter version to fit YZ125's which also used the TMX? I would definitely be interested in a Lectron which is a bit closer to the TMX size wise.
 

Actually my rod has 3-1XL on the face. Didn't the ones I've seen on here have MS3 on the face or are they the same? Very happy with how it runs so far. Will have to wait to get a good long run on it to evaluate. Currently 1 turn out on idle, 1.5 on powerjet so these are not out of whack.

yes depends on when you bought it and what you asked for. Sounds like yours is running good with the 3-1 and so stick with it. :cheers:

Yes done and tested. Fits much better and I made some changes to where the fuel overflows exit and how and some other changes. I have these in stock now all setup with various rods. Cost more due to the machining but fit better and work better.

Here are a couple of pix. You can see how read black side is cut clear into the body to make it as short as possible. also the Ball end is drastically shortened and sleeve for size. Fits really nice. Works great as usual. I also tried the three way adjustable 90 degree bend cable with great results on my bike. Also note how the left side overflow tube exits up instead of out tot he side which misses the ipe much more EZ. I was having to ziptie my overflow hose to keeop it off the pipe and now it does not even come close. Still evolving. :cheers:

With the new vent hose configuration, will fuel still be able to drain if the bike is dropped on the right side?
