MX with a Lectron
With all the talk about Lectron's making killer hp, I think I am ready to get one. I need to have my head rebuilt and am thinking of going with cams and a carb at the same time. I only ride mx and rarely dunes, and am wondering if this is the carb for this. I have heard a few people say that they are just for drag racing, but I need to control the throttle pretty good to keep from dying. If anyone is using this carb for mx, I would like to hear your opinions. Thanks.

there is no such thing as a dead spot on the bottom end of a TM carb. these carbs have an accelerator pump just like the top MX bikes comes with from the factory. the only dead spot they ever had was created by people who modified them wrong and gave them a bad name. set up right they are unbeatable for MX IMO.
lectron would be my last choice for MX.

yes I agree the Lectron can be tuned for awesome power all the way across the band, and it is king of drags from what most will say.
but its not the smoothest when it comes to slide operation and since MX is not about peak HP there are other choices that are better for this particular arena. the last thing you want is a slide hang-up coming up on a big table-top or double.
the kehein fcr's and mikuni tm's are just better suited.
RWR used to just be into flat tracks and drags, and the pumper for a killer snap off idle was not something they concerned thereselves with. the throttle return spring for these carbs was so stiff, since it was originally designed for a twist throttle, that they started selling the carbs with the pumper de-activated so that they could reduce throttle tension on the thumb. all this accomplished was giving the TM's a bad name for an infamous bog off idle. I've talked to two guys who have gotten mikuni's recently, and they both have the pumpers intact as they belong, and they claim their throttle tension is not too heavy. I can't say for sure, but it seems as though maybe RWR has developed new springs to work well with the pumper on a thumb throttle....
These same TM42's TM45's are being used on the YFZ, and from what I here they rock just as hard on those bikes as they do for the DS.

You might also consider EFI, it's a sweet little setup & might be a better alternative. No flat spots, throttle tension is fine, (I've checked.)
My Lectron is still my preference in carburetors, I've got power where ever, when ever I need it.

So, hightower, since the tm45 is the way to go and no one sets them up right, when are you free to come to Iowa and set it up for me[img]i/expressions/face-icon-small-wink.gif[/img][img]i/expressions/face-icon-small-happy.gif[/img]? The shop that does my jetting uses an EGA to get the air fuel ratio right and is it something that they could handle or do you need to find someone that has worked on these thing a lot before? The throttle pull is not a big deal because I am a big guy, but I can't as was said before have the slide stick shut going up the face of a 50 foot or more double. Thanks for the help guys.
