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 The previous version was outdated and no longer supported.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

10 hole vs 12 hole injector

I have a te310 with the txc ecu and injector. I have herd that the 10 hole injector flows more and I was wondering if anyone has tried both injectors back to back to see wich one is better?
 
I have the 10 hole. It was a PIA to get it to run right. Hogged way too much fuel into the engine and required lots of leaning out with a JD tuner.
 
The OEM ECU/12 port kits just work awesome and the 10 port you need to fiddle with and never seem the same,ECU works wonders,trust me.
 
It will probably be difficult to tune optimally even with a JD tuner. It would need a full-range tuner like the Bazzaz or PC5 with a custom dyno tune, or the optional autotune feature. Both are quite expenxive. I would expect the gains to be minimal, as the engine's needs are what they are and any difference between the two when tuned optimally, would be a result of better atomization between one or the other.
 
Hey MotoMarc, you seem to have good Mechanical Knowledge. I have 2010 te 250 first of the xlites, its been deristricted and I still have original 4 hole injector and ecu with stock pipe! I have ordered jd power tuner I have read about guys putting 12 hole Kawasaki injector in with good results. Was thinking of going this way instead of Huskys upgraded ecu & 12 hole injector and Leo Vince exhaust. What are your or anyone else's thoughts on this? Would stock pipe work ok if I just went huskys ecu & injector? Pretty happy with bike as is but do have probs when its really wet with a lot of popping and motor almost dying which I have read about yesterday with guys saying it is water getting on the coil and or water issue at injector connection.

That's probably best answered by people who have done it. Almost impossible for me to wing it and guess. If I had to make a blind recommendation I would say stay away from unmatched combinations. The Husky ECU/ injector will be easier to get dialed in than stock ECU and a different injector, etc.

12hole injector's main benefit would be better atomization and therefore improved combustion. Regardless of how much an injector "flows" they all will have the capacity to provide for the motor at full power. They are really quite simple just a coil that electromagnetically opens then releases the pintlevalve inside. It always flows at it's max, and the amount of fuel delivered is determined by how long the ECM tells it to stay on or open. Longer at high RPM's/large throttle openings. The injector always has 12v at the front side, and the ECM operates it by switching it to ground to open it, breaking the ground to shut it off. The time is calibrated precisely to the flow of a given injector. So switching the injector will always result in the need to change the ECM fuel mapping in some way, either with a piggyback tuner (PC5, Bazzaz, JD, etc.) or with a different or "reflashed" ECM like the Husky one.

Hope this is more help than confusing********************************************************************************!

In summary anytime you add a pipe or leave the tune that the ECM was designed to work best at, it will need mapping changes. As many people have noticed, sometimes the mapping as delivered is flawed, due to EPA regulations, production snafu's, or just plain human error.
 
Thanks for the info moto, it has been a big help! This maybe a silly question but would removing spark arrestor be considered as a tune change? Cheers Grant :thumbsup:
