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 The previous version was outdated and no longer supported.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

TXC310r frustrations - engine backfire/cutting out

Hey guys/gals,

I purchased a husky 2013 txc310r two months ago - and for the first 10 hours of riding the engine ran great. Like a dream. The rest of the bike had several small issues that kept cropping up but I think mostly sorted now (fuel bypass line, every freaking bolt hand tight ha, etc)

The last two rides, the bike has run pretty poor. When the rear wheel leaves the ground, the engine makes a LOUD pop (backfire sound of sorts) and falls on its face for a brief moment. It resolves and runs fine/strong again while the engine is loaded with the tire on the ground.

This is really troublesome, especially through sand whoops where that throttle is all that is keeping from going over the bars.

Anyone have any ideas at what to look at? It seems its has to be the FI system or the ignition, the bike runs really well otherwise. Thanks for any feedback/help
 
Try reseting the efi by removing the positive lead from the battery for 15 minutes and reinstall. I am also interested to hear if you have made any modifications to your bike?
 
thanks for the suggestions - I will try resetting the EFI system.

The ONLY change that I have made was putting in a Ballistic solid state battery (had it on the shelf, why not right?)....which I have coincidentally found another thread on here where this battery caused another TXC310 rider to have funky missing in the engine. The battery was the cause of a momentary voltage drop to the fuel pump....

Link to thread/posts about the battery:
My Txc310 Is Almost Perfect

First thing (along with resetting EFI system) is going to be to switch back to the stock battery and see if my issue continues.
 
We use the EarthX batteries in all our 310s. They weight 1.3lbs and have their own battery management systems built in for complete reliability up to 8 years. No special chargers and no efi issues.
 
well - problem solved on the misfiring - it was the battery, sort of......

The battery i put in was from my yamaha WR, so the posts were in a slightly different locations. When i went to switch the stock battery back in, and pull the ballistic battery out - the battery shorted out on the subframe. issue found!

so, i taped up the battery posts good, tied in the battery more securly, and went and ripped yesterday. engine ran perfect. each time i would leave the ground the battery would shift just enough to short for a moment and make the bike backfire - then all was well again.



now, if i could just get the fuel bypass line to stop rubbing a hole every 3 hours of ride time. what a shite system that bypass routing is!!! any tips on this one?
 
the fuel petcock on the left side of the bike is SOOOOOO close to the water pump that it rubs a hole in the crossover fuel line. I'd just like to remove the stupid thing. I've already:
1st time it started leaking, cut hose at leak and re-attached while tank and all on the bike

2nd time it started leaking, took off tank, ran longer hose (by a couple inches) to move the line up some, installed a button head cap screw on the top water pump bolt (what rubs the hole in the line) and made sure to cover with the nylon sheathing when clamping down.....

3rd time it started leaking i just closed both petcocks and want to remove the stupid system. it drips right onto the header when it starts leaking, gonna end up burning this bike to the ground!


I just saw the spacers, i'll give them a go. hopefully that will solve or give enough clearance. I REALLY love the way this bike rides/performs but am completely underwhelmed by the fit/finish/assembly of my first Husky.

Tinken, thanks for the help :)
