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 The previous version was outdated and no longer supported.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

Factory 340 kit for the X-Lite?

So twice recently I've read stories about a TE310 with a Factory 340 kit. I think one of the stories might have been about Cory Graffunder and the other was definitely about Glen Kearney.

So, apparently it's the equivalent of the old Athena 300 kit. Only it's a 340 kit for the 310. Apparently, it provides a noticeable kick in power. Not huge, but noticeable.

Ok, where do I get one and how much does it cost? This sounds like the way to bring the power up to the KTM 350exc. It'll still lack the wide ratio tranny, but I'll take what I can get. The luggability and extra power sound like a nice thing to me!

Odds are, it's too pricey for me. But inquiring minds want to know!

It would have to be a longer barrel + Con Rod etc im guessing, not just a piston and bore? Where did you hear about it?

Glen Kearney is an Aussie rider, I knew he rode the 310's but didnt hear anything about the 340cc kit unfortunately.
 
Also was this the X-lite or a cagiva engine? The Italian version shared many of its over spec'd parts with the bigger 450 & 510's, so it could potentially be robust enough.
 
never heard of it. The 2011 TE 310 with uncorked exhaust and JD tuner I rode was just as fast or faster (and feels stronger too) than the 2 versions of the KTM 350's i have ridden. I was very surprised by that. The KTM 350 is pretty soft on the bottom and even the mid. Not a bad thing but noticeable.
 
May 2012 issue of Dirt Action magazine :
340.jpg

I don't recall the details of the other mention I saw recently.
 
An 87mm bore cylinder would give you a 340cc motor without adding stroke. A KTM 350 is a 88 X 57.5 for 349cc.
 
Hey Walt, know anything about 4-strokes?!!
Everybody wants a bigger motor, I say twist what you got. But then I only weigh 165....
 
Glen Kearney rides for the the Aussie husky importer backed team in the AORC on a modified TE 250 bored out to 340.

Reading from Australasian Dirt Bike Magazine

- the 340 kit makes it real torquey, which makes it great in slippery conditions and realy easy to ride. It's still underpowered next to the 450's on a motocross track, but makes up for it with better handling.

- We based this bike of the 250 (x lite) because it has the v head and it runs the battery less Keihin fuel injection so we are saving weight. The fuel injection runs a custom map to suit the bored head and we dropped the rev limiter from 13,000rpm to 11,750rpm to stop the larger piston from breaking down

- converting the bike to 340 was expensive but well worth it

- the engine is a one of a kind and has modifications to almost every component

- it uses on average 30% more fuel


Took a snap of the article on the iPad (sweet looking bike) but haven't worked out how to upload from it, might do so l after on from the pc.
 
Yes sounds like TC 250-340 conversion not that one wouldn't be able to do it on a TE but EFI settings may require new ecu if using the Mikuni set-up. If its all done by bore (on a TC) when comparing to TE 310 may actually have less low end power. As would actually have less stroke than a 310. On moto-track would be fine, may not be best pick for off road for most who ride in mid and low rpm range. Don't think Glen rides too low in RPM!
For mere mortals like me, give me decent low end, meaty midrange, and a bunch of seat time!
 
The problem with building a 2012 TC250 to a 340, or building a 2012 TXC310 to a 340 with a TC head and FI, is just the cost. To start with a 250 you'd have to have a 310 cylinder, crank and a few othe parts. With a 310 you'd have to have a 250 top end ( head and vavle train ), FI system, ignition and a few other smaller parts to hook it all up.

Then, you would have to figure out how much meat the 310 cylinder has in it and if it can take a 87mm bore. If not, you would have to build a 87mm cylinder, which could be done a couple of different ways.

Then, on top of all that, you're going to have a lot of machine work and labor to put it all together.

The cost of the OE Husky parts is going to eat you alive. They want blood for things like cranks, cylinders and EFI's. It might be cheaper to buy both bikes, use the parts you need and sell off the rest.

If I was running a race team it would be a little easier, because I could get the two bikes cheaper and end up using all the parts on way or another.

But, just like anything else in this world, if you have the $$$$ it can be done.
 
Be best to take a 310 and put in the TC cams and ignition and maybe carb, but for me the TC250 has the perfect power for tight woods already.
 
I looked into a 290 Athena kit for my WR250X. Seeing the price made me think of a husky in the first place lol. Now of course they played with my head and didn't make a supermoto anymore, now of course they decided to release one again lol
 
I read this post and i just had to know!!

After a great conversation with PFG i am able to put some light on the topic :) It seems to be that the conversion is expensive! i would estimate that to get the same setup that glen runs you would need to have a spare $7000 and not expect a whole lot of change would come your way. This is because almost all the new engine components need to be hand made and thats even if you can convince them to do it for you as it took a team of their engineers to come up with the design.

Lets just hope that someone at Husky thinks its a great idea and puts it into production so the rest of us can get it :)

I read yesterday in the June/July issue of (what I remember as) Trailrider more about Glenns X-lite 340. Besides looking very nice he has done heaps to it.

He has a very swav integrated oil/water cooler (this looks practical for trail riders also), lowered bars, stegz pegz, akro exhaust system and heaps of other nice things
= $$$$$$$!
They use a power commander for the tuning chores, so I imagine a JD tuner could achieve a similar effect.

He runs the stock Husky hand guards, but I dont think he would plan on crashing very often..
