2011 TE310 failure (no hours count)

[robertaccio]

Well my bullet proof and very well dialed in blackhead 2011 TE310 has finally failed. About a month ago one of the valves stuck and we freed it with penetrating oil (we really dont know which one we just sprayed the heck into the intake and exhaust port and let it sit) well fast forward, she has been working great since that episode but prior to the stuck valve she sat for over a month.

I just did a complete tune up and a super nice clean up for the sale. Well, I had just been handed the check and did the paperwork. It started to idle strange and stall I adjusted it (never ever touched this before)
Sent the new buyer out with 2 other guys and he didn't come back. Got called out to rescue him found zero compression on the bike, Towed bike back in from the trail. Handed the check back to the buyer. Brought bike back to the garage and disassembled to find a stuck valve, pulled the head found bent/matched to the piston crown exhaust valve. #1 exhaust valve kissed the piston and bent.
I guess he is (oh he still wants the bike) getting a 2011 TE310 with a fresh top end!! Will send head assy and cyl to ZipTy for a head fix and light surface hone on cylinder. New top end gasket set, rings and valve/head repair. R

You really make me want a 2 stroke . Really though, sorry to hear that

I rode my buddies 2011 TE310 yesterday. It was a rainy day and when i was riding it (as he wanted to try my 02 CR250) it seemed to not idle right and almost wanted to die at times like water was shorting something. then I noticed when you really hammer the throttle in a gear high in deep mud it makes some nasty mechanical sounds in the motor. Like a cam chain or rod noise type thing. I mentioned this to him and he said it has always kinda done that. I really like these machines but they seem semi delicate.

Over $1,000?

 

[robertaccio]

x-lite=delicate is my key word.

cost? I will find out, truthfully it should not be that much. Labor is all me, just needs a head job.........

Landof Motards- I hear the ring dinger calling me back home again.....last one I had was a KTM250EXC (very well done with FC suspension and bunches of race ready/bullet proof stuff tacked on)

ps Motosportz-under load rod noise???ouch, he better think seriously about a ZipTy bottom end service and oil passage mod before the thing grenades.

 

[robertaccio]

my conclusion after all this husky love is that the x-lite was engineered as a pure racing engine. That means mega service at mega low intervals. How about tear downs after every race or close to that. Heck its an over square high revving F1 style machine that holds only 900cc of oil, that sort of spec requires lots of down time between ride times.
These things kick ace, they feel light, make good off road race power, the chassis is bitchen, but engine wise they are mechanically delicate (my opinion and conclusion from real experience).
So for all of you out there stay on top of service on your X-Lite based machine 250/310 series. These are not Honda XRs, Yam WRs (or fill in any of your bullet proof choices).
PS my 2011 TE310 has @ 2500 miles...my 2013 had alot less and needed a full rebuild before the end of 2013.
PPS ZipTy Racing has the data on bullet proofing these things with some add on proven mods (my 2013 TXC310R has been ZipTyd) and now the 2011 will have her head ZipTyd!

my 511 has 4500 hard miles and has not even needed the valve adjusted.

not sure it is rod knock but sounds weird. Only under extreme load. 98% of the time it sounds good and runs hard. This guy does zero maintenance. I think it has about 4000 miles.

 

[mnb]

what sort of mods bullet proof it?

I know of the clutch bushing thing, but nothing else.

 

[robertaccio]

you can ask details, but its like this. crankshaft mod that actually makes the oil move through like a KTM, its a ktm model year update ktm did to extend the bottom end life on their machines, and ZipTy has been applying the same to the 250/310 crank . heavier duty valves and springs. those sorts of things. hit up tinken for a q&a sesh

my 511 has 4500 hard miles and has not even needed the valve adjusted.

But what has it needed?

Oh no he didn't

 

[Mike-AK]

So assuming no major catastrophic failure, what kind of cash are we talking about to send an X-Lite motor to ZipTy for a rebuild and mod?

 

[Tinken]

my 511 has 4500 hard miles and has not even needed the valve adjusted.

Not a fair comparison. The 511 is a state of the art engine, seven years later, KTM is just now catching up to some of the fully titanium valved, dds, counter clockwise fuel injected screaming demon.

 

[Tinken]

Four basic things really transform the 250/310 engine.

1. Improved clutch mod which tightens up the clutch, removes chatter.
2. Crank oil relief mod, think Niagara Falls in your rod bearing.
3. Valve/spring kit, Husky used low quality valve and springs for some unknown reason. Valve stretch is eliminated and intake/exhaust overlap float is fixed.
4. ThinW40/stainless filters, higher flow of oil for the whole engine.

If we have the head apart, consider our 4 axis port, it's a massive increase to torque, but it's optional. One of my 310's has this mod and it out climbs the 630 on sand hills.

Exactly my point.

Thanks for chiming in. as for my 2011 TE310 see #3....as for valve float note I can open valves easily by pushing down on the keeper with my thumb.

 

[Motosportz]

But what has it needed?

Later,

oil, filter cleaned, tires. And recently a stator but i think that was a chaffed wire as it looked perfect.

How much does all that usually cost, in rough figures?
