hot start issues: where to start 2012 TXC310

I think you're talking about about a new ring and pinion gear? You're bike should have cone with the later hardened set. I would for sure check them before running out and buying a new set.

There was a certain segment of VIN numbers that US Dealers used to assess whether the bikes needed the parts. Later 13/14 models seem to have the newer parts. Check with your countries distributor. Was replaced under warranty for all affected bikes.

Just get rid of the starter....its dead weight. You'll have nothing but problems with it and it's not worth constantly messing with the valves and decompressor!! My txc310r fires up after fewer then 3 kicks hot or cold...and since I installed a rekluse once the bike is started I don't need to worry about it until I shut it down!! Plus I saved about 4 or 5 lbs of weight!!

To each his own. I'll give you it's a weak point for sure but I think having and using the starter is anything but dead weight. I also don't think you're looking at 5 lbs in savings. Per the valves adjustment with the decompression that's really more to help you kick start it.

I've got a 2012 with 165ish hours. 2 owners that have raced it. It's anything but a beauty queen. Around 90 hours I went through all these issues with it. changed out a lot of parts along with the starter. I've since doubled that in hours and it still starts with the starter. I try not to beat on the starter but when I'm racing you gota do what you gota do so I'm sure it will fail at some point in the future again.

I've also recently switched over to a rekluse I picked up at a good price. I can tell you all the parts to get the starter going didn't amount to what a new rekluse and basket cost. If you're putting one in a bike with hours you'll need a new basket as well.

Déjà vu and not of the good kind. I started this thread when the bike had 110 hours here we go again. Rebuild the top/bottom end over the winter 160 hours and shes got 180 after a few races this year. Out ridding with some friends and just on the way back to the van the sprang locked up when we stopped the bike for one reason or another. Got the home and pulled the fly wheel. The sprang was held fast to the back of the flywheel. Not quite as bad as Riche's who never gotten them apart. I did work around the pinion gear with the flywheel in a wood clamp and pry bars. It's interesting to note, once apart you could put them back together and it would spin. That said everything was grooved up.

Few things to note. When I went down this road the first time. I replaced the ring/pinion set starter as well as the woodruff keys and a few bits like new gasket for the starter. I took apart the sprang and inspect the flywheel but didn't feel they were that bad. I put everything back together, bike started and called case closed. I replaced the ring/pinion as that's when most were doing rather then replacing for need. I think really the solution was the starter but reading the many hot start threads I was convinced it was something other then the simplest solution.

This time things are a bit different. The big ticket Items that came in contact with the sprang are all grooved and I'll be replacing them. I've ordered a new flywheel, sprang, sprang cap, ring pinion, (you can't buy the parts along any longer) and starter. I also ordered new woodruff keys and starter gasket. I didn't pull apart the starter assembly but I think the smaller gears in the starter should be OK. In checking out part numbers I did noticed that the flywheel part number for 2012 is different then 2013 and 14. I'm not sure what change they made. I know the red heads do not use a neutral switch? the later model was also a good bit more money. I went with the correct flywheel.

Buying/finding the parts can be the next issue but everything but the updated ring/pinion set was in-stock with husky and I took advantage of Motosprts.com sale on dealer parts. They ran a 25-30% off list sale for about a week. I saved over 200.00. Love halls and my local guys but it's interesting that a place can run a sale on parts, I gota think Husky USA was ok with this. Would be nice if other places would do this once in a wile over the standard 10%. kudos to them. It look about a week to get the parts so not as fast some places but for the savings it was worth the 7 days.

The ring and pinion I found local and that should show up on Monday.

Very good pics on the subject N2B .... I shed a Husky tear for all these bikes and owners ...ESP since the Estarter on my 08 TXC250 worked flawlessly for well over a 1K HRS ..Still going the last time I tried it ... Never did a single thing to it except change the battery on the bike ... That's the elder engine bikes... Probably for deaf ears but just because something is new, that does not say anything for quality. Customers are the real testers to any newly released product.

With this round of issues I inspected the sprang a lot closer. The tricky thing is the wear that you're seeing in my hand is on the inside edge. So you have to take it apart and really check out each one as they all don't have the same wear. The other thing is I can put this one back together and freehand spinning isn't and issue.

Ray before this 310 its been about 10 years since I owned a Bike and my last one I just put oil in it and rode. It's also why I think guys in my area stick with 2 stokes. Live and learn. I'll keep this bike till the end of the season and see how it goes. The rebuilt engine is pulling as good as it ever has and at 46 it's more then competitive in the races I've done and for sure not the reason lost on wins. I've lost count of the friends that have dumped there 310 and some the brand. That said I'm not running out and buying a 8K new bike. In this area you're starting to see the 2014 310s be dumped on the market so who knows, one things for sure I can fix it so far and that's a positive.

Having pulled the fly wheel and starter more then a few times it was a rather uneventful install of the parts. Finished up before work today and the bike starts nicely once again. One note about the "new" sprang. in the past I just checked over the one installed and it's important to note which way it drops in so it rotates the right way. Well the new ones ONLY fit in one way. It's only after the wear can they be put in incorrectly.

Don't forget the 609 retaining compound before the flywheel is put back on.

Not a bad idea!

Looks good to me at least and I see that rekluse adjuster riding there ... The adjuster on my Core model is inside where the clutch plates are at .... But that another thread ...

Myself, I gotta believe that 310 is good engine, minus that starter ... Maybe I can buy just an engine in the next few yrs to fit in a a frame I have ... I'd settle for that 6speed tranny in those TXCs but only if 1st gear was lower than what is on my TCs ... If both models start with the same 1st gear ratio, that's not what I'm looking for.

That type of one way bearing is used on a lot of different bikes and is a problem on a lot of them.

What is that cable running next to the chain for?

gear position sensor

I think when they switched over to the red heads in 2013 they did away with them.

Great Post Ive REad Almost Every One Out There.
I Have Bought A 2011 te 250 And Im Having The Same Problems(Hot Start And Flaming /out)
,I dont Have Any Background I Don't Know If Someone Try To Fix It Before Hand
Did You Manage To Permanently Fix The HOt Start Problem ?
