Blown Engine - Sell Or Fix -2009 Smr510

I restored a repairable write off SMR 510 - 2009 model. Wasn’t much wrong with it, new footpeg, welded the exhaust. Anyway 1,200klms later it’s blown the bottom end.

I’ve been quoted $6k to repair and that’s if parts are even available.

Do I sell as is for hopefully $2k or pay the $6k to repair?

Hi, what kind of parts you need to repair the engine?

Not sure what’s needed, it’s at the shop.

I’d need to pay for the full repair, my expertise only covers servicing and light maintenance.

So for the cost I could probably buy a new 2nd hand bike.

Is this common for 2005-11? I bought my 07 TE 510 and the owner had a parts bike he picked up from his mechanic. It was a 2005 SM 510 with a blown bottom end.

What’s blown in the bottom end ? Is it the rod ? The transmission ? I would guess that 2000 would be high. I would run from a 6000 quote.

You can not say that is a "problem", because this racing engines have maintenance intervals, which require replacement of critical parts, the problem is when you don´t do it. For example a failure in a connecting rod can destroy the engine, and all manufacturers recommend replacing every X hours of use.
All brands with this racing engines are the same, KTM, Yamaha, Honda etc.. not only Husqvarna!

If you want to see the necessary parts I can give you my best price, I have many new parts and some used for this engines.

Yeah it started running rough and backfiring but I rode it another 200ks and it blew. I had it booked in the shop, but kept riding it. I should’ve parked it up for the shop. But oh well.

I’m in Australia, plus I’m not sure what’s actually blown. So far they’ve stripped top end and found some metal chunks from down below. Nest step is splitting cases and inspect. Top end inspection was $670Aud. Bottom end next is $550. Adding up quick.
