Yeah, finding a complete, even damaged 650, is a very good start.
If the head is repairable, thats a bonus, otherwise the 450 head swaps right over.

I doubt the cases would be hurt from a dropped valve.
You can either have the liner re-coated, if its oval, apparently you can correct this in a vise(carefully), or replace. I believe you can still buy them new from a Husqvarna dealer.

Pistons are readily available, Wossner is the way to go, it seems the ProX pistons aren't too strong, but they are very cheap,also mentioned earlier in this post. Or go big bore. Theay have some group buys on here every once in a while. Special order from Wiseco is Min 12 pistons I believe. With big bore you will need to bore the cases to accomodate a larger OD liner, and it will have to be a custom made liner. I recall someone's post saying that the standard liner can be bored up to 102mm I think, and re-coated, but any larger makes the liner too thin and weak, and you need to bore the cases.

I think the liners are too thin to bore out as they are, and I wouldn't bore a standard 100mm liner.

Carillo rod would be the best one to get.

The 650 headers only just clear the underside of the radiator, so you are good to go. The radiator is actually shaped with a liitle dent in the middle section to accomodate the exhaust headers of the 650.

Exhaust headers are different between the 450, 550 and 650, the collector and silencers are the same, but there are different silencers for FE and FC/FX etc.

Also, the exhaust systems are different from 2001 to 2004, to those from 2005 to 2008.


Older model headers cross each other before the collector, keeping the header lenghts closer to similar lenght, while the newer header didn't cross, so the LH header is much shorter than the RH header. Also differnt flange and position where the silencer connects to the header, but you will have no problem as both your bikes seem to be the newer type, and you have the 650 exhaust headers as well.

not true at all, infact, the valve head will bend the rod easily.

Taffy, the rod is bent on the small end and piston destroyed. I chose to buy the crank for the lower is all. It will need to be split & have a new rod pressed.
So thats pretty much where Im at. Looking for a few more engine bits & then its labor time This is gathering together quicker than expected so far

Well, I agree that a dropped valve will damage the conrod, but I was referring to the engine cases.

Unless the conrod breaks off completely, and knocks a hole in the cases, of course...

your right, it won't damage the cases. it will bend the piston over so far that the rod is gone and the piston shatters the liner.

a big end gone on the 05-08 engines will open the cases under the middle of the crankshaft too and let all the oil out the engine.

Big end on this crank seems to be alright.
So will be pressing a Corrilo or factory rod onto this crank.

Taffy, I want to purchase the starter fix for my 450, but might also be purchasing other bits from you to combine shipping.
Let me know about a rod, liner, piston kit, and upgraded valves please.
Maybe we can put something together

Thanks---Proflow

sure fella, I do a lot of stuff that might not be available anywhere else.

I have been developing my own alloy muffs and I even have 'packers' so a 450 can be a 550 or a 650 etc. I've got other stuff but it'll have to wait.

best to email me from now on please because Ally is in charge of pricing and I do the technical question. david@taffmeisters.co.uk

cheers

Well, heres a pickle

So as some of you know, Ive been enjoying my fe450 & looking for some parts to complete a hurt 650 engine.

Well I just found a local 06' 650 engine w/great compression & the water pump (mod) seal improvement done.
All else is bone stock. Comes without carb, pipe, ign, kick starter etc.... Dont need that stuff , got it from my hurt 650 purchase.

So heres the kicker, Is this engine worth 2000 US ? Thats a firm price minus he'll pay me 100 for my fuel to come get it.

Oh, its still in the bike till I start it cold & ride it. Then we spent a short amount
of time to pull it & I go home & stab it in my bike .

Thanks for any thoughts
