Need a thread about air cooled 4st stuff

What was the difference between the TE and TX 510 ?
Are the air cooled 4t as mythical and rare as I'm less to believe ?
If they blow up are they going to cost 5 figures to fix ?
Well are they more expensive and harder to fix than an auto? Have an auto . No real problems there

Who's got one and do you like riding it ?
Cheers

i managed to get a pearler, 2 owners, ex husky team bike in excellent condition apart from a downish motor. The bike sat in a shed for 18 years but all the axles and nuts and bolts undo like new. the carb was worn and it ran rich down low but fanged big time. a mate owned its sister bike in 1984 and it was legendary and i was always on the lookout. i sold it as i found it was just to big and to vibey for me to hang on to and i was looking at a 2k motor rebuild to do the bike justice (heikki mikkola signed the sidecover at cd ). i rode it a few k's to a mates place one day and 3 fillings fell out ! Additionally, i had a mate who wanted to sell a Moto Villa, (pretty rare in aus) so the 510 went to a nice bloke who is giving it a birthday and it will be a ripper.

the te was the enduro with the shorter 10" suspension, wider gear ratios lighting coils etc while the TX was the MX with the 12.5" suspension and the 4 speed box.

here she is ...

i must qualify i am 59 yo and struggling with upper body strength. any one under 58 should get one....

TE was full enduro model to European spec. 10,5 inch suspension travel, lights, roadworthy etc. 6speed short ratio box.
TX was the cross country desert racer, USA spec, 12front 13 rear travel, MX type fenders, small light was an option. Wide ratio 6spd.
Both TE and TX ran 503cc with 91,5mm piston.
TC was the mx bike, same frame and suspension as TX, 4spd box, 90mm piston which gave it like 490cc and then legal to run in 250 classes in some countries.

These are rare birds, very sought after for Euro 4t mx classes, for which they are bastardised very far beyond originality.

Suspensions, wheels, gearboxes and some ignitions swap out with 2Ts. Clutch hubs and baskets too, though the 4t will not last with 2t clutchplates and requires its own sintered setup of which there is none NOS or remanufactured.

The true essence and character of these machines to me lies in riding a well sorted original, albeit with dual megaphones just to intimidate the opposition.
Racing a 500 2T Husky and 510 4T, back to back heats at VMX events as I did for many years, well that is a special experience.

Yes, their engines are costly to repair, parts are not exactly around in abundance. But then again a properly built, uderstood and maintained powerplant will go a long way.

Heads and cylinders are made news and bigger !

Thanks guys . You did not disappoint.
There is one local to me . Has a leapord print seat cover . And the exhaust has an X where the air box is then dumps out each side .
It's well known for roaring up and down the pits then getting a flat tire and not racing .
The guy does that a lot . Which is odd because he owns a dirt bike shop for fux sake. Might try rescue it from him one day

I didn't even realise there was 3 models

i forgot the TX or "XC" model

Jeebus that thumper is a grunt meister, it looked bloody slippery and that most likely worked to his favour, but that engine pulls from below idle it seems! Neither my 92 Husky 610 nor 95 KTM 620 from the past would pull from such low revs.
It is interesting how a camera can make things look very slow from the perspective of his camera, it would look much faster mounted lower.

His other interest with his bike is ploughing competitions!!

It would be great to combine the LC 510 four strokes here too, the "Older Single Cam" section is painfully quiet.
Tony.

I had both a TE and TX and it seems the gearboxes were both wide ratio.

Correct. The TC is the same 4 speed box as the 83 and 84 500 CR Twostrokes...

we got hold of ol mates bike in 86 and slipped cr forks and de spacered the shocks and it was a desert runner +. He rode it to 3rd place behind the two Honda australia riders at the Mallee Desert rally at Lake Tyrall. A great job as he was ploughing for 48 hrs straight before the race!

here is a look at the bike when i got it a few years ago now....
