'84 Husky 500 Frame - Good Candidate for TT500 motor?

[hawaii-rider]

I have an 84 frame I was going to swap out my 500 XC motor into (my 83) but have always wanted to build a Vintage racer four stroke

forget finding a TE510 of the period....yikes...and i have found some solid low miles TT motors.

Anyone do the franken bike with the 84?

I picked it due to the head angle over the 83, so the girl will turn....

Ideas?
warnings?
Cautions?

Thanx

It has been covered pretty thouroughly perhaps six or more months ago.

edit later, putting an air cooled 510 motor into the white dual shock two stroke frame is what was covered. It seems I typed too soon.

Try the search function. I have the 88 water cooled one and it doesn't intrest me just seems the radiators are bigger for the four stroke bikes and there are less fins on the four stroke bikes air cooled, something doesn't compute. If I recall you need the engine or at least the head from a dual shock one as carb location isn't the same even though they both are air cooled.

Not so quick, Motosportz Mike lives up there near you and has one he might let go. Pretty good shape too. I will point him here.

I do have a 1987 & 1988 husky 510s but they are both the liquid cooled models. Let me know if this interests you.

crap i thought the 510 I found you was air cooled, my bad.

The Husk frame was what the orginal Hallman TT500 was based on. Should be a great project.

 

[Motosportz]

the TT motor is huge and heavy.

I have ridden a tt in a 84 frame, not bad, but the bottom cradle needs to be dropped a bit. probably turns better than my my 510, as its heavier and pushes the front.
A friend with a hot tt motor in a maico 81 frame rode my 510 and thought the 510 felt a lot "lighter" which i wouldnt disagree with. his motor has no flywheelwith a battery ignition etc.
I came off the 81 maicos to the 510 and I think you can say you steer the maicos with the front wheel and the 510 from the back wheel.

+ 1, they are made of lead and mercury. had one, too, too heavy to be serious use, but fun project no less.

The cradle is too short on frames after 1982. I checked an 83 CR frame and found the cradle tubes would need to be stretched almost 2" to get a good fit

But they take up to 90% power increases and remain reliable

mainly cuz they make so little power stock. Huge motor with little power.

I was not being Nasty, they are 100% bullet proof, but SO heavy, all the weight is high up too, which makes it worse.

Mine had a free flow pipe, larger, jetted carb and open air cleaner, cam and it did go, hard, but did not turn or stop, it was like a dog on wet floor boards, fun but not fast.

 

[Motosportz]

Rotax's air-cooled 500 engine is a good transplant option if you can find one. More power potential, lighter, bulletproof. The Rotax engines were used by several bikes manufacturers in MX, enduros, street bikes, and flattrackers. In comparision, the Yammy engine is an anchor.

ATK had those as well.

 

[hawaii-rider]

well, maybe there was a reason the four strokes of the period just didnt work...and...Im ANTI top heavy weight bikes....

hey, its winter...looking for a project----

guess I will keep looking!

its okay I have TIME...

Thanx everyone....awesome feedback!

dont rule them out - they are a lot of fun, and racing in 4 stroke vintage class is even better.

I built this one form a klx frame and honda xl 500 motor with yamaha 43mm front end. It took a lot of time but cost very little - but then i rode a 510 and it blew me away ! - sold this one below straight away and poured a ton of money into a wreck of a 510 (try find a cheap head!!) - worth it ?- absolutely! I was a die hard maico guy and husky virgin until then , but i always wanted to try a 4 stroke for fun- the 510 will hold its own amongst the 2 strokes but as always 95%rider..the 510 is all about the motor..they are out there just depends how bad you want one! the motor just rocks in standard form compared to a xl or tt in standard form.

this is all you need all you need!

jeffs bike in the flesh. a watercooled twinshock frame with a shortenend and modified 86 swing arm

great fun and id say its turns better than my 510..why? 85 steering head angle, lower mass and heavier engine? another one built for not a huge amount of money..
Cool bike as all these specials are...

 

[hawaii-rider]

wow...what an awesome build.....

love it....
what tank is that?
old 125 YZ?

started with an 85 frame?
86 swing arm?

any frame cutting to get her to fit?

er ...correction an 84 l/c frame , yes a yz 125 tank and the cradle is about 2" lower than standard, i think!!

That is the main reason TT500 engines are transplanted. One guy in Australia did an article on how to make the stock frame handle like a maico while still weighing in at 280 lb. Someone else transpanted one into a Maico frame and still waiting to see if he finishes it
