Give Your Spree More HP

[martin@spree]

hello guys my name is martin i live in puertorico i hade about 30 sprees and i now all their little secrets 84 85 models are completely diferent smoler rod closer spark to piston gap and do run 38 to 41 in stock mode...for now i will tell you yust one trick...put a 84 or 85 cilinder head on a 86 or 87 model and you will get and xtra 4 to 7 mph.. i garanteed it ps some may get hot so use the gasket....

[darat]

wow we should try this

[xela_p2004]

I read somewhere that the 86 and 87 head were the desired head.

[martin@spree]

the1984 1985 head does not have a weld washer at the spark tread and the combustion chamber is flater wy do you think this to year models came whith low compretion piston for.....

[xela_p2004]

So your saying that the head of the 84 is better adapt to the piston of a 87? So when you mix a dome piston from an 87 with a head from a 84 it would increase performance, not bad, I might try that, what else you got?

[martin@spree]

try the head swap you wont be desapointed to free more power also ive done this home made header manny times....listen cearfoly first take a grinder and cut open the stock mufler by the middle take out all the chambers and fiber glass noise supresor youst leaving a big tube that it has inside at the end of the pipe and aiso leave 2 eanches of the small tube at the end of the pipe.. then wheld it ..you will have exactly the sound of a 2 cicle four track ..you might loase a bit low end torque but you will gain top end...ps it will be mutch noisier......the faster spree i saw back in the 80s with its stock motor and this and a few other tricks ran 47 mph.....and is no yoke....

Just received my 84 spree head today for my 86 spree, I will try it out as soon as my new tires and rim arrives so I road test it. I also ported the intake yesterday.

hey i was going to do that but everyone told me it would be a bad idea

[xela_p2004]

What was the reason for not doing?

[darat]

well do you have to use either a A or B jug?

[xela_p2004]

My scoot currently has a A jug on it and runing fine with out the 84 head, but I have a B jug sitting in the garage, which jug should I use for this dome piston small combustion chamber combo, A or B?

[myhonda]

What was the reason for not doing?

people said it could blow up if i did and i did ask more that just the people here. i got the few that said yea go for it but i had more people that said it was a bad idea

[xela_p2004]

Blow up? What does that mean, literally blow up, if its to high compression or not enough clearance? I would image if the compression is to high, just to increase the octance level, perhaps 93 octane, now if its a clearance issue I would say to bad wont work, However I will try it to see what happens. If anyone here has tried it with bad results please let me know before I destroy my engine.

[myhonda]

i dont realy know what would happen i have never tryed. id like to know your results thogh. can i reuse my head gasket?

[xela_p2004]

Dont know about the head gasket, I peeled my old one off and it came off cleanly, the only reason I would say no is because it is compressed. Anyhow sometime next week i will have my spree running, hopefully I can get it to keep up with my modified Honda metropolitan, so far it out accerlates it but is limited to 34mph, compared to my metro's 40+mph.
