Wanna put an 88 head on crf50

[rach88]

I have no idea... I just know I want it to go a little better and have a bit more pick up down low. What should I get or do? I've just pulled the head off my engine due to complete boredom and it doesn't seem that hard to swap a head over. Which one should I look at? I am a bit of a tight ass so I don't really want to spend more then $500.

tb head for sure

you will have zero down low power but heaps of top

why dont you just ask macca.....?

why am i getting the feeling somthings happened?

 

[Styv_Loosekid_21]

i have a braaap 88 basically your old motor but 2nd gear is gone? cheap cheap

I don't really wanna put a china head on it... That is my old engine styv didn't you get it off rhys?

 

[Hillz]

stock head, good pipe & carby will give you good down low power

 

[rach88]

I have a good pipe but stock carby. What carby should I be looking at? Also is there a carby I could get for now to see if I like it, but if I don't would work with an 88? if you know what I am trying to say.

where do you think they make tb parts? That said all crf50's are chinese now. I reckon a high compression piston would be a better upgrade

Yes yes... china v jap blah blah. I am not really interested in all that. I'd rather just not buy a second hand china head that is in a semi stuffed engine that has been around the block. Just wanna hear what people think, rather just buy a kit then just one bit here and there as then i have more chance of screwing it up.

CRF70 carby....

 

[motodevo]

you can pick up crf70(pz16) copy carbs for like 20 bucks off ebay, some guys even run pz19 copies on 50's. The place i go to in braeside sells pz19 copies for $15 cash. If using the stock head i would just open up the inlet on a stock manifold and taper it down to the stock size as the inlet on the head isn't big(like 13mm). The problem with running a bigger head on a stock piston is the larger dome on the head means you will lose compression and therefore lose low down power as said

 

[rach88]

where in braeside do you go? I'm only in mulgrave so not far from there. wouldn't the piston always been changed anyway if you change the head? I was just assuming i could buy a kit that would include head, barrel piston etc.

The Braeside joint is on the street beside Kumbak, off Governor road. I'd say who it is but their not a site sponsor. Starts with B, ends in LYGO. check ebay

yeh thats the place,its just a factory with no signage whatsoever, go there occasionally when i need little bits and pieces, he lets me go through the shelves and pick out what i want, doesn't have top end stuff and what he has this week might be totally different to next week, but always end up getting alot of stuff for whatever change i have spare
