107cc Head On My Crf50 :p

[wogtaz ryder]

well after riding on the weekend realizing how slow my bike is i swapped heads off my 107cc china and put it on my 88cc and it was a perfect fit not 1 problem!!!!! went straight on and it dead set started 1st kick!!!!

but ..... it doesnt run right obviosly , it starts first kick every time but will only run pretty badly for about 3 seconds then die , havnt played around with it much but hoping to fiddle with it tomorow some more

its still running the takegawa manifold wich is tiny for the heads intake port because the other one i got wont fit under the frame so could this be the problem? i wouldnt think so.....

Cheers

i'd say the intake may be the problem like you said ...the 107cc heads should be an e22 if it all lines up with stock cylinder spacing
what carb you running? may need to go bigger

 

[wogtaz ryder]

carb is 20mm that came with my TBR 88 kit and same with manifold.... what size you reckon 22 or 24 carby? mite buy a carby with manifold then

Thanks

 

[I_THUMP]

mite buy a carby with manifold then

Thanks

The shops must luv you

 

[SGONE]

20-22mm should be fine. you would probably need to open your existing manifold to match the port of the 107cc head and then play the jetting game to run your existing 20mm carb or buy a decent 22mm and go from their

Classic Honda 50's Australia - TB Intake Kit for Race or Ported Head (20/24mm Carbs) [TBW0273] this with my 20mm carby should be good?

Notice any power gains??

[wogtaz ryder]

ummmmm not really when i bought the engine came with no ignition so just got whatever to get it going ill try see if its still on ebay , it felt like it warmed up alot quicker , like didnt bog out so much when you first start it compared to another **** coil i had but thats about it.



nar cant find it probably not on there anymore

 

[50freak]

Prpbaly not worth it on a stocker??

Let me know if you come across a the link..

[matty06]

maybe you should invest in bar ends?

 

[wogtaz ryder]

maybe.....

 

[wogtaz ryder]

swapped manifolds and using the carby off the 110 i think its a 19mm?? starts idles nice and goes pretty well from what i can see so far will test it tomorow at the block and eventually get the 20mm carby going and then maybe sell this engine as ive got tb88RH coming soon... mite just put it in the china hmmmm

 

[SGONE]

cant wait to get my tb88 rh going...........

 

[jack_rides_stp]

Every one is going the rh kits,

Is there much difference between the rh and limited
