Custom Reed Valve Cage 4 SS2 or F1ZR...

This is for those out there who wants to upgrade you're ride, SS2(in malaysia) or F1ZR(in Indonesia, Thailand and some others) bike, which is the same bike but called differently in different places. Not many people modifies SS2 or F1ZR nowadays since its an old bike and most people go for Four Stroke bikes... Changing d original reed valve to a bigger ones increases the performance of the bike by certain percentage... by the feel of it, it does have a big difference... performance increases drastically... most people use RXZ/125zr reed valve, which both of them is just the same... i don't know if there's other reed valve that can be used....

left is the RXZ/125Z valve that i'm going to use...
the right is the original reed valve...

fitting in d reed valve of these bikes requires some modification... procedures of doing so will be provided in this post... :P... but u need all the tools and materials required to make to make this customized reed cage... procedures of doing so will be explained in this post...hehehhe... :P

actually there's ready made for this modification(only one picture available for this item)... but its hard to get nowadays plus its damn expensive... :S... around RM4oo... and the cost for me to making mine is lesser than RM100... BIG DIFFERENCE!!! :P

he comes the procedures of making ur own reed cage...

wat u need is aluminium sheets(RM10 depends on where you get them from)



file bits... impact drill... vice grip... and whatever things that needed and as seen in the pictures later on..



but before that u need to do some measurements and make a template...



some holes drilled on the aluminium sheets according to the template...
must be damn precise btw...



drill holes to in the middle for the sheets and remove the middle piece...
btw before doing this, all the holes the was drilled on earlier on must be aligned properly and super straight... :P



after removing the middle piece, the edges will be uneven... it must be even and smooth... use the File Bit to file through the uneven parts...

next is to bind all those pieces together with a Metal epoxy... get the slow setting epoxy... coz it is bonds stronger....

this is what u get once u've stick them together... btw this is only the lower piece...
its just the same procedure for the middle piece...



the two piece on the right should be sticked together with the top left piece... which will make the middle piece... :)...



this is what u get once the is done and after sending it to the machinery shop to lathe (for super flat surface to avoid leakage) and make thread for the screws. ... it was around RM30 for that... next is to refine the outer sides...



the bottom piece screwed onto the engine... and the middle pice placed on top of the bottom piece...



the reed valve installed in... :)



the intake manifold installed... its basically a curved pipe welded on a flat square metal sheet... :)



carburetor installed... btw its not the stock carburetor... this is 34mm KOSO Racing Carburetor,,, which increases the peformance quite a lot as well... the stock carburetor is just 20mm throttle opening... 14mm difference... planing to get a 38mm Keihin Racing Carburetor... but i need to wait for that since its kinda expensive... :P

Well... this is only one part of the modification needed to achieve top speed out of a small engine... i've been through 200km/h on my bike with additional of some other modification to the engine... which i might probably post it next time... and going that speed for only short distance drag race... 400 meters... maximum is for 1 km... i dont dare go further than that coz i dont want my engine to blow... :S... good luck for those who wants to make this item... :)...

my drag machine... :P
