> Sunny's RX135 to RX170 Conversion

give some performance numbers now

it aint running. wont be running for a week now, me down with flu AGAIN

aww...too bad...get well soon

have lots of plans for teh big bore will get a custom made expansion chamber for a day n test the limits...

next step will be to get a RD connecting rod on a RX crank will bump up the CCs even more but i think i'll pass it on...too expensive for me

its done!!!

bore on right is teh beeeeg bore on right is my normal 5 speed one...try to catch the difference



010...first oversize...would have saved one more reboring opportunity if i had got the standard piston




Exhaust port...kept as per RXKing standards If you dont know what RX King is, see here Yamaha Indonesia

Its basically a RX135 5-speed with 18.5BHP instead of our normal 14.2BHP



Teh RX100 head from the gujri hehe very ooold








The head after its cut

All zoomed over my head a few posts back - but a worthy endeavor indeed. Hope you get to enjoy your fruits of labor very soon.

Post some more details man and also make it like a guide - just in case anyone wants to follow in your super duper footsteps.

Rename your thread title on lines of "How to Re-Bore Rx-135" "Sunny's Guide on Reboring Yamaha Rx135" "Rebore your Rx135 to Rx170" etc etc

WOOOHOOOOO!!!! BIG BORE IS BEEEEEEEEEEEEEG SUCCESS!!!!!!!!!

@dip : dont expect any tut from me this is highly classified info

Hehe great going Sunny, i know you cannot put a value to your hard work/passion/talent but still how much was the damage. < / > 20k - a ball park figure would be just fine

Also, so the now the PS would be 18+ and top whack at 130+ right ?

naaah....not 20K and all...would have been more like 5-10K...

I may be wrong though.... I hardly have any experience in this

20+ i believe

damages...ummm...4 to 5K totally worth it

there is still very very much scope to increase power ports are in just 4/5 speed config

EDIT : Bike has new title RDX 170

axctually.... 3.14*(6.417/2)*(6.417)*5.0= 162cc 30cc increase
