Crossfire 150r stroker or swap to 250 doch efi?
 

Ok so i sold my favorite crossfire :( but got 700 cash :) but i already miss my baby :( So i got a couple of ideers floating around.....

1. 62mm extended cylinder, +6mm crank, big valve head, a12/a11 cam. But im scared to build up an internal reverse motor cause one of my 150r's reverse is already slipping even with no cable attached. ( any help on that would be nice)

2. I have a 08 xpeed 250i scooter with 7000 miles that seems to run good. It has a 250cc 25hp 4v efi motor that looks just like a gy6 150 just bigger. I think it would be an awesome power plant but....wiring....i hate wiring and id have to figure out what i need to keep and what i could discard to keep from having just a wad of wires everywhere. Also cant really find any info on the motor other than specs and its korean made. Also have to figure out reverse.....put reverse on my crossfire and cant live without it now.

3. Can get a honda cm 450 complete bike for 150 bucks.....Would rather have a 400/450 hondamatic tho. Also need reverse.

This build is happening asap. So any and all opinions and help will be greatly appreciated.

I miss my baby...next one has be even more bad ass.

Forums must be dead nowadays.

you cant do a stroker crank with an internal gy6 engine.

Thx thats good to know. Ive got several howits and a couple of HH motors

Well there u go, as long as they have external reverse ur set. I wouldn't really recommend the 6.6 stroker with such thin sidewalls but that's me and has been discussed alot.
