It´s so fast, you can kill any 400. With mine, i´ve killed z400 and trx400
yes
Get a weisco 240 big bore kit
They are all 2 stroke 200cc motors. Unless you add a big bore kit then its 248cc
the bore size is 66.00 mm or 43 inches ? i think its the 1st , try looking at the sky then the ground before you try go go swiming
Stock bore is 42mm.
I have a 1998 blaster that's .40 over, stroked, and full FMF Gold Series exhaust.. I have heard them clocked at 85+ but mine has many many performance upgrades. If you bore and stroke your blaster, it'll kill about any 400 you put up against it, besides the YFZ450.. Which we all know would dominate any other fourwheeler.
The 620 is large bore while the 640 is medium bore.
Stock bore size 64mm Max 66.5mm
52mm
you could always put a big bore kit on it
There is not actually a production Yamaha 107. This is a TTR50 with a 107 big bore kit installed on it.
650 has 63mm bore and the 400 has 69mm ... don't think it would fit
