^^ if @Felipe the Ant comes to Cleveland this summer and has time to do internal work on my engine for the cost of parts and teaching me some of the stuff, I'm totally letting him have some fun on my engine!

Wayan and RacerX, I would appreciate if you can comment on my thread. I am looking at doing some similar work on my bike and have been told a few things by a local mechanic here in Jakarta. I am not sure if what he says is 100% correct and/or what you guys think is the best way to go. I don't care about the cash side too much (just looking for extra-testicles for my bike): http://www.ninjette.org/forums/showt...967#post581967

To achieve this I used a second hand Kawasaki ZZR600 cylinder block, removed 2 liners & had them retro fittied to the 250 block, then bored to 66mm to take kawasaki ZX6R pistons. I only picked this up this morning, so will be a while before I get round to rebuilding the engine. I'll throw some pictures up later. So yes doable, but expensive as the block has to be machined, to accept the new liners, because the original 62mm ones can't be bored to 66mm, not enough material. FYI the orginal liners are 62mm bore with 3mm wall thickness for 68mm OD. The ZZR600 press fit wet liners are 64mm bore with 3.5mm wall thickness, for 71mm OD. Now bored to 66mm so 2.5mm wall remaining. Those in the know say 2mm wall is the minimum thickness limit, so should be good. The ZX6R piston weight is similar, need to weigh them & designed for a similar max RPM (14K in the ZZR250), so should also be good. Last futzed with by Mohawk; February 20th, 2016 at 01:31 AM. |

But that's the case with the 04+ smaller gixxers right? The 750 is just a 600 with a bigger engine? In still making my way thru this thread, but is there a hands down conclusion? I started a thread for big bore kits and no responses, and this thread starts out saying there are none. The 500R 0-60 time is one, to 1.5 seconds faster than the 250. Can the 500 be out in a Or even 250? Is it plug and play? Everything connects right back up? |

The 500 may fit, but I've never seen a completed one. Nothing else will fit though, the carbs are bigger & wider spaced than the 250 because it has a central cam chain.
