Hey I got your PM over on ATVRiders and I guess I should have known better about the site sponsor thing. Anyway so I registered here and I'll ask again.

I'd just like to price out how much a complete motor rebuild would be for a stock 250R motor. Just replace all the bearings/seals/gaskets and give it all a once over. assuming nothing major needs replaced. There's 1 broken bolt (Way the hell in there, its one thats supposed to hold on the case saver. Damn!) And one stripped bolt (Also not good, one that's holding the kicker side of a case cover on.) Hopeing you could fix these while you're at it if you dont mind doing it. Other than that it should be good to my knowledge. Just needs a spruce up, Kinda giving you a general idea.

Also separately, how much would it be to port the cylinder? Low/Mid range type of porting for more trail riding. Maybe mostly midrange.

Let me know if you need more information, thanks a lot.

Welcome to the site & thanks for comming over.

Just a lite rebuild your looking around $1000.00
New Hot Rods crank, main bearings, seals, piston kit, bore job & taking it apart & putting it back together. Getting those broken bolts out could be a big problem, thats never good & will cost a bit more as well.
Porting price start at 250.00 for bottom end to upper midrange porting & drag is higher.

Is a HotRods crank recommended over an OEM one? They're still available right? I like the idea of a ported 265, easy to do on the stock sleeve/cylinder?

thanks a lot

Not realy, only if your price shopping & yes the long rod OEM crank is still available.
I've used a bunch of Hot Rods cranks over the years & only had one to fail. I've never ordered a short rod OEM crank but hear you cant get them any more, dont know for sure just hearsay.
Yes a stock cylinder 265 can be done, can even do a 270 if you want but I like to use the CR250R head instead of the TRX one.

I have no personal experience with either cranks or rebuilding a motor for that matter. But from what i've read it just seemed like OEM was more reliable from what people were saying. If i remember right, 86/87 were short rods and 88/89 were long rods? i have an 88 R. What year CR cylinder would be best? any machineing needed to the cases or head? Do you find its better just due to newer design/availability?

Thanks a lot for the Info

I think Neil was referring to a CR head not cylinder. And i have heard the same horror stories about hot rod cranks, but if Neil is saying they are alright i would trust him.

oem short rod cranks are discontinued .. some my be on shelves here & there ..
IMO a new long rod or a good used short(depending on application) would be a safer part
hot rods are still a gamble if ya ask me ..not saying they are no good .. just a gamble vs a sure thing

85/86 were short rods and 87-89 were long rod

Yes, just the CR head itself, not the cylinder.
There is a 265 build that uses the CR250R top end, but to my thinking its to much trouble for no more than what you get from it.
FTZ was who started the CR cylinder build, called it their hybred engine but its use was on mini sprint cars where the engine had to maintain 265ccs.

On the Hot Rods crank, like I say its an item for if your price shopping, ones made in Japan & the other China.
