[barty5]

Anyone keen to do any or got anything they want to work on ???????????????????

YEP ME ME ME!!!!

As per my "broken CR250" thread, possible overhaul needed. I was gonna start tearing it apart today but if I can bring it down it'd probably be better to do so with all the parts strapped on still. Save me losing stuff :-p

You better order a piston kit mate.

just a thought on your CR, could it be the reeds?

[B0000M]

well, ill be there. i think i know a thing or 2 about how to pull apart / put together CR's

Yeah I was just thinking that. Will get on to it. Would it be easy enough to check by removing the reed block?

ive just checked with one of suppliers they only have the A1 piston in stock but i can phone in the morning and double check as online is not always up to date prob with a1 is its the 3rd piston so on an 05 with out it havin heap of heapp hours it might be tight. in saying that may be best to bring in strip down then order parts once prob found can always stay one night again next week to put back together.

Thanks Barty I appreciate it. Should I call Botany Honda tomorrow and get a price on bearing kits too? If its run a bearing it'll need replacing I guess.

i run pro-x in mine, standard size, mine's upto nearly 200 hours. check with scott411, his pricing is always good

Pro-x? Is this bearings?

[B0000M]

its fairly safe to assume your damage is limited to top end damage. whatever the case may be you will need a little end bearing (the one that goes within the piston) the gudgeon pin (the pin that connects the piston to the conrod), the circlips that hold the gudgeon pin in the piston, the piston itself, and the ring, and a base gasket. dont bother removing the head unless you've lost a lot of coolant during the last ride

thats
piston
ring
gudgeon
circlips
little end bearing
base gasket

I thought so but then thought 200hrs on a piston... that's a lot haha

i should clarify, its done about 3 hours on the current piston. i was meaning the engine in gerenal has done nearly 200 hours. suggesting that unless its done heaps more i doubt you'll need an upsized piston

[barty5]

my supplier brings in prox so i would guess scott is usin the same one so if they dont have chance is he cant get either can check for wiseco as well but not till morning there are cranks and conrod kits in stock though as well as gasket kits
strange there are conrod kits which do 02-07 and full cranks which seam to change through the same year range some changed ????

i know the cylinder is different, the piston is different, the 05-07 runs 1 ring vs the older ones running 2, different ports, diffferent exaust, different radiators, different jetting, theres heaps of small shit different. 05-07 is all the same though
