ok so im working on a polanda right now. as of right now im getting the cylinder worked on... im having the front holes gussested so i can run the stock 250r studs.
once i get the cylinder back im going to mill it at school and make it all pretty!
but now here come all the questions...
1) what connecting rod should i use? is the OEM 250r strong enought?
2) I read that this will be a 389 at stock bore and stroke.... so will i need to run Youkon gears in the trans? im thinking i will...
3) I've heard of people running other pistons? can i run the OE polaris piston?
4) what size of a carb do you use... im looking for a good all around set up... i was thinking about a 38 or 39...
5) Is the exhaust port angle ok to mount the 250r pipe up or does the flange need to re angled?
6) what clutch kits do you use?
I could really use the help... I've searched and searched and i cant find the answers to these questions... i would like to get this motor build as soon as i can. i have a 85 tc bottom end that just needs a top end but every thing is OE in it and i dont want to trash it. i also have enought parts besides a clutch and a few other things for a 88 bottom end...
thanks for the help... if you could post pics of your builds that would be great!
thanks
