Not sure what getting into but here we go 250r 1984

[jacobfour]

Picked up 250r. Bottom end seemed ok transmission shifted through all the gears clutch felt good. But it didnt hav top end so could not here it run. It came with tri z head lights original gold rims and some aftermarket aluminum ones as well so 2 sets of rims and tires got it for $400. but il need to buy exhuast, carb, and jug and piston. Any suggestions for a carb, exhuast, and top end rebuild kit. I know ebay but don't know much about how the quality is. I'm not looking for a screamer just getting running basically. Il post so pics shortly

Needs lot of work. Tri z head lights gold rims and aluminum ones forks looks like needs to be flipped around. But that's least of my worries. Gonna start ordering parts.

Looks like a good start to a good project.The 250r is a great trike.

[pipeline triker]

Yep thats a project, those rear rims, tires and hubs are off like a 400 ex or the like, good swap. Looks like the engine has been apart for a while. there are a # of 2nd gen R builds going on right now. Go through the build threads and get some info and ideas. They are great trikes. I am redoing an 84 right now. Find out what you need for engine parts and what not and make a list of what you need. Where are you located?

Need:

Carb, top end rebuild kit, jug, header, Reeds, intake manifold, air box and hoses, skid plate, Throttle cable, tail light, grab bar.

If I go to a 72mm Bore would I run into heat problems? I found a jug 71.8 mm bore.

hello

the carb size depends on the cyl porting, pipe, engine size and riding preference but a 36 mm is a good all around size for a performance bike or around a 32 for a cruiser.

the best deal on a carb is an old school mikunui VM style. they are around 75.00 new. even if you are marty hart or jimmy white you do not "need" a $200.00 Octo Port Dragon Slayer XXX 2000 made of Prefabulated Amulite because it ain't gonna make you any faster. Spend the money you saved on the beverage of your choice.

vm 36 ebay $99.00.

look here for the intake boot

also check mossbarger and boysen for reeds and intake boots or buy stock type reeds.

Yes, do it right the first time and buy one that is a decent 71 mm max. this way you can bore it when you get it and still bore it a few more times. if you use wossner, you might need to re-angle the squish band in your head.


you can buy orig cast pistons in the last link which are good. wiseco and wossner also sell them. also see pro x pistons and sleeves in the la sleeve link below.

No you will not have any heat problems with a 72 mill piston. I ran one for years at 72 mill and didnt have any trouble.A member on here 1upfront has a stock cylinder bored to 74 mill and he hasnt had any heat issues.
