1983 ATC 250r Restoration

[yaegerb]

Ok that is great.... yea, at first I was a little worried when I picked it up, but you guys have helped ease my nerves about it and I am looking forward to this beast now..... I have become friends with the guy I bought it from (same guy I bought the 250sx from) and I told him about the 300r kit... he had no idea lol. I told him thats probably why the carb he had on it was not working right

Yea I really like these tires... I can't wait to try them out. I am kind of thinking about replacing my tri-z tires for these (I have Scorpions on it and can't power slide easy, but maybe thats just me not knowing how to ride!!! haha)

Is this what I should be looking at? http://www.ebay.com/itm/Carburetor-F...JYDXdy&vxp=mtr

Yeah, be sure not to tell him what that kit is worth. He will get upset at the price he sold it for

Thanks RIDE-RED..... maybe I should just got for a 34mm carb? I didn't get a chance to get out to the garage and measure the intake boot last night... but I took a quick look this morning and I am not 100% sure its not cut... probably has to be replaced. A quick measurement with my tape measurer on the way to my truck showed an outer measurement of 2 inches on the engine side and 3 inches on the air side.... but that is a very very very rough measurement

Having to buy a new throttle cable is no problem because I will have to do that anyway due to there not being one as of right now. I am hoping to swap out the entire throttle anyway for a twist throttle

If you buy an airstriker, Motion Pro has a cable with the correct ends for the ATC/PWK combination.

how difficult is going to be to install this 38mm carb if i got with it? Also.... Onetrackmind which cable is the one you are speaking of?

The 3rd generation 250R intake manifold will not work with the 2nd generation because the former comes out at an angle, whereas the latter aims straight back and is shifted off center about 1/2 inch to meet up with the airbox. If you want to go with a larger carb, you can use the manifold off a Honda FL 350. It is the same as the 2nd generation but accepts larger carbs. There are a few companies that sell billet manifolds, but they are pricey. You CAN use V-force reeds, reed spacers, etc. for the 3rd generation R on the 2nd generation as they have the same bolt pattern.

With the intake you have just buy the new boot that has the 2 bolts in a 38 mill size.Just make sure the one you buy has same bolt pattern.

This is what I had to use for my 85R, but now I'm not sure if it's the correct application for your 2nd gen R...maybe someone else can weigh in.

That's a cable made by Motion Pro, so they may have what you need if you call them.

The 3rd gen R throttle cable came with the carb top attached hence the need for a different cable. I see that the 2nd gen does not. I don't know if the 83 OEM cable will
fit the PWK, but it may be worth a shot.

hows the compression? do you know if the piston was drilled for the exhaust bridge?

Compression seems to be good. I don't know about the piston.... I am out here working on it now trying to figure out where to go next

Here is my current intake manifold....

That boot looks rotted. You can replace just that part. Either call Mikuni or search online. I bought one from my local Honda shop and one from a parts shop. The one from my local Honda shop they had in stock.You need to make sure the bolt spread is correct.

x2...electrical tape to hold the boot together is a good sign its ghandi. Also, from the pic it looks like you have a head leak.

[brandonlowe2]

Ok, I will check on replacing just the boot... I pulled that part off and will head over to the local dealer.

A head leak? How can you tell from the picture? That would suck a huge one.....

That top fin on your cylinder looks to be saturated in oil. Is it an optical illusion?
