Turning Wrenches / Re: Needle Jet Question
« Last post by Czakky on Today at 08:53:53 PM »
I finally had a chance to throw in some leaner tubes. I went with the P2s on the 2nd leanest clip and it is definitely the best it’s ever been. There might be the slightest bit of a flat spot but I’m not changing anything until I get a longer run out of it.

Turning Wrenches / Re: yamaha rd250 frame with 400 engine
« Last post by stresa on Today at 06:27:00 PM »
Hans,
easy to see which model it is. First indicator is the frame number and the most obvious the footrest hangers. On the E/F they are attachted near the swingarm pivot. On the C/D the big hanger under the engine. 250/400 are identical on each model beside the frame number
Regards Uwe

Best thing is, he's not afraid to ride the wheels off of it.

Thanks guys

Uwe, yes that sounds good :) Its because i got a Rd250 frame, considering saving it ( getting it road worthy) but mostly have rd400 parts. So🤷‍♂️..

I believe Its a later model 250, but not sure. But frame looks pretty much idebtical to a 400 when eye Balling it

Turning Wrenches / Re: Doesn't seem to want choke
« Last post by pidjones on Today at 05:10:36 PM »
Took her for ~50 miles today. Hills, flats, curves, straights. Ran great! Shut her off twice for pit stops and she fired first kick. After cool down to cold pulled the plugs and they looked great. When first started this morning, she wanted choke (not for long) so I guess the repositioning of the choke and lowering the fuel level in the left carb did the trick. Still need to work more on the rear master cylinder. Might break down and buy a Chinabay master and a brake switch banjo bolt.

Interesting carb boots. And is that a front fender adapted for the rear?

Turning Wrenches / Re: Shift Shaft oil leak - RD400
« Last post by NYSingh on Today at 04:39:04 PM »
Had a drippy leak on that side because I buggered up the seal/cap (Part # 90338-22021-00) at the end of the shifter fork shafts when pushing them in, and fixed it by putting in a new one


I've seen Chuck solve this by filling up those 2 holes with sealant:

In any case, removing the side cover should reveal a trail of oil that should lead you to the culprit.
