Good job on the pump rebuild. A very doable project for most RD owners. A couple of suggestions: 1. Be careful with the small pins that engage the gear ring. They can pop out, get lost, and ruin your day. 2. Don't lose the thrust washer on the pump drive shaft when you remove the pump from the engine. 3. Add a few drops of two cycle oil to help the seals slip into the pump body. 4. Watch your seal orientation carefully during disassembly. Take a picture or two as you go, so you can check your work. 5. It is a good idea to check the oil outlet springs and balls while you have the pump apart. Cheap to replace, if needed. Parts still available from Yamaha. Great idea for using clear tubing on the oil lines. The Yamaha autolube pumps work reliably well if maintained, providing the correct amount of oil based on engine speed and throttle position, rather than pre mix, which is either too rich at idle, or too lean at high rpm. Use a good quality two stroke oil and your pump will run reliably for many years.
@@chrisjamieson9300 hey mate I’m pretty sure it’s been repainted and it’s not the correct colour but the owner of the bike is going to repaint in the correct red.👍
Apologies to the owner but that colour scheme does not suit the F/G model at all sorry, still a great bike though all the same. As much as I love my own ‘Daytona’ style bikes, the coffin tank models will always be the ducks guts imho. In fact, I literally just picked my RD400E competition yellow set from my painter just this afternoon and it look simply stunning.
Beautiful bike, beautiful country and great flyby's! 👍
great job as always lad nice bike that one keep up the great work next video please

@@Scott-ph2yk great advice Scott thanks mate 👍 it’s been a long time since I had one of those oil pumps apart was a bit of a refresher.
@rechargegarage8705 The bike looks Great! I have a similar bike, Is the red paint job and graphics standard for 1979 models?

Thanks for the interesting video. Whereabouts are you based?
@@robg6485 Thanks mate I’m in Victoria, Australia 🇦🇺
@rechargegarage8705 Great, thanks for the reply. How can i contact you if i want some help with my RD400?
@@robg6485 hey Rob you can email me at krauszy@hotmail.com 👍
Is it not safer to premix the fuel and bypass the oilpump because the next time the oilpump give up your engine could be damaged
@@marcswinnen9100 hi Marc yes all my bikes are premixed I’m not a fan of oil pumps to be honest.👍
Ah... No !. Bearings need pure oil and two stroke mix with oil. Both.

@@markleadbeatter6196 he knows it’s the wrong colour but that’s they way he bought it and he’s going to repaint to the original colour.👍
