Funny how this just showed up on my feed. Back in 95 I was at a garage sale and there was something under a blanket against the wall. I maneuvered on over to take a peek and there was a mint 74 rd350. Asked the lady about it, she said her husband was a salesman at a dealership, the bike had 35 miles but it never would run more then five minutes at a time so he brought it home and there it sat. I gave her $500 and a friend of mine found the problem of some factory welding slag shorting out the bike. Sold it for $2500 a few years later.

Great video! For my computing & electronics degree in early 90s, I designed and built a power-valve servo controller for my Ministock racing TZR 125, plus an LED rev counter. TZRs in the UK didn't have the controllers fitted and the valve was fixed in the closed position, you could also move it to the open position, but that then gave it no power at low revs.

I finally bought a 900R in the mid 90's and still ride now (S1000XR) but I never owned an RD500. Your video was truly fascinating and I want a 500 even more now!

Had similar experiences , owned a 250 LC in late 80's , great bike , was ex track bike so had had some tuning, then went to Australia , spotted an RD 500 in the paper and went to have a look , thought all my dreams come true but went for test ride and it gave off the most horrendous tank slappers when coming off the throttle, the optimist in me still wanted to buy it but so glad I didn't , would have killed me , think it was probably bent . Ended up with GPZ 600 instead, awesome bike , used to do Macpherson street racing at midnight after the pub, up through the chicane from beach , then 80 mph up to the roundabout, happy days.

I bought a red/black rd500 back in the 80's it was on a c reg, a quick test ride and it was sold, cost me £2300, i always wanted one but the £3500+ new price was to rich for me, mine had around 18000 miles on it and it was faultless untill i foolishly let the local jonah have a go on it and he came back with it running on 3 cylinders !, i pulled a plug out and diagnosed a holed piston, did the old screwdriver down the plug hole test, i also had a new yzf 750r so the rd 500 was left alone as quite frankly it scared me from working on it as it looked so complicated, ive stripped and rebuilt many of my previous and later yamaha 2 strokes, td3/tz/yr5/tzr3xvsp no problem ,.anyway i sold it as is for £1200 as i only had room for 4 bikes, so it had to go, leaving me with yzf750r/rd350b/tzr3xvsp/honda cb750k2, these last 3 ive just sold to my eldest son, leaving me with my yamaha R7 0W02 from 2000, i px'd the yzf750r for it in 2004,.if i had a crystal ball back then i would have hung onto the rd500, but i sold it to racer nigel bosworths brother, i also had a speed camera tkt for it years later (my name must have still been on the v5), so it must have been repaired ,. C730EMF was the reg,.not mot'd now on gov.co mot checker,.long live the 2 strokes !..

I have seen RZ 350 cranks with 180d offset pins and understand that the engine is treated as 2 seperate gas pumps in that layout. Then the other day i saw an RGV 250 crank with 0d offset crank pins. This must mean a shared crankcase/primary compression allowed by the 90d cylinder barrel orientation? So interesting.

@redtobertshateshandles5 ай бұрын
No. The timing difference gives one bank torque at lower revs for smoother power.
@razor1uk6105 ай бұрын
The degree spacing slightly improves tyre grip by spreading the would be twin power pulses of a cylinder per bank firing apart fractionally. Also the slight offset will degrade a sympathetic resonance from the cranks secondary weightings due to each cranks rotational distance from the other with regards to their input onto the clutch's drive gear, and torsional resonations potentially effecting long-term.. bearing lives, perhaps reducing a frothing effect upon fuelling and oiling to below a cavitational bubble generation range(s) level ?

@DoRC5 ай бұрын
I won't pretend to understand the actual physics behind it but I suspect that only one of the gears has a functioning anti backlash device because they found that they only needed one in order to achieve the goal that they were trying to achieve. Given that type of system will inherently add friction and will rob power they probably decided just having one was the best compromise. The other one likely has a dummy setup just so the two could be the same and use the same hardware etc.

I do not understand the per say 2nd oil pump. As the crank is lubed by the fuel/oil mixture and does not run in an oil bath per say like a 4 stroke. Only thing I can only guess is they are putting the crack seal(s) inboard of the main bearings so the 2nd pump would just oil the main bearing on the right but how does the oil get to the bearing on the left?
@thebracketfactory5 ай бұрын
One of the oil pumps is the 2-stroke oil pump as found on many 2 stroke engines. The other pump is a gearbox oil pump and specifically feeds the primary gear for the top/rear crank as that is high up in the engine and too far away to just be splash lubricated. I hope that makes sense!

A much bigger heavier bike with a £3000+ price tag compared to £1130 for the 350...It would have been Sooo much easier and better to have made a TZ500 replica with detuned barrels...
