Can I use 360-60 and 361-60 together on a RD350 correcting the jetting? Any other changes required on a 361-60 carb when used on a RD350?

Since India is now adding 20% ethanol in petrol,do we have any manufacturer who makes ethanol resistant Viton, PTFE. FVMQ, FFKM oil seal, gaskets etc for our vintage motorcycles

Some years ago I bought a couple of carb gasket/o-ring kits for my 1988 FZR400 from this company in Thailand. The gaskets & o-rings were made of Viton. I don't see any older Yamaha 2-strokes listed but might be worth contacting them. They were very responsive and kits were shipped quickly.

Thanks, will contact them

What I do is adding STA BIL additive and use bigger jets. Ethanol free 100 octane fuel is available but only major cities

Thanks all

is there an India spec cylinders by Kveldwulf ? I doubt. He has one type which has exhaust port at 29.5mm.India spec is at 32mm. India spec original Escorts Yamaha cylinders were as good as Yamaha ones, if the liner is loose that means the liners are replaced by someone 

for 80 bucks its almost worth buying just to see how bad they really are, then just port the snot out of them and see what happens.

True 😄

Cheap RD350 cylinders now dirt cheap on eBay   never seen this cheap

I think I have 2 lefts and need a right... Like shoes.

I see them on eBay for up to $250.

IR8D8R

they do'not have right side ones

I think thext ones are longer but not sure

slightly longer ones are fine, the holding pin position must match

anyone making them for RD?

Can we use TX500 tank badge on RD350 tank? Both looks same with different color pattern

Wow #14 is an expensive one! When ordering make sure you get replacements with the correct features as some of these have circlip grooves in the OD, etc. The Partzilla diagram mentioned above has photos of the parts you can use for reference

The bearing numbers are listed in the specs in the back of the service manual.

ok thanks. Let me check it out

https://www.partzilla.com/catalog/yamaha/motorcycle/1973/rd350/transmission

Which part????

Part 31?

All the bearings inside the gearbox. I am looking at the numbers like "B6305N" etc

Can anyone help me with the generic transmission bearing no.s for the air-cooled '73 RD350

Thanks

the only ones affected would be the crank seals and they are what they are. im not sure of the materials used currently but us fuels are 10% and I've never ever had an issue. I don't avoid ethanol and its NEVER caused an issue. my 0.02

Yea worried about crank seals. It's 20% ethanol now in India. 0% ethanol is expensive and not available everywhere. I think all seals are not made if viton. There are issues like gumming, rusting, fuel lines breaking etc. loss of power is noticable along with fall in fuel efficiency. Any solutions are welcome. Thanks
