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 😄

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

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

with the E20 fuel introduced in India, is there any manufacturer any where in the world making suitable grade Viton oil seals compatible with Ethanol for RD350.s ? 

Indian Rajdoot Yamaha is having similar front foot pegs

any suitable replacement spring which give faster return ? original part no 360-14131-00

BTW: your eBay link goes to the seller who sells the Kvedwulf supplied kits. I also bought 2 of these a couple years ago and paid about what you paid. The quality seems much better on these than others we've seen pictures of. Check out bottom side of cyl pictures and look at the sleeve match to cyl with no gap for example. I believe the sleeve looks thicker than others I have seen too. YMMV

 


Some will sell the cylinders without pistons at a price less 20-30 $

Correct. What is the advantage of that when you would then spend another ~$200.00 for piston kits? The beauty is the full kits delivered at a great price and not needing to spend more time & $ sourcing more parts that may or may not be compatible. I live in a small rural town with no shops that can bore cylinders to matching pistons for me and the kits filled a huge need for me. Of course, quality is extremely important and being choosy on which vendor you buy from is imperative.
