Turning Wrenches / Re: RD250 to 350 questions,
June 04, 2026, 11:04:24 AM
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

Quote from: m in sc on September 03, 2025, 06:12:27 PMthe 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
