Rebuilding a Suzuki Step

[Oziex1]

Just started rebuilding a Suzuki Step 125cc scooter, why bother you ask? Well a hobby really.

As it's not compatible with modern gasoline, well I believe this is the reason why it pings all the time and has now burned the valves.

To recondition the cylinder head are there any options for valves resistant to the effects of new fuels.

Any links to websites for after marker parts for scooters in Thailand?

Replacement options for front forks, I know the kids put those flashy bling forks on, don't know if any improvement with them.

Big bore kits?

Cheers

Old rubber compounds are sometimes not ethanol tolerant,

but your engine should be okay with modern fuel like E10.

Blame burn valves on something else.

Good new forks might cost as much as the bike is now worth.

Have fun.

Your suggesting pre ignition does not burn valves?

Kinda.

I suspect you assumption is flawed.

Remember ethanol has higher octane than gasoline.

I doubt that your engine is high compression requiring high octane.

Does it "ping" with 95 octane?

"it pings all the time and has now burned the valves."

Pinging usually occurs under heavy load, not all the time, so maybe preignition is not the true problem.

Also pinging usually destroys the piston, rod bearings, etc, before the valves.

A lot of carbon build-up can increase the compression ratio or foster glowing carbon spots causing preignition.

But I doubt it.

Have you pulled the head off or looked at the plug?

How do you know the valves are toast?

How old is this bike that you think it is incompatible with 'modern fuels' ?

Sadly Suzuki is the least popular Japanese brand here.

I am guessing they only have 3-5% marketshare so no one sells hopup parts for that bike.

Your best bet was http://www.hispeedpiston.com/Suzuki/SuzukiThai/index.html but they don't list the Step.

not a good choice to play as a hobby as stated not many around and not many aftermarket support.

if you can, get a honda and you can find many aftermarket parts and modify it easier and cheaper.
