The only way to clean out a two stroke pipe is to put a stop (preferably a large rubber cork) in one end and fill it up with a caustic soda solution, the leave that over night before flushing it out with petrol the following day. CS is extremely corrosive and dangerous if you're not very careful, but it does a fantastic job of dissolving carbon from inside the exhaust. I do my RXS about every 20,000 miles.
An H100 is unlikely to need more than one such clean out in its lifetime The top end does wear very rapidly in my own experience, certainly out of all proportion to the modest performance, but as with any bike, the better you treat it the longer it'll last. On the plus side, the H handles very well and spares, even now, are plentiful, cheap and pretty easy to come by. |

No. Soda crystals are a water softner (sodium carbonate). These will not touch the carbon deposits on an exhaust.
You're after Caustic soda which is Sodium Hydroxide. This will dissolve carbon deposits, skin, aluminium, eyes, fat etc.
It's sold as drain cleaner. They do it in Wilkinsons among other places (most hardware stores/ironmongers will stock it).
As has been said it is VERY caustic and rather dangerous stuff to handle.
Mix it up in a plastic bucket, not a metal one. Always add the crystals to water while gently stirring and NOT water to the crystals, the reaction can be somewhat vigorous. It can be anyway so always wear gloves and eye protection when handling it.
Caustic solution gets HOT when it is mixed up. I've seen it boil if mixed too strong and too quickly.
You have been warned.
A potato makes a good bung for the end of the exhaust. Just dispose of it where some animal isn't going to try to eat it.
DO NOT PUT CAUSTIC SODA IN YOUR ULTRASONIC CLEANER. There is every chance it will dissolve parts of it. Even if it doesn't, the ultrasonics will aerosolise a small amount of the fluid. I dread to think what that would do to your lungs/sinuses. ____________________ “Rule one: Always stick around for one more drink. That's when things happen.

Apparently a big vat of hot caustic soda used to be a common sight in workshops for cleaning steel parts.
Remember not to chuck in some ally absent-mindedly though! |

My H100 was far nippier than the 250 Superdream I had after. The only really weakness with the engine is that the main bearing housings can wear oval, causes a nasty knocking noise but can be bodged with Loctite bearing fit as long as the damage hasn't gone too far. Oddly the worst case of this I've seen was on a mate's restricted MT5 (same basic layout as the H100 but 33% of the power) ____________________ 18:54:48 Rob Fzs: jews don't give away stuff for free
