Help me save my A100!!!

**Str8 Jacket** · 9th January 2008, 20:04

Its official, I am a destroyer of bikes, particuarly 2 strokes! My poor wee A has been dying slowly for a week or so now and it needs some serious work!
It has almost no power now and is making a very strange noise. I pulled out the air filter in the weekend and cleaned it, I have replaced the spark plug to one step colder but will change it back to see if it does make a difference, though I really doubt it. My luffly man is gonna help me check out the timing but we need some advice PLEASE!
Im also gonna attempt a leak down test, but would also need some help with this as well please!
If anyone can offer some advice or maybe tell me where I could get some cheap parts should I need them, please let me know. I'll luff you forever and ever and ever!

and its very cool to watch!!!

Tell your man that he has a pm.

Ill pop over one day (as i do! Hope ya dont mind me :P) and listen to it. Maybe i can give you an idea

.

The A100 has no reeds its just straight to the carb (Speights bud told me thanks man)
So u can elimate that.
Compression Does seem a bit fishy.
Shove it in first gear and see if u can push it along easier than normal (A cheap man's compression test!)
Ive got plently of random type's of plugs from the pile i got with the two RG's.

I give ya an B8ES to give a go (assume u run that series) Ive also got a B9ES (Hotter) and a B7ES (Colder)
Carb could need a clean? Maybe u got some degreaser in it the other day when u were cleaning it or some crc that would probably block a jet rather well.

Its not leaking oil from the base gasket is it?

How much are piston and ring kits for them? Curious in case I ever get something similar

Still need to compress the mixture through the crankcase and back against an intake valve of some description (reeds, rotary discs sorry not familiar wuth A100's edit: see from above piston port motor) so while a leakdown test as us diesel riders would know it isn't applicable it's still a valid thing to check.

Hels, apart from the obvious piston and rings worn out or broken, decoke, sparkplugs etc.
have you checked the gearbox oil? I have seen the sealant between the case halves and the gearbox fail and the gearbox oil rises as it fills up with petrol/oil mixture.

This wouldn't explain any noises though, so I would be thinking you may have a collapsed/dodgy main bearing which would in turn cause the crank seals to leak and you notice a definate loss of power accompanied by some pretty scary noises.

The only other part to check is the big and little end bearing. There's fuck all else to go wrong in a single cylinder two smoker.

Hiya, i used to have one, bucket raced it, is yours raced or for puttering around on/commuting? What do you mean has no power? could be fouling in the exhaust which can get pretty messy on those things which sounds like you're going to deal with soon anyway. It could be the exhaust port as well as the muffler, i know mine was pretty choked up, but I'd do the muffler first, depending on how many km's the engines done it could be the big end going, or if it feels really flat then the rings could be flogged. Qualman knows the feeling with a big end going, something like it just doesnt lilke revving and wants to hold back like its just saying"no"? thats what my GPX did when it ate one of its big ends on my way to work.

. keep us updated

While we are on the subject of A100's - I want to buy a couple (cheap) and at least one has to be registered or have the rego on hold.... Condition is imaterial... cash is waiting

Yep, changed the gearbox oil a coupla weeks ago, the old stuff was friggin disgusting!

You're right though, there's really not to much that can be wrong. Im just hoping that it dont cost too, too much!

Quallman, Speights Bud, cheers for your advice as well! Looks like im gonna have a very bust weekend! Still gotta help Malcolm with his RG as well. Im not too sure *why* I lve 2 strokes so much!!!
