Aprilia RS250 Help

**RS 250** · 29th May 2006, 23:40

I rode my RS250 around to a mates place and was there for a couple of hours. And when I went to leave my kickstart was locked solid and It won't budge at all. Now It's been sitting in the back shed now for a couple of months and finally decided to do something about it. Firstly does anyone know what could be wrong with it and where would the best place to get it fixed in the Tauranga area. It's been maintained well and only done a few months on new Pistons,rings, and Powervalves.

Hydrolock? Was it running OK when you rode to the mates place?

Could possibly be a broken powervalve moved into the cylinder when you shut down the engine.

I presume when you say the kickstart was solid, that you mean the engine was locked. Can you turn the engine by putting the bike on some form of stand and turning the rear wheel with the bike in top gear ? Either forward or backward? (Try carefully and gently , do not apply great force)

Yeah bike had been running sweet previously, Had no problems with it. The kick start wont budge. I can move the bike around in nuetral but havn't tried it in gear yet. I'll try tommorrow. Thanx for all the help guys.

Agree with Ixion, it could be hydrolocked (hopefully anyway). Pull the plug out then see if you can turn the engine over.

If it still won't turn over with the sparkplugs out, go to The Motorbike Shop in MacDonald st at the mount (behind GP Honda). Ph Ian on 574 2030.

What sort of 2 stroke oil were you feeding it?

It's been running on Motul 100% synthetic 2 stroke oil

**2much** · 30th May 2006, 23:52

so any success with getting it to turn over?

There are a few different recommendations for 2-stroke oil. Fully synthetic is recommended by guys in the UK (for my Cagiva Mito too) but spoke with a couple of shops here who recommend semi-synthetic as they said the fully synthetic is "too slippery" and doesn't lubricate well enough...Could be seized. (Want to sell

Woteva....
Sounds a crock of shit to me.
Any high performance two stroke should be running on the best oil you can get, namely a high grade synthetic.
A lot of peeps have a habit of running an oil that is too thick for an oil injected bike though. Most full race oils are designed for premix only so be sure to check the bottle.
If the oil is too thick the pump will have a hard time and the motor may not get its full quota.
Most shops these days have no idea how to look after high performance two stroke road bikes......comes with dealing with fuel injected computer controlled rockets I spose.

the only issue with running full synthetic, is that on some bikes the wet clutch plate doesn't like the oil. check the owner's manual for the recommended oil.

btw your RS sounds fucked. i'll give you a grand for it.
