Tank-slapper on a Hyobag 250

[hmurphy]

No they didn't take it for a ride, but they have offered suspension setup etc. and steering damper. I am taking it to a track day in November at Taupo so I shall see what happens there when I give her a bit of shit. This weekend I should hopefully find out if the oil was coming from the engine breather or not. Weather permitting though (need dry roads to go a little quicker).

Thanks for the continuing updates - fascinating. Surely the source of the oil should be easy to trace? Either the rear damper is leaking/empty or the sump has less oil than before?? You have noted that you always maintained your bike so any change in oil level should be easily seen?? (I'm thinking of installing a catch-tank/bottle for the oil breather tube on my bike just in case...)

Keep the updates coming...

The oil seems to just spurt out in one giant surge when it is in a lower gear and hovering just below redline and when I am throwing her into corners and uphills and downhills. Like on the Rimutakas. So tracing the oil is a bit tricky. But the oil is definately coming from the bike! No doubt about that. Cheers

It sounds like a compression leak at high rpm?? It'll be interesting to see the results of a comp-test...

Bump - any update hmurphy?

Handle bar broke off. No damage to bike. Frickin' crap quality and I am sick of it. The bike is an amazing commuter! But it is NOT a sports bike and should NOT be treated as one. By this I mean it can't handle a 4 hour long ride through corners and country roads. Bikes should get excited when they see the takas approaching.... my Hyosung get nervous and pisses itself all over my rear wheel and shakes in the front.

The bike is being traded in, no more Hyosung for me. I am already on a new bike. Much MUCH better quality bike. Took it over the takas today and it felt amazingly safe. The bike just stuck to the road where the Hyosung would have bounced and jittered.

I recommend the Hyosung for cheap and comfortable commuting, but it is not a sports bike.

So what did you get? The R6? Glad you have seen the light ......Hybags serve there purpose, but i dont think generally they are very well built.

I had a hyo gt250r and the pipe at the back is a breather pipe which is normal on cars and bikes and the oil is most probally due to a an overfill which isn't uncommon.
Ride Safe highsides hurt, I KNOW......

Haha I might share some pics sometime soon of my new bike... but for now all I will say is that it is a Yamaha

You might let people know where the bike went, or what its rego is, so someone doesnt end up with your buggered bike killing them.

Absolutely mate! The bike will be advertised correctly. I will only recommend it to people who need a good commuter pretty much. Cheers for your concern!

The bike will be advertised correctly.

snort, make sure you don't leave off the bit about it wanting to tank slap in a straight line at 100k's.

Thanks for the update hmurphy Have there been any conclusions as to the cause of the oil-dump and tank slapper problems? DJ

Nup. He's gunna ditch it - serious fault unresolved. Re-read above - he's going to "recommend it to people who need a good commuter." Cool ay !

Make fucking sure you don't buy it for your teenage daughter to lear, er, kill herself on. I think this one should go international - what say you ? I think the bike should be deregistered, pending an engineers report.

I asked for this deathtraps' rego, so we can track it, but no reply was forthcoming. Can anyone identify this bike ?

The bike has been said to look like a sports bike, but not ride like one. In other words it is a great commuter, very comfortable and nice for long cruises but is not suited for riding with a bit of assertiveness, especially over cruddy-ish surfaces. It has a great engine and set up, but to get the real quality of a great sports bike I was told to upgrade from the Hyosung.

I still recommend the Hyosung for commuting and for gentle rides. But I am much happier on a bike that will be more than happy when shitty roads are thrown at it. The new bike has a steering damper, excellent suspension, very sturdy frame, bigger tires and ergonomics that are suited for twisties!!
