I pulled down my motor today, seems she threw a rod doing some big damage to the bottom end but we will get her back on track :yes:

It really is no good when a rod damages your bottom end and results in an oily mess all over the place :innocent:

[Mental Trousers]

That's one of the main reasons I fitted a slipper clutch to my current bike. The insane amount of engine braking locking up the back wheel everywhere was the other reason.

Yeah totally needed one, contrary to belief the bikes been built on the smallest budget. There still isn't any in the budget for one.... ill keep hunting for the money tree. Shame both Jas and I were doing 36s on the last lap.

ever had bike on dyno and seen power curve ?

Slipper clutch is #2 behind suspension for best value for money mod. Sell something!!

[Tony.OK]

Shit I think you'd do 34's if ya hit an apex more than once a lap hahaa.........:crazy:

[neil_cb125t]

Yep - we have between 86-88RWHP peak on Ozzy Dyno at 9500rpm. Or we did have.... now its running on less than one.

Dyno chart attached for all you nosey buggers.

Tell me about it those carbon rims really make it hard to turn.;)

[sidecar bob]

Thank Christ it wasnt a sidecar that dumped its guts all over the track, pissed oil down pit entry & sat four riders on their arses.

They'll probably still get blamed

Looked like an oil trail already down the pit entry on the video?

lubrication is the key

hahaha there was a mark/line on the pitlane, but i don't think it was oil. I do feel really bad for those who went down in the mess, wasn't much i could do. The rod punched a hole in the bottom of the barrels right where the water jacket stops. Meaning high pressured OIL and Water just exploded everywhere. i didn't realize i was leaking anything until i slowed in the pits and i had oil from my toes to me knees.

Side note we got alot of abuse pushing the bike back to the pits - im sorry it went the way it did....when it let go we were doing over 150k on the GPS, the highside threw me right off the bike, wasn't till I landed back on the bike and I saw I could make the pit entry.

People expected me to be exploding myself, bottom line, we were racing well under lap record pace, smashing the crap out of everything we had, my bike broke giving its all. Its a shame but it was a test and we have found it needs to be stronger. well be back:yes:

[sidecar bob]

Choppa's going to turn up shortly & kick your arse publicly id say. He does when its us.;)
You got a lot of abuse pushing the bike back??? holy shit, I didnt know you'd actually done it deliberately up until now.

[crazy man]

going of your video the front axle was realy lose lol . at lease you and your bike can do the time (-:

Haha no id only do that if Neil fixed his bike with some fucken lego and went back out for race 2 and I crashed on the oil....

Bad luck man, those are some blistering times!!

It wasnt Lego, it was Play Dough as I heard it.

[craignzcd]

Thats Awesome cheers fella!!!

[wayne]

maybe time for rev limator at 9000rpm ?

[quickbuck]

Wouldn't have saved it......
Unless a limator does something different to a limiter ;)

Bugger bro. I was kinda hoping the ER6 would be stronger than the SV motors, since they go a tad better and are easier to transplant into other frames.

We measured one up, and it looks like it'd fit in an RGV frame, which are easier and cheaper to find than ZXR400s like your beast.

Well we were running std rods - the Je pistons and pins are heavier too - It was most probably rod stretch that got em, so it hit the head and let go. I experienced the same problems on my ZXR. ZXRs frames are a dime a dozen, I have 2 of them spare in my shed! but yep the head is narrow as, its the clutch and Gbox that's really large so we had to do some grinding in that area..... Allowing for the torque is the big one, rear end setup is proving hard as the grunt is smashing tires. But we are very close.

The mods we did at the start were fairly std issue - new motor is going to be built....and we'll do a bit more :-)

Some pretty severe downshifts old chap. Me thinks that is what made your motor dun blowed up.
