They sure do Bear,
dogs wear and forks bend enough to allow them to jump to the next(or several later) dog

Crikey! You live and learn eh?
Still, it seems strange that it's happening in most of the gears. That being the case the box must be full of shavings by now. I'd still be checking that sprocket at the front I think.

Did this start straight after?

Leonard.

I rebuilt it.
Has been working fine for several months .On the weekend I let it have it and thats when it started to jump.
I have pulled of the clutch it all looks well, except the clutch hub seems to move on the springs about 3 mm back and forth
.
Pulled of the sump to get my torch up into the gear box to see and it all looks ok nothing broken ,so Im guessing it is the selectors again ....anyone have a billet g/box laying around .....lol

sprockets look fine.
im putting to much load on it what do you guys think??

RE: Clutch Slipping - bear - 27-02-2009

Have you still got the BLT set up?


RE: Clutch Slipping - Maj - 27-02-2009

Clap Great launch, That looks like too much fun..
Still be surprised if all gears were going at once, but with something as unique as that your on less traveled ground.and it could be gears, but look at the rest of the drivetrain too.


RE: Clutch Slipping - Legend - 27-02-2009

Looks like a blast!

You guys into sand drags at all?

I'll ask again what size front sprocket are you using? Pm if its a secret!


Leonard.


RE: Clutch Slipping - bear - 02-03-2009

Looks like a long chain run, can't see if there's an intermediate gear to stop the chain flapping too much.


RE: Clutch Slipping - ashnery - 03-03-2009

Sorry been away
The front sprocket is 17 tooth the rear is around 48

I take of in first and cross the line in second
we only race 300 feet 90mtrs or 120mtrs depends on the track.
Got the sump of and clutch out ...as expected clutch all looks well.
took the sump of to get a better look at the gearbox and selectors they all look ok ,i guess im looking for a rooted selector ??
there are 2 chains joined togther to reach the rear sprocket .


RE: Clutch Slipping - bear - 03-03-2009

maybe stick an intermediate sprocket in there to keep the chain from whipping around too much.


RE: Clutch Slipping - Maj - 03-03-2009

17 skips easy, try an 18 or 19 and adjust your chain when rear sprocket is furtherest from the front to piano string tight..


RE: Clutch Slipping - Legend - 03-03-2009

You can get one of the shift forks out from the bottom of the sump if you need to check it. No need to remove motor.

!!I love you legend!!

Have decided to take it out again to do some more testing just to make sure it isnt anything in the drive train slipping .ie chain /sprockets rear axle,keep u posted.


RE: Clutch Slipping - BUSGO - 04-03-2009

Hey Ashnery. I saw you towing that beast through Lambton a couple of weeks ago.
I thought it looked fast on the trailer.
Also suspected it was a busa motor at the time.


(ya may have noticed a yellow cooper s dash up the inside and away)
