YAPI - noobie

mine doesn't whirrrrr but she whines like a turbo when revved.....I guess that's normal and is most likely caused by the camchain running over the guiderail.

Ok guys, I am not quite convinced or happy about the whirr. Any takers on a diagnostic? Water pump? Alternator bearings? Valve train? Clutch basket? Loose Straws?

( Please bear in mind that was a first start from cold in an engine that has stood for several years and spent the last quarter dry of oil and only run for about 30 seconds, before the carb change, two weeks earlier. )

If I recall right you did not tank clean the block/case in a way that all oil passages would be degunked of varnish from sitting.   Same with fuel system (clean carbs but what about tank, fuel lines, etc etc)

Thus before you diagnose anything, run engine oil cleaner and fuel cleaner thru it several times. For oil use the stuff you put into your oil... run the engine a minimum number of minutes then flush and replace with new oil.   Repeat this a few times.  then replace oil.... run it more..... but replace that oil too alot sooner than you normally would.  

For fuel... use in your next half dozen fuel tanks and change your fuel filters often.

IMHO of  course.

That's how the beast sounds .............run it !

you will soon love that sound as she comes up on the pipe at 8500 rpm in 3rd 4th and 5th ............

Thanks guys for your input and Mustang for your reassurance. Anybody else want to add what they believe the noise is? I know Mustang has the last word in all things tigger, but I'd like to hear of your opinions too. Does your tigger sound like this? The only time I have ever heard a sound quite like it was after replacing a clutch basket on a XT550. There was a unusual shaped washer plate ( part 26 in the pic below) on the primary drive gear that got damaged and so I replaced with another standard washer to absorb the tolerance. But it made that noise for another 30k until I sold her.

Anyway, so the noise is normal, but what is it?

[MtheTiger]

yours sounds pretty normal to me......could run somewhat smoother though when cleaned & filled+warmed up again.

[rf9rider]

Sounds better than mine.

I`d ride/run it in for a bit, then see how it sounds.  :)

Wahey.... you'll be out this weekend then  8)

What tyres you putting in there?

[BruKen]

Whoa tiger :D Still got to tune her then insure MOT and tax. Maybe the weekend following. Don't hold your breath tho, depends on free time. I will put conti's on her.

[BruKen]

mmmmmmm  :shock:

remember I was having a bit of a dispute withe the wheel rebuilder about the rear being an original 17 x 3.00 rim and he wanted to put on a 4.25. Kinda wish he had now. Tyre choice is limited. Oh they make them, just cant get hold of them easily and pay more for the privilege with less choice. Seems the common standard now is 4.25.

Oh well, had a choice of 3 that I could get hold of at shortish notice and have gone for the Tourances. I did like the look and reports of the Anakee 2 though. mmm, whata booger

[Geoff D]

Good tyres Bruce, got 'em on mine.... no complaints
