That I don't know!! they seem pretty good, I told him I cant get over 7,000 revs, told him a fair few people have had this problem and say its the timing on the back cylinder out 180....... he did say, then how`s it running then??? but least this wasn't the mechanic talking lol, surely a timing issue would be easy for them to sort out???

[AMCQ46]

the 180 out can be confusing, because that is at the cam, at the crank it is 1 full turn out.

it is the relationship between when the rear cyl is on its firing stroke and how soon before the front is on its firing stroke.... Each cyl has 2 TDCs so you can have 2 options for the relationship and in both cases it will start and run fine [at low revs].
but if there is only 1/4 crank rev between rear intake and front intake stroke, the airbox cant fill fast enough as the revs get higher and it runs out of breath at 6 to 7000

Erh ? Whats that you say ?

Well that explains it then The problem here is that not all mechanics are used to working on V Twins so think 4cyl. You'd have better luck going to a Harley garage They would at least understand. If you have the time then why not have a go yourself it's not too difficult. You'll me amazed the bike still runs with cams spun 180.

[craig77]

its in the garage as we speak, I told the mechanic, don't think of this a 4cyl, id have a go at anything but having just put another engine in it I don't want to wombles it up lol

[craig77]

MASSIVE thank you, to you all, got the bike back today and yes, the timing was out, a bit of research needed by the mechanic but all sorted now, full mot now I'm back on the road just gotta sort out the effin petrol leak it seems to have caught at the garage lol again thanks to you all, I was done with it but now sooooooo happy

result

[craig77]

cheers for the advice, it was a massive help mate

[VTRDark]

That's great news I bet the mechanic was pleased to learn something new too.

[craig77]

I bet he was, but id still be throwing money at it trying to get it sorted if it wasn't for all the advice you lot gave, I honestly cant thank you guys enough, and neither can my wallet lol and I'm one hell of a happy rider again it was nerve racking taking it for that first ride out when I hit 7000 revs i promised her all the treats in the world if you keep climbing, ive never smiled so much to hit 8000 then 9000 wooooooo hoooooooo hahaha

[bertye]

wooooooo hoooooooo hahaha indeed 9,000 plus up the slip road is just so sweat at full throttle .
