Re: low to mid range flat spot

maybe if I keep it, bought it because of the elec start, hernia op in about 3 weeks so hopefully back on my Strada after that.

What model are they please, I will have a look and see what the cost is, I can do my own cables and brackets to steady them
Thanks barney

Re: low to mid range flat spot

Didn’t really want to go to the expense of that really, I guess it’s new cables as well ?

Re: low to mid range flat spot

IMG_1381.jpeg Ok upadate, vac ports added to carbs, ultrasonic cleaned, balanced at tickover and 2000 rpm, nice crisp pick up off idle, then took it for 20 mile thrashing, revs up to red line, rides fine if you thrash it all the time but if the rpm is between 3-5000 and gently roll on the throttle ...

Re: low to mid range flat spot

It has VHBZ carbs and has new rubber manifolds that I have fitted but not sure where the balance pipe would go, this would help me greatly if it had that, yes it does have a tail piece
Thanks barney

Re: low to mid range flat spot

Googling tells me that a 115 main jet should be .0455” I have a .047 drill bit that goes in easy so maybe the main jet a bit worn, interested in comments on this please, would this make enough difference ?

Thanks again for looking

Re: low to mid range flat spot

Thanks George very informative, carbs were balanced with a meter on the rear as there are no ports in the inlet rubber unlike the strada, so the tick over should be fine but when come off that it was done with wire and carefully adjusting cables so they feel spot on but not the best way I know, will...
