What bore is the carbs on a VTR 1000?
Re: What bore is the carbs on a VTR 1000?
As an aside from working on the Ducati.... I have been busy doing a job on my Harley V-Rod today...I changed the oil and filter and in doing that took the opportunity to check on the timing bolt in the engine that can come loose on some bikes, which wrecks the engine! nice and easy job, just drain the oil and remove the alternator cover which comes off easily. I checked the torque of the bolt before I removed it and it was tight... However to be on the safe side I removed it and cleaned both the internal thread and the bolt, and used some high strength thread lock on there as advised by the factory...

Loving the small details like the frame finishers on the Duke, excellent work all 'round Sir!
Insufferable halfwit.
Re: What bore is the carbs on a VTR 1000?
Thats one HUGE looking engine
the older i get,the faster i was
Re: What bore is the carbs on a VTR 1000?
it is! its a 1250 that was designed by Porsche for Harley... probably the best engine they have ever made, and quite powerful at 125 BHP... but the Harley traditionalists didn't like it
None Ducati this time, but with lockdown still in place I helped a mate out who needed some brake calliper pistons for a Norton Commando he is rebuilding...
I made two out of stainless steel for him as the originals were pitted quite badly... took a while to grind a tool to the correct angles and get the speed of the lathe right to get a nice finish, but I got there in the end...

This is a fantastic thread. I am SO impressed with the people who have the skills and persistence to do this sort of stuff. Not VTR related here is another similar thread on another forum.

I wondered how you got the smooth clean finish on the pistons. You friend should be over the moon,

That is rather amazing too. Has he ever done a write up on after the tune and how it rides or is it just a show piece?KermitLeFrog wrote: ↑Sat Apr 11, 2020 12:05 pm This is a fantastic thread.

carbon fibre everywhere (icing on the cake!)

Re: What bore is the carbs on a VTR 1000?
Thanks Ian
Gotta luv a bit of carbon and blended in with all the modern trick bits that's got to be a bit of a weapon
I've only ridden small 2 strokers, nothing bigger than an old X7, I'd love to try something like that. Especially with modern tires, frame and suspenders

Re: What bore is the carbs on a VTR 1000?
I raced a few TZ350s. Started on a twin shock model and finished with a monoshock F model. Using slicks in Oz and treaded tyres in the UK. They had between 60 to 70 HP at the crank but only weighed 115kg. They made decent power between about 8 and 11.5k pulling (just) from 6k with an over-rev to 12k. There was nothing superfluous on them. No battery or electrics (push start), no air filters, dry clutch. Premix. Cooling was controlled by how many strips of duct tape you put over the rad (first thing to be chucked out was the thermostat). So much fun. Like so many bikes I wish I had kept mine, they are worth a few bob now.Pete.L wrote: ↑Mon Apr 13, 2020 7:08 am Thanks Ian

That's a cracking finish you've got on the stainless, I always struggle with that. Nice to see a 'proper' micrometer too, none of this new fangled digital stuff!buzzer wrote: ↑Sat Apr 11, 2020 10:22 amit is! its a 1250 that was designed by Porsche for Harley... probably the best engine they have ever made, and quite powerful at 125 BHP... but the Harley traditionalists didn't like it
