If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

How much HP?

How much HP will I have with my 78 gs1000, bored to 1085 with the Yosh kit, 33 smoothbores, Yosh header, dyna ignition and Accel coils? Not sure about the cams but they have adjustable gears.

An approximate number, say 100-120 HP?:pray:

100 max would be my guess. Going to need head work and big cams to reach higher I think

my Gs1085 put out 90Bhp 68lbs of torque with stock 28mm carbs K&Ns ,at the time it had 3 or 4 tight valves which has been done and it has Gs1100g cams, which were just about new which were dialled in on slotted Ape slotted sprockets..... But now its done a few more miles, I will have it done again soon,but I think with yours may be around 100BHP with those smooth bores fitted......

28mm carbs? Stock for the US market was 26mm VM's on the early bikes, and 34mm CV's starting in 1980. Heard some 1000S's received 30mm VM's, but never heard about 28's?

Assume you meant 68 ft-lbs of torque. Nice number there.:cool:
 
Just had my 83 gs 1100r on the dyno last week 90.9 HP and torque was 75lbs

Uk spec Gs1000s have 28mm carbs mine are nearly 29mm when you measure them with a vernier gauge, I think the En model has 28mm VM carbs as well. 68 foot pounds of torque" I did mean to say", the Guy who set it up for me has two Dynos one is in house which is where reading came from ,the other is on a lorry they transport around all over the country to race meetings and shows.He tells me that his mobil one,my Gs1085s would be around 100Hp.......
 
I forgot to add that it is also ported and polished.

That being said 100HP is going to be the most HP I have sat on with 2 wheels:clap:

Thanks for the replies,
Daryl
