carb boring...

[long gone]

has anyone out there heard anything about carb boring.ive heard of someone (on the track)taking their 26mm mikunis out to 29mm.i was told a lot of off road /perf shops do this type of work.i have a 78 gs 1000 w/ 4into1 pipe and have been running unipods but just ordered a set of k&ns.id like to do some top end perf work this winter.hopefully cams.would a dyna jet kit be of more use to me?also how far can you go performance wise before a welded crank is necessary?
thanks for lookin.

Here's a link on boring CVs. http://hotrodsbikeworks.com/tech/020...v_carburetors/ It's done quite often on all types of bike carbs.

I have heard of this also but I don't know of anyone who has ever had it done. If we want 44s, we buy 44s.

I would forget the upgrades and just enjoy it the way it is.

My sentiments as well. Too many ifs involved in carb boring. Start from scratch with the jetting.

thanks for...

the input and advice guys.thats why im on here.
im more concerned with upgrading the suspension and brakes at the moment.the bike is already altered appearance wise.more of an old road race/madmax look.shortened the frame and tail section up so it ends at the rear axle.gonna drill the rotors.id like to change out the front calipers to four pots.i hear the zrx1100/1200 shocks are quite a good adaption.also putting on an aluminum swingarm.doctor says i have an acute case of "cant leave well enough alone disease"hey im a modifier not a restorer.its in the blood i guess.

I would reconsider the drilling of the brake rotors. I have heard many stories of rotors cracking because drilling them makes them weaker. My guess is that the material that the older rotors is made of is not able to handle the treatment.

We used to do quite a bit of that back before race carbs were available in different sizes. Don't need to do it anymore.
