If a person wanted to restore a Valk back to stock configuration, how difficult is it to install a set of OEM carb needles? I'm fairly mechanically-inclined, but get nervous at the prospect of fiddling with the carburetion. Is this task doable by the average bear? Any thoughts or suggestions are much appreciated. Terry

You did say carb. needles, correct? Not the jets? If it's just needles your wanting to change, I'm guessing 15 minutes and no skill required. http://www.rattlebars.com/mtz/shims.html I think the needles are in this link somewhere, should illustrate the procedure for you. |

If you can't be a good example: be a WARNING!!

Yes, just the needles. As far as I know the bike has not been re-jetted - and the pilot screws look untouched. Terry

Why change them back to stock? They are adjustable if you're having some running issues.

Hi, Sandy. Here's the deal. I'm at least the third owner of a 1998 Standard that came to me with Cobra exhaust. While I had them on, the plugs were always a nice medium tan color - and the bike idled nicely and accelerated smoothly. After a short time, I tired of the loud exhaust note - and swapped the Cobras out for a set of OEM pipes. I also installed a K & N filter (without pre-filter), and had a local stealer tune and sync the carbs - which necessitated the use of multiple shims. Now, given the age of the bike (deteriorating vacuum hoses, etc.), these events may be completely unrelated - but the bike has never run right since. The plugs are now pretty dark - and my Rytek exhaust tips are dark and discolored; the idle is rough and choppy - and the bike is prone to cracks, pops, and gurgles upon deacceleration. Admittedly, I'm no mechanic, but taking things back to stock - and starting over with a known setup (and parameters) - seemed like a viable alternative to continued visits to the stealer. Before I do anything with the carbs, however, I've decided to do a desmog and replace any hoses. After this, I'll reassess the issue and decide whether carb adjustments are needed. Terry

sounds like a good plan to me. I went through the same change and it worked for me, except I didn't do the desmog....yet. Replaced all the hoses, etc and it's back to normal. Glad I saved the factory needles...have you seen the price of new OEM needles? ouch

If you have a 97, the needles are different from later years.
If it has adjustable in it, I'd just move the little ring around till it is good to go.
Mine is a 97 and I think I'm in groove 3.
I changed mine in a parking lot on a trip to California in about 2000.
