Author Message   Bluv21 Posted on Thursday, April 05, 2012 - 04:21 pm:        Hello. I was reading the installation instructions for the V&H exhaust just in case I wanted to install one. I was wondering, does this system require the exhaust port gasket and retaining ring as illustrated in the service manual? the V&H instructions aren't very clear on this point.   Gearheaderiko Posted on Thursday, April 05, 2012 - 04:32 pm:        Yes.   Bluv21 Posted on Friday, April 13, 2012 - 10:22 am:        Does the V&H exhaust for the Blast have a baffle? The description on dennis kirk mentions that there is baffle but I am skeptical... I had one on my old blast back in the day and don't remember a baffle. If so, is the set-up any different than the 0.5" shim, 175/45 jet recommended? Thank you!   Gearheaderiko Posted on Friday, April 13, 2012 - 11:32 pm:        No baffle, same set-up.   Bluv21 Posted on Tuesday, April 24, 2012 - 12:14 pm:        I am essentially at sea level (gulf of mexico) but have a V&H Exhaust and a stock airbox/K&N filter. My jets are are 45/175. Do you think this is too rich for the set up or do you think I need to mod the airbox?   Gearheaderiko Posted on Tuesday, April 24, 2012 - 05:03 pm:        Try the shims yet? Jetting will be close, only you can figure out if its right. First check your spark plug for blackness (pull it hot, after a long ride and if you havent used ANTI-seize on the threads, do so before you pull it hot and use a torque wrench). Better breathing is always good, but its not as if the airbox is choking the engine.   Bluv21 Posted on Tuesday, April 24, 2012 - 05:11 pm:        Yeah the bike runs well and the needle is shimmed 0.05" but I am just wondering if its running too rich. The last time I pulled the plug out was to check the timing but I haven't pulled it since I installed the V&H so I'll have to check it again. I guess I will have to try and see. IF I am running rich, based on the spark plug, should I pull a shim out before I down size the jet or should i downsize the jet before I pull a shim?   Gearheaderiko Posted on Tuesday, April 24, 2012 - 06:18 pm:        Either or. 170 and 2 shims might be better than a 175 and 0 shims. Or just 1 shim. Just change in steps, dont do it all at once. Fine tuning takes a little work and patience. But the difference with and without the 2 shims is often easy to feel. Again, it might be perfect or as good as its going to get without more involved carb work.
