Thought I'd start a holy war but asking. I'm playing with both carbs on both bikes. Anyone got any strong feelings about spending $150 for a Thunderslide kit for my M2's stock CV vs. $370 for an HRS42? Anybody been unhappy with either or tried both? |

The Mikuni rocks. I've got 'em on the S1 and the Road Pig. I've got no experience with the Thunderslide, but Aaron Wilson doesn't seem to like them very much: http://www.badweatherbikers.com/cgibin/discus/show.cgi?tpc=3842&post=58594#POST5 8594 That tells me something. AW knows his way around these motors, and he's dynoed a bunch of them. I'm inclined to listen to his recommendations. rt |

thunderslide is good for a guy what doesn't want to spend time sourcing individual parts and the like -- Aaron's (and other's) guidance will replicate (or beat) the performance increase for much less dough, though |

Well, I've said it before, the Mikuni HSR42 is the single best mod I've made to my S1W....and I've made a bunch. Al |

I went a different route and got the Screamin Eagle CV-44 and did the typical tricks (i.e. reworked the stock slide, jetted and shimmed the heck out of the thing, etc) and between that and the major head work and Knight Prowler cams, I get 101hp and 108ft/lb torque at the rear wheel of my 2000 74" X-1. If you are possibly looking to change the carb, check out Wood Carbs (www.woodcarbs.com). Bob Woods does some pretty incredible things with the cv 40, 44 and 51 units, plus the price isn't too far off a unworked Mikuni. BTW, with the mods that I have in my carb, I don't have any of the typical flat spot or rough idle issues that most cv's get!! |

Well, I ran the Thunderslide '40 before my HSR42 and the T-Slide is a HUGE improvement over the stock CV...for about 2/3 the cost of a brand-new HSR. I do find the HSR to be much more tuneable than the CV, and "seat-of-the-pants" response is much quicker. I agree with everything Aaron said in his KV post. I do feel the CV is probably a more "street-friendly" carb, as in, once you get the jetting dialed in, it's pretty much "hands off" as long as you don't change anything else motor-wise (we never do that, right?) It also autmatically compensates for altitude, if that matters. I'd have to go on one heck of a ride to get those kinda problems. For those of you who just gotta mess with things (Who, me?) the HSR has enough adjustments to keep you happily occupied for days on end, and (main) jet changes take a scant few minutes instead of pulling the whole carb (NOTE..pilot jets require bowl removal to change!) Which one suits YOU better, becomes the question. (Besides, the HSR can be had for a lot less than $370.00, if the truth be known) (Message edited by captainkirk on August 18, 2005) |

If you're gonna get a jet kit, the regular $75 Dynojet kit works fine...probably better than the Thunderslide. The Thunderslide can be "jerky" at small throttle openings, but is very responsive aside from that. I just purchased a Mikuni, and while jet and needle changes are very easy it is (at least for me) a tougher carb to tune. Other than that, it is far superior in every respect. |

I've heard folks mention a polished slide? What would this involve? I shinied up the tabs with some 400 grit. Not sure if it reduced the friction much or not - or if this was the goal of a polished slide. |
