Just keep doing what you have been doing... start at the 2.060 and keep making 1/4 turn adjustments richer(SHORTER) and test after each adjustment. You'll probably also need to adjust the idle after each rod adjustment to compensate. If you were to go ... more »

Looks to me like you have it right. 3.75 turns from the starting point.. and the starting point is when the rod is threaded in just enough so no threads are seen. But all that is basically irrelevant since you already know what your factory set length ... more »

Looks like it snagged a ring on the power valve. The power valve must have been extended excessively into the bore. Might be something wrong with the power valve mechanism up top that allowed that to happen.

Ahhhh.. Honda design F-ups that could easily kill people. Good time to recall the 2013 rear hub 3mm sprocket offset. Yes, let's move the sprocket 3mm outboard but not change anything else. That way, old wheels will still "bolt up" perfectly fine on the ... more »

Added reply in a thread building lightweight wheel set 2/26/2021 8:27 AM

The 26" measurement on a bicycle tire is roughly the outside diameter of the tire. The 19" on a motorcycle wheel is the diameter of the rim at the bead surface. So it's not exactly apples to apples and the 26 actually ends up fitting pretty well. On ... more »

This is not really much of a challenge for you when you have the entire, vast knowledge of Vital and its recently improved search function at your disposal.

The wear marks are likely from the carb vent hoses, right? Do you think that was overpacked with grease and split open from hydraulic pressure?? Wow....

Added reply in a thread Replacing cases on 2007 cr250r 2/24/2021 5:56 AM

Honda cases are not a "matched set". You can replace case halves individually. The halves are not a machine fit to each other and use a paper gasket in the center. You should plan to vapor blast the old, right case as it is likely stained from years ... more »

Added reply in a thread Thoughts on these pistons, YZ125 2/22/2021 9:17 AM

Both of those are way lean and you got lucky I'd say. Full carbon coverage over the entire top of the pistons due to high temps. Ideally you want to be rich enough to have some piston wash so that the carbon does not cover the entire top. What do the ... more »

Added reply in a thread Is MAPP gas hot enough to take dents out of a 2 stroke pipe? 2/22/2021 8:58 AM

Yes, MAPP will work. As long as you get the metal cherry red it will be soft enough to move. Of course some dents can be creased hard enough or oddly enough that nothing is going to work. If you use oxy/acet you might just burn a hole through.

Added reply in a thread Aftermarket camshafts 2/17/2021 7:42 AM

I've had experience before where the combo of a HC piston and a high lift cam (stage-2) resulted in the need to run race gas to prevent pinging. Sure, you could remap it for pump gas, but then what's the point?

Added reply in a thread 2005 yz125 fire 2/17/2021 7:38 AM

Your tank might still be fine/usable. Likely what happened is when the bike laid over gas came out the overflow tubes on the carb and caught fire from footpeg sparks. The tank should be good unless the subsequent fire melted it. Take the tank off the ... more »
