22/41 gear ratio question

[Doc Harley]

The 22t should be good for another ~5MPH if you have the grunt. I guess the point of the 22t is that the chain starts out straighter and further away from that post so you have that more adjustment available.

5mph?!?! That's just what I'm looking for.

I have been running hurricanes 300hp tune with 22/41 for the last 10,000km on the same chain no issues. Stay on top of your chain adjustment and change your chaincase oil often. Putting a new chain on this season to be safe.

Right on! I just wasn't sure how to gauge stretch? Obviously when you put on the 22t you had to back out the chain tensioner adjuster 6+ threads.
I've got 4000miles on stock chain (stock power) the other day I added a bundle increased to 250-275hp this season.

If you replace a 21t with a 22t, especially on a chain that's stretched out. How & when will you know the chain needs replacement?
Also, I thought the 21t was good for 126mph?

I had a flash/tune prior to gearing up to a 22T.

Which tune & do you know what your top speed was with 21t?
I'm not critical..... gps, speedo?!?!

And I also needed a new chain after utilizing a 22T for a season or two!
Chain had stretched quick on mine with the 21T, so after putting the 22T and needing adjustment every 800 miles or so, the chain kept stretching so that there was not enough threads left on tension bolt!

New chain is stretching much the same!

I’m going to ask the same question as Doc as I’m in the same predicament. When do you know your chain needs replacing if you put a 22 t on to replace the 21t. I’m almost out of adjustment on the bolt. I don’t mind replacing the chain but not looking forward to adjusting for chain stretch 2 or 3 times a winter for the next 3 or 4 years. Mine seems stretched out now ( after 17,000 km) and i would like to just put a 22 t gear on and be done with it. But is the chain “ worn “ out.?
Just about to pull my chain case apart in the next day or 2 for the upcoming season and would love some expert device on this.

Keep the chain; it's now "broken in" unless there's obvious wear or noticable slop or play in the linkages. Go with 22t and you'll have much more available adjustment going forward, and it will need tensioning less often (once a year minimum check tho.)
