Anybody running this gearing with a short 4th? Looking for input on good, bad, etc.

Trying to decide between the helical BGM and a straight cut Malossi kit for my 221 MHR build.

I have 23/64 along with a 36T (T5) short 4th in my PX210. I like that the fact that 3rd and 4th are closer together. I'm not impressed with the overall torque and speed of my engine, but it could be the Sito+ that i installed?

What do you think is wrong with the stock 23/65 ratio? 36 tooth 4th can help to close the gear gap but then you'll need a 24 cog to raise 4th back up again.
Depending totally how it's set up, tuned and adjusted an MHR 221 is anything from meh to mind blowing.

WDC, Sito+ wtf?

I'm using the Malossi 24/63 straight cut with a 36T 4th. The motor is Pinasco 225 and it pulls the gearing well. The combo of long gearing and shorter 4th is really good, certainly on a setup that is built for torque, rather than peaky power

How would you say this gearing set performs off the line, and down low? I've always liked the 36t 4th cuz you can actually get to 4th LOL, but losing the some off the topend is a bummer. Im thinking along these lines as well, for a torquey touring 225

The Sito's have worked excellent for me on all my stock 200 engines, so i figured i'd try it on my 210 kit. But i think that might be the thing that's strangling my performance. It feels as though my stock 200 has a higher top speed (as well as a higher RPM threshold) than my 210! My kit it definitely meh.

I'm running the 221 in VR-ONE cases with V-Force reeds. Factory matched and ported. Smart Carb 28 and BGM Big Box exhaust on the ends. I'm looking for a healthy medium between meh and mind blowing.

Really good all through the range (~7200 RPM tops in 4th), and it holds well into the wind and on hills (within reason of course). It's been on a 1200 mile tour with a pillion and luggage, and it performed remarkably well, but it's certainly not for the race track

Nice. Looking for that dependability with slightly higher rev range, not much higher though with the BGM exhaust.
