About 65 (phone GPS) or 72 indicated. I have a 2020 TT250, and I have a 42 rear sprocket. I have rejetted. Funny I decided to rejet again on my 2nd oil change. I lost like 10 MPH up top. I backed out just about everything I had done (went from 112 to 117 main, needle from #3 to #4 and from 2 to 2.5 on the IMS, and then went back). One thing I should have realized would have cost me tons was a switch from 10w30 to 20w50. I changed that back out too. Now the bike is back to what I mentioned in my first sentence. Oh yea, the miss I had at WFO, got rid of that by replacing the "torch" plug with a proper NGK.

Bike: BMS CRP 250
Fakuni 30mm, 110 main, 25 pilot Top speed: 60 on the dash.. so probably 55. And I was pegged, full throttle, slightly downhill. Shortly thereafter, my whole rear wheel flew apart. Nobody died! Gonna go to a 40t on the rear soon.. let's see what happens! I think stock gearing is like 15/50 or something Last edited by 420chonda; 06-18-2020 at 09:57 PM. |

Where's Azhule when ya need him! Didn't he set the Land Speed Record on his Bashan WILL? As I recall, there may have been a sonic boom when he did it.

I have a 42 on my storm and I don't think I would go any lower. Pretty noticeable loss of bottom end. You get used to it and it does knock the rpm down a lot on the top end.

Impressive for a 125cc! My first China bike was a crappy 125cc that peaked at about 45mph! |
