Hi All,

Newly joined this portal.

My bike originally started as a Bajaj Avenger 200 and has now been modded to that of an Avenger 220. For the last 7 years I've been using a 150/90/15 Michelin rear tire which after fitting on my custom alloy wheel would be like a 140/100/15. Due to that and on the stock Avenger 220 chain sprocket kit of 14/36/110 520 pitch set, my top end (with a Pulsar 220 BS4 carburetor tuned for power), I used to top out at about 125 Km/h. Unfortunately with the current restrictions on tires and the availability, I've been forced to used the HD Street 750 stock tire from Michelin which is a 140/75/15. Due to this my top end has taken a solid whack to the point that I can barely cross the 3 figure mark at 8000 rpm (I have the old Pulsar twin pod meter set installed). That has forced me to ground the "Devil" (nickname given by my kids) from highway running.

Thanks to this website and a post on the forum, I've been doing a lot of homework and calculations about what I need now to get the "Devil" highway worthy again.

Options available to me are to switch
1. The front sprocket with one of 15 teeth OR
2. A rear sprocket (6 bolts) with one of 32 teeth keeping the same chain pitch. I am even willing to get a 4 bolt sprocket and modify it to a 6 bolt sprocket as the last option.

I've been contemplating using the smaller pitch chains but the last thing I need is the power of my engine ripping up the chain and causing damage that I can do without.

I've been scouring the interwebs for the past week trying to find someone who sells custom chain sprocket kits but no luck.

Does anyone have any ideas as to who would make this and if someone in Mumbai actually has the expertise to modify an existing kit?

Thanks in advance
