Hoske silencer on '84 R80
I am putting the 38mm Hoske silencer on my '84 R80. It runs fine now. After installation do I need to do any rejetting? Thank you!

Snowbum has a page on intake/exhaust tuning...this might give you some ideas:

You may want to do what's called a "plug chop". This is done...safely...by running along in top gear at say 60-70 mph and close the throttle and kill the engine while safely coasting to a stop. When it's easy to do, pull each plug out and look at them...if they are very whitish then it's running lean; if they're blackish then running rich. This is all contingent on on what unleaded fuel now does to plugs. In the old days, with all the additives, plug color was a big deal. It might be changed somewhat with the latest fuels.

Fast. Neat. Average. Friendly. Good. Good.

To be safe do the plug chop as Kurt says. Run the bike at speed (65-70 is good) for at least 5 minutes before shutting down to check the plugs.
