Hello

Greetings from Hungary. I have a M800/VZ800 (2009). Just ordered V&H Twin Slash Staggered pipes with quiet buffles (wanted to hear some sound) . It will be fitted in a local custom bike workshop, they are building choppers and cruisers. However at the moment I keep the stock air filter they will check the fuel mixture afterwards to ensure that the bike is not running lean. I have already read several discussions here about it so already afraid of it:) They told if necessary they can do some modifications in the software but they think it won't be necessary. I will keep the O2 sensors.

I can share my experiences with the new pipes. Also thinking of learning and doing the valve adjustment on my own (maybe would make sense to do it before the new pipes and I don't want to leave the bike in the shop for overnight to cool down, it's not that close) looking for some procedure description...

Bikes I had:
198X Yamaha XS 250
1989 Suzuki VS750
2009 Suzuki M800

  Tom. If you are on;y changing the pipes then no action is required BUT if you also change the air filter then you will need to put a different timing unit on the bike as the standard Suzuki ecu won't play nicely with the exhaust & filter change. Likewise if you had fitted a K&N filter & then the exhaust then you'd need the timing unit. Leaving the 02 sensors fitted is a good idea also but you can fit a small wiring link wire or such to eliminate the readings fooling the ecu into thinking it still has the O2 fitted. Others on the site will tell you more than I can so please wait for them to answer your questions more fully ok?

Hi Tom and

hello tom and

Hi Tom 

 Tom

Thanks for all the welcome!
The bike is still stock but I plan the modifications:
-V&H Twin Slash exhaust
-Some more open air filter preferably in the original airbox
-Some gel pad fitted inside the saddle
-New mirrors, something different from the square shaped stocks
-Will get the Michelin Commander II tires, the 8 years old stock IRC does not give that much of grip anymore...

Even brand new the original IRC never gave much grip!

By the way a big  to the forum, and can I just say congratulations on your amazing English
