Hi Guys,
As you can see in my other thread I'm almost finishing my custom XS400. I wanted a café-racer styled bike with a clear/empty triangle with normally houses the airfilters and battery on a stock bike. All my electronics are mounted invisibly inside a custom built seat-pan. All cables were also modified or custom made to keep everything as clean as possible.
To achieve the desired look I went with UNI pod filters mounted directly onto the carbs, without the H-pipe. I’ve read and received advice that says the engine would run smoother/better with the H-pipe in place. My engine was rebuilt and seemed to idle and run fine on the testing table (just a few minutes at a time) with the standard jetting on the carbs, with the UNI pods directly mounted without the H-pipe. I don’t really care for reaching the top performance of the bike, I’m a pretty calm rider. So I’d thought I’d just start without the H-pipe, against all advice and just see how well the engine runs. I figured it couldn’t really damage the bike/engine and I could just go back and fit the H-pipe if I run into trouble.
But recently I read that not using the H-pipe could result in melting the pistons of the engine? What would explain this disaster?
I never considered that running the engine like this (stock jetting, air pods without H-pipe) could possibly damage the engine. I see a lot of bikes online without the H-pipe… how big is this risk? Again, I’m not interested in reaching maximum performance, BHP from the engine… I probably won’t ever reach top end of the bike or even rev it up to its max. I rode a Suzuki DRZ400SM (single cylinder) before and was quite happy with the power of the bike, I never felt I wanted to accelerate or drive faster (but single cylinder bikes are pretty fast to accelerate).
Do I need to be worried about destroying my engine?
