Premium Member blackout Posted November 2, 2020 Author Premium Member Share Posted November 2, 2020 I decided to use Tyga's silencers that are used on their VFR400 kit. The current plan is to mount one on each side just below the passenger pegs. 9 Craig Mapstone Upstate New York Link to comment Share on other sites More sharing options...
Premium Member blackout Posted November 3, 2020 Author Premium Member Share Posted November 3, 2020 Rizoma drag bars installed. The XSR700 uses 1 1/8" bars, necked down to 7/8", so options were limited. These are machined from solid billet aluminum, crazy stuff. As expected, I had to limit the steering with drag bars. This time I did it with a polymer 3d printed piece pressed over the frame stop. It's a snug fit and nothing else is keeping it in place. Time will tell if it comes loose. With the drag bars so low, I had to reroute the throttle cable and clutch cable, but all seems good. 4 Craig Mapstone Upstate New York Link to comment Share on other sites More sharing options...

Started by two guys from the UK that apparently wanted the business friendly environment of Thailand. Craig Mapstone Upstate New York Link to comment Share on other sites More sharing options...
stickshift Posted November 8, 2020 Share Posted November 8, 2020 Looks great! I've used Tyga exhausts before, good quality for the price. 1 Link to comment Share on other sites More sharing options...
Premium Member blackout Posted November 11, 2020 Author Premium Member Share Posted November 11, 2020 Both axle plates for the 8 inch over swingarm are mostly done. They are sized to accept 1.5 inch, .095 inch wall, DOM steel round tubing. (Drawn Over Mandrel). 1 inch tubing will be used for the trestles. Aluminum block washers still need to be machined along with the chain tensioning blocks. But that comes last. 6 Craig Mapstone Upstate New York Link to comment Share on other sites More sharing options...

VEXX Posted December 16, 2020 Share Posted December 16, 2020 Very nice work. One question (I'm not a mecanic, engineer or something, just curious) don't 2 in 1 in 2 pipes work better than ? Scavaging pulses or something? I really like the way people experiment on this forum, very nice to see and learn. 1 Link to comment Share on other sites More sharing options...

I really like the way people experiment on this forum, very nice to see and learn. Assuming you design a system that scavages, then yes, a 2 into 1 has benefits. The stock system does not scavage, so I'm not going backwards there. And hard to say how well aftermarket systems scavage. I feel the 2 into 2 offers the least resistance and with long straight-through mufflers (no baffles to restrict sound and flow), I'm hoping for some good performance numbers.

shinyribs Posted December 16, 2020 Share Posted December 16, 2020 Blackout, the pipes look great, man! "Designing" for scavenging and such...I know there's some hard science involved, but I think it mostly falls in to trial and error, especially in the home shop. A short while ago I hung a pair of CRF 250 mufflers on a slightly built XR400. Only because i thought it would look cool for a sumo to have twin cans. That engine ( single cylinder) had twin exhaust ports, so the stock arrangement was 2 into 1. The CRF twin muffler assembly fit up to the stock slip joint location, so I ended up with 2 - 1 - 2 by default. Given the stock muffler was wide open and notoriously loud, I was mainly shooting for looks and a quieter exhaust. Certainly didn't expect any performance increase due to flow alone. Surprisingly, the bike absolutely ripped with that setup. I mean, wheelies in 4th with no clutching up and high rpm throttle response was noticably improved. I had to up the main jet and play with the needle height a bit, but low rpm function was completely preserved. Lucky strike, but it was awesome. It's very rewarding to come up with your own thing and discover that you landed on something that works really good. Hotridding at it's core! Keep at it! 1 Link to comment Share on other sites More sharing options...
