I put a hondaline bar for the 1800 on my 08 VTX1300C. I had to buy directionals for an 08 1300R to fit the bar. Then, since the directionals are mounted below the lights, they hit the front fork when I hit a bump. So, I bought Glen's 4" extension. I had to raise the MS windshield mount about an inch (good thing), and mount the light bar under the extension. Looks and works great. Glen's extension is a real improvement. The whole light is exposed and much more chrome is visable.
The bar would have been an easier fit on an R model. It is a real improvement for safety and appearance.
I put this mod off until I had the bike running good. Glen's A/F permanent adjustment tool and clutch relief were first. Then turn signal led indicators on the windshield followed by Roadhouse slip on pipes and then the Scar mod. Oh ya, I put a tack on to see when I was in 5th gear. I was feeling pretty good about everything so I did a pair valve removal and adjusted the valves. These are things I never would have tried without this forum. There are some great guys here and good instructional threads. The last thing for this year is going to be progressive springs.
